It will be shown in this article that an ontological approach for some problems related to the interpretation of Quantum Mechanics (QM) could emerge from a re-evaluation of the main paradox of early Greek thought: the paradox of Being and non-Being, and the solutions presented to it by Plato and Aristotle. More well known are the derivative paradoxes of Zeno: the paradox of motion and the paradox of the One and the Many. They stem from what was perceived (...) by classical philosophy to be the fundamental enigma for thinking about the world: the seemingly contradictory results that followed from the co-incidence of being and non-being in the world of change and motion as we experience it, and the experience of absolute existence here and now. The most clear expression of both stances can be found, again following classical thought, in the thinking of Heraclitus of Ephesus and Parmenides of Elea. The problem put forward by these paradoxes reduces for both Plato and Aristotle to the possibility of the existence of stable objects as a necessary condition for knowledge. Hence the primarily ontological nature of the solutions they proposed: Plato’s Theory of Forms and Aristotle’s metaphysics and logic. Plato’s and Aristotle’s systems are argued here to do on the ontological level essentially the same: to introduce stability in the world by introducing the notion of a separable, stable object, for which a ‘principle of contradiction’ is valid: an object cannot be and not-be at the same place at the same time. So it becomes possible to forbid contradiction on an epistemological level, and thus to guarantee the certainty of knowledge that seemed to be threatened before. After leaving Aristotelian metaphysics, early modern science had to cope with these problems: it did so by introducing “space” as the seat of stability, and “time” as the theater of motion. But the ontological structure present in this solution remained the same. Therefore the fundamental notion ‘separable system’, related to the notions observation and measurement, themselves related to the modern concepts of space and time, appears to be intrinsically problematic, because it is inextricably connected to classical logic on the ontological level. We see therefore the problems dealt with by quantum logic not as merely formal, and the problem of ‘non-locality’ as related to it, indicating the need to re-think the notions system, entity, as well as the implications of the operation ‘measurement’, which is seen here as an application of classical logic (including its ontological consequences) on the material world.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Cambridge Companion to Early Greek PhilosophyPatricia CurdA. A. Long, editor. The Cambridge Companion to Early Greek Philosophy. Cambridge: Cambridge University Press, 1999. Pp. xxxii + 427. Cloth, $54.95. Paper, $19.95.The Cambridge Companions are designed both to introduce and to survey, aims that anyone who teaches introductory courses knows are not fully compatible. The Cambridge Companion to Early Greek Philosophy is successful because its contributors (...) have kept to a uniform tone of mostly introduction, with some reference to recent developments and controversies in the field. There are sixteen essays, with a judicious mix of chapters on particular figures and on general topics.A. A. Long provides a helpful introduction, discussing the problems of dealing with the fragmentary evidence for these philosophers, and giving an account of the nature and scope of early Greek thought. (He also argues—not entirely persuasively—that we should give up the nineteenth century name "Presocratics" for these thinkers.) Jaap Mansfeld explains the problems of sources and doxography (the chapter is quite compressed and could be rather overwhelming for the newcomer to the area), while Keimpe Algra surveys Ionian cosmology. Carl Huffman provides a masterful discussion of early Pythagoreanism, attempting to sort out what we can and cannot be justified in claiming about Pre-Platonic Pythagoreanism. The chapters on individual thinkers mostly provide systematic overviews. Edward Hussey contributes an exemplary chapter on Heraclitus, and David Sedley one on Parmenides and Melissus (it is good to see Melissus treated seriously), with Richard McKirahan weighing in on Zeno (mostly on the paradoxes of motion but with some attention to the arguments against plurality). The discussions of individual Presocratics are rounded out with Daniel Graham's treatment of Empedocles' and Anaxagoras' responses to Parmenides, and C. C. W. Taylor on the Atomists. Sarah Broadie considers rational theology and James Lesher early Greek epistemology, while André Laks surveys ancient theories of soul, sensation, and thought. Paul Woodruff and Fernanda Decleva Caizzi provide chapters on the Sophists, the former discussing Protagoras and Gorgias, the latter, Protagoras and Antiphon. Mario Vegetti undertakes an examination of the notion of causation in early Greek thought, and Diskin Clay explores the poetics of the Presocratic philosophers. The book opens with short discussions—three paragraphs devoted to life, sources, and works for each of the thinkers who figure in the period (in alphabetical rather than even roughly chronological order), a chronological chart, and a map. There is a large and useful—though necessarily selective— bibliography (supplemented in the notes to some chapters by references to articles that are not included in the main bibliography), an index locorum, and an index of names and subjects that [End Page 429] includes modern scholars "only if their views are cited in the main text or discussed in footnotes" (which makes it difficult to use in tracking down references). Unfortunately, as in all the Cambridge Companions, notes are at the end of articles rather than at the foot of the page, making necessary a fair bit of flipping while reading.How well do the contributors succeed in meeting the needs of the intended readers of the series? For the most part, very well; the novice reader will find this an accessible guide to Early Greek philosophy. The various discussions are solid and well-informed, and the authors have indicated issues and interpretations that are controversial (for example, Taylor takes time to consider objections to his earlier criticism of Vlastos on the connection between atomistic metaphysics and ethics, and Hussey is careful to note the traditional flashpoints of disagreement in Heraclitus interpretation). It is also good that some of the Sophists are included (it is worth considering how viable the traditional distinction between the Sophists and the Philosophers really is), and inclusion of both the medical tradition and the issue of poetics is very welcome. Further chapters considering in more detail the cosmologies of post-Milesians (including Parmenides) and on the philosophical uses made of the early Greek thinkers by Plato and Aristotle would have rounded things out, but these would have made an already big book bigger. As perhaps befits an introductory survey, most of the interpretations lean to the traditional - someone looking for... (shrink)

제논의 여러 역설들 중에서 후대에 가장 많이 논의된 역설은 운동 역설이다. 제논의 운동 역설의 종류는 넷으로 알려져 있다. 논자는 이 중에서 ‘반분 역설’과 ‘아킬레우스 역설’에 논의를 집중하고자 한다. 제논의 운동 역설은 아리스토텔레스의 보고에 전적으로 의존한다. 그는 6권과 8권에서 ‘반분 역설’을 보고하고 평가한다. 그는 6권의 답변과 8권의 답변을 각각 ‘질문자에 충분한 답변’과 ‘진리에 충분한 답변’이라고 부른다. 그리고 각 답변의 이론적 배경에는 ‘무한하게 분할되는’ 기하학적인 성격의 연속 개념과 ‘분할될 수 없는 형상적 연속’ 개념이 놓여 있다. 두 연속 개념에 기반한 두 답변에서 그가 (...) 사용하는 개념적인 도구와 학적 관심은 별도의 것으로 논의될 수 있고, 독립적으로 해석될 수 있다. 본 연구는 두 연속 개념 중에서 형상적 혹은 실체적 세계 이해의 존재론적 근거인 ‘분할될 수 없는 형상적 연속’ 개념의 해명에 논의를 집중할 것이다. 그리고 이를 위해 필요한 만큼 제논 역설의 전체 구조는 물론이고, ‘무한하게 분할되는 연속’ 개념과의 비교 분석이 제시될 것이다. 그의 세계 해석의 밑바탕에 깔려 있는 형상적 연속 공간의 구조를 분석하고, 이것이 제논 역설을 해결하는데 어떤 의의와 한계를 갖는지, 나아가 자연 세계 전체를 해석하는데 어떤 의의와 한계를 갖는지 논의할 것이다.

My aim in this paper is to suggest a new outlook concerning the nature of Zeno’s paradoxes. The attention is directed towards the three famous paradoxes known as “Dichotomy,” “Achilles and the Tortoise,” and “The Arrow.” An analysis of the paradigmatic proposals for a solution shows that an adequate solution has not yet been reached. An answer is provided instead to the question “How Zeno’s paradoxes emerge in their quality of aporiae?,” that is to say in their (...) quality of impasses, of problem situations without an exit, what is the original meaning of the Greek word “aporia.” It is my claim that this is the correct rational approach for solving these conceptual puzzles. In other words, I am not proposing formal solutions by criticizing and/or altering their premises assuming the continuous or discrete nature of space and time, but I try to draw the philosophical attention to the way we possess the phenomenon of motion as a result of the perception of space-time in human experience.

This paper aims to explore the nature of Zeno-machines by examining their conceptual coherence, from the perspective of contemporary theories on the passage of time. More specifically, it will analyse the following questions: Are Zeno-machines and supertasks coherent if we adopt the eternalist theory of time? What conclusions can be drawn from choosing the eternalist thesis, or the presentist thesis, when examining Zeno-machines? To this end, an overview of the opposing theories of time is provided, alongside the usual objections to (...) Zeno-machines and their theoretical foundations from Zeno’s dichotomy paradox. Keywords: Zeno-machines, philosophy of time, supertasks, Zeno’s paradox. (shrink)

Philosophy of science is seen by most as a meta-discipline – one that takes science as its subject matter, and seeks to acquire knowledge and understanding about science without in any way affecting, or contributing to, science itself. Karl Popper’s approach is very different. His first love is natural philosophy or, as he would put it, cosmology. This intermingles cosmology and the rest of natural science with epistemology, methodology and metaphysics. Paradoxically, however, one of his best known contributions, (...) his proposed solution to the problem of demarcation, helps to maintain the gulf that separates science from metaphysics, thus fragmenting cosmology into falsifiable science on the one hand, untestable philosophy on the other. This has damaging repercussions for a number of issues Popper tackles, from the problem of induction to simplicity of theory and quantum theory. But his proposed solution to the demarcation problem is untenable. Metaphysical assumptions are an integral part of scientific knowledge, inherent in the persistent acceptance of unified theories against the evidence. Once this is appreciated, it becomes obvious that natural philosophy, a synthesis of science and philosophy, is both more rigorous and of greater intellectual value than the two dissociated components we have today. What Popper sought for could come to full fruition. Problems that Popper tackled, from the problem of induction, to the problem of unity of theory, problems of quantum theory, and problems concerning the scope and limits of physics, all receive more adequate resolution within the new, fully-fledged natural philosophy.

