This article takes a cognitive approach to natural concepts. The aim is to introduce criteria that are evaluated with respect to how they support the cognitive economy of humans when using concepts in reasoning and communicating with them. I first present the theory of conceptual spaces as a tool for expressing the criteria. Then I introduce the central idea that natural concepts correspond to _convex_ regions of a conceptual space. I argue that this criterion has far-reaching consequences as (...) regards natural concepts. Partly following earlier work, I present some other criteria that further delimit the class of natural concepts. One of these is coherence, which does not seem to have been discussed previously. Finally, I show that convexity and other criteria make it possible to ensure that people mean the same thing when they communicate using concepts. Apart from its philosophical interest, the analysis presented in the article will be relevant for tasks of conceptual engineering in artificial systems that work with concepts. (shrink)

Conceptual spaces have become an increasingly popular modeling tool in cognitive psychology. The core idea of the conceptual spaces approach is that concepts can be represented as regions in similarity spaces. While it is generally acknowledged that not every region in such a space represents a natural concept, it is still an open question what distinguishes those regions that represent natural concepts from those that do not. The central claim of this paper is that natural concepts (...) are represented by the cells of an optimally designed similarity space. (shrink)

The conceivability argument against materialism, originally raised by Saul Kripke and then reformulated, among others, by David Chalmers holds that we can conceive of the distinctness of a phenomenal state and its neural realiser, or, in Chalmers’ variation of the argument, a zombie world. Here I argue that both phenomenal and natural kind terms are ambiguous between two senses, phenomenal and natural, and that the conceivability argument goes through only on one reading of a term. Thus, the antimaterialist (...) has to provide some reasons independent of anti-materialism itself to favour that reading of a term that supports his or her argument. Given that there are no such independent reasons, I conclude that we should put more weight on empirical considerations than on a priori discussion in resolving the question concerning the identity between a phenomenal state and its neural realiser.

According to a recent proposal, natural concepts are represented in an optimally designed similarity space, adhering to principles a skilled engineer would use for creatures with our perceptual and cognitive capacities. One key principle is that natural concepts should be easily learnable. While evidence exists for parts of this optimal design proposal, there has been no direct evidence linking naturalness to learning until now. This article presents results from a computational study on perceptual color space, demonstrating that naturalness (...) indeed facilitates learning. (shrink)

Continental philosophers such as Heidegger and Nicolai Hartmann and analytic philosophers such as Ryle, Strawson, and Jennifer Hornsby may be interpreted as using competing intellectual strategies within the framework of one and the same research programme, the programme of developing a natural conception of the world. They all argue that the Manifest Image of the world (to use Sellars's terminology) is compatible with, or even more fundamental than, the Scientific Image. A comparative examination of these strategies shows that Hartmann's (...) strategy of stratification is superior to those of Heidegger, Ryle, and Strawson. (shrink)

I analyze the two main theses of Helmholtz's "The Applicability of the Axioms to the Physical World," in which he argued that the axioms of Euclidean geometry are not, as his neo-Kantian opponents had argued, binding on any experience of the external world. This required two argumentative steps: 1) a new account of the structure of our representations which was consistent both with the experience of our (for him) Euclidean world and with experience of a non-Euclidean one, and 2) a (...) demonstration of why geometric propositions are essentially connected to material and temporal aspects of experience. The effect of Helmholtz's discussion is to throw into relief an intermediate category of metrological objects--objects which are required for the properly theoretical activity of doing physical science (in this sense, a priori requirements for doing science), all while being recognizably contingent aspects of experience.

The four experiments presented support Boyer's theory that counterintuitive concepts have transmission advantages that account for the commonness and ease of communicating many non-natural cultural concepts. In Experiment 1, 48 American college students recalled expectation-violating items from culturally unfamiliar folk stories better than more mundane items in the stories. In Experiment 2, 52 American college students in a modified serial reproduction task transmitted expectation-violating items in a written narrative more successfully than bizarre or common items. In Experiments 3 and (...) 4, these findings were replicated with orally presented and transmitted stimuli, and found to persist even after three months. To sum, concepts with single expectation-violating features were more successfully transmitted than concepts that were entirely congruent with category-level expectations, even if they were highly unusual or bizarre. This transmission advantage for counterintuitive concepts may explain, in part, why such concepts are so prevalent across cultures and so readily spread. (shrink)

This volume examines the notion of an analytic proof as a natural deduction, suggesting that the proof's value may be understood as its normal form--a concept with significant implications to proof-theoretic semantics.

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...

The framework of natural deduction is extended by permitting rules as assumptions which may be discharged in the course of a derivation. this leads to the concept of rules of higher levels and to a general schema for introduction and elimination rules for arbitrary n-ary sentential operators. with respect to this schema, (functional) completeness "or", "if..then" and absurdity is proved.

