'If' is one of the most important words in the English language, being used to express hypothetical thought. The use of conditional terms such as 'if' distinguishes human intelligence from that of all other animals. In this volume, Jonathan Evans and David Over present a new theoretical approach to understanding conditionals. The book draws on studies from the psychology of judgement and decision making, as well as philosophical logic.

Rodden writes, “How do stories persuade us? How do they ‘move’—and move us? The short answer: by analogies.” Rodden’s claim is a natural first view, also held by others. This chapter considers the extent to which this view is true and helpful in understanding how fictional narratives, taken as wholes, may be argumentative, comparing it to the two principal (though not necessarily exclusive) alternatives that have been proposed: understanding fictional narratives as exhibiting the structure of suppositional argument, or the (...) structure of a kind of transcendental argument. Three key aspects of understanding a fictional narrative as an argument from analogy are identified. First, the argument will be relativistic or depend in an essential way upon the circumstances or intentions of the auditor or author. Second, in view of the first aspect, the argument will be loose and subjective, and accordingly less likely to yield knowledge. Third, the argument will not exhibit a distinctive structure applicable only to fictional narratives. I find that the third, and sometimes the first and second, of these same three aspects apply to understanding fictional narratives as suppositional arguments. I present considerations that point to a way of establishing that some extended fictions exhibit the structure of a kind of transcendental argument that is neither relativistic nor subjective, is knowledge-generating, and is uniquely applicable to fictional narratives. This supports literary cognitivism—the thesis that “literary fiction can be a source of knowledge in a way that depends crucially on its being fictional.”. (shrink)

In this paper, Ockham's theory of an ideal language of thought is used to illuminate problems of interpretation of his theory of truth. The twentieth century idea of logical form is used for finding out what kinds of atomic sentences there are in OckhamÕs mental language. It turns out that not only the theory of modes of supposition, but also the theory of supposition in general is insufficient as a full theory of truth. Rather, the theory of supposition is (...) a theory of reference, which can help in the determination of truth values within the scope of simple predications. Outside this area, there are interesting types of sentences, whose truth does not depend on whether the terms supposit for the same things or not for the same things. (shrink)

When one thinks—knows, believes, imagines—that something is the case, one’s thought has a topic: it is about something, towards which one’s mind is directed. What is the logic of thought, so understood? This book begins to explore the idea that, to answer the question, we should take topics seriously. It proposes a hyperintensional account of the propositional contents of thought, arguing that these are individuated not only by the set of possible worlds at which they are true, (...) but also by their topic: what they are about. The book then builds epistemic, doxastic, probabilistic, and conditional logics based on this view. It applies them to issues ranging from dogmatism, scepticism, and epistemic fallibilism, to imagination and suppositional reasoning, belief revision, framing effects, and the acceptability of indicative conditionals.

Suppositional reasoning can seem spooky. Suppositional reasoners allegedly (e.g.) “extract knowledge from the sheer workings of their own minds” (Rosa), even where the knowledge is synthetic a posteriori. Can literary fiction pull such a rabbit out of its hat? Where P is a work’s fictional ‘premise’, some hold that some works reason declaratively (supposing P, Q), imperatively (supposing P, do Q), or interrogatively (supposing P, Q?), and that this can be a source of knowledge if the reasoning is (...) good. True, I will argue, although only within the context of judicious critical interpretation. Further evident constraints include that the form of the suppositional reasoning needs to be declarative or imperative, and that the fictional ‘premise’ of the work needs to be a metaphysical counterfactual possibility, not merely a temporal counterfactual and not merely an epistemic possibility or probabilistic supposition.

This dissertation is devoted to empirically contrasting the Suppositional Theory of conditionals, which holds that indicative conditionals serve the purpose of engaging in hypothetical thought, and Inferentialism, which holds that indicative conditionals express reason relations. Throughout a series of experiments, probabilistic and truth-conditional variants of Inferentialism are investigated using new stimulus materials, which manipulate previously overlooked relevance conditions. These studies are some of the first published studies to directly investigate the central claims of Inferentialism empirically. In contrast, the (...) Suppositional Theory of conditionals has an impressive track record through more than a decade of intensive testing. The evidence for the Suppositional Theory encompasses three sources. Firstly, direct investigations of the probability of indicative conditionals, which substantiate “the Equation” (P(if A, then C) = P(C|A)). Secondly, the pattern of results known as “the defective truth table” effect, which corroborates the de Finetti truth table. And thirdly, indirect evidence from the uncertain and-to-if inference task. Through four studies each of these sources of evidence are scrutinized anew under the application of novel stimulus materials that factorially combine all permutations of prior and relevance levels of two conjoined sentences. The results indicate that the Equation only holds under positive relevance (P(C|A) – P(C|¬A) > 0) for indicative conditionals. In the case of irrelevance (P(C|A) – P(C|¬A) = 0), or negative relevance (P(C|A) – P(C|¬A) < 0), the strong relationship between P(if A, then C) and P(C|A) is disrupted. This finding suggests that participants tend to view natural language conditionals as defective under irrelevance and negative relevance (Chapter 2). Furthermore, most of the participants turn out only to be probabilistically coherent above chance levels for the uncertain and-to-if inference in the positive relevance condition, when applying the Equation (Chapter 3). Finally, the results on the truth table task indicate that the de Finetti truth table is at most descriptive for about a third of the participants (Chapter 4). Conversely, strong evidence for a probabilistic implementation of Inferentialism could be obtained from assessments of P(if A, then C) across relevance levels (Chapter 2) and the participants’ performance on the uncertain-and-to-if inference task (Chapter 3). Yet the results from the truth table task suggest that these findings could not be extended to truth-conditional Inferentialism (Chapter 4). On the contrary, strong dissociations could be found between the presence of an effect of the reason relation reading on the probability and acceptability evaluations of indicative conditionals (and connate sentences), and the lack of an effect of the reason relation reading on the truth evaluation of the same sentences. A bird’s eye view on these surprising results is taken in the final chapter and it is discussed which perspectives these results open up for future research. (shrink)

Timothy Williamson contends that our primary cognitive heuristic for prospectively assessing conditionals, i.e., the suppositional procedure, is provably inconsistent. Our diagnosis is that stipulations about the nature of suppositional rejection are the likely source of these results. We show that on at least one alternative, and quite natural, understanding of the suppositional attitudes, the inconsistency results are blocked. The upshot is an increase in the reliability of our suppositional heuristics across a wider range of contexts. One (...) interesting consequence of the increased reliability is a proportional decrease in the plausibility of an error-theory that Williamson employs against widespread intuitions about the truth values of counterpossible conditionals.