Since the dawn of philosophy, the paradoxical interconnection between the continuous and the discrete plays a central rôle in attempts to understand the ontology of the world, while defying all attempts at consistent formulation. I investigate the relation between (classical) logic and concepts of “space” and “time” in physical and metaphysical theories, starting with the Greeks. An important part of my research consists in exploring the strong connections between paradoxes as they appear and are dealt with in ancient philosophy, (...) and their re-appearance in early modern natural philosophy, as well as in the foundations of contemporary science and mathematics. The way paradoxes are dealt with sheds light on a theory’s hidden metaphysical assumptions, especially with respect to matter, space, time and causation, it defines its ontological signature. This conclusion led me to the in-depth study of early modern natural philosophy, the origin of natural science, especially the influences ancient thinkers had on the new conceptions of space, time and causation developed by Newton, Huygens and Leibniz.

Unlike almost all other philosophers of science, Karl Popper sought to contribute to natural philosophy or cosmology – a synthesis of science and philosophy. I consider his contributions to the philosophy of science and quantum theory in this light. There is, however, a paradox. Popper’s most famous contribution – his principle of demarcation – in driving a wedge between science and metaphysics, serves to undermine the very thing he professes to love: natural philosophy. I argue that Popper’s philosophy (...) of science is, in this respect, defective. Science cannot proceed without making highly problematic metaphysical assumptions concerning the comprehensibility and knowability of the universe. Precisely because these assumptions are problematic, rigour requires that they be subjected to sustained critical scrutiny, as an integral part of science itself. Popper’s principle of demarcation must be rejected. Metaphysics and philosophy of science become a vital part of science. Natural philosophy is reborn. A solution to the problem of what it means to say a theory is unified is proposed, a problem Popper failed to solve. In The Logic of Scientific Discovery, Popper made important contributions to the interpretation of quantum theory, especially in connection with Heisenberg's uncertainty relations. Popper's advocacy of natural philosophy has important implications for education. (shrink)

This work is a study of Plato's ethical theory and in particular his paradoxical theses that virtue is knowledge and vice is ignorance and that no one voluntarily does evil. In the opening chapters O'Brien discusses Plato's debt to Homer and Hesiod and to the historians and tragedians. The succeeding chapters are devoted to an analysis of the ethical doctrines of over a dozen dialogues ranging from the Apology to the Laws. The principles of interpretation employed in the analysis are: (...) 1) each doctrine must be understood in relation to every other as well as to the whole, 2) we must give a literary analysis of the dialogues in addition to a textual and philosophical one, since Plato often prefers to suggest his view through his literary art rather than give them explicit statement, and 3) statements must be interpreted in context. From an application of these principles, Professor O'Brien concludes that Plato's ethical theory constitutes a unified set of doctrines. Elements which are often thought to be antithetic, i.e., the Socratic paradoxes and the partition of the soul, are seen to be complementary. The one affirms the rational unity of human nature and action and the other, the irrational multiplicity of both. In his words, they affirm "... virtue is knowledge, and it is more than knowledge." The book contains a long bibliography and an extensive index of topics discussed and texts cited. As a result, O'Brien's view on nearly every topic and text is readily accessible.—O. J. L. (shrink)