We are still looking for a satisfactory definition of what makes an individual being a human individual. The understanding of human beings in terms of organism does not seem to be satisfactory, because of its reductionistic flavor. It satisfies our need for autonomy and benefits our lives thanks to its medical applications, but it disappoints our needs for conscious and free, self-determination. For similar reasons, i.e. because of its anti-libertarian tone, an organicistic understanding of the relationship between individual and society (...) has also been rejected, although no truly satisfactory alternative for harmonizing individual and social wellness has been put forth. Thus, a reassessment of the very concepts of individual and organism is needed. In this book, the authors present a specific line of thought which started with Leibniz' concept of monad in 17th century, continued through Kant and Hegel, and as a result reached the first Eastern country to attempt to assimilate, as well as confront, with Western philosophy and sciences, i.e. Japan. The line of thought we are tracing has gone on to become one the main voices in current debates in the philosophy of biology, as well as philosophical anthropology, and social philosophy. As a whole, the volume offers a both historical, and systematic account of one specific understanding of individuals and their environment, which tries to put together its natural embedding, as well as its dialectical nature. Such a historical, systematic map will also allow to better evaluate how life sciences impact our view of our individual lives, of human activities, of institutions, politics, and, finally, of humankind in general.

Recent scholarship has gone a long way toward placing Locke in his intellectual and historical context, and thus in coming to see the respect in which his work has a previously unacknowledged conceptual unity. There remains, however, some difficulty in reconciling the style, purpose and content of his two major works. The Essay Concerning Human Understanding is usually read as primarily concerned with issues in epistemology and philosophy of science, while the Two Treatises of Government is regarded as less systematically (...) rigorous, or at worst ad hoc political analysis. These two sides of Locke thus remain virtually unrelated fields of specialization among interpreters. ;My dissertation is a contribution to the project of understanding Locke's work as a connected whole; without attributing to him an attitude of scientific reductionism, I argue that the account which Locke gives of personal property in the Second Treatise bears an important relation to his account of qualities and personal identity in the Essay. Specifically, I try to make plausible the claim that there is in Locke a direct analogy between the property of a human person, on one hand, and the properties of a natural substance on the other. I suggest that Locke's methodological atomism in science and epistemology parallels his qualifiedly individualistic political theory, and thus that his claims about private property can be understood in terms of a broader philosophical context than is usually supposed. ;As part of a larger project concerning the genealogy of the concept of property and the relation between metaphysics and morality, I expect this work to have useful implications regarding much of contemporary moral and political theory. Given the historical influence of Locke's political work, a careful analysis of it in terms of its epistemological and scientific grounding should contribute to a rethinking of much twentieth century work on property and justice.

The concepts to be considered in this chapter are those that occur in everyday common human thought and language – the “natural history” of concepts in use. While many may appear to be constituted by similarity relations, which make them suitable for modelling in conceptual spaces for example, other concepts in everyday use may be differently constituted. These concepts include abstract concepts, essentialist kinds, natural kinds, and logical or mathematical concepts. I discuss the different sources, uses and epistemological (...) bases of these different forms of concept, and propose a three-level hierarchy of concepts based on their sources of validation.

What is a natural kind? As we shall see, the concept of a natural kind has a long history. Many of the interesting doctrines can be detected in Aristotle, were revived by Locke and Leibniz, and have again become fashionable in recent years. Equally there has been agreement about certain paradigm examples: the kinds oak, stickleback and gold are natural kinds, and the kinds table, nation and banknote are not. Sadly agreement does not extend much further. (...) It is impossible to discover a single consistent doctrine in the literature, and different discussions focus on different doctrines without writers or readers being aware of the fact. In this paper I shall attempt to find a defensible distinction between natural and non-natural kinds. (shrink)

The Darwinian concept of natural selection was conceived within a set of Newtonian background assumptions about systems dynamics. Mendelian genetics at first did not sit well with the gradualist assumptions of the Darwinian theory. Eventually, however, Mendelism and Darwinism were fused by reformulating natural selection in statistical terms. This reflected a shift to a more probabilistic set of background assumptions based upon Boltzmannian systems dynamics. Recent developments in molecular genetics and paleontology have put pressure on Darwinism once (...) again. Current work on self-organizing systems may provide a stimulus not only for increased problem solving within the Darwinian tradition, especially with respect to origins of life, developmental genetics, phylogenetic pattern, and energy-flow ecology, but for deeper understanding of the very phenomenon of natural selection itself. Since self-organizational phenomena depend deeply on stochastic processes, self-organizational systems dynamics advance the probability revolution. In our view, natural selection is an emergent phenomenon of physical and chemical selection. These developments suggest that natural selection may be grounded in physical law more deeply than is allowed by advocates of the autonomy of biology, while still making it possible to deny, with autonomists, that evolutionary explanations can be modeled in terms of a deductive relationship between laws and cases. We explore the relationship between, chance, self-organization, and selection as sources of order in biological systems in order to make these points. (shrink)