According to many forms of Externalism now popular in the Philosophy of Mind, the contents of our thoughts depend in part upon our physical or social milieu.1 These forms of Externalism leave unchallenged the thesis that the ~non-factive! attitudes we bear towards these contents are independent of physical or social milieu. This paper challenges that thesis. It is argued here that publicly forwarding a content as a supposition for the sake of argument is, under conditions not themselves guaranteeing the existence (...) of that state, sufficient for occupancy of the intentional state of supposing that content. Because a saying may literally create an intentional state, whether one is in such a state does not depend solely upon how things are within one’s skin. Rather, even leaving content fixed, the attitude borne toward that content depends in part upon what norms are in force in one’s milieu. (shrink)

Unlike in physics, the category of thought experiment is not very common in biology. At least there are no classic examples that are as important and as well-known as the most famous thought experiments in physics, such as Galileo’s, Maxwell’s or Einstein’s. The reasons for this are far from obvious; maybe it has to do with the fact that modern biology for the most part sees itself as a thoroughly empirical discipline that engages either in real natural history (...) or in experimenting on real organisms rather than fictive ones. While theoretical biology does exist and is recognized as part of biology, its role within biology appears to be more marginal than the role of theoretical physics within physics. It could be that this marginality of theory also affects thought experiments as sources of theoretical knowledge. Of course, none of this provides a sufficient reason for thinking that thought experiments are really unimportant in biology. It is quite possible that the common perception of this matter is wrong and that there are important theoretical considerations in biology, past or present, that deserve the title of thought experiment just as much as the standard examples from physics. Some such considerations may even be widely known and considered to be important, but were not recognized as thought experiments. In fact, as we shall see, there are reasons for thinking that what is arguably the single most important biological work ever, Charles Darwin’s On the Origin of Species, contains a number of thought experiments. There are also more recent examples both in evolutionary and non-evolutionary biology, as we will show. Part of the problem in identifying positive examples in the history of biology is the lack of agreement as to what exactly a thought experiment is. Even worse, there may not be more than a family resemblance that unifies this epistemic category. We take it that classical thought experiments show the following characteristics: They serve directly or indirectly in the non-empirical epistemic evaluation of theoretical propositions, explanations or hypotheses. Thought experiments somehow appeal to the imagination. They involve hypothetical scenarios, which may or may not be fictive. In other words, thought experiments suppose that certain states of affairs hold and then try to intuit what would happen in a world where these suppositions are true. We want to examine in the following sections if there are episodes in the history of biology that satisfy these criteria. As we will show, there are a few episodes that might satisfy all three of these criteria, and many more if the imagination criterion is dropped or understood in a lose sense. In any case, this criterion is somewhat vague in the first place, unless a specific account of the imagination is presupposed. There will also be issues as to what exactly “non-empirical” means. In general, for the sake of discussion we propose to understand the term “thought experiment” here in a broad rather than a narrow sense here. We would rather be guilty of having too wide a conception of thought experiment than of missing a whole range of really interesting examples. (shrink)

In Constructing the World, Chalmers observes that our knowledge exceeds the core evidence provided by our senses and introspection. Thus, on the basis of core evidence, one also can know (S) that water covers the majority of the Earth. This knowledge, Chalmers suggests, requires a great deal of apriori knowledge. Chalmers argues that even if one suspends belief in one’s core evidence, one can nevertheless reason from a description of this evidence to an ordinary claim such as S. Chalmers concludes (...) that the ordinary claim must be apriori entailed by a description of the core evidence. However, I propose that careful thinking about belief suspension reveals that empirical information can contaminate the reasoning from the core evidence to the ordinary claim S, even if belief in the core evidence is suspended. One result is that empiricists and externalists may freely appeal to thought experiments without having to concede that there are substantive apriori truths. (shrink)

The relationship between thought and reality was a focal point of Wyclif’s reflection. On the one hand, Wyclif believed that thought was linguistically constrained by its own nature; on the other hand, he considered thought to be related to reality in its elements and constitution. Hence he deemed language, thought, and external reality to be of the same logical coherence. Within this context, the theory of supposition was intended to explain the different roles that terms can (...) have in relation to language and the extra-mental world when they appear as extremes in propositions. Characteristically, his theory of supposition provides an account not only of the truth-values of a sentence, but also of its meaning; it is not therefore simply a theory of reference, but a sort of complex analysis of language viewed as a semiotic system whose unique interpretative model was reality itself. It gives clear evidence of Wyclif’s realist stance and of his conviction that any kind of linguistic and semantic features must be grounded on ontological structures. (shrink)

David Bloor’s thought experiment is taken into consideration to suggest that the rationality of the Other cannot be inferred by way of argument for the reason that it is unavoidably contained as a hidden supposition by any argument engaged in proving it. We are able to understand a different culture only as far as we recognize in it the same kind of rationality that works in our own culture. Another kind of rationality is either impossible, or indiscernible.

In his Welcome Message for the XXII World Congress of Philosophy hosted by Seoul National University in August 2008 the President of the International Federation of Philosophical Societies (FISP), Peter Kemp, said that—inter alia—it will be an occasion “for rethinking the great philosophical questions.” Amongst there questions how we in the present understand the philosophical past is surely a perennial query before us. In this short paper I will refer to the endeavor of understanding past philosophical thought on its (...) own terms or as presented in a current idiom as “philosophical translation.” The latter can take three forms: logical, analytical, or hermeneutic. This paper will briefly discuss all three forms vis-à-vis modern attempts to understand the medieval concept of “supposition” with special regard to the role metalanguage plays in philosophical translation.