continent. 1.3 (2011): 149-155. The world is teeming. Anything can happen. John Cage, “Silence” 1 Autonomy means that although something is part of something else, or related to it in some way, it has its own “law” or “tendency” (Greek, nomos ). In their book on life sciences, Medawar and Medawar state, “Organs and tissues…are composed of cells which…have a high measure of autonomy.”2 Autonomy also has ethical and political valences. De Grazia writes, “In Kant's enormously influential moral philosophy, (...) autonomy , or freedom from the causal determinism of nature, became prominent in justifying the human use of animals.”3 One of the oldest uses of autonomy in English is a description of the French civil war from the late sixteenth century: “Others of the…rebellion entred in counsell, whether they ought to admit the King vpon reasonable conditions, specially hauing their autonomy.”4 Life, and in particular human life, and in particular human politics, is well served by the usages of autonomy . What about the rest of reality, however? Should it be thought of, if it's even considered real and mind-independent, as pure stuff for the manipulation or decorative tastes of truly autonomous beings? We tend to think of things such as paperweights and iPhones as mere tools of human design and human use. To use them is to cause them to exist as fully and properly as they can. But according to Martin Heidegger, when a tool such as a paperweight is used, it disappears, or withdraws ( Entzug ). We are preoccupied with copying the page that the paperweight is holding down. We are concerned with an essay deadline, and the paperweight simply disappears into this general project. If the paperweight slips, or if the iPhone freezes, we might notice it. All of a sudden it becomes vorhanden (present-at-hand) rather than zuhanden (ready-to-hand).5 Yet Heidegger is unable to draw a meaningful distinction between what happens to a paperweight when it slips from the book I'm copying from and what happens to the paperweight when it presses on the still resilient pages of the thick paperback itself. Further still and related to this point, even when I am using the paperweight as part of some general task, I am not using the entirety of the paperweight as such. My project itself selects a thin slice of paperweight-being for the purposes of holding down a book. Even when it is zuhanden the paperweight is withdrawn. Graham Harman is the architect of this way of thinking.6 Harman discovered a gigantic coral reef of withdrawn entities beneath the Heideggerian submarine of Da-sein, which itself is operating at an ontological depth way below the choppy surface of philosophy, beset by the winds of epistemology, and infested with the sharks of materialism, idealism, empiricism and most of the other isms that have defined what is and what isn't for the last several hundred years. At a moment when the term ontology was left alone like a piece of well chewed old chewing gum that no one wants to have anything to do with, object-oriented ontology (OOO) has put it back on the table. The coral reef isn't going anywhere and once you have discovered it, you can't un-discover it. And it seems to be teeming with strange facts. The first fact is that the entities in the reef—we call them “objects” somewhat provocatively—constitute all there is: from doughnuts to dogfish to the Dog Star to Dobermans to Snoop Dogg. People, plastic clothes pegs, piranhas and particles are all objects. And they are all pretty much the same, at this depth. There is not much of a distinction between life and non-life (as there isn't in contemporary life science). And there is not much of a distinction between intelligence and non-intelligence (as there is in contemporary artificial intelligence theory). A lot of these distinctions are made by humans, for humans (anthropocentrism). And the concept autonomy has come into play in policing such distinctions. In this essay I shall to try to liberate autonomy for the sake of nonhumans. I shall do so by parsing carefully the title, which is taken from Hakim Bey's work The Temporary Autonomous Zone .8 First we shall explore the term autonomous . Then we shall explore what the full meaning of zone is. Finally, we shall investigate what temporary means. Each of these terms is of great value. An object withdraws from access. This means that its very own parts can't access it. Since an object's parts can't fully express the object, the object is not reducible to its parts. OOO is anti-reductionist. But OOO is also anti-holist. An object can't be reduced to its “whole” either, “reduced upwards” as it were. The whole is not greater than the sum of its parts. So we have a strange irreductionist situation in which an object is reducible neither to its parts nor to its whole. A coral reef is made of coral, fish, seaweed, plankton and so on. But one of these things on its own doesn't embody part of a reef. Yet the reef just is an assemblage of these particular parts. You can't find a coral reef in a parking lot. In this way, the vibrant realness of a reef is kept safe both from its parts and from its whole. Moreover, the reef is safe from being mistaken for a parking lot. Objects can't be reduced to tiny Lego bricks such as atoms that can be reused in other things. Nor can be reduced upwards into instantiations of a global process. A coral reef is an expression of the biosphere or of evolution, yes; but so is this sentence, and we ought to be able to distinguish between coral reefs and sentences in English. The preceding facts go under the heading of undermining . Any attempt to undermine an object—in thought, or with a gun, or with heat, or with the ravages of time or global warming—will not get at the withdrawn essence of the object. By essence is meant something very different from essentialism . This is because essentialism depends upon some aspect of an object that OOO holds to be a mere appearance of that object, an appearance-for some object. This reduction to appearance holds even if that object for which the appearance occurs is the object itself! Even a coral reef can't grasp its essential coral reefness. In essentialism, a superficial appearance is taken for the essence of a thing, or of things in general. In thinking essentialism we may be able to discern another way of avoiding OOO. This is what Harman has christened overmining .? The overminer decides that some things are more real than others: say for example human perception. Then the overminer decides that other things are only granted realness status by somehow coming into the purview of the more real entity. When I measure a photon, when I see a coral reef, it becomes what it is. But when I measure a photon, I never measure the actual photon. Indeed, since at the quantum scale to measure means “to hit with a photon or an electron beam” (or whatever), measurement, perception ( aisthesis ), and doing become the same. What I “see” are deflections, tracks in a diffusion cloud chamber or interference patterns. Far from underwriting a world of pure illusion where the mind is king, quantum theory is one of the very first truly rigorous realisms, thinking its objects as irreducibly resistant to full comprehension, by anything.9 So far we have made objects safe from being swallowed up by larger objects and broken down into smaller objects—undermining. And so far we have made objects safe from being mere projections or reflections of some supervenient entity—overmining. That's quite a degree of autonomy. Everything in the coral reef, from the fish to a single coral lifeform to a tiny plankton, is autonomous. But so is the coral reef itself. So are the heads of the coral, a community of tiny polyps. So is each individual head. Each object is like one of Leibniz's monads, in that each one contains a potentially infinite regress of other objects; and around each object, there is a potentially infinite progress of objects, as numerous multiverse theories are now also arguing. But the infinity, the uncountability, is more radical than Leibniz, since there is nothing stopping a group of objects from being an object, just as a coral reef is something like a society of corals. Each object is “a little world made cunningly” (John Donne).10 We are indeed approaching something like the political valance of autonomy . The existence of an object is irreducibly a matter of coexistence. Objects contain other objects, and are contained “in” other objects. Let us, however, explore further the ramifications of the autonomy of objects. We will see that this mereological approach (based on the study of parts) only gets at part of the astonishing autonomy of things. Yet there are some more things to be said about mereology before we move on. Consider the fact that since objects can't be undermined or overmined, it means that there is strictly no bottom object . There is no object to which all other objects can be reduced, so that we can say everything we want to say about them, hypothetically at least, based on the behavior of the bottom object. The idea that we could is roughly E.O Wilson's theory of consilience .11 Likewise, there is no object from which all things can be produced, no top object . Objects are not emanations from some primordial One or from a prime mover. There might be a god, or gods. Suppose there were. In an OOO universe even a god would not know the essential ins and outs of a piece of coral. Unlike even some forms of atheism, the existence of god (or nonexistence) doesn't matter very much for OOO. If you really want to be an atheist, you might consider giving OOO a spin. If there is no top object and no bottom object, neither is there a middle object . That is, there is no such thing as a space, or time, “in” which objects float. There is no environment distinct from objects. There is no Nature (I capitalize the word to reinforce a sense of its deceptive artificiality). There is no world, if by world we mean a kind of “rope” that connects things together.12 All such connections must be emergent properties of objects themselves. And this of course is well in line with post-Einsteinian physics, in which spacetime just is the product of objects, and which may even be an emergent property of a certain scale of object larger than 10?¹?cm).13 Objects don't sit in a box of space or time. It's the other way around: space and time emanate from objects. How does this happen? OOO tries to produce an explanation from objects themselves. Indeed, the ideal situation would be to rely on just one single object. Otherwise we are stuck with a reality in which objects require other entities to function, which would result in some kind of undermining or overmining. We shall see that we have all the fuel we need “inside” one object to have time and space, and even causality. We shall discover that rather than being some kind of machinery or operating system that underlies objects, causality itself is a phenomenon that floats ontologically “in front of” them. In so doing, we will move from the notion of autonomy and begin approaching a full exploration of the notion of zone , which was promised at the outset of this essay. Since an object is withdrawn, even “from itself,” it is a self-contradictory being. It is itself and not-itself, or in a slightly more expanded version, there is a rift between essence and appearance within an object (as well as “between” them). This rift can't be the same as the clichéd split between substance and accidents , which is the default ontology. On this view, things are like somewhat boring cupcakes with somewhat less boring sugar sprinkles on them of different colors and shapes. But on the OOO view, what is called substance is just another limited slice of an object, a way of apprehending something that is ontologically fathoms deeper. What is called substance and what is called accidence are just on the side of what this essay calls appearance. The rift (Greek, chorismos ) between essence and appearance means that an object presents us with something like what in logic is known as the Liar: some version of the sentence “This sentence is false.” The sentence is true, which means that it is a lie, which means that it is false. Or the sentence is false, which means that it is telling the truth, which means that it is true. Now logic since Aristotle has tried desperately to quarantine such beasts in small backwaters and side streets so that they don't act too provocatively.14 But if OOO holds, then at least one very significant thing in the universe is both itself and not-itself: the object. An object is p ? ¬p. To cope with this fact, we shall need some kind of paraconsistent or even fully dialetheic logic, one that is not allergic to dialetheias (double-truthed things). Yet if we accept that objects are dialetheic, p ? ¬p, we can derive all kinds of things easily from objects. Consider the fact of motion. If objects only occupy one location “in” space at any “one” time, then Zeno's paradoxes will apply to trying to think how an object moves. Yet motion seems like a basic, simple fact of our world. Either everything is just an illusion and nothing really moves at all (Parmenides). Or objects are here and not-here “at the same time.”15 This latter possibility provides the basic setup for all the motion we could wish for. Objects are not “in” time and space. Rather, they “time” (a verb) and “space.” They produce time and space. It would be better to think these verbs as intransitive rather than transitive, in the manner of dance or revolt . They emanate from objects, yet they are not the object. “How can we know the dancer from the dance?” (Yeats).16 The point being, that for there to be a question, there must be a distinction—or there must not be (p ? ¬p).17 It becomes impossible to tell: “What constitutes pretense is that, in the end, you don't know whether it's pretense or not.”18 In this notion of the emergence of time and space from an object we can begin to understand the term zone . Zone can mean belt , something that winds around something else. We talk of temperate zones and war zones. A zone is a place where a certain action is taking place: the zone winds around, it radiates heat, bullets fly, armies are defeated. To speak of an autonomous zone is to speak of a place that a certain political act has carved out of some other entity. Cynically, Tibet is called TAR, the Tibetan Autonomous Region, for this very reason. In this phrase, Region tries to emulate zone : it sounds as if the place has its own rules, but of course, it is very much under the control of China. What action is taking place? “[N]ot something that just is what it is, here and now, without mystery, but something like a quest…a tone on its way calling forth echoes and responses…water seeking its liquidity in the sunlight rippling across the cypresses in the back of the garden.”19 If as suggested earlier there is no functional difference between substance and accidence; if there is no difference between perceiving and doing; if there is no real difference between sentience and non-sentience—then causality itself is a strange, ultimately nonlocal aesthetic phenomenon. A phenomenon, moreover, that emanates from objects themselves, wavering in front of them like the astonishingly beautiful real illusion conjured in this quotation of Alphonso Lingis. Lingis's sentence does what it says, casting a compelling, mysterious spell, the spell of causality, like a demonic force field. A real illusion: if we knew it was an illusion, if it were just an illusion, it would cease to waver. It would not be an illusion at all. We would be in the real of noncontradiction. Since it is like an illusion, we can never be sure: “What constitutes pretense…” A zone is what Lingis calls a level . A zone is not entirely a matter of “free will”: this concept has already beaten down most objects into abject submission. Objects are far more threateningly autonomous, and sensually autonomous, than the Kantian version of autonomy cited in the first paragraph of this essay. A zone is not studiously decided upon by an earnest committee before it goes into action. One of its predominant features is that it is already happening . We find ourselves in it, all of a sudden, in the late afternoon as the shadows lengthen around a city square, giving rise to an uncanny sensation of having been here before. Objects emit zones. Wherever I find myself a zone is already happening, an autonomous zone. It is the nonautonomous zones that are impositions on what is already the case. Or rather, these zones are autonomous zones that exclude and police. They are brittle. Every object is autonomous, but some objects try to maintain themselves through rigidity and brittleness, like (and such as) a police state. Paradoxically, the more rigidly one tries to exclude contradiction, the more virulent become the dialetheias that are possible. I can get around “This sentence is false” by imagining that there are metalanguages that explain what counts as a sentence. Then I can decide that this isn't a real sentence. This is basically Alfred Tarski's strategy, since he invented the notion of metalanguage specifically to cope with dialetheias.20 For example we might claim that sentences such as “This sentence is false” are neither true nor false. But then you can imagine a strengthened version of the Liar such as: “This sentence is not true”; or “This sentence is neither true nor false.” And we can go on adding to the strengthened Liar if the counter-attack tries to build immunity by specifying some fourth thing that a sentence can be besides true, false, and neither true nor false: “This sentence is false, or neither true nor false, or the fourth thing.” And so on.21 It seems as if language becomes more brittle the more it tries to police the Liars of this world. Why? I believe that this increasing brittleness is a symptom of a deep fact about reality. What is this deep fact? Simply that there are objects, that these objects are withdrawn, and that they are walking contradictions. This means indeed that (as Lacan put it) “there is no metalanguage,” since a metalanguage would function as a “middle object” that gave coherency and evenness to the others.22 Since there is no metalanguage, there is no rising above the disturbing illusory play of causality. This may even have political implications: no global critique is therefore possible, and attempts to smooth out or totalize are doomed to fail. To think the zone is to think the notion of temporary , which we shall now begin to discuss in greater detail. The zone is not in time: rather it “times.” But because a zone is an emanation of an object, it is based on a wavering fragility, since objects are p ? ¬p. When an object is born, that means that it has broken free of some other object. An object can be born because it and other objects are fragile. If not, no movement would be possible. Objects contain the seeds of their own destruction, a dialetheic sentence that says something like “This sentence cannot be proved.” Kurt Gödel argues that every true system of propositions contains at least one sentence that the system cannot prove. In order to be true, the system must have a minimum incoherence. To be real, it has to be fragile. Imagine a record player. Now imagine a record called I Cannot Be Played on This Record Player . When you play it on this record player, it produces sympathetic vibrations that cause the record player to shudder apart. No matter how many defense mechanisms you build in, there will always be the possibility of at least one record that destroys the record player.23 That is what being physical is. An object is inherently fragile because it is both itself and not-itself. When the rift between appearance and essence collapses, that is called destruction, ending, death. When an object breaks, several new objects are born. An opera singer sings a loud note in tune with the resonant frequency of a wine glass. (See the movie included below.) The singing is a zone, an autonomous level of intensity, opening a rift between appearance and essence. The glass ripples—for a moment it is nakedly a glass and a not-glass—almost as if it were having an orgasm, a little death. It is caught in the rift of the singing. Then its structure can't handle the coherence of the sound waves, and it breaks. It is incoherence and inconsistency that is the mark of existence, not consistency and noncontradiction. When things break or die, they become coherent. Essence disappears into appearance. I become the memories of friends. A glass becomes a dancing wave. Instantly, there are glass fragments, new temporary autonomous zones. The fragments have broken free from the glass. They are no longer its parts, but emanate their own time and space, becoming perhaps accidental weapons as they bury themselves in my flesh. Thus Hakim Bey's instructions on creating temporary autonomous zones oscillate disturbingly between performance art and politics, circus clowning and revolution. To play with the aesthetic is to play with causality, to rip from the sensual ether emanating from things new regions, new zones. Anarchist politics is the creation of fresh objects in a reality without a top or a bottom object, or for that matter a middle object: Everything in nature is perfectly real including consciousness, there's absolutely nothing to worry about. Not only have the chains of the Law been broken, they never existed; demons never guarded the stars, the Empire never got started, Eros never grew a beard. … There is no becoming, no revolution, no struggle, no path; already you're the monarch of your own skin—your inviolable freedom waits to be completed only by the love of other monarchs: a politics of dream, urgent as the blueness of sky.24 Bey imagines that this is because chaos is a primordial “undifferentiated oneness-of-being.” A Parmenides or a Spinoza or a Laruelle would read this a certain way. Individual objects, or decisions to talk about this rather than that, are just maggot-like things crawling around on the surface of the giant cheese of oneness.25 Yet he also describes chaos as “Primordial uncarved block, sole worshipful monster, inert & spontaneous, more ultraviolet than any mythology.” This image is of an inconsistent object, not of an undifferentiated field. An object, indeed, that can be distinguished from other things. If not, then the first part of The Temporary Autonomous Zone , subtitled “The Broadsheets of Ontological Anarchism,” is a kind of onto-theology. Onto-theology proclaims that some things are more real than others. Bey, however, is writing poetically, and thus ambiguously. We are at liberty to read “undifferentiated oneness-of-being” as something like the irreducibility of a thing to its parts and so forth (undermining and overmining). This certainly seems closer to the language in the following paragraph: “There is no becoming … already you're the monarch of your own skin.”26 On this view, there is no difference between art and politics: “When ugliness, poor design & stupid waste are forced upon you, turn Luddite, throw your shoe in the works, retaliate.” Since Romanticism this has been the war cry of the vanguard artist.27 To say to is to fall prey to the tired axioms of the avant-garde, and we think we know how the game goes. But OOO is not simply a way to advocate “new and improved” versions of this shock-the-bourgeoisie boredom. Bey's text is certainly full enough of that. Rather, since causality as such is aesthetic, and since nonhumans are not that different from humans, the new approach would be to form aesthetic–causal alliances with nonhumans. These alliances would have to resist becoming brittle, whether that brittleness is right wing (authoritarianism) or left wing (the endless maze of critique). No “ism,” especially not the ultimate forms, nihilism and cynicism, is in any sense effective at this point. All forms of brittleness are based on the mistaken assumption that there is a metalanguage and that therefore “Anything you can do, I can do meta.” I will not be listing any approaches here, as Bey does. Such lists and manifestos belong to the vanguardism that no longer works. Why? Not because of some marvelous revolution in human consciousness, but because nonhumans have so successfully impinged upon human social, psychic and aesthetic space. It is the time after the end of the world. That happened in 1945, when a thin layer of radioactive materials was deposited in Earth's crust. Geology now calls it this era the Anthropocene . Ironically, this period, named after humans, is the moment at which even the most thick headed of us make decisive contact with nonhumans, from mercury in our blood to manta rays to magnesium. Richard Dawkins, Pat Robertson and Lady Gaga all have to deal with global warming and mass extinction, somehow. We now live in an Age of Asymmetry marked by a skewed, spiraling relationship between vast knowledge and vast nonhuman things—both become vaster and vaster because of one another and for the same reasons.28 This means that coming up with the perfect attitude or the perfect aesthetic prescription just won't work any more. Even the most hardened anthropocentrist now has to pay through the nose for basic food supplies, and has to use more sunscreen. Whether he knows it or acknowledges it, he is already acting with regard towards nonhumans. There is nothing special to think, no special critique that will get rid of the stains of coexistence. The problem won't fit into the well-established modern boxes, which is why the “mystical,” “spiritual” quality of Bey's prose is welcome. Of course, when I put it this way, you may immediately close off and decide that I am talking about perfect attitudes after all, or something outside of politics, or other ways that the radical left marshals to police its thinking of the nonhuman. Because that is what is really at stake in all this: the nonhuman in its coexistence with the human—bosons, gods, clouds, spirits, lifeforms, experiences, the sunlight rippling across the cypresses. Bey begins to get at this in a Latour litany in the second part of The Temporary Autonomous Zone , “The Assassins”: Pomegranate, mulberry, persimmon, the erotic melancholy of cypresses, membrane-pink shirazi roses, braziers of meccan aloes & benzoin, stiff shafts of ottoman tulips, carpets spread like make-believe gardens on actual lawns—a pavilion set with a mosaic of calligrammes—a willow, a stream with watercress—a fountain crystalled underneath with geometry— the metaphysical scandal of bathing odalisques, of wet brown cupbearers hide-&-seeking in the foliage—“water, greenery, beautiful faces.”29 This will be conveniently dismissed as orientalism. If we're never allowed to escape the crumbling prison of modernity for fear of imperialism there is truly no hope. In a similar way, the fear of anthropocentrism and anthropomorphism is very often staged from a place that just is anthropocentrism .30 Critique turns into ressentiment . An object radiates a zone that is aesthetic and therefore causal. Because objects “time” they are temporary. Not because they exist “in” time that eventually gets the better of them. Their very existence implies the possibility of their non-existence. Since objects are not consistent, they can cease to exist. But nothing, no one, will ever be able to insert a blade between appearance and existence, even thought there is a rift there. Now that's what I call autonomy. NOTES 1.