The objective of this works in to analyze the conditions of transference of sovereignty and the concept of natural liberty in William of Ockham. Firstly, I briefly explain some antecedents of the conflict of ‘investidures’. Secondly, I will show that Ockham advanced the existence of a set of natural rights hold by the community. This permitted to argue against the Papal interference in the secular sphere, but also to set limits to the emperor himself and grant the (...) individual with natural rights. Thirdly, I explain the differences between ius fori and ius poli and I suggest that Ockham did not provide point of contact between these laws, excepting in the case of liberty. Finally, I revise briefly Ockham’s term translation imperii. (shrink)

Nagle, Cormac M Global warming has made us much more aware of the need to respect the physical laws of nature and make responsible decisions. This article examines the nature and role of the concept of natural law in guiding us to choose morally and wisely in face of the responsibilities and especially the conflicting values encountered in daily living.

Lockean accounts of personhood propose that an individual is a person just in case that individual is characterized by some advanced cognitive capacity. On these accounts, human beings with severe cognitive impairment are not persons. Some accept this result—I do not. In this paper, I therefore advance and defend an account of personhood that secures personhood for human beings who are cognitively impaired. On the account for which I argue, an individual is a person just in case that individual belongs (...) to a natural kind that is normally characterized by advanced cognitive capacities. Since “human being” is just such a natural kind, individual human beings can be persons even when they do not themselves have advanced cognitive capacities. I argue, furthermore, that we have good reason to accept this account of personhood over rival accounts since it is uniquely able to accommodate the intuitive concept of an impaired person. (shrink)

The rosy dawn of my title refers to that optimistic time when the logical concept of a natural kind originated in Victorian England. The scholastic twilight refers to the present state of affairs. I devote more space to dawn than twilight, because one basic problem was there from the start, and by now those origins have been forgotten. Philosophers have learned many things about classification from the tradition of natural kinds. But now it is in disarray and (...) is unlikely to be put back together again. My argument is less founded on objections to the numerous theories now in circulation, than on the sheer proliferation of incompatible views. There no longer exists what Bertrand Russell called ‘the doctrine of natural kinds’—one doctrine. Instead we have a slew of distinct analyses directed at unrelated projects. (shrink)

“Natural” and “law” form a particular symbol pertaining to one mode of discovering the order of goodness, this mode invented by the classical Greek philosophers. They relied on a number of basic experiences and symbolic concepts: a) the nous (mind, reason); something divine in man participating in the mind of divinity; b) the distinction between “being” as the immanent order of “things” and “being” as the divine transcendence; c) the realization that man, possessing language and moral discernment, has an (...) order not merely as a “thing” but also as a participating partner of the transcendence. In modern times these concepts and underlying experiences have been lost. “Mind” and “rationality” to us mean the opposite of what they meant to the Greek philosophers. We have no longer a concept of “man” resembling theirs; the concept of “soul” has disappeared; all values are completely relativized. We cannot, therefore, bring back “natural law” simply by reading the classical texts. The awareness of the order of goodness must be regained, but we have to pay a price for that. It probably requires the kind of deeply shaking experiences that came to members of Soviet labor camps as described by Solzhenitsyn and his friends. It also would include jettisoning our Enlightenment concept of history. Short of such sacrifices we would do well to use the concept “natural law” reluctantly, if at all. (shrink)

The present paper stems from the biosemiotic modelling of individual artificial cognition proposed by Ferreira and Caldas (2012) but goes further by introducing the concept of Umwelt Overlap. The introduction of this concept is of fundamental importance making the present model closer to natural cognition. In fact cognition can only be viewed as a purely individual phenomenon for analytical purposes. In nature it always involves the crisscrossing of the spheres of action of those sharing the same environmental (...) bubble. Plus, the incorporation of that concept is vital to understand the complex semiosis that sustains collective tissues, societies, regulating collective cognition and consequently cooperative action. The concept of Umwelt Overlap broadens the range of applicability of the previous model to several distinct domains allowing for example for its application to multi-agent cooperative autonomous systems. In this paper a Middle Size League RoboCup soccer team is used as an example of a possible application. (shrink)