This edited volume presents new lines of research dealing with the language of thought and its philosophical implications in the time of Ockham. It features more than 20 essays that also serve as a tribute to the ground-breaking work of a leading expert in late medieval philosophy: Claude Panaccio. Coverage addresses topics in the philosophy of mind and cognition (externalism, mental causation, resemblance, habits, sensory awareness, the psychology, illusion, representationalism), concepts (universal, transcendental, identity, syncategorematic), logic and language (definitions, syllogisms, (...) modality, supposition, obligationes, et cetera), action theory (belief, will, action), and more. A distinctive feature of this work is that it brings together contributions in both French and English, the two major research languages today on the main theme in question. It unites the most renowned specialists in the field as well as many of Claude Panaccio's former students who have engaged with his work over the years. In furthering this dialogue, the essays render key topics in fourteenth-century thought accessible to the contemporary philosophical community without being anachronistic or insensitive to the particularities of the medieval context. As a result, this book will appeal to a general population of philosophers and historians of philosophy with an interest in logic, philosophy of language, philosophy of mind, and metaphysics.

Wittgenstein wrote: “No supposition seems to me more natural than that there is no process in the brain correlated with associating or with thinking; so that it would be impossible to read off thought-processes from brain processes.” In general, he rejects what he calls “psycho-physical parallelism.” In Sect. 1, I explain Wittgenstein’s position on this topic and how his followers defend it. In Sect. 2, I argue against Wittgenstein, contending that there is “thought” in a wider sense and (...) that it can be “manifested” without expression. Thought does not need to be ordinarily expressed or even expressible, and it can be read off from the brain, provided one has sufficient technology, data, and understanding of the subject’s interaction with the environment. In Sect. 3, I offer results from brain-science in support of my claims. (shrink)

This paper argues that Burley's theory of simple supposition is not as it has usually been presented. The prevailing view is that Burley and other authors agreed that simple supposition was in every case supposition for a universal, and that the disagreement over simple supposition between, say, Ockham and Burley was merely a disagreement over what a universal was (a piece of the ontology? a concept?), combined with a separate disagreement over what terms signify (the speaker's thoughts? the objects the (...) thoughts are about?).In fact, however, Burley explicitly allows that some instances of simple supposition are for an individual, and that in certain cases personal supposition and simple supposition coincide. The present paper explores Burley's theory on this topic, and proposes a way of thinking about the metaphysics and the semantics that makes sense of what he says. (shrink)

The ability of the mind to conceptualize what is not present is essential. It allows us to reason counterfactually about what might have happened had events unfolded differently or had another course of action been taken. It allows us to think about what might happen – to perform 'Gedankenexperimente' (thought experiments) – before we act. However, the cognitive and neural mechanisms mediating this ability are poorly understood. We suggest that the frontopolar cortex (FPC) keeps track of and evaluates alternative (...) choices (what we might have done), whereas the anterior lateral prefrontal cortex (alPFC) compares simulations of possible future scenarios (what we might do) and evaluates their reward values. Together, these brain regions support the construction of suppositional scenarios. (shrink)

In “On the Nature of Logical Judgment” (published 1893) and A New Law of Thought and Its Logical Bearings (published 1911), E. E. Constance Jones developed a view on which we can think and talk about the round-square. On her view, the round-square has a kind of existence; otherwise, sentences about it wouldn’t be meaningful. But it doesn’t exist in space, since it’s both round and square, and nothing in space is both. Although it has a kind of existence (...) in what she calls “a Region of Supposition,” we can truly say that it “doesn’t exist,” if what we mean is that it doesn’t exist in space. It plays a role in reasoning, since we need to be able to reason about it to conclude that it doesn’t exist in space. And, although the round-square is both round and square, the Law of Contradiction needn’t be violated, provided that it’s understood in light of Jones’s distinction between two kinds of negation.

We find a simple counterfactual acceptable, it is argued, to the extent that (i) our probability of the consequent under the thought experiment of counterfactually supposing the antecedent is high, (ii) provided the latter is on-topic with respect to the former. Counterfactual supposition is represented by Lewisian imaging. Topicality, by an algebra of subject matters. A topic-sensitive probabilistic logic is then provided, to reason about the acceptability of simple counterfactuals.

The “dragon” that graces the cover of this volume has a story that goes with it. In the summer of 1980, I was on the teaching staff of the Summer Institute on Medieval Philosophy held at Cornell University under the direction of Norman Kretzmann and the auspices of the Council for Philosophical Studies and the National Endowment for the Humanities. While I was giving a series of lectures there (lectures that contribute to this volume, as it turns out), I went (...) to my office one morning, and there under the door some anonymous wag from the Institute had slid the pen and ink drawing you see in the picture. It represents “Supposition” as a dragon, making a rude face at the viewer. The tail of the dragon is divided — not entirely accurately, as it turns out — into the various branches and subbranches of supposition. If the details are not altogether correct, the spirit is certainly understandable. (shrink)

The purpose of this book is to construct a naturalistic theory of meaning. Millikan starts with two suppositions. First, like the devices of many other biological systems, "we suppose that normally a natural-language device has continued to be proliferated only because it has served a describable, stable function or set of functions." Second, like the operative features of many other biological devices, "speaker utterances of a language device presumably are proliferated only in so far as stable overt or covert reactions (...) by cooperating partners... are also proliferated." From these naturalistic suppositions the notion of proper function is derived, refined, and applied to language devices. This provides a basis for a naturalistic explanation of intentionality as well as for the development of what Millikan calls "Fregean" sense, which she sharply distinguishes from intensionality. For Millikan we may have different "iterated programs" for recognizing for example, gold, but share the publicly construed sense of gold. Millikan then applies her theory of meaning to a number of problems in the philosophy of language including the references of indexicals, descriptions, and negations. Millikan provides further support for her theory of meaning by constructing a compatible theory of identity and a compatible epistemology. (shrink)

This dialogue on thought and language is a sequel to my dialogue ‘Thought and Thinking’, but can be read independently of it. The five disputants are the same as in the previous dialogue, namely Socrates; an imaginary neuroscientist from California ; an Oxford don from the 1950s ; a Scottish post-doctoral student; and John Locke. The discussion takes place in Elysium in the early evening after dinner. They discuss the relationship between what one thinks and what one says, (...) examine the reasons for supposing that there must be a language of thought and show why there cannot be one, investigate the supposition that thought must have a medium – that one must think in something – and demonstrate that it cannot have one. They investigate whether there can be non-linguistic thinking and whether non language-using animals can be said to think, and determine the limits of thought and thinking. (shrink)