In ancient philosophy, there is no discipline called “logic” in the contemporary sense of “the study of formally valid arguments.” Rather, once a subfield of philosophy comes to be called “logic,” namely in Hellenistic philosophy, the field includes (among other things) epistemology, normative epistemology, philosophy of language, the theory of truth, and what we call logic today. This entry aims to examine ancient theorizing that makes contact with the contemporary conception. Thus, we will here emphasize the theories of the “syllogism” (...) in the Aristotelian and Stoic traditions. However, because the context in which these theories were developed and discussed were deeply epistemological in nature, we will also include references to the areas of epistemological theorizing that bear directly on theories of the syllogism, particularly concerning “demonstration.” Similarly, we will include literature that discusses the principles governing logic and the components that make up arguments, which are topics that might now fall under the headings of philosophy of logic or non-classical logic. This includes discussions of problems and paradoxes that connect to contemporary logic and which historically spurred developments of logical method. For example, there is great interest among ancient philosophers in the question of whether all statements have truth-values. Relevant themes here include future contingents, paradoxes of vagueness, and semantic paradoxes like the liar. We also include discussion of the paradoxes of the infinite for similar reasons, since solutions have introduced sophisticated tools of logical analysis and there are a range of related, modern philosophical concerns about the application of some logical principles in infinite domains. Our criterion excludes, however, many of the themes that Hellenistic philosophers consider part of logic, in particular, it excludes epistemology and metaphysical questions about truth. Ancient philosophers do not write treatises “On Logic,” where the topic would be what today counts as logic. Instead, arguments and theories that count as “logic” by our criterion are found in a wide range of texts. For the most part, our entry follows chronology, tracing ancient logic from its beginnings to Late Antiquity. However, some themes are discussed in several eras of ancient logic; ancient logicians engage closely with each other’s views. Accordingly, relevant publications address several authors and periods in conjunction. These contributions are listed in three thematic sections at the end of our entry. (shrink)

Aristotle’s solution to Zeno’s arrow paradox differs markedly from the so called at-at solution championed by Russell, which has become the orthodox view in contemporary philosophy. The latter supposes that motion consists in simply being at different places at different times. It can boast parsimony because it eliminates velocity from the ontology. Aristotle, by contrast, solves the paradox by denying that the flight of the arrow is composed of instants; rather, on my reading, he holds that the flight is a (...) unity which is ontologically prior to the temporal parts that may be abstracted from it. I label this position temporal holism; and an entity that is ontological prior to its temporal parts lasting. Lasting, I argue, is the key to Aristotle’s solution to the arrow paradox, but it has received insufficient attention in the relevant literature. I therefore set out here to investigate lasting and highlight its major role in Aristotle’s metaphysics more broadly, and in his solution to other problems of change. I show, too, how lasting within a contemporary context underwrites a parsimonious and intuitive solution to the arrow paradox that retains instantaneous velocity, and hence solves a problem for those who think velocity is required within the ontology to underwrite certain causal roles.