The concept of intrinsic value has enjoyed a long, rich history. From the time of the ancient Greeks to the present day, philosophers have placed it at the foundation of much of their theorizing. This is especially true of G.E. Moore, who made it the cornerstone of his Principia Ethica. Yet this venerable concept has recently come under serious, sustained attack. My aim in this paper is to show that this attack has been unsuccessful.When Principia Ethica appeared, its (...) impact on the philosophical community was immediate and profound. Of course, much of what Moore had to say was, and continues to be, strongly disputed. The view that goodness is a simple nonnatural property has been criticized by many people and in many ways. Some have argued that goodness is an analyzable property. Others have argued that it is a natural property. Still others have argued, more radically, that goodness is not a property at all. But none of these critics has rejected the very idea of goodness. None of them, that is, has contended that to say of something that it is good is to speak nonsense. (shrink)

One of the central themes of inquiry for Karl Barth, the twentieth-century Protestant theologian, was the notion of revelation. Although he was suspicious of natural theology, recent scientific advances and the flourishing modern dialogue between science and religion offer compelling reasons to revisit Barth’s thinking on the concept. We must again ask whether and how it might be possible to hold together the notion of revelation whilst employing reason and scientific evidence in the justification of belief. In The (...) Heavens Declare, author Rodney Holder re-examines Barth’s natural theology argument and then explores how it has been critiqued and responded to by others, starting with Dietrich Bonhoeffer and Wolfhart Pannenberg. Holder then considers the contributions of two notable British participants in the science-religion dialogue, Thomas Torrance and Alister McGrath, who, despite their repudiation of natural theology in the traditional sense, also provide many positive lessons. The book concludes by defending an overall position which takes into account the ideas of the aforementioned theologians as well as others who are currently engaged positively in natural theology, such as John Polkinghorne and Richard Swinburne. Holder’s new study is sure to be of interest to theologians, philosophers of religion, and all scholars interested in the science-religion dialogue, especially those interested in natural theology as an enterprise in itself.

In biosemiotics, life and living phenomena are described by means of originally anthropomorphic semiotic concepts. This can be justified if we can show that living systems as self-maintaining far from equilibrium systems create and update some kind of representation about the conditions of their self-maintenance. The point of view is the one of semiotic realism where signs and representations are considered as real and objective natural phenomena without any reference to the specifically human interpreter. It is argued that the (...) most basic concept of representation must be forward looking and that both C. Peirce’s and J. v. Uexküll’s concepts of sign assume an unnecessarily complex semiotic agent. The simplest representative systems do not have phenomenal objects or Umwelten at all. Instead, the minimal concept of representation and the source of normativity that is needed in its interpretation can be based on M. Bickhard’s interactivism. The initial normativity or natural self-interest is based on the ‘utility-concept’ of function: anything that contributes to the maintenance of a far from equilibrium system is functional to that system — every self-maintaining far from equilibrium system has a minimal natural self-interest to serve that function, it is its existential precondition. Minimal interactive representation emerges when such systems become able to switch appropriately between two or more means ofmaintaining themselves. At the level of such representations, a potentiality to detect an error may develop although no objects of representation for the system are provided. Phenomenal objects emerge in systems that are more complex. If a system creates a set of ongoingly updated ’situation images’ and can detect temporal invariances in the updating process, these invariances constitute objects for the system itself. Within them, a representative system gets an Umwelt and becomes capable of experiencing triadic signs. The relation between representation and its object is either iconic or indexical at this level. Correspondingly as in Peirce’s semeiotic, symbolic signs appear as more developed — for the symbolic signs, a more complex system is needed. (shrink)

Science starts by using terms such as ‘temperature’ or ‘fish’ or ‘gene’ to preliminarily delimitate the extension of a phenomenon, and concludes by giving most of them a technical meaning based on an explanatory model. This transforma- tion of the meaning of the term is an essential part of its naturalization. Debating on the definition of ‘disease’, what most philosophers of medicine have examined is the pre-naturalized meaning of the term: for that reason they have focused on the task of (...) delimiting disease and non-disease (health), mainly used conceptual analysis as a method of choice, and considered the nosological level of ‘disease judgments’ rather than the pathophysiological or psychopathological level of disease mechanisms, thus making them impervious to most scientific discoveries. By focusing instead on the naturalized concept of disease and following some suggestions by philosophers of biology and scientists in cutting-edge fields of biomedical research, they could gar- ner results from a comparison of the mechanisms of diseases. This would ultimately result in a general theory of disease linked with our most general theories on living beings, among them, systems biology and network medicine. Before undertaking such a task, preliminary questions arise: is it likely that there are biological features common to different types of disease? Is it a philosopher’s job to determine what they consist in? What use would such a general theoretical definition of disease be? (shrink)

The thesis that natural selection explains the frequencies of traits in populations, but not why individual organisms have the traits tehy do, is here defended and elaborated. A general concept of ‘distributive explanation’ is discussed.