This article raises two questions about Robert Myers and Claudine Verheggen's terrific book, Donald Davidson's Triangulation Argument: A Philosophical Inquiry. The first question, concerning the first part of the book, is whether, starting from the assumption that a solitary individual cannot have thought contents, we can show that adding another individual to the picture cannot resolve the problem. The second question, concerning the second part, is whether a more sophisticated, decision-theoretic, Humean about the pro-attitudes can respond to the objections (...) to the simple Humean view, and whether Davidson was not in fact just such a sophisticated decision-theoretic Humean. RÉSUMÉ: Cet article pose deux questions sur le formidable livre de Robert Myers et Claudine Verheggen, Donald Davidson's Triangulation Argument: A Philosophical Inquiry. La première question, qui concerne la première partie du livre, consiste à déterminer si, étant donné la supposition qu'un individu solitaire ne peut pas avoir de contenus mentaux, nous pouvons démontrer qu'ajouter un autre individu ne permet pas de résoudre le problème. La seconde question, qui concerne la deuxième partie du livre, est de savoir si un tenant d'une conception humienne des pro-attitudes plus sophistiquée, adhérant à la théorie de la décision, peut répondre aux objections formulées contre la simple conception humienne, et si Davidson n’était pas en fait un tenant de ce second type de conception humienne.

The question of [metaphysical logic] is how cogitatio is possible in the first place (Überhaupt – Kant) as it constitutes reaction to the real (whatever that may be) by the Ego (a subject possessed of cognitive potential). Is that reaction dependable?Ego can only react to the World. All systems of thought/cognition come from this only impact of reality.The question is its own reliability and legitimacy. The first can deliver reliably something quite illegitimate (the whole art of propaganda (advertising) is (...) based on this simple fact).The ability to cognize/think, at least at the level of [modern Ego] assumes the technique/capacity’s independence from that come from [categorical truisms]. To manipulate this is to think/cognize. Possible just when, the (shape of) the real resonates with Ego’s cognitive sensitivity. This needs to be shown to obtain.(Assuming per impossibile that the contrary obtains at the [archetypal] beginning our thinking could not find an adequate basis so it could not occur—which supposition is absurd.).

In a 1967 article, A. C. Graham made the claim that 情 qing should never be translated as "emotions" in rendering early Chinese texts into English. Over time, sophisticated translators and interpreters have taken this advice to heart, and qing has come to be interpreted as "the facts" or "what is genuine in one." In these English terms all sense of interrelationality is gone, leaving us with a wooden, objective stasis. But we also know, again partly through the work of (...) Graham, that interrelationality was of fundamental importance in the early Chinese cosmology and that qing, by later carrying the meaning of "emotions," expressed that interrelationality. I take as my project in this article the recovery of an emotional adumbration in the qing of early Chinese texts, notably the Mencius, from which Graham begins his discussion. With an eye to explicating qing in the Mencius, and with a sensitivity to an implied notion of interrelationality in early texts, I survey early literature from the Shu Jing to late commentaries on the Yi Jing. I find that usages of qing and contexts in which qing is used inevitably illuminate it as key term in the evocation of interrelationality, shading it with emotional overtones. Emotions, of course, are inherently interrelational, and even more so in a Chinese world in which the internal and the external are in constant communication by way of a cosmic interchange of arousal and response among all things. That qing, as a term which later comes to explicitly mean "emotions," should have a centuries old convention of emotional connotation prior to its explicit definition should come as no surprise. The corroboration of this supposition entails a complex investigation and analysis, however, and it is a preliminary step in this investigation and analysis that I undertake here. (shrink)

Now available in paperback, ____The Quarrel Between Philosophy__ ____and Poetry__ focuses on the theoretical and practical suppositions of the long-standing conflict between philosophy and poetry. Stanley Rosen--one of the leading Plato scholars of our day--examines philosophical activity, questioning whether technical philosophy is a species of poetry, a political program, an interpretation of human existence according to the ideas of 19th and 20th-century thinkers, or a contemplation of beings and Being.

This article attempts to defend Kwame Gyekye’s moderate communitarianism (MC) from the trenchant criticism that it is as defective as radical communitarianism (RC) since they both fail to take rights seriously. As part of my response, I raise two critical questions. Firstly, I question the supposition in the literature that there is such a thing as radical communitarianism. I point out that talk of radical communitarianism is tantamount to attacking a “straw-man.” Secondly, I question the efficacy of the criticism that (...) MC does not take rights seriously, given that there is no account of what it means to take rights seriously in the African tradition. This criticism, insofar as it does not specify a criterion of what it means to take rights seriously, remains defective. The central contribution of this article is to call our attention to the fact that the intellectual culture of rights will surely be affected by Afro-communitarianism, which emphasises our duties to all.