The relationship between science and philosophy is contentious. Quine saw philosophy as continuous with science (broadly understood), but many philosophers see a dichotomy between them. The present paper discusses cases where the relevance of certain scientific findings has been denied (related to Zeno’s Dichotomy paradox and to the appeal of skeptical arguments) or overlooked (one argument related to the frame problem of artificial intelligence and Nagel’s “bat” argument). The results caution against overly quick dismissal of the import of science on (...) philosophical questions, whether the latter be of a more theoretical or practical nature. (shrink)

Zeno’s Paradoxes In the fifth century B.C.E., Zeno offered arguments that led to conclusions contradicting what we all know from our physical experience—that runners run, that arrows fly, and that there are many different things in the world. The arguments were paradoxes for the ancient Greek philosophers. Because many of the arguments turn crucially on … Continue reading Zeno’s Paradoxes →.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Natural Philosophy: On Retrieving a Lost Disciplinary Imaginary by Alister E. McGRATHJack ZupkoMcGRATH, Alister E. Natural Philosophy: On Retrieving a Lost Disciplinary Imaginary. Oxford: Oxford University Press, 2023. viii + 248 pp. Cloth, $39.95This book attempts to retrieve and reimagine the tradition of natural philosophy as an antidote for what the author sees as the fragmented, instrumentalized, and ethically disengaged understanding of the natural (...) world most of us have today. The idea is not to reinstate the older vision of Aristotle and Thomas Aquinas, with its final causes and animated spheres, or even the early modern culmination of natural philosophy in Newton’s universe of mathematically fixed natural laws; rather, the author hopes to engender a newer and deeper understanding of nature that is at once scientific, ethical, and poetic, which he explains in terms of the conceptual framework of Popper’s “Three Worlds”: objective, subjective, and theoretical. What is recovered thereby is said to be a “lost conceptual space” wherein human beings learn both about and from nature, modes of knowing rendered obsolete by disciplinary specialization in the sciences as well as our commitment to objective methods that leave no room for ethical or spiritual approaches to understanding the natural world and our place in it.The author covers quite a bit of ground on the historical side, from the ancient Greeks through the Middle Ages, moving on to the idea of natural philosophy as it was gradually transformed during the early modern period by Copernicus, Kepler, Galileo, Bacon, Boyle, and Newton—a picture finally eclipsed by the objective, empirical concept of natural science familiar to us today. Curiously, the book says very little about the Platonic tradition of natural philosophy that grew up around the Timaeus. Because it was available in Latin (or the first half of it, anyway, in a Latin translation by the Roman Neoplatonist Calcidius, who also wrote an influential commentary on the work), the Timaeus was, for almost a millennium, the authoritative text in natural philosophy in the West, at least until Aristotle’s nonlogical and scientific writings were recovered in the twelfth century. The Timaeus was the subject of many commentaries and philosophical discussions, from Calcidius in the fourth century to Bernardus Silvestris, William of Conches, and Alan of Lille in the twelfth. It fell out of favor among philosophers with the rise of Aristotle’s Physics and Aristotelian natural philosophy, though it continued to shape the popular imagination of nature in other genres, such as art and literature—recall, for example, the well-known image of “God the Geometer” (c. 1230), measuring the cosmos with a compass. If the author’s project is about “retrieving” natural philosophy “as a lost disciplinary imaginary” (the book’s subtitle), then surely the Platonic vision of the universe deserves equal billing with the Aristotelian. [End Page 158]That said, there is much to like in the project sketched here. The author’s diagnosis of the epistemic malaise of modern-day science sounds right to anyone familiar with the history of philosophy and natural science. So, even though we can now correctly describe the velocity constant of earth’s gravity as 9.8 m/s2, among other scientific achievements, we take ourselves to be wearing a different hat when we wax poetic at the beauty of the sky and the stars. Early-and pre-modern authors were more adept at bringing together science and poetry, but that might be because their epistemic position was radically different from our own. Calcidius, for example, finds it easy to draw moral and aesthetic conclusions from the motions of the cosmos because he really believed heavenly bodies are, like us, animated by souls. Even a materialist like Lucretius accepts that the gods exist; his (still) very radical thesis is that they don’t care about us. (And why should they? The Pythagorean theorem is much more beautiful and edifying to consider than the troubles of ignorant and weak-willed mortals.) Enlightened moderns that we are, we no longer believe the heavens are populated by super-intelligent beings; yet we continue to marvel at Van Gogh’s Starry Night and feel it is wrong to cause gratuitous...

To give an account of intentionality in terms of the concepts and methods of natural science has been considered as a crucial step towards a naturalization of mental phenomena in general, and as such it has been pursued by a large number of naturalist philosophers and cognitive scientists. Starting from the late 1960s the problem has been addressed in very different, reductionist and antireductionist ways . The development of these philosophical programs has benefited from the contemporary technical and theoretical (...) progresses of neuroscience, and leading scientists such as Changeux, Edelman and Damasio have presented articulated proposals of naturalization of intentionality . A common element of philosophical investigations turns out to be the reference to a still undeveloped neuroscientific theory. This reference belongs to the legacy of early XXth century anti-metaphysical “scientific philosophy”. In spite of this dominant philosophical approach, neuroscientists present their pioneering researches on intentionality with the help of metaphysical frameworks of the past, including Aristotelianism, materialism, emergentism and Spinozism. The final section of the paper examines this peculiar “paradox” of naturalization programs, by considering some critical exchanges about the neurobiological approach and by reviewing the role of metaphysical paradigms for different approaches to this issue.

The history of Natural Philosophy is dominated by a paradox; broadly speaking, a vast increase in its range of application to the external world has been accompanied by a sweeping simplification in its basic assumptions. From the standpoint of Empiricism this dual development appears utterly mysterious. On the other hand, Rationalism, which seeks to demonstrate the metaphysical necessity of natural law, and hence might throw light on this development, has been generally discredited, particularly by men of science. It (...) is not surprising, therefore, that philosophical discussion of scientific method has become a Babel of confusing tongues. (shrink)

More than sixty years after its first publication in Germany in 1935 by its then emigré author, and more than thirty-five years after its republication in Germany by an author who had returned via Italy, Japan, and the United States, Löwith’s classic study has finally been translated into English. His work thus joins that of Karl Jaspers and of his teacher, Martin Heidegger, all central interpretations of Nietzsche’s work written by his compatriots during the decade that witnessed the collapse which (...) his works so insistently and uncannily prophesied, if not encouraged. It is thus not merely an important interpretation, but itself part of our fast-closing century’s intellectual history. Löwith’s view of Nietzsche as the philosopher who undertakes “the anti-Christian repetition of antiquity on the peak of modernity” or who attempts to overcome nihilism by affirming an “eternally recurring existence amidst the naturelike world of all that is”, has in fact been accessible to readers before the translation of the present book. It figures prominently in From Hegel to Nietzsche, and in Meaning in History whose final section is entitled “Nietzsche’s Revival of the Doctrine of Eternal Recurrence.” Although the main lines of Löwith’s interpretation have not changed, there is no denying the value of having his detailed interpretation finally available to English readers. The work’s lengthy third chapter, “The Unifying Fundamental Idea in Nietzsche’s Philosophy,” is its indispensable core, detailing the eternal recurrence as the fundamental idea of Nietzsche’s philosophy through an analysis of Thus Spoke Zarathustra, and outlining two conflicting interpretations of this idea, the “anthropological”, with its focus on “willing the idea,” and the “cosmological”, where the idea reintegrates humanity into an ever-recurring world indifferent to its projects. The two chapters preceding it characterize Nietzsche’s philosophical discourse as a paradoxical “system in aphorisms” ; and present the familiar tripartite periodicization of Nietzsche’s philosophy, with Zarathustra as the apogee. The chapters that follow it do not have quite the unity or philosophical penetration of the first three. Chapter 4 concerns itself with the relation of Nietzsche’s rejection of Christianity to his affirmation of a Greek and specifically Heraclitean nature. Chapter 5 discusses the way in which the problems of history and fate and freedom and necessity are dealt with in some of Nietzsche’s early writings, laying the groundwork for the problem of “willing necessity” that seems present in the eternal recurrence. In the following chapter we are presented with a history of modern philosophy from Descartes to Marx as a history of the “loss of the world” by a humanity lost in the “desert of its freedom”. We are then offered, in the seventh chapter, a detailed analysis of Kierkegaard’s conception of “repetition” and Otto Weininger’s ethical conception of “recollection” as alternatives to Nietzsche’s conception of eternal recurrence. It is not at all clear that this last maintains its interest sixty years later, and the same doubt arises regarding several, though certainly not all of the books reviewed in his Appendix, “On the History of the Interpretation of Nietzsche ”. The work’s final chapter, “The Critical Yardstick for Nietzsche’s Experiments,” summarizes the significance of Nietzsche’s project as a “return to nature,” to the “physis of the world,” once the metaphysical God is gone as a support for any teaching about man. Löwith concedes that Nietzsche failed fully to separate himself from the Christianity that haunted him as a negation, but implies that his program, determined by the fact that “he decided against God and for the world”, is of enduring significance.