The question of whether humans have free will, like the question of the meaning of life, is one whose answer depends on how the question itself is interpreted. In his recent book Neurophilosophy of Free Will: From Libertarian Illusions to a Concept of Natural Autonomy, Henrik Walter examines whether free will is possible in a deterministic natural world, and he concludes that the answer is "It depends" (xi). He rejects a libertarian account of free will as internally (...) inconsistent, but argues for a version of compatibilism that he calls "natural autonomy." Natural autonomy, or "giving oneself laws" (8), is a successor concept to libertarian free will, and it provides for a self-determination that is consistent with a deterministic and fully physical world. Walter covers a lot of ground in this book. He debunks dualism, examines classical and modern physics, critiques radical constructivism, and utilizes chaos theory, and he refers to figures from St. Augustine to Humberto Maturana, Dennett, Einstein, Hegel and Nozick. This book could be seen as encompassing two distinct projects. The first project is a defense of what Walter calls "neurophilosophy" as a methodology for answering traditional philosophical questions. This methodology is more commonly known as "cognitive science," and Walter accepts the naturalistic premises that underlie most of the work being done by cognitive scientists today. The second project is an application of the neurophilosophical methodology to the traditional question of whether free will is compatible with determinism. The defense of a neurophilosophical methodology is concentrated in the second section of the book, whereas the first and third sections focus on the issue of free will. In the first section Walter presents a thorough overview of the free will debate. It is the final third of the book that warrants the most attention, for this is where the original work is concentrated. Before we examine Walter's contribution to the free will debate, let us briefly look at his historical analysis and the neurophilosophical method that he advocates.. (shrink)

The concept of property is integral to personal and societal development, yet understanding of the cognitive basis of ownership is limited. Objects are the most basic form of property, so our physical interactions with owned objects may elucidate nuanced aspects of ownership. We gave participants a coffee mug to decorate, use and keep. The experimenter also designed a mug of her own. In Experiment 1, participants performed natural lifting actions with each mug. Participants lifted the Experimenter’s mug with (...) greater care, and moved it slightly more towards the Experimenter, while they lifted their own mug more forcefully and drew it closer to their own body. In Experiment 2, participants responded to stimuli presented on the mug handles in a computer-based stimulus–response compatibility task. Overall, participants were faster to respond in trials in which the handles were facing in the same direction as the response location compared to when the handles were facing away. The compatibility effect was abolished, however, for the Experimenter’s mug – as if the action system is blind to the potential for action towards another person’s property. These findings demonstrate that knowledge of the ownership status of objects influences visuomotor processing in subtle and revealing ways. (shrink)

The goal of this paper is to sketch an empiricist metaphysics of laws of nature. The key idea is that there are regularities without regularity-enforcers. Differently put, there are natural laws without law-makers _of a distinct metaphysical kind_. This sketch will rely on the concept of a natural pattern and more significantly on the existence of a network of natural patterns in nature. The relation between a regularity and a pattern will be analysed in terms of (...) mereology. Here is the road map. In section 2, I will briefly discuss the relation between empiricism and metaphysics, aiming to show that an empiricist metaphysics is possible. In section 3, I will offer arguments against stronger metaphysical views of laws. Then, in section 4 I will motivate nomic objectivism. In section 5, I will address the question ‘what is a regularity?’ and will develop a novel answer to it, based on the notion of a natural pattern. In section 6, I will raise the question: ‘what is a law of nature?’, the answer to which will be: a law of nature is a regularity that is characterised by the unity of a _natural_ pattern. (shrink)

The main objective of this paper is to sketch unifying conceptual and formal framework for inference that is able to explain various proof techniques without implicitly changing the underlying notion of inference rules. We base this framework upon the so-called two-dimensional, i.e., deduction to deduction, account of inference introduced by Tichý in his seminal work The Foundation’s of Frege’s Logic (1988). Consequently, it will be argued that sequent calculus provides suitable basis for such general concept of inference and therefore (...) should not be seen just as technical tool, but philosophically well-founded system that can rival natural deduction in terms of its “naturalness”.

Darwin's theory of evolution by natural selection provided the first, and only, causal-mechanistic account of the existence of adaptations in nature. As such, it provided the first, and only, scientific alternative to the “argument from design”. That alone would account for its philosophical significance. But the theory also raises other philosophical questions not encountered in the study of the theories of physics. Unfortunately the concept of natural selection is intimately intertwined with the other basic concepts of evolutionary (...) theory—such as the concepts of fitness and adaptation —that are themselves philosophically controversial. Fortunately we can make considerable headway in getting clear on natural selection without solving all of those outstanding problems. (shrink)

_Philosophy of Right_ remains among the most influential works in Western political theory. It introduces a notion of civil society that has proven of inestimable importance to diverse philosophical and social agendas. In this transcription of the lectures that formed the initial version of Hegel's text, the philosopher presents his thought with a clarity and directness seldom matched in his later writings. Nowhere does Hegel make clearer the difference between his concept of objective spirit and traditional concepts of (...) class='Hi'>natural law. Nowhere does he offer a more prominent treatment of the key notion of recognition. The long-awaited appearance of this first English-language translation of these lectures is a major event for Hegel scholars, philosophers, and political theorists. (shrink)