In lieu of an abstract, here is a brief excerpt of the content:146 BOOK REVIEWS the years passed since Father Garrigou-Lagrange last published his De Revelatione would have allowed Thomistic scholars to retrieve and de· velop Aquinas's theological insights in their fullness. The danger of apologetics is that it can lead one to develop a teaching only along the lines set by those challenging the traditional teaching of the Church. In this particular instance, the Catholic apologists of the antimodernist period (...) were led to overstress the epistemological dimension of the theology of Revelation, leaving unstated that for Saint Thomas the primary term of analysis in this question is the knowledge of God. The need of Revelation for Saint Thomas stems from the call to man to share in the beatific vision. A paper on the relation of finality between faith and the beatific vision would have underlined the originality and true significance of the Thomistic tradition in theology. Saint John's Priory Laredo, Texas JOSEPH D'AMECOURT, F.J. The Eternity of the World in the Thought of Thomas Aquinas and his Contemporaries. Edited by J. B. M. WISSINK. Studien und Texte zur Geistesgeschichte des Mittelalters, edited by A. ZIMMERMAN, vol. 27. Leiden: E. J. Brill, 1990. Pp. viii+ 100. $28.75 (paper). This volume contains six short studies by five different scholars from the Netherlands on a topic accurately indicated by its title. These studies are a product of a symposium held by the Thomas Aquinas Workgroup, a scholarly association dedicated to investigating the thesis " that Aquinas first of all has to be understood as a theologian " and to " a rediscovery of the original Aquinas and his authentic thought" (p. vii). The topic chosen for these studies is a suitable one for the aims of the Workgroup, for it is one that requires a clear dis· tinction to be made between the realms of philosophy and theology, and it is one that has generated much interest and dispute-in the Middle Ages no less than today. This small collection of studies makes a con· tribution to scholarship, although there are weaknesses in some of the studies, as I shall note. F. J. A. de Grijs (pp. 1-8) argues that Thomas's purpose in writing the De aeternitate mundi was theological rather than philosophical in that Thomas provides a meditation on the meaning of eternity. This meditation, so de Grijs argues, is not only about the temporal eternity of the world but is even more about God's eternity. It shows us how BOOK REVIEWS 147 little we grasp of God's duration, or how we do not understand it rather than how we do understand it. J. A. Aertsen (pp. 9-19) ·responds to de Grijs by arguing that the work has a philosophical character. First, Aertsen explains, the fact that Thomas begins the De aeternitate mundi with the supposition on faith that the world had a temporal beginning in the past does not of itself (as de Grijs had thought) mean that the work is theological. Rather, it simply means that all believers agree that in fact the world had a temporal beginning, but the question at issue remains a philosophical one: could the world possibly have existed eternally in the past? Second, Aertsen points out that the reasoning in the De aeternitate mundi is much like that of Thomas's Disputed Question De potentia Dei, q. 3, a. 14, which has an explicitly philosophical character. Third, Thomas has already made it clear in his Commentary on the Sentences, bk. 2, d. 1, q. 1, a. 2, that the doctrine of creation, excluding the part of the doctrine that the world had a temporal beginning, is philosophically knowable in principle and known to philosophers in fact. Since the fact of creation is philosophically knowable and can he demonstrated without prejudice to the question of eternity, it cannot he said that an eternal past existence is incompatible with creation. Hence, the question of the compatibility of being eternal and being created-the very question for the De aeternitate mundi-is regarded by Thomas as philosophical rather than as theological. Aertsen's criticisms of de Grijs are sound, yet de Grijs's central point can he saved. De Grijs... (shrink)

Enrique Leff holds that the profound causes of the environmental crisis are founded in dominant ways of knowing; that is to say, the crisis is rooted in the epistemological bases of modernity. Leff has systematically dedicated himself to proposing and constructing concepts that deconstruct modern suppositions, and at the same time, enable new ways of understanding and apprehending the world. His extensive work has succeeded in transcending and forging space for environmental thought, not only in education and environmental philosophy, (...) but also in the areas of economics, sociology, and development. His central argument is that these problems are the result of a crisis of civilization, and he urges all of us to rethink the foundations of modern rationality underlying contemporary global society.

Smartfounding is the opposite of “dumbfounding” introduced by Jonathan Haidt’s research on disgust. Dumbfounders have general competence at thought experiment. However, they are flustered by thought experiments that support repugnant conclusions. Instead of following the supposition wherever it leads, they avoid unsettling implications by adding extraneous information or ignoring stipulated conditions. The dumbfounded commit performance errors, often seeming to regress to the answers of people who lack formal schooling. Smartfounders retain their composure. They practice subversive compliance, obeying the (...) instructions in a way that spoils the aim of the thought experiment. Smartfounders offer a more sophisticated grade of resistance to thought experiment. Whereas the lower grades of resistance are merely fallacious, smartfounding often constitutes a penetrating internal critique of the thought experiment and sometimes of thought experiments in general.

Understanding the logical behavior of propositional attitudes, i.e. the mental states that we entertain with propositions (such as knowledge, belief, supposition, imagination, etc.), requires careful consideration of what such attitudes are about: their topic. This is the core intuition of Francesco Berto’s work, a book that fits into one of the most interesting and rich debates of recent decades, ranging over a wide variety of disciplines: from formal semantics to epistemology and even cognitive psychology. But above all, Berto’s book makes (...) a substantial contribution to what Daniel Nolan calls the hyperintensional revolution. In addition to being an original and ambitious proposal in the area of epistemic logic, the book can also be considered an excellent and in-depth introduction to many of the most interesting problems in the contemporary debate.

Against the common supposition that Adorno’s thinking remains caught in a distressing form of pessimism rendering it impotent in the face of modern capitalism and the fungibility of subjects, the article argues that the operation of negative dialectics inherently contains a productive moment that suggests the promise of a qualitatively different philosophy. Through an analysis that employs the multivalent senses of play at work in Adornian thinking — and particularly the notions of gamble, risk and chance — as its primary (...) interpretive key, the article shows that this promise for a philosophy ‘to come’ is at work in the use of parataxis and the practice of constellating concepts; in the invocation of metaphysical experience and affective language; and in the descriptions of critical philosophy as engaged in a practice of ‘critique and rescue’ or ‘wounded healing’.

No supposition seems to me more natural than that there is no process in the brain correlated with associating or with thinking; so that it would be impossible to read off thought processes from brain processes. I mean this: if I talk or write, there is, I assume, a system of impulses going out from my brain and correlated with my spoken or written thoughts. But why should the system continue further in the direction of the center? Why should (...) this order not proceed, so to speak, out of chaos? The case would be like the following—certain kinds of plants multiply by seed, so that a seed always produces a plant of the same kind as that from which it was produced—but nothing in the seed corresponds to the plant which..

