Aristotle's Physics is a work of extraordinary intellectual power which has had a profound influence on scientists and philosophers throughout the ages, and on the development of physics itself. This collection of major, previously unpublished, essays by leading Aristotelian scholars examines a wide range of major issues in the Physics and other related works. They offer fresh approaches to Aristotle's work and important new interpretations of his thought.

On the basis of what Aristotle says in the Posterior Analytics about how sciences are differentiated and about the impermissibility of ‘kind-crossing’, many commentators suppose that when it comes to his scientific practice, Aristotle treats the boundaries of the sciences as impermeable, so that if subject-matter X is the business of one science, it simply cannot be the business of another. I call this the impermeable boundary theory of the sciences: knowledge is divided into watertight compartments, determined by their distinct (...) genera, and what goes on in one compartment cannot turn up in another. I argue that, even if this is a correct account of Aristotle’s position in the Analytics, the view that he accepts the impermeable boundary theory when it comes to his scientific and philosophical work outside the Analytics is simply untenable.

Lambda, the twelfth book of Aristotle's Metaphysics, is an outline for a much more extended work in metaphysics or, more accurately, in what Aristotle calls 'first philosophy', the inquiry into 'the principles and causes of all things'. Lindsay Judson provides a rigorous translation of this important book and a detailed philosophical commentary.

Lindsay Judson and Vassilis Karasmanis present a selection of philosophical papers by an outstanding international team of scholars, assessing the legacy and continuing relevance of Socrates's thought 2,400 years after his death. The topics of the papers include Socratic method; the notion of definition; Socrates's intellectualist conception of ethics; famous arguments in the Euthyphro and Crito; and aspects of the later portrayal and reception of Socrates as a philosophical and ethical exemplar, by Plato, the Sceptics, and in the (...) early Christian era. Contributors include Lesley Brown, David Charles, John Cooper, Michael Frede, Terence Irwin, Charles Kahn, Vassilis Karasmanis, Carlo Natali, Vasilis Politis, Dory Scaltsas, Gerhard Seel, and C. C. W. Taylor. (shrink)

I argue that Metaphysicsλ‎ is a unified work, and one which is not a continuation of the central books ΖΗΘ‎. It outlines an extensive project in First Philosophy, which has close connections with ΑΒΓΕ‎, but which proceeds on a different trajectory from ΖΗ‎. The principal problem in understanding λ‎ as a whole is how to reconcile Aristotle's explicit presentation of the book as a highly unified study with the disparate character of its two halves – the first a general‐metaphysical enquiry (...) into the features which changeable substances have as being substances of that kind, the second a detailed investigation of the specific character and activity of immaterial substances. My paper aims to show how this reconciliation is possible, and what we can learn about Aristotle's conception of first philosophy as a result. (shrink)

The standard interpretation of this passage sees Aristotle as claiming that if a thing is F eternally, its being F is not the exercise of any potentiality to be F, and as explicitly applying this claim to the heavenly bodies. This interpretation faces a number of difficulties: I shall offer a different reading which avoids these, and which brings out interesting connections between this passage and some arguments in Λ.6-7.

Aristotle usually has an extremely bad reputation as a physicist among scientists and historians of science. Central to this is the treatment of his version of the geocentric conception of the cosmos, according to which the earth is at the centre of the cosmos and does not move, and which was the dominant picture in antiquity and throughout the middle ages. Aristotle’s view is commonly regarded as a pernicious influence on the course of cosmology until the Renaissance, one which held (...) sway only because of Aristotle’s authority. The chapter argues that his integration of astronomy and physics—his pursuit, in a variety of works written over a long period, of the question: ‘what does the world have to be like, in terms of a unified physics, if current astronomical theory is right?’—embodies a degree of comprehensiveness, sophistication, and elegance simply unparalleled in the ancient world. It is also more robust—given the astronomy of Aristotle’s day—than is usually thought: the chapter considers a number of difficulties it faced, and outlines responses which Aristotle either did make or could have made. The only serious rival to Aristotle’s astrophysics before Kepler and Newton was the theory set out in Ptolemy’s Planetary Hypotheses, which attempts to integrate physics with his astronomy: the chapter argues that for all its subtlety, this theory fares very poorly as a piece of physics. It was not, therefore, simple deference to authority which led some Islamic and Renaissance scientists to prefer Aristotle’s theory even though they could not see how to square it with Ptolemaic astronomy.

This paper argues that the discussion in which Aristotle engages in Metaphysics ΖΗ has the same starting-point as natural science: the principles of changing substances. These inquiries are nonetheless distinct because natural science uses these principles in its detailed investigations into natural substances, whereas ΖΗ reflect on the principles themselves. ΖΗ are an integral part of Aristotle’s inquiry into the principles of all substances, changing and unchanging: they are not merely preliminary to an inquiry into the latter kind. They are (...) also an integral part of Aristotle’s ‘first philosophy’, alongside theology’s study of the nature and activity of unchanging substances. (shrink)

I investigate the epistemic status of the hypotheses and other premises used in Socrates’ ‘arguments from a hypothesis’ in the Meno, and of the conclusions drawn from them, and argue that, while they are taken by Socrates to fall short of knowledge, he takes them all to have a positive epistemic status, and is not committed to advancing them only tentatively.