Liberty and Law examines a previously underappreciated theme in legal history―the idea of permissive natural law. The idea is mentioned only peripherally, if at all, in modern histories of natural law. Yet it engaged the attention of jurists, philosophers, and theologians over a long period and formed an integral part of their teachings. This ensured that natural law was not conceived of as merely a set of commands and prohibitions that restricted human conduct, but also as affirming (...) a realm of human freedom, understood as both freedom from subjection and freedom of choice. Freedom can be used in many ways, and throughout the whole period from 1100 to 1800 the idea of permissive natural law was deployed for various purposes in response to different problems that arose. It was frequently invoked to explain the origin of private property and the beginnings of civil government. Several kinds of permissive natural law were identified. Permission could be positive or negative, depending on whether it was specifically conceded by a legislator or only tacitly allowed. It could free from sin or merely remit some temporal punishment that was due. It could commend some conduct without commanding it or permit some evil without condoning it. Medieval canonists used the concept of permissive natural law to harmonize the discordant texts that they found in their sources; William of Ockham found it a powerful tool in his defense of Franciscan poverty against papal criticisms; for Richard Hooker it justified both the constitutional structure and the ritual practices of the Anglican church; John Selden used it to uphold the inviolability of contracts, most importantly the contract of government; Hugo Grotius made it a central theme in his treatment of the conduct permissible in waging war; in the eighteenth century Jean Barbeyrac and Jean-Jacques Burlamaqui associated the idea with the emerging doctrine of natural rights. In Liberty and Law, Tierney has presented us with a magisterial and provocative way of interpreting legal history. (shrink)

Scientific perspectivism, or perspectival realism, is a view according to which scientific knowledge is neither utterly objective nor independent of the world “as it is”, but always tied to some particular ways of conceptualization and interaction with Nature. In the present paper, I employ Robert Rosen’s concept of the modeling relation for arguing that there are two basic reasons why our knowledge of natural systems is perspectival in this sense. The first of these pertains to the dualism between (...) a system and its environment, which is necessarily imposed by a scientist focusing on the former. The second pertains to the complexity of complex systems; a complex system understood as a system in which different kinds of causal entailments intertwine together. As I discuss in the paper besides developing the argument, perspectivism thus understood ties together several issues ranging from organicism to emergentism and to processual philosophy, and from the ceteris paribus talk of biology to the measurement problem of quantum mechanics. I also discuss Rosen’s relational formalisms as a concrete example of how perspectival epistemology might directly suggest novel strategies and practices of doing theoretical science. (shrink)

Inspired by the work of prominent University of Notre Dame political philosophers Catherine Zuckert and Michael Zuckert, this volume of essays explores the concept of natural right in the history of political philosophy. The central organizing principle of the collection is the examination of the idea of natural justice, identified in the classical period with natural right and in modernity with the concept of individual natural rights. Contributors examine the concept of natural (...) right and rights in all the manifold and interdisciplinary dimensions associated with the Zuckerts’ oeuvre. Part I explores the theme of natural right in the ancient and medieval political philosophy of Plato, Xenophon, Aristotle, and St. Augustine. Part II examines the early modern break from the classical tradition in the work of Montaigne, Spinoza, Montesquieu, Locke, and Hegel as well as the legacy of the modern natural rights tradition as explored by Leo Strauss and Pope John Paul II. Part III treats the theme of natural rights from the Puritans through the Founding period in such figures as Thomas Jefferson and Gouverneur Morris and up to the Progressive era with Booker T. Washington and Theodore Roosevelt. Part IV addresses questions of natural justice in literature, including works of Euripides, Cervantes, Shakespeare, Edith Wharton, and Tom Stoppard. "In this collection compiled in honor of Catherine and Michael Zuckert, the contributors address a wonderful variety of serious issues in important literary and philosophic texts. Their topics range from Plato on piety to Stoppard on socialist utopianism, and from Aristotle and Augustine to Euripides, Locke, Hegel, Shakespeare, and Booker T. Washington. The volume stands as an impressive introduction to the liberal arts and a lively introduction to many great issues of liberalism, Christianity, justice, and liberty; it is also a tribute to the Zuckerts' breadth of study, teaching, and influence." —_Robert K. Faulkner, Boston College_. (shrink)