Michelangelo thought that stone statues pre-exist their sculptors’ performance. Michelangelo’s view gives rise to a puzzle, which we call Michelangelo’s puzzle. Michelangelo’s puzzle looks structurally similar to so-called problems of material constitution ; so it is tempting to suppose that it can be similarly accounted for. This paper argues that the supposition is misguided. Michelangelo’s puzzle raises specific problems, which cannot be adequately dealt with unless one is prepared to give up either the natural view that stone sculptures are (...) human creations, or a very plausible principle concerning the persistence of middle-sized material objects. A tentative solution to the puzzle is provided, in which borders can play an ontological role in the making of material objects. This solution is intuitively more palatable than Michelangelo’s view, but is nonetheless at odds with a commonsensical, realist attitude towards material objects. Thus, Michelangelo’s puzzle poses a serious challenge to common sense, which is unparalleled by other problems of material constitution. (shrink)

Experimental results can in principle undermine the procedures of any intellectual community, by revealing patterns of variation in its members’ judgments that are hard to reconcile with the supposition that those judgments are even moderately reliable. Armchair philosophy typically involves the evaluation of constant stimuli, such as the scenario of a thought experiment, often presented by a written description, so in that respect Shanteau’s paper is encouraging. Jonathan Weinberg does not attempt to specify the psychological or social nature of (...) armchair philosophy. Jonathan M. Weinberg, Chad Gonnerman, Cameron Buckner, and Joshua Alexander describe the target of the experimentalist critique as “analytic philosophy’s longstanding practice of deploying armchair intuitive judgments about cases”. WGBA do try to identify some relevant differences between thought experiments and other cognitive tasks in philosophy in terms drawn from the scientific literature on expertise. The phrase “experimental philosophy” can mean many things. (shrink)

The perennial question posed by the philosophically-inclined lawyer is 'What is law?' or perhaps 'What is the nature of law?' This book poses an associated, but no less fundamental, question about law which has received much less attention in the legal literature. It is: 'Who is law for?' Whenever people go to law, they are judged for their suitability as legal persons. They are given or refused rights and duties on the basis of ideas about who matters. These ideas are (...) basic to legal-decision making; they form the intellectual and moral underpinning of legal thought. They help to determine whether law is essentially for rational human beings or whether it also speaks to and for human infants, adults with impaired reasoning, the comotose, foetuses and even animals. Are these the right kind of beings to enter legal relationships and so become legal persons. Are they, for example, sufficiently rational, or sacred or simply human? Is law meant for them? This book reveals and evaluates the type of thinking that goes into these fundamental legal and metaphysical determinations about who should be capable of bearing legal rights and duties. It identifies and analyses four influential ways of thinking about law's person, each with its own metaphysical suppositions. One approach derives from rationalist philosophy, a second from religion, a third from evolutionary biology while the fourth is strictly legalistic and so endeavours to eschew metaphysics altogether. The book offers a clear, coherent and critical account of these complex moral and intellectual processes entailed in the making of legal persons. (shrink)

Jacques Rancière: An Introduction offers the first comprehensive introduction to the thought of one of today's most important and influential theorists. Joseph Tanke situates Rancière's distinctive approach against the backdrop of Continental philosophy and extends his insights into current discussions of art and politics. Tanke explains how Rancière's ideas allow us to understand art as having a deeper social role than is customarily assigned to it, as well as how political opposition can be revitalized. The book presents Rancière's body (...) of work as a coherent whole, tracing key notions such as the distribution of the sensible, the aesthetics of politics, and the supposition of equality from his earliest writings through to his most recent interventions. Tanke concludes with a series of critical questions for Rancière's work, indicating how contemporary thought might proceed after its encounter with him. The book provides readers new to Rancière with a clear overview of his enormous intellectual output. Engaging with many un-translated and unpublished sources, the book will also be of interest to Rancière's long-time readers. (shrink)

Just as religion is impassable to its own dogmatic philosophies and ideas, present day science also acts in the same manner. Embracing its reductionist approach, it loses its sight to the most beautiful and insightful possibilities associated with the cosmos and its fundamental constituents around us. The present paper is a holistic ride into few of life’s beautiful constructs that occur as a playful act of the cosmos, and in part hypothesize that the dynamic biological structures or forms could be (...) thought of as frozen energy patterns. Here, the supposition is that the electromagnetic fields that envelop our ecosystems play a central role in its functioning and evolution acting as a unified network interconnecting life at various scales. Supporting a synergetic and holistic view, the present paper is skeptical about the present school of thought, and to other investigations carried out under the sheath of modern science by raising a few fundamental questions.

Several features of cosmology are of striking philosophical interest. Unlike other branches of physics which deal with kinds of occurrences and relations, cosmology investigates only one unique entity, the physical universe. Hence the science cannot avail itself of standard inductive procedures which depend on the assembling of samples. Cosmologists are therefore obliged to choose between two other procedures. Mr. Bondi calls them the "extrapolative" and the "axiomatic-deductive" lines of thought. The former starts from physical laws known to hold of (...) terrestrial or near-terrestrial phenomena. It then tries to frame an answer to the question: "What is the largest set of phenomena to which these laws can be applied consistently and successfully?" The result of this approach has been the construction of a number of "models" of the universe at large, each patterned on verified laws of physics. The axiomatic-deductive approach starts from certain a priori assumptions which are held to underlie any physical science whatever and which are equivalent to certain suppositions about the structure of the universe. From these assumptions, together with special axioms adopted for the purpose, the laws of cosmology are deduced. Then the deductions are checked with the observational data. Here again, various models of the cosmos have resulted. (shrink)

As a high school student, I rediscovered Hume’s problem of induction on my own. For a while, I was horrified. I thought, “We cannot know anything!” After a couple of weeks I calmed down and reasoned that there had to be something wrong with my thinking, and that led me quickly to the realization that good reasons need not be deductive, and to the discovery of defeasible reasoning. From there it was a short jump to a more general interest (...) in how rational cognition works. I am interested in rational cognition in general. Epistemology is one constituent of rational cognition, practical cognition (rational decision making) another. Much of the work on rational cognition begins with the supposition that only ideal agents can be truly rational. Real agents have limited powers of reasoning and limited memory capacity. It is often supposed that such resource-bounded agents can only approximate rationality, and that as philosophers we should confine our attention to ideal agents. If one wishes, one can of course define “rationality” in this way, but this has never been what interested me. We come to philosophy wondering what we should believe, what we should do, and how we should go about deciding these matters. These are questions about ourselves, with all of our cognitive limitations. For example, it is often claimed that ideal agents, with unlimited cognitive powers, should believe all of the logical consequences of their beliefs. But we, as real resource-bounded agents, cannot do that, so that is not something we should do. What I want to know is how I, as a real agent, should go about deciding what to believe and what to do. Thus my topic is real rationality as opposed to ideal rationality. In the realm of practical decision making, I have explored this distinction at great length in my recent book (2006). Here I will focus on its implications for epistemology. For many years epistemology was derailed by the Gettier problem.. (shrink)

In recent years, there has been a renewed interest in Perceptual Intuitionism. A significant portion of the literature on the topic has focused on the ethical perception defense, the supposition seeming to be that one must defend Perceptual Intuitionism by showing that one can have ethical experiences which immediately and non-inferentially justify one’s beliefs about the rightness or wrongness of particular actions. This thesis rejects this thought by proposing an alternative defense of Perceptual Intuitionism which employs the Wittgensteinian concept (...) of criteria and an understanding of principles of prima facie duties as “grammatical propositions”.