The author argues that, Although zeno's paradoxes on motion cannot be resolved in their own terms, They are nonetheless illegitimate. Examining the paradox of achilles and the tortoise, He finds that the mechanism of zeno's argument consists in an equivocal concept of motion characterized at once by a constant rate and by proportionate segments of movement. He then contends it is illegitimate to treat the concept of motion and its subconcepts like the postulates of a deductive system. However, That (...) the common theory of meaning presupposed by zeno's paradoxes is erroneous would have to be demonstrated metaphysically. (staff). (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 65.1 (2004) 1-13 [Access article in PDF] Ambiguities of the Prisca Sapientia in Late Renaissance Humanism Martin Mulsow University of Munich The wisdom of the ancients, says Marsilio Ficino, was a pious philosophy.1 Born among the Egyptians with Hermes Trismegistus—and, according to Ficino's later writings, concurrently among the Persians with Zoroaster—it was raised by the Thracians under Orpheus and Aglaophemus. It later matured (...) under Pythagoras among the Greeks and Italians and culminated in Plato. As is well known, this genealogy was not merely a historical thesis for Ficino and his followers but also a program for revival, a utopia achieved through restoration. For the assertion of a concordance between these early philosophies and their accordance with Christianity—in the sense of a Christian Platonism—implied the synthesis of fragementary philosophemes into a fully developed doctrine in the service of a uniform and timely philosophia pia.This program was formulated in a variety of ways during the sixteenth and seventeenth centuries with differing protagonists and with diverse aims. Thus one could supplement the genealogy in a cabalist vein, introduce biblical characters such as Solomon or Moses, or (as was done by Bruno) use it to contest Christian doctrine. The genealogy could be read as culminating in various notable modern figures such as for example, Paracelsus. Aristotle could be included or excluded from it, depending on whether one wanted to assimilate the Aristotelian tradition or to distance oneself from it; and one could leave the end [End Page 1] of this genealogical lineage open in order to exhort the necessity of a scientific and moral reform.Here, however, we shall be occupied with the question of what became of this program during the late Renaissance, when two developments took place simultaneously: on the one hand, the utopia of the prisca sapientia set about to conquer the field formerly reserved to the Aristotelians, namely, natural philosophy; on the other hand, the first doubts arose about the overall validity of the historical-philological foundation of the program, especially the dating of the works of Hermes Trismegistus. The latter began with the publication of the first part of Patrizi's Discussiones peripateticae in 1571,which aimed to rehabilitate, contrary to Aristotle's critique, old presocratic natural philosophies, and in so doing it cleared the way for interpreting the latest advancements in non-Aristotelian natural sciences as resumptions of these very philosophies.2 This initiated a period of complex interaction between late humanist philology, innovative natural science, and speculative metaphysics.This phase, however, not only entailed the grand synthesizing endeavors that one finds in Patrizi's Nova de universis philosophia;it also introduced historical critique—no doubt provoked by Patrizi—of the Hermetic prisca sapientia, understood in Frances Yates's sense, which was performed in careful detail long before Casaubon at the end of the Renaissance.3 Further, it was a phase characterized by an attempt to reevaluate Aristotelian philosophy against its opponents, which paradoxically was also motivated by Patrizi yet which managed to keep the venture open to "esoteric" depths. All of these developments were intertwined, and each effected the articulation of encyclopedic projects at the beginning of the seventeenth century. On the basis of manuscripts, letters, and some neglected texts, I want to introduce two such countercurrents, which illustrate how the migration of arguments from one cultural context to another can lead to wholly divergent and unexpected results. Moreover, these results show the diverse consequences that a prisca sapientia-utopia could have for different visions of encyclopedic scholarship.I. In the bookshop of Paolo Meietti in Padua, Teodoro Angelucci and Antonio Persio met accidentally on an autumn day in 1558. Meietti was the publisher of Angelucci's medical textbook as well as of texts by Patrizi and his [End Page 2] colleague Giannini, and it is possible that Persio was out to discuss publishing possibilities for his forthcoming manuscript De natura ignis. In any case, they were there for business-related matters, so it was quite natural for Persio to... (shrink)

A version of nonstandard analysis, Internal Set Theory, has been used to provide a resolution of Zeno's paradoxes of motion. This resolution is inadequate because the application of Internal Set Theory to the paradoxes requires a model of the world that is not in accordance with either experience or intuition. A model of standard mathematics in which the ordinary real numbers are defined in terms of rational intervals does provide a formalism for understanding the paradoxes. This model (...) suggests that in discussing motion, only intervals, rather than instants, of time are meaningful. The approach presented here reconciles resolutions of the paradoxes based on considering a finite number of acts with those based on analysis of the full infinite set Zeno seems to require. The paper concludes with a brief discussion of the classical and quantum mechanics of performing an infinite number of acts in a finite time. (shrink)

Cloth, $68.95.This is a peculiar book that depicts thirteenth-century natural philosophy as wholly dependent on the theological interests of the mendicant orders. For the Friars, “Natural (...) philosophy was a study in which the central concerns were the detection, admiration and appreciation of God’s existence, goodness, providence, munificence, forethought and provision for His creation” (4). Although conceived as “a positive contribution to the discipline of the history of science” (3), the work begins and ends with the claim that medieval natural philosophers were not engaged in science.One difficulty is that the authors never make clear what they mean by science, although they evidently understand that it entails a repudiation of metaphysics and a doctrine of nature’s radical autonomy. Consequently, for French and Cunningham medieval “science” is a mythic construct of modern historians, since “[t]here was no scientific tradition (in the modern sense of the term ‘scientific’) of looking at nature in the thirteenth century, only a religio-political way of doing so” (273).Thus, when summarizing the accomplishments of Roger Bacon, they note that “[Bacon] has been credited, along with Grosseteste, with creating early ‘experimental science’. Bacon could not of course have been a ‘scientist’ because he lived in the wrong [End Page 623] age for this” (238). This seemingly casual conclusion is rather stunning not only in its own right, but also as a revelation of the authors’ own effort to disenfranchise medieval ‘scientists’ for having had the misfortune of living too soon.French and Cunningham propose that polemical or apologetical interests urged the Friars to study nature as a response to various heretics and especially the Cathars who, seemingly like moderns, sought to disengage the natural world from the Christian God, while using the vocabulary of Aristotle’s libri naturales. However this central argument demands better support. Since the authors can cite only one surviving Cathar text—De duobus principiis (ca. 1230)—almost everything known of this group is derived from anti-Cathar polemics. Based on this single text the authors can say no more than that it used “what looks very much like a commentary on Aristotle’s Physics or Metaphysics,” (134) but fail to identify more precisely its sources. It is clear that thirteenth-century orthodox polemics increasingly relied on Aristotelian materials, but the conclusion that natural philosophers did so only in response to heretics who beat them to the Aristotelian punch seems tendentious. The historian will likely remain unconvinced that the unparalleled translating activity of the late eleventh and twelfth centuries—the rendering into Latin of Arabic scientific knowledge (as in Constantine the African’s Pantegni or Adelard of Bath’s Quaestiones naturales), Greek medical literature (e.g. Galen’s Methodus medendi translated by Gerard of Cremona and Burgundio of Pisa) and mathematics (e.g. Euclid’s Optics, Theodosius’s Spherics, Archimedes’ On the Quadrature of the Circle, and Ptolemy’s Tetrabiblos and Almagest) culminating with thirteenth-century translations of Aristotle’s biological works—should all have stemmed from a preoccupation with heresy.A further shortcoming of this book is the limited attention given to works on natural philosophy by the Friars themselves. The book’s first seven of eleven chapters explore the educational establishments in which natural philosophy arose: first monastic and cathedral schools, and then the universities. The works of individual Friars receive only the briefest summary. Among the Dominican natural philosophers Albertus Magnus—the patron saint of scientists and one of a very few scholastics to have commented on all of Aristotle’s biological works—is awarded only five pages. For his mastery of Aristotle’s libri naturales Albertus has been called “the dominant figure in Latin learning and natural science of the thirteenth century.” (Cf. Lynn Thorndike, History of Magic and Experimental Science [New York: Macmillan, 1929], 2:521) Albertus described not only the natural world but also explored the philosophical foundations for scientific knowledge. Yet curiously French and Cunningham give much more attention... (shrink)

This article argues that “philosophy” is a tradition which constantly redefines itself, and which, consequently, resists universal definition. Philosophy is, ultimately, whatever philosophers think it is. This discussion suggests that the most reasonable way of dealing with the vagueness of the term “Byzantine philosophy” is to focus on those Byzantine texts and authors which most closely relate to the concerns of other, more generally recognized, philosophical texts and authors. It starts by sketching a historical overview of Greek philosophy in (...) the Middle Ages and then presents some philosophical issues in logic, epistemology, metaphysics, and natural philosophy in which Byzantine philosophers engaged.

Of Zeno’s book of forty paradoxes, it was the first that attracted Socrates’ attention. This is the paradox of the like and the unlike. On contemporary assessments, this paradox is largely considered to be Zeno’s weakest surviving paradox. All of these assessments, however, rely heavily on reconstructions of the paradox. It is only relative to these reconstructions that there is nothing paradoxical involved, or that there is some rather obvious mistake being made. This paper puts forward and defends a (...) novel interpretation of this paradox, according to which the concept of a unit plays a central role. There is every reason to think the paradox turns on the concept of a unit: after the presentation of the paradox the text of the Parmenides immediately turns to a discussion of units, and the concept of a unit is also central to the Greek conception of a plurality. If this interpretation is correct then the paradox that Zeno presented was the same as one discussed and solved in Frege’s Grundlagen. (shrink)

Greek Natural Philosophy presents the primary sources on the Presocratics in a straightforward way in order to tell a coherent story about the astonishing development of natural philosophy in ancient Greece and its relevance today... Greek Natural Philosophy is suitable for undergraduate and graduate courses in ancient Greek philosophy or in environmental philosophy, and will be of interest to scholars in this field.

Zeno's extraordinary and disturbing paradoxes, the atomic theories of Democritus that so strikingly anticipate contemporary physics, the enigmatic and haunting epigrams of Heraclitus - these are just some of the riches to be found in this collection of writings of the early Greek philosophers. Jonathan Barnes's masterly Introduction shows how the most skilled detective work is often needed to reconstruct the ideas of these thinkers from the surviving fragments of their work. But the effort is always worth while. (...) In forging the first truly scientific vocabulary and offering rational arguments for their views, the pre-Socratics were doing something new and profoundly important; they also posed the questions that have remained at the centre of philosophy to this day.