Consider people’s ordinary concept of belief. This concept seems to pick out a particular psychological state. Indeed, one natural view would be that the concept of belief works much like the concepts one finds in cognitive science – not quite as rigorous or precise, perhaps, but still the same basic type of notion. But now suppose we turn to other concepts that people ordinarily use to understand the mind. Suppose we consider the concept happiness. Or (...) the concept love. How are these concepts to be understood? One obvious hypothesis would be that they are best understood as being more or less like the concept of belief. Maybe these concepts, too, pick out a particular mental state and thereby enable people to predict, explain and understand others’ behavior. We will argue that this hypothesis is mistaken. Instead, we suggest that the different concepts people use to understand the mind are fundamentally different from each other. Some of these concepts do indeed serve simply to pick out a particular mental state, but others allow a role for evaluative judgments. So, for example, our claim will be that when people are wondering whether a given agent is truly ‘happy’ or ‘in love,’ they are not merely trying to figure out whether this agent has a particular sort of mental state. They are also concerned in a central way with evaluating the agent herself. In short, our aim is to point to a striking sort of difference between the different concepts that people use to pick out psychological attitudes. We will be.. (shrink)

The recent widespread shift in governance from the state to the market and to civil society, in combination with the simultaneous shift from the national level to supra-national and sub-national levels has led to a significant increase in the numbers of public and private players in nature policy. This in turn has increased the need for a common vocabulary to articulate and communicate views and values concerning nature among various actors acting on different administrative levels. In this article, we will (...) examine the role of concepts of nature as communicative devices in public debates and political decision-making. We try to show that the now dominant functionalist approach to concepts of nature, due to its focus on interests, threatens to narrow public and political communications to purely strategic negotiations. Instead of this functionalist approach we put forward a structuralist approach, which focuses not on interests but on values. (shrink)

These lectures constitute the earliest version of Hegel's Philosophy of Right, one of the most influential works in Western political theory. They introduce a notion of civil society that has proven of inestimable importance to diverse philosophical and social agendas. This transcription of the lectures, which remained in obscurity until 1982, presents the philosopher's social thought with clarity and boldness. It differs in some significant respects from Hegel's own published version of 1821. Nowhere does Hegel make plainer the difference between (...) his concept of objective spirit and traditional concepts of natural law or offer a more prominent treatment of the key notion of recognition. His description of poverty is more forceful and his critique of existing social conditions more thorough than in the published edition, which had to satisfy the Prussian censor. The strictly limited powers of the monarch are more clearly delineated in the Heidelberg lectures, and the arguments for a bicameral legislature are more explicit. Hegel formulates in a more dynamic way his understanding of the relationship between rationality and actuality--the rational is not what exists but what is coming into being--and sets forth more simply and clearly the central themes of his political philosophy--freedom, justice, and community. The Heidelberg lectures are an indispensable resource for understanding the edition of 1821 and an invaluable supplement to one of the great classics of political philosophy. (shrink)

Building on work by Popper, Schweber, Nozick, Sober, and others in a still-growing literature, I explore here the conceptual kinship between Adam Smith''s ''invisible hand'' and Darwinian natural selection. I review the historical ties, and examine Ullman -Margalit''s ''constraints'' on invisible-hand accounts, which I later re-apply to natural selection, bringing home the close relationship. These theories share a ''parent'' principle, itself neither biological no politico-economic, that collective order and well-being can emerge parsimoniously from the dispersed action of individuals. (...) The invisible hand operates on ''memes'' the way natural selection operates on genes. Like Darwin''s concept, it brings together traditional opposites, ''nature'' and ''selection,'' forming a saltation-mitigating transition between biological instinct and full-blown conscious design. Herschel''s criterion of confirmation, which Darwin long strove to satisfy, is itself an invisible hand-like meme – a ''Midas effect'' revealing and rewarding the fittest theories, Darwin''s and Smith''s emphatically among them.

The central importance of Marx's concept of nature in the formulation of historical materialism has been largely neglected in the extensive literature on Marx. Alfred Schmidt, philosophical successor to Max Horkheimer and Theodor Adorno in Frankfurt, seeks to elucidate it in this original study.

This paper focuses on local constructions of ‘nature’ in governance processes, and the importance of historical and institutional contexts for their genesis and functioning. Through extensive field study in the Romanian Danube Delta, it is demonstrated that the origin and distribution of certain concepts can be credited to a history of conflicts over land and resource use. Considering the implications for participatory natural resource governance, we argue that this capacity of the governance context to produce and transform concepts of (...) nature, poses real challenges. To these challenges can be added legacies of disempowerment and marginalisation, evident in local inhabitants’ images and concepts of nature, which we seek to understand by developing a theory of traumatic nature.