The problem of mortality treats death as posing a paradox for the narrative view of the self. This view, on some interpretations, needs death in order to complete a life in a manner analogous to the ending of a story. But death is inaccessible to the subject herself, and so the analogy fails. Our inability to grasp the event of our own death is thought to undermine the possibility of achieving a meaningful, coherent, or complete life on narrativist terms. (...) Narrativist attempts to solve the problem of mortality often involve exercises in "learning to be dead" in an effort to demonstrate that one's death is not entirely outside one's grasp. But there are different versions of the problem of mortality, which invite disparate solutions. I argue that most versions do not in fact pose a significant conundrum for the narrative view of the self. In order to strike at the narrative view in particular, in a fashion that is significant and a form that is paradoxical, a quite specific type of death must be at issue--one that is sudden and unanticipated. But a suggested solution to this version of the problem of mortality implies that the problem can be dissolved by disavowing certain alleged narrative presuppositions that fuel it. Those suppositions may, in turn, be essential to sustaining a uniquely narrative outlook on life and death. (shrink)

At the turn of the century Martin Buber arrived on the philosophic scene... The path to his maturity was one long struggle with the problem of unity- in particular with the problem of the unity of spirit and life; and he saw the problem itself to be rooted in the supposition of the primacy of the subject-object relation, with subjects "over here," objects "over there," and their relation a matter of subjects "taking in" objects or, alternatively, constituting them. But Buber (...) moved into a position which undercuts the subject-object dichotomy and initiates a second "Copernican revolution" in philosophical thought. (shrink)

Despite the hadiths and narratives that warn about the interpretation of the Qur’ān by opinion, the question of how Qur’ānic verses can be understood is about the nature of Qur’ānic exegesis. These narratives, which limit the interpretation to the exact field and indicate the invalidity of the specification of the intention with the imprecise information, bring with it the question of how to understand the Qur’ān in each period and society. The issue that has been questioned in the frame of (...) the commentary from the earliest periods is based on the possibility of commenting besides the narration and defining the area that the thought belongs to the commentator. In this context, it is seen that the distinction between the conceptualization of tafsīr-taʾwīl words in classical commentary literature deals with the subject of the tafsīr, their belongings, epistemological values and contexts. Mainly, this study will question whether authors who do not distinguish between tafsīr-taʾwīl categorize the information about commentary in a different context, then it will analyze two basic approaches on tafsīr and taʾwīl. In the paper, it will be suggested that these classifications in the classical literature should be evaluated together within the framework of the search for methodology in exegesis. Summary: The Prophet, who was the first glossator of the Qur’ān, forbade people to talk about the Qur’ān with their own judgments. The prominent people of the companions refused to comment on some words that were closed in meaning (garīb). The words quoted from Abū Bakr and ʿUmar on this subject are quite famous. However, the Qur’ān is a universal book revealed to be understood in all ages and geographies till the doomsday. The fact that all the verses were not interpreted by the Prophet, and the expansions of meaning observed in the Qur’ān wording necessitate the interpretation of the Qur’ān. The fact that the Prophet forbade people to talk with their own judgments about the Qur’ān and the necessity of understanding the Qur’ān in every era constitutes a dilemma that must be explained. The resolution of this issue will both determine the legitimacy of tafsīr (interpretation) and reveal the difference between the Prophet's tafsīr and the tafsīrs by other people. In this context, a distinction was made between the interpretations of the Prophet and of the companions who witnessed the revelation period from the Tabarī (d. 310/923) in the classical tafsīr literature and the interpretations by glossators in terms of their bindingness and information values. Thus, before even starting the interpretation, glossators questioned the possibility of interpretation of the Qur’ān without the tafsīr of the Prophet and the narratives from the companions that have the force of hadith marfūʿ.It is seen in classical tafsīr literature that distinctions between the tafsīr of the Prophet and the interpretations of the glossator are usually constructed on the terms of tafsīr and ta'wil, to which terminological meanings are attributed. In this regard, the methodology of Māturīdī (d. 333/944) is quite specific and clear. According to Māturīdī, tafsīr is an exact field. Only the tafsīr of the Prophet and the narratives of the companions that have the force of marfūʿ can be included in this field. Taʾwīl, on the other hand, is an area based on supposing. Preferences to be made from possible meanings are supposition and related to taʾwīl. The fact that Māturīdī included the explanations of the Prophet and his companions in the tafsīr field and stated that they expressed exact information shows that he regarded this information in the value of the statement of mutakallim. The data included in the field of taʾwīl are not as the data included in the field of tafsīr in terms of their bindingness and information value. The interpretations made in the field of taʾwīl include supposition; so they cannot be attributed to the desire of God. The field that the Prophet forbade people from declaring their own views is the field of tafsīr in the methodology of Māturīdī. The exactness of this field is an indication that the tafsīr is related to God's desire. It is not right to declare an opinion with supposition in the field that is exact and definite. Even though the interpretation in the field of tafsīr is in accordance with the truth, this cannot eliminate the responsibility of the interpreter that make determinations based on supposition in the exact and definite field. Some scholars, such as Qushayrī (d. 465/1072), also classify the narrative-sagacity areas by means of tafsīr-taʾwīl concepts. This classification deals with the data that is the subject of tafsīr in terms of their belongingness. Indeed, tafsīr science includes both the data that are linked with transmission and non-transmittable elements that can be achieved by following a methodology. Non-transmittable elements included in the taʾwīl field by those who make a distinction between tafsīr and taʾwīl based on narrative-sagacity are the meanings reached through linguistic efforts. Language is an element that holds possibilities in itself. Considering closeness of meaning, multi-meanings, metaphors and allusions in the wording, it can be thought that the meanings reached by linguistic methods include supposition. In the methodology of Māturīdī, the field of tafsīr is composed of the explanations of the Prophet and the narratives of the companions who witnessed the revelations while in the classifications of those who make a distinction between tafsīr and taʾwīl based on narrative-sagacity, tafsīr generally includes narratives. When the issue is handled within the framework of the desire of God and the statements of the mutakallim, it seems that the classification of Māturīdī is more punctual. However, it is understood that this approach does not give a satisfactory answer to the subsequent situations and bindingness of the mentioned data. In the classifications based on narrative-sagacity, the narratives in the field of tafsīr are taken as a whole without analyzing their health grades and their signification. However, some of these narrations are not authentic; so, in this respect it is a problematic issue that they are the subjects of the field of tafsīr. Besides, sometimes there can be different narrations about the tafsīr of verses from the companions. The evaluation these narratives in a field attributed to the desire of God may also pose a problem. The linguistic data that both Māturīdī and those who make a distinction between tafsīr and taʾwīl based on narrative-sagacity include in the field of taʾwīl does not appear to have a homogeneous structure -as is the case with the narratives-. Indeed, among this data, there are elements whose meanings are quite hard to determine as well as firm ones that possibly have only one meaning. It is controversial that these expressions, which have only one meaning and to the validity of whose meaning other evidence point out are included in the field of taʾwīl.The distinction between meaning and interpretation fields in tafsīr is very important in terms of tafsīr methodology. This field designation is in a way a description of nature of the science of tafsīr. Thus, in matters where the human intelligence remains insufficient with the tafsīr narratives from the Prophet, the bindingness of the narratives from the companions are clarified; furthermore, beyond the narrative, the validity and the information values of interpretations of the glossator are determined. In this regard, the tafsīr-taʾwīl distinctions made in the classical tafsīr literature provide us with a rich content and a multifaceted point of view. However, when addressed separately, these distinctions present a number of problems in terms of scope and applicability. Our study proposes the evaluation of tafsīr-taʾwīl distinctions in classical literature together while the meaning-interpretation fields are specified in the framework of the search for methodology in tafsīr. Thus, the incomplete aspects of the classification will be eliminated and a much more comprehensive and functional classification will be achieved. At this point, the methodologies of some figures as Tabarī, who is known to have used the terms of tafsīr and taʾwīl in the same meaning, must also be evaluated separately. Indeed, when the works of these names are analyzed, it is seen that these names also distinguish the meaning-interpretation fields in tafsīr, but they do not do this through the tafsīr-taʾwīl concepts.