This reflective work wants to disclose the intention moving early Greek philosophy, which, as the title hints, sought to lay bare the ground for "the way things are." The failure of the physiologoi to discover in nature an intelligible Gegenwart in which nature as a whole could appear led Heraclitus and Parmenides, to whom most of the book is devoted, to examine the ground of logos, and therewith, of truth and opinion. Commensurate with his intention to emphasize those elements (...) of early Greek philosophy common to its greatest representatives, Boeder concludes by pursuing his theme into Zeno's development of dialectic.--H.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 42.1 (2004) 101-103 [Access article in PDF] Cees Leijenhorst. The Mechanization of Aristotelianism: The Late Aristotelian Setting of Thomas Hobbes' Natural Philosophy. Leiden: Brill, 2002. Pp. xv + 242. Cloth, $97.00. Cees Leijenhorst, the young Dutch scholar and student of the late Karl Schuhmann, has written the most important book on Thomas Hobbes's natural science since Frithiof Brandt's Thomas Hobbes's Mechanical (...) Conception of Nature of 1928. This is true despite the undoubted brilliance and success of Leviathan and the Air Pump, published in 1985 by Simon Schaffer and Steven Shapin. Why this is so, it will be the burden of this review to clarify.Writing in the modern historiographical tradition known as contextualism, long associated with John Pocock, Quentin Skinner and Richard Tuck, Leijenhorst seeks to locate Hobbes within the horizon of that current of natural thought that began with Aristotle, led through antiquity and then flourished and came to predominate with the West's recovery of the Stagirite in the late Middle Ages. The course of so long a filiation of ideas cannot be the subject of a book whose length is under 250 pages, though a companion collection of essays on Aristotle and his long progeny, edited by Leijenhorst and others, has also appeared [End Page 101] (to be reviewed in the Journal). Instead, Leijenhorst focuses on the last, self-avowed inheritors and developers of that tradition, known as late Aristotelianism, though precisely how to define that tradition is itself problematized.Classically trained, Hobbes was well equipped to study Aristotle directly in Greek, without intermediaries; he early on published a translation of Thucydides. Still, Leijenhorst's concern is less to draw Hobbes closer to Aristotle than to relate him both to his immediate intellectual predecessors and to his own contemporaries, though, in each case, for different reasons. In the former, Leijenhorst convincingly argues that, as Gilson showed for Descartes, Hobbes assumed, drew upon, adopted and modified prevailing Aristotelian doctrines, even as he famously condemned their ancient author. And, Hobbes's sources, as they themselves interpreted, rejected and modified the views of their forebear, were rather various, including such writers of manuals as Bartholomaeus Anglicus and John Case, as well as others whose interests and directions were more varied and less conservative, including Scaliger, Rudolph Goclenius and Otto Casmann.A common source for both these strains of late Aristotelianism was the great stream of commentaries produced largely by members of the Jesuit Order from the middle of the sixteenth century onward, including Franciscus Toletus, Antonio Rubio, Petrus Fonseca, as well as Franciscus Suarez and members of other orders.This stream of thought also fed into the confessional strife of post-Reformation Europe, so that both Lutherans and Calvinists developed their own Aristotelianisms. One of the most striking conclusions of Leijenhorst's work is that, in characterizing both Aristotle's and his own metaphysics (or philosophia prima) as a universal science rather than as a particular theological science, Hobbes is an heir of this "Protestant ontology."Finally, Hobbes looked to the great names of natural-scientific thinking in sixteenth-century Italy, Zabarella, Pomponazzi, Fracastoro, Telesio and Campanella. Like Hobbes, these latter authors, "though vehemently anti-Aristotelian," nonetheless "exploited kinematic, empiricist and materialist tendencies found within the Aristotelian tradition itself, particularly in the School of Padua" (11).Such investigations into sources and lines of argument illuminate relations with predecessors and contemporaries in ways that social-constructivist accounts, like those of Schaeffer and Shapin and of the Edinburgh sociologist of knowledge David Bloor, may not accomplish. The author gives one instance of direct conflict between the results of that school and his own contextualism which illustrates this larger point.In his fight with Boyle, Hobbes is at pains to deny the existence of the void. Though he came to reject it rather late in his scientific thinking, the void, Schaffer and Shapin suggest, served to give space to the "incorporeal substances," similar to the scholastics' "abstract essences," upon which the latter erected the "kingdom of darkness" that...

First, I offer a short overview on the classical occidental philosophy as propounded by the ancient Greeks and the natural philosophies of the last 2000 years until the dawn of the empiricist logic of science in the twentieth century, which wanted to delimitate classical metaphysics from empirical sciences. In contrast to metaphysical concepts which didn’t reflect on the language with which they tried to explain the whole realm of entities empiricist logic of science initiated the end of metaphysical theories (...) by reflecting on the preconditions for foundation and justification of sentences about objects of investigation, i.e. a coherent definition of language in general, which was not the aim of classical metaphysics. Unexpectedly empiricist logic of science in the linguistic turn failed in the physical and mathematical reductionism of language and its use in communication, as will be discussed below in further detail. Nevertheless, such reflection on language and communication also introduced this vocabulary into biology. Manfred Eigen and bioinformatics, later on biolinguistics, used ‘language’ applied linguistic turn thinking to biology coherent to the logic of science and its formalisable aims. This changed significantly with the birth of biosemiotics and biohermeneutics. At the end of this introduction it will be outlined why and how all these approaches reproduced the deficiencies of the logic of science and why the biocommunicative approach avoids their abstractive fallacies.

MATHEMATICAL RESOLUTIONS OF ZENO’s PARADOXES of motion have been offered on a regular basis since the paradoxes were first formulated. In this paper I will argue that such mathematical “solutions” miss, and always will miss, the point of Zeno’s arguments. I do not think that any mathematical solution can provide the much sought after answers to any of the paradoxes of Zeno. In fact all mathematical attempts to resolve these paradoxes share a common feature, a feature (...) that makes them consistently miss the fundamental point which is Zeno’s concern for the one-many relation, or it would be better to say, lack of relation. This takes us back to the ancient dispute between the Eleatic school and the Pluralists. The first, following Parmenide’s teaching, claimed that only the One or identical can be thought and is therefore real, the second held that the Many of becoming is rational and real.1 I will show that these mathematical “solutions” do not actually touch Zeno’s argument and make no metaphysical contribution to the problem of understanding what is motion against immobility, or multiplicity against identity, which was Zeno’s challenge. I would like to point out at this stage that my contention. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Interpretation of Plato's Parmenides: Zeno s Paradox and the Theory of Forms R. E. ALLEN PLATO'S Parmenides is divided into three main parts, of uneven length, and distinguished from each other both by their subject matter and their speakers. In the first and briefest part (127d-130a), Socrates offers the Theory of Forms in solution of a problem raised by Zeno. In the second (130a-135d), Parmenides levels a series (...) of objections against Socrates' theory, objections putatively meant as refutation. Then, after an interlude to explain an unfamiliar method of dialectic (135d-137c), that method is applied in the third part by Parmenides, with the help of the young Aristoteles (137c-166c). This final part forms more than two-thirds of the whole. I propose here to examine the first part of the dialogue, the interchange between Zeno and Socrates, and to examine it with special attention to the bearing which questions of dialectical structure and dramatic characterization may have upon its interpretation. It is perhaps here proper to indicate the general view of the dialogue which this discussion will help serve to recommend. Briefly, it is this. The Parmenides is a sustained examination of Plato's Theory of Forms, and the manner of examination is Socratic: the student is presented, not with a body of conclusions, but with a series of arguments whose implications he is left to think through for himself. When he has done so, he will realize that the Theory of Forms is proof against the objections here brought against it: the Parmenides provides no direct support for the thesis, currently popular, that Plato in later life ceased to believe that Forms exist. But though sound as far as it goes, the Theory of Forms does not go far enough: the Parmenides demonstrates that there is a range of problems, bound up with the application of unrestricted predicates, which Forms do not solve but are prey to. A broader theory is required, though a theory which may well contain the Theory of Forms as a part. The Parmenides, whose purpose is critical, leaves unanswered the question of what that theory may be. Zeno's Paradox and the Theoryof Forms (127d-130a) It is Zeno who begins the dialectic of the Parmenides,and fittingly, he begins it with a paradox. If there are many things, the same things must be both [143] 144 HISTORY OF PHILOSOPHY like and unlike. But this is impossible: unlike things cannot be like, nor like things unlike. Therefore, there cannot be many things (127e). Socrates' reply begins with a solution, and ends with a challenge. There exists, alone by itself, a Form of Likeness, and also a Form of its opposite, Unlikeness. The things we call 'many' are both like and unlike; but in this they differ from the Forms in which they partake. For things which are just alike (abr& r& 6uoLa)1 cannot be unlike, nor things just unlike alike. But it is no more surprising that the same things should partake both in Likeness and Unlikeness than it is that a thing should be both one and many by partaking in both Unity and Plurality. Still, Unity itself is not many, nor Plurality one. And so with other Forms: Socrates would be filled with wonder if someone could show that Likeness and Unlikeness, Unity and Plurality, Rest and Motion, and the other Forms, can be combined with (~v'rK~p&vvwOaO and separated from (SLaKotp~0a,) each other. Forms cannot be qualified by their opposite. 2 Socrates' denial is a conjunction. Several translators, including Cornford and Taylor, have rendered ~v3,~p&vvvaOa~ ~as &aKps as though it were a disjunction, 'combined or separated'. The reason for this was no doubt stylistic; but the Greek means, not 'or' but 'and', and logically, the difference is important. Zeno and Parmenides are challenged to prove, not one of two alternatives, but both together. This conclusion rests on more than a Kas In the Sophist, knowing how to separate (&a~ps 253e 3) according to kinds is equivalent to distinguishing (&a~m~a0a~ 253d 1) according to kinds, and both are equivalent to not believing that the same Form is different or a different Form the same (253d 1...