Available from UMI in association with The British Library. Requires signed TDF. ; Aristotle endorses a very striking doctrine connecting necessity with what seems to be a non-modal notion--that of 'being or happening always'. He also forges a connection between the idea of 'happening by chance' and 'happening neither always nor for the most part'. These two connections form the subject of this essay. My guiding aim is to provide an account of what the 'always/necessary' doctrine involves and of why (...) Aristotle might have held it. Reflection on the nature of the connection between 'by chance' and 'neither always nor for the most part' throws light on what Aristotle means by 'happening always', and, in consequence, on the nature of the link between 'always' and 'necessary'; it also suggests that the basis of this link is to be found in Aristotle 's general conception of the natural world as the object of explanation and knowledge. ;The primary texts upon which discussion of these connections must focus are De Caelo I. 12 and the analysis of chance in Physics II. 4-6. I discuss these two texts in turn, after an opening chapter which surveys the evidence for Aristotle 's acceptance of the 'always/necessary' doctrine and considers the nature of the restrictions which he places on it. Chapter 2 comprises a translation of and commentary on Cael. I. 12, together with a translation and discussion of its companion chapter, I. 10. In Chapter 3, I examine the nature of Aristotle 's argument in I. 12, and criticise various interpretations which see it as evidence that Aristotle 's 'always/necessary' doctrine rests on a distinctive conception of possibility. The translation of and commentary on Phys. II. 4-6 are followed in Chapter 5 by a discussion of issues relating to the association of chance with 'neither always nor for the most part'. The final chapter returns to the question of the connection between 'always' and 'of necessity'. (shrink)

A Review of Lindsay Judson and Vassilis Karasmanis , Remembering Socrates: Philosophical Essays, Clarendon Press, Oxford, 2006.

The concept of self-motion is not only fundamental in Aristotle's argument for the Prime Mover and in ancient and medieval theories of nature, but it is also central to many theories of human agency and moral responsibility. In this collection of mostly new essays, scholars of classical, Hellenistic, medieval, and early modern philosophy and science explore the question of whether or not there are such things as self-movers, and if so, what their self-motion consists in. They trace the development of (...) the concept of self-motion from its formulation in Aristotle's metaphysics, cosmology, and philosophy of nature through two millennia of philosophical, religious, and scientific thought. This volume contains "Self-Movers" (David Furley), "Aristotle on Self-Motion" (Mary Louise Gill), "Aristotle on Perception, Appetition, and Self-Motion" (Cynthia Freeland), "Self-Movement and External Causation" (Susan Sauvé Meyer), "Aristotle on the Mind's Self-Motion" (Michael Wedin), "Mind and Motion in Aristotle" (Christopher Shields), "Aristotle's Prime Mover" (Aryeh Kosman), "The Transcendence of the Prime Mover" (Lindsay Judson), "Self-Motion in Stoic Philosophy" (David Hahm), "Duns Scotus on the Reality of Self-Change" (Peter King), "Ockham, Self-Motion, and the Will" (Calvin Normore), and "Natural Motion and Its Causes: Newton on the 'Vis Insita' of Bodies" (J. E. McGuire). Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

According to the theory Russell defends in The Analysis of Mind, ‘true memories’ (roughly, memories that are not remembering-hows) are recollections of past events accompanied by a feeling of familiarity. While memory images play a vital role in this account, Russell does not pay much attention to the fact that imagery plays different roles in different sorts of memory. In most cases that Russell considers, memory is based on an image that serves as a datum (imagebased memories), but there are (...) other cases in which memory judgment requires an image without being based on it (answer-memories). A good example for the former is when a person, asked what the colour of the sea was last afternoon, recalls an image and forms a judgment on this basis. In the second case she may recognize the sea and entertain a memory image of it without ‘reading off’ the memory judgment from this picture. That is, the image does not prompt but itself is part of the propositional content of answer memories. Since in this latter case the feeling of familiarity is constitutive of the recollection but cannot serve as its explanans, answer memories do not conform to Russell’s account. According to Lindsay Judson this is not a vice of the theory, since Russell never meant to extend it to answer memories. Despite having a certain appeal of benevolence, Judson’s interpretation is not supported by textual evidence. Taking side with David Pears, I will argue that Russell did not properly differentiate between image-based memory and answer memory, and illegitimately extended his theory to the latter. (shrink)

In this paper I articulate a view of doxastic control that helps defend the legitimacy of our practice of blaming people for their beliefs. I distinguish between three types of doxastic control: intention-based, reason-based, and influence-based. First I argue that, although we lack direct intention-based control over our beliefs, such control is not necessary for legitimate doxastic blame. Second, I suggest that we distinguish two types of reason-responsiveness: sensitivity to reasons and appreciation of reasons. I argue that while both capacities (...) are necessary for satisfying the control condition, neither is sufficient. Finally, I defend an influence-based view of doxastic control according to which we have the capacity to execute intentions to engage in reflection that causally influences our beliefs in positive epistemic ways. This capacity is both necessary and sufficient for satisfying the control condition for legitimate doxastic blame. I end by defending the view from two objections: that reflection is not necessary for meeting the control condition, and that it is not sufficient. (shrink)