My topic is how to make decisions when you possess foreknowledge of the consequences of your choice. Many have thought that these kinds of decisions pose a distinctive and novel problem for causal decision theory (CDT). My thesis is that foreknowledge poses no new problems for CDT. Some of the purported problems are not problems. Others are problems, but they are not problems for CDT. Rather, they are problems for our theories of subjunctive supposition. Others are problems, but they (...) are not new problems. They are old problems transposed into a new key. Nonetheless, decisions made with foreknowledge illustrate important lessons about the instrumental value of our choices. Once we've appreciated these lessons, we are left with a version of CDT which faces no novel threats from foreknowledge. (shrink)

It is often thought that the test for whether an indicative conditional is assertible is to first suppose the antecedent and then check to see if the consequent is probable on that supposition. Call this procedure the “Ramsey Test”. Some influential accounts of indicative conditionals hold that the Ramsey Test works because indicative conditionals are used to express a high credence in the consequent conditional on the antecedent. In this paper I will argue that a different expressivist account, one (...) inspired by Brandom can handle a wider range of phenomena. In particular, it does a better job explaining how conditionals function in modus tollens arguments. I will end by discussing how the account proposed here goes beyond Brandom’s own work on logic and hermeneutics. Of particular importance is the role played by a conversational common ground, distinct from the commitments of the interpreter and interpreted. (shrink)

I develop and defend the view that subjects are necessarily psychologically able to revise their beliefs in response to relevant counter-evidence. Specifically, subjects can revise their beliefs in response to relevant counter-evidence, given their current psychological mechanisms and skills. If a subject lacks this ability, then the mental state in question is not a belief, though it may be some other kind of cognitive attitude, such as a supposition, an entertained thought, or a pretense. The result is a moderately (...) revisionary view of belief: while most mental states we thought were beliefs are beliefs, some mental states which we thought were beliefs are not beliefs. The argument for this view draws on two key claims: First, subjects are rationally obligated to revise their beliefs in response to relevant counter-evidence. Second, if some subject is rationally obligated to revise one of her mental states, then that subject can revise that mental state, given her current psychological mechanisms and skills. Along the way to defending these claims, I argue that rational obligations can govern activities which reflect on one’s rational character, whether or not those activities are under one’s voluntary control. I also show how the relevant version of epistemic ‘ought’ implies ‘can’ survives an objection which plagues other variants of the principle. (shrink)

This paper is an attempt to rethink from two perspectives Buridan’s ideas concerning knowledge: On the one hand, I explore Buridan’s theory of knowledge in the hope that it will shed some light on the intuition that the structure of propositions determines the justification of our beliefs on various different levels. On the other hand, I would like to contribute to demonstrating the consistency of Buridan’s thought,which has been remarked by almost all scholars working on Buridan: in particular, I (...) am interested in exploring the benefits of using supposition theory when applied to the theory of knowledge. I will start by examining Buridan’s conception of scientia (as opposed to error, opinio and fides), from the perspective of two distinctions which are very important to Buridan’s theory of the proposition: complexio/enunciatio and enunciatio/assensus. Then I will recall Buridan’s analysis of propositions (and his use of supposition to define truth conditions) to show their consistency with this conception of knowledge. (shrink)