Darwin provided us with a powerful theoretical framework to explain the evolution of living systems. Natural selection alone, however, has sometimes been seen as insufficient to explain the emergence of new levels of selection. The problem is one of “circularity” for evolutionary explanations: how to explain the origins of Darwinian properties without already invoking their presence at the level they emerge. That is, how does evolution by natural selection commence in the first place? Recent results in experimental evolution (...) suggest a way forward: Paul Rainey and his collaborators have shown that Darwinian properties could be exogenously imposed via what they call “ecological scaffolding.” This could solve the “black box” dilemma faced by Darwinian explanations of new levels of organization. Yet, despite “scaffolding” recently becoming a popular term in the study of cognition, culture, and evolution, the concept has suffered from vagueness and ambiguity. This article aims to show that scaffolding can be turned into a proper scientific concept able to do explanatory work within the context of the major evolutionary transitions. Doing so will allow us to once again extend the scope of the Darwinian model of evolution by natural selection. (shrink)

Until the second half of the 19th century the natural numbers were regarded as given and not further analysable. The concept of a class as defined by mathematicians of the time, Seeming more fundamental, Was then used to define the natural numbers. Their definitions of a class are unsuitable because of paradoxes and other difficulties. In this paper a new definition of a class is stated, And from this the natural numbers are defined.

In the last hundred years, the philosophy of natural law has suffered a fate that could hardly have been envisaged by the seventeenth and eighteenth century exponents of its universality and eternity: it has become old-fashioned. The positivists and the Marxists were happy to throw eternal moral ity out of the window, confident that some magic temporal harmony would eventually follow Progress in by the front door. Their hopes may not have been fully realized, but they did succeed in (...) discrediting natural law. What is often not appreciated is the extent to which we have adopted the tenets of the philosophy they despised, borh in the field of politics, and in the field of personal and social ethics, which Barbeyrac called "la science des mreurs" and which the positivists re christened "social science". Consequently, though we live in a world whose freedom, such as it is, is largely a result of the popularization of the philosophy of natural law, and whose conscious and unconscious standards, such as they are, are a result of that philosophy as it became combined with Christianity, the doctrine of natural law is itself for gotten. In view of the oblivion into which it has fallen, natural law is a concept which means little to the average reader. All too often, Montesquieu scholars have traded on this oblivion in order to give an exaggerated picture of his originality. (shrink)

‘Natural-History’ is one of the key concepts in the thought of the Frankfurt School critical theorist Theodor W. Adorno, appearing from his very earliest work through to his very last. Unfortunately, the existing literature provides little illumination as to what Adorno’s concept of natural-history is, or what it is supposed to do. This paper thus seeks to supply the required understanding. Ultimately, I argue that ‘natural-history’ is best understood as a sort of ‘therapeutic’ concept, intended (...) to dissolve certain philosophical anxieties which might otherwise present obstacles to our being able to obtain a critical-theoretical understanding of reality.

Theoreticians that defend a form of realism regarding natural kinds minimally entertain the belief that the world features divisions into kinds and that the natural kind concept is a useful tool for philosophy of science. The objective of this paper is to challenge these assumptions. First, we challenge realism toward natural kinds by showing that the main arguments for their existence, which rely on the epistemic success of natural kinds, are unsatisfactory. Second, we show that, (...) whether they exist or not, natural kinds are expendable when it comes to describing and analyzing scientific explanations accurately. (shrink)

Frege's main contributions to logic and the philosophy of mathematics are, on the one hand, his introduction of modern relational and quantificational logic and, on the other, his analysis of the concept of number. My focus in this paper will be on the latter, although the two are closely related, of course, in ways that will also play a role. More specifically, I will discuss Frege's logicist reconceptualization of the natural numbers with the goal of clarifying two aspects: (...) the motivations for its core ideas; the step-by-step development of these ideas, from Begriffsschrift through Die Grundlagen der Arithmetik and Grundgesetze der Arithmetik to Frege's very last writings, indeed even beyond those, to a number of recent "neo-Fregean" proposals for how to update them. One main development, or break, in Frege's views occurred after he was informed of Russell's antinomy. His attempt to come to terms with this antinomy has found some attention in the literature already. It has seldom been analyzed in connection with earlier changes in his views, however, partly because those changes themselves have been largely ignored. Nor has it been discussed much in connection with Frege's basic motivations, as formed in reaction to earlier positions. Doing both in this paper will not only shed new light on his response to Russell's antinomy, but also on other aspects of his views. In addition, it will provide us with a framework for comparing recent updates of these views, thus for assessing the remaining attraction of Frege's general approach. I will proceed as follows: In the first part of the paper (§1.1 and §1.2), I will consider the relationship of Frege's conception of the natural numbers to earlier conceptions, in particular to what I will call the "pluralities conception", thus bringing into sharper focus his core ideas and their motivations. In the next part (§2.1 and §2.2), I will trace the order in which these ideas come up in Frege's writings, as well as the ways in which his position gets modified along the way, both before and after Russell's antinomy..