This book grew out of a graduate student paper [261] in which I set down some criticisms of J. R. Lucas' attempt to refute mechanism by means of G6del's theorem. I had made several such abortive attempts myself and had become familiar with their pitfalls, and especially with the double edged nature of incompleteness arguments. My original idea was to model the refutation of mechanism on the almost universally accepted G6delian refutation of Hilbert's formalism, but I kept getting stuck on (...) questions of mathematical philosophy which I found myself having to beg. A thorough study of the foundational works of Hilbert and Bernays finally convinced me that I had all too naively and uncritically bought this refutation of formalism. I did indeed discover points of surprisingly close contact between formalism and mechanism, but also that it was possible to under mine certain strong arguments against these positions precisely by invok ing G6del's and related work. I also began to realize that the Church Turing thesis itself is the principal bastion protecting mechanism, and that G6del's work was perhaps the best thing that ever happened to both mechanism and formalism. I pushed these lines of argument in my dis sertation with the patient help of my readers, Raymond Nelson and Howard Stein. I would especially like to thank the latter for many valuable criticisms of my dissertation as well as some helpful suggestions for reor ganizing it in the direction of the present book. (shrink)

Husserl’s first work formulated what proved to be an algorithmically complete arithmetic, lending mathematical clarity to Kronecker’s reduction of analysis to finite calculations with integers. Husserl’s critique of his nominalism led him to seek a philosophical justification of successful applications of symbolic arithmetic to nature, providing insight into the “wonderful affinity” between our mathematical thoughts and things without invoking a pre-established harmony. For this, Husserl develops a purely descriptive phenomenology for which he found inspiration in Mach’s proposal of a “universal (...) physical phenomenology.” To account for applications to any domain, Husserl envisages a theory of all possible deductive systems, which he develops extensively in his Göttingen lectures wherein he engages with Hilbert’s work on deductive systems for geometry, real arithmetic, and physics. This leads Husserl to formulate claims of decidability and proofs of completeness for various arithmetics that result from his analysis of Kronecker’s general arithmetic. Careful attention to these proofs seem to show that Husserl was not oblivious to problems that underlie our incompleteness theorems, namely that of showing that some inversions of his algorithmic arithmetic are undefined. His growing preoccupation with the issue of a pre-established harmony between mathematical thought and reality motivate his pursuit of a “supramathematics” of all possible complete theory forms to demystify such harmony, by having such a form on hand for describing any empirical domain. He soon decides that a transcendental idealism of nature will reveal the wonderful affinity of thoughts and things comprising such harmony, to be a wonderful “parallelism of objective unities and constituted manifolds of consciousness.” But the paradoxes of logic and set theory cloud the clarity of mathematics, which Weyl would restore with Brouwer’s intuitionism and Hilbert with his metamathematics. Husserl informed Weyl that his student Becker had formulated a phenomenological foundation not only for Weyl’s generalization of relativity theory but also for the Brouwer-Weyl continuum. But Weyl eventually rejected much of Becker’s work, especially when it became clear that his phenomenological intuitionism could not account for the success of Hilbert’s transfinite mathematics in quantum physics. Becker responded to this “crisis of phenomenological method” with his mantic phenomenology celebrating the magic of mathematical mysticism, which Husserl finally rejects in favor of a pluralistic phenomenology of mathematics and nature.

The metamathematical theorems of Gödel and Church are frequently applied to the philosophy of mind, typically as rational evidence against mechanism. Using methods of Post and Smullyan, these results are presented as purely mathematical theorems and various such applications are discussed critically. In particular, J. Lucas's use of Gödel's theorem to distinguish between conscious and unconscious beings is refuted, while more generally, attempts to extract philosophy from metamathematics are shown to involve only dramatizations of the constructivity problem in foundations. More (...) specifically, philosophical extrapolations from metamathematics are shown to involve premature extensions of Church's thesis. (shrink)

This paper seeks to answer the question: Can contemporary forms of artificial intelligence be creative? To answer this question, I consider three conditions that are commonly taken to be necessary for creativity. These are novelty, value, and agency. I argue that while contemporary AI models may have a claim to novelty and value, they cannot satisfy the kind of agency condition required for creativity. From this discussion, a new condition for creativity emerges. Creativity requires curiosity, a motivation to pursue epistemic (...) goods. I argue that contemporary AI models do not satisfy this new condition. Because they lack both agency and curiosity, it is a mistake to attribute the same sort of creativity to AI that we prize in humans. Finally, I consider the question of whether these AI models stand to make human creativity in the arts and sciences obsolete, despite not being creative themselves. I argue, optimistically, that this is unlikely. (shrink)