Martin's undertaking is thus a re-examination of what it is that metaphysics is seeking, what the problem is which is basically at issue. He has chosen to do this through an analysis of the emergence of the metaphysical problem in Greek thought--coincidentally a very fine piece of scholarship in Greek philosophy--interpreting the fundamental Greek insights and their significance for present-day advance in metaphysical thought. Here I shall be able to touch on only some of the most important (...) points. (shrink)

"There are no paradoxes in mathematics," says Kurt Gödel. Moreover, Gödel seems to be right on this count. That is, there are no paradoxes, in the strict sense of the word, internal to the known and available body of mathematical knowledge. But while there are no paradoxes in mathematics, there certainly is an embarrassing bag of difficulties when we come to the application of mathematical concepts to the physical world. Of these, perhaps the most unruly offenders of (...) all are the problems proposed about 2500 years ago by Zeno and which, in modern idiom, have to do with the proper mathematical treatment of phenomena involving change and motion, and the physical meaning—if any—which may be assigned to convergent infinite series. At each stage in the growth of mathematical knowledge since their formulation Zeno's paradoxes have been the subject of some alleged resolution. Now Grünbaum contributes to this tradition, and it must be said that he makes a strong case. The weapons in the intellectual arsenal which Grünbaum brings to bear upon Zeno include such sophisticated devices as measure theory, but the weak link in the argument is in the first chapter where the author presents his somewhat psychologistic theory of temporal becoming. Grünbaum has a great many interesting things to say in later chapters about infinite processes, quantum mechanics, and Hilary Putnam. This is a first-rate contribution to the philosophy of physics.—H. P. K. (shrink)

"Through a close reading of rarely studied materials, the author examines the contested position of the body in Renaissance philosophy, showing how abstract metaphysical ideas evolved in tandem with the creation of new metaphors that shaped the understanding of early modern political, cultural, and scientific practices. The result is a new approach to the issues that describes the function of new technologies (such as optics and distillation) and their interaction with popular creeds (such as witchcraft and folk medicine), as well (...) as their relationship to the newly discovered ancient Greek and Roman texts that captured the attention of Renaissance intellectuals. The text also investigates, for the first time, how some philosophers forged their original syntheses from newly available and traditional materials. In so doing, these philosophers contributed in unexpected ways to the formation of new cultural practices--practices that entailed largely unexplored conceptualisations of physical bodies but also linked inextricably to the formation of new and striking metaphors for the physical world."--Publisher.

Aristotle asserts that philosophy, which begins in wonder, seeks principles and causes in the world, just as mythology does, but each in a different way. This article argues that Homer analyzes the world according to Vico’s imaginative genera; early Greek philosophy according to natural genera, and philosophers in the strict sense according to rational genera. Thus, Homer’s rainbow is the goddess Iris, which Xenophanes divides into natural object and divinity, and which Aristotle calls principles or causes. In (...) the transition from imaginative to natural genus, wonder is lost because the enchanted world of mythology has become explicable in terms of the five senses. Plato’s and Aristotle’s philosophical approach seeks to restore wonder without remythologizing the world. Homer’s Oceanus myth is examined, in relation to the testimony of Thales and the fragments of Xenophanes, and as reflected explicitly and implicitly in the works of Plato and Aristotle. (shrink)

One of the most peculiar features of Spinoza’s philosophy is his radical interpretation of the notion of freedom. Even though it plays a significant role in his metaethics and political philosophy, freedom is, for Spinoza, a deeply metaphysical notion, rooted in the most fundamental features of his ontology. In this paper, I analyze the internal structure that identifies a being as “free” within Spinoza’s metaphysics. I argue that this structure leads to an internal paradox, entailing that the very component that (...) allows a being its freedom – its essence or nature – is itself externally determined. I further proceed to resolve this issue indicating how Spinoza’s metaphysics of freedom can accommodate this paradox. I conclude by presenting possible solutions for both Natura naturans and Natura naturata, attempting to integrate the notion of metaphysical freedom with more familiar images of ethical and epistemological freedom.

As with so many mystics, Alexis karpouzos intuitively know the oneness of cosmic creation and historic humanity as part of all that is and all there isn't. So, the originality of Alexis Karpouzos thought is that it crosses the most diverse fields, the most opposing philosophies, to unite them into an often contradictory and broken whole. Marx and Heidegger, Nietzsche, Freud and Heraclitus, poets and political theorists all come together in the same distance and the same unusual proximity. Alexis karpouzos (...) use Pre-Socratics philosophy and generally the ancient Greek philosophy, as well as the pre-philosophical thinking of The Upanishads, the Vedas and Buddhism in India, of Lao Tzu, of Zen Buddhism and the Taoist tradition in China, of the Arab mystics and poets, with their metaphysical religiosity as the metaphysical basis for the interpretation and understanding of the world and existence. At the same time the ancient metaphysics is connect with Hegel’s dialectical ontology and with the modern thinking of Marx, Nietzsche, Freud, Heidegger, and others as the interpretive context for understanding the central problems of the technical and scientific world during his time. Novalis, Hölderlin, Rimbaud, Whitman, Eliot and others show the dreamy nature of existence, the transcendence of the Cosmos, welcome the infinity. For Alexis karpouzos the combination of ancient and modern thought creates the holistic experience of universal space-time and the consciousness of the unity. The poetic thought of Alexis karpouzos is a expressions of soul's inner experiences, expression of universality. The inspiring visual images and the symbolic use of language offer a description of elevating experiences of consciousness, a glimpse of higher worlds. The philosophy of Alexis karpouzos speak to the human experience from a universal perspective, transcending all religions, cultural and national boundaries. Using vivid images and a direct language that speaks to the heart, his philosophy evokes a sense of deep communication with the collective unconscious, a sense of connection to all the creatures of the world, compassion for others, admiration for the beauty of nature, reverence for all life, and an abiding faith in the invisible touch of world. Alexis karpouzos thoughts are often terse and paradoxical, challenging us to to break out of the box of limiting beliefs and see things from a new perspective. Above all, Alexis karpouzos continually calls to us to wake up and explore the mysteries within our own selves, i.e the mysteries of universe. (shrink)

The essays in this volume treat a wide variety of fundamental topics and problems in ancient Greek philosophy. The scope of the section on pre-Socratic thought ranges over the views which these thinkers have on such areas of concern as religion, natural philosophy and science, cosmic periods, the nature of elements, theory of names, the concept of plurality, and the philosophy of mind. The essays dealing with the Platonic dialogues examine with unusual care a great number of central (...) themes and discuss them in considerable depth: problems in language and logic, myth, reason, hypothesis, eros, friendship, reason, morality, society, art, the nature of soul, and immortality. In addition, they offer fresh discussions on a number of basic morphological, methodological, and philological issues related to philosophical arguments and introduce new aspects for a critical reexamination of controversies surrounding the doctrines and the authenticity of certain Platonic works. The essays on the philosophy of Aristotle are closely reasoned analyses of such basic themes as the universality of the sensible, the nature of kinesis, the problem of future contingencies, the meaning of qualitative change, the doctrine of phantasia, the essence of intelligence, and the metaphysical foundations for the ethical life. The essays on post-Aristotelian developments in ancient philosophy offer challenging and well-documented discussions on topics in the history of ancient logic, categorical thought, the ethical doctrines of ancient Scepticism, epistemological issues in the physical theory of the Epicureans, and basic concepts in the metaphysics of the neo-platonists.

Heraclitus accepts as a principle that any particular insight into things is necessarily partial and perspectival. Edward Halper has discussed how, for this reason, it is in principle impossible for a particular thinker to attain the perspective of the Logos by which the whole can be made intelligible. So, metaphysics itself tells us that metaphysics is impossible. According to Halper, Heraclitus was wrong to take the Logos as applying to itself, as the Logos should properly be understood as applying only (...) to what is not a product of human agency. I argue that Halper’s move cannot serve as a corrective patch to Heraclitus’ metaphysical thought, since it posits a distinction between the human and the rest of reality which Heraclitus could never accept. Although not a radical monist who denies the reality of all multiplicity, a fundamental principle of his thought is that all distinctions and oppositions are grounded in a more fundamental unity. I instead approach the Heraclitean paradox by appealing to the strategy, familiar from a number of ancient Greek philosophers, of making a distinction between different levels of knowledge inherent within the same knower.

This collection of original articles draws from a cross section of distinguished scholars of ancient Greek philosophy. It is focussed primarily on the philosophy of Aristotle but comprises as well studies of the philosophy of Socrates, Plato, and Epicurus. Its authors explore a range of complementary topics in value theory, moral psychology, metaphysics, natural philosophy, political theory, and methodology, highlighting the rich and lasting philosophical contributions of the thinkers investigated. Opening with an engaging intellectual autobiography of its honoree, (...) Fred D. Miller, Jr., the volume offers treatments of Socrates as a citizen; Plato’s attitude towards poetry; Socratic self-knowledge; Plato’s conception of law in his Republic; explorations of reason, goodness, and moral conduct in Plato; Platonic metaphysics; Aristotelian causation; Aristotelian metaphysics and normativity; natural philosophy in Aristotle; Aristotelian logic; political theory and approaches to justice in Aristotle’s Politics; methodological reflections on how best to approach Aristotle’s indefensible ideas; and closes with a reconsideration of Epicurus on death and the art of dying. Altogether, the volume reflects the richness of the ongoing community of philosophical scholars dedicated to reconstructing, assessing, and criticizing the principal philosophers of the ancient world, whose epoch-forming explorations of the key elements of human life—considered socially, politically, psychologically, and metaphysically—remain topics of lively investigation today. It will be of interest to philosophers of many stripes, including those with a primary interest in ancient philosophy but extending as well to those with systematic interests in the themes it explores. This volume will be a valuable addition to all libraries serving communities dedicated to researching and studying the origins of Western philosophy. (shrink)
