Limits to Action: The Allocation of Individual Behavior presents the ideas and methods in the study of how individual organisms allocate their limited time and energy and the consequences of such allocation. The book is a survey of individual resource allocation, emphasizing the relationships of the concepts of utility, reinforcement, and Darwinian fitness. The chapters are arranged beginning with plants and general evolutionary considerations, through animal behavior in nature and laboratory, and ending with human behavior in suburb and institution. Topics (...) discussed include operant conditioning; the principle of diminishing returns; and issues in relation to mating strategies. Biologists, sociologists, economists, and psychologists will find the book interesting. (shrink)

What are physical quantities, and in particular, what makes them quantitative? This book presents an original answer to this question through the novel position of substantival structuralism, arguing that quantitativeness is an irreducible feature of attributes, and quantitative attributes are best understood as substantival structured spaces.

It may seem strange, in view of the spate of recent literature on the subject, that yet another article should be forthcoming on what is certainly the most familiar, as well as the most vexed, of all Platonic passages. But it is precisely this spate of literature that has impelled me to write. The time seems to have come for an article which, rather than seeking desperately for something new, sets out instead to reaffirm those facts and conclusions that even (...) the most resolutely original of scholars could hardly venture to dispute. This article will therefore be based, not on any of the numerous modern interpretations, but on what Plato himself actually wrote. It will contain a number of tentative suggestions which, to the best of my knowledge, have not been made before. They can, and probably will, be rejected. But its primary purpose remains to restate, whenever possible in Plato's own words, a number of important facts that are at once so simple and so obvious that they seem repeatedly, and especially in recent years, to have been quite forgotten.

This book is an anthology of Plato's writings, connected with sections of commentary.

It is standardly assumed that there are three — and only three — ways to solve problem of temporary intrinsics: (a) embrace presentism, (b) relativize property possession to times, or (c) accept the doctrine of temporal parts. The first two solutions are favoured by endurantists, whereas the third is the perdurantist solution of choice. In this paper, I argue that there is a further type of solution available to endurantists, one that not only avoids the usual costs, but is structurally (...) identical to the temporal-parts solution preferred by perdurantists. In addition to providing a general characterization of this new type of solution, I discuss certain of its anticipations in the literature on bundle theory, as well as provide a detailed development of it in terms of my own preferred metaphysics of ordinary objects — namely, a distinctive form of substratum theory tracing to Aristotle.

In a well-known quotation from Speusippus in the Theologumena Arithmeticae , said to have been derived from Pythagorean sources, especially Philolaus, occur the following sentences: And again a little later: Similarly Sextus Empiricus , drawing evidently on a relatively early Pythagorean source, writes as follows: And Aristotle himself writes of the Pythagoreans : There were, in fact, certain Pythagoreans who equated the number 2 with the line because they regarded the line as ‘length without breadth extended between two points’; and (...) likewise the number 3 was equated with the plane and 4 with the solid.

The subject is in both cases the voyage of the Argo, and therefore the use of the same words is not likely to be coincidental, even though the words themselves are scarcely uncommon. One would hesitate to deny, however, that such reminiscence might be unconscious; that Lucan had famous tags in his head is suggested by another allusion to famous opening lines.

No pre-Socratic philosopher, perhaps, has caused more disagreement, or been more variously interpreted, than Anaxagoras of Clazomenae. Among recent attempts to reconstruct his system some of the more notable are those of Tannery, Bailey, Cornford, Peck, and Vlastos. Each of these reconstructions, and especially that of Tannery, has its adherents; and since none of them has much in common with any other, a universally acceptable solution to the fundamental problems involved may well by now seem unattainable. It is my belief, (...) however, and it is the object of this paper to try to prove, that all these modern reconstructions have at least one quality in common, namely an undue complication. The actual system of Anaxagoras was, I believe, considerably simpler than any reconstruction yet forthcoming. Unfortunately what I take to be the basis of the whole system, Anaxagoras' reaction to his Eleatic predecessors, is by.no means easy to convey in brief and simple terms. But if I should succeed in conveying it, then it will, I hope, be seen in itself to possess such a simplicity and neatness that my contention will carry with it a fair warrant of its own truth. I shall, for convenience, divide my argument into ten sections, to which I shall append a brief summary of my conclusions. (shrink)

Manuscript Add. 3965, section 13, folios 541r–542r and 545r–546r is in the Portsmouth Collection of manuscripts and housed in the University Library, Cambridge. These drafts contain a careful account, in Newton's hand, of his views on place, time, and God. They are part of a large number of drafts relating to the three official editions of the Principia published in Newton's lifetime.

Recent literature on causation invokes a distinction between deviant and default behavior to account for token causation. Critical examination of two prominent attempts to employ a distinction between deviants and defaults reveals that the distinction is far from clear. I clarify and develop the distinction by appeal to the notion of a modally robust process, and show how the distinction can be employed by causal process theorists to respond to cases of causation by omission. This shows that the default/deviant distinction (...) is not so much a tool for counterfactual accounts of causation, but rather for causal process theory. (shrink)

This study considers Newton's views on space and time with respect to some important ontologies of substance in his period. Specifically, it deals in a philosophico-historical manner with his conception of substance, attribute, existence, to actuality and necessity. I show how Newton links these “features” of things to his conception of God's existence with respect of infinite space and time. Moreover, I argue that his ontology of space and time cannot be understood without fully appreciating how it relates to the (...) nature of Divine existence. In order to establish this, the ontology embodied in Newton's theory of predication is analysed, and shown to be different from the presuppositions of the ontological argument. From the historical point of view Gassendi's influence is stressed, via the mediation of Walter Charleton. Furthermore, Newton's thought on these matters is contrasted with Descartes's and Spinoza's. In point of fact, in his earliest notebook Newton recorded observations on Descartes's version of the ontological argument. Soon, however, he was to oppose the Cartesian conception of the actuality of Divine existence by means of arguments similar to those of Gassendi. Lastly, I suggest that the nature and extent of Henry More's influence on Newton's conception of how God relates to absolute space and time bears further examination. (shrink)

Isaac Newton wrote the manuscript Questiones quaedam philosophicae at the very beginning of his scientific career. This small notebook thus affords rare insight into the beginnings of Newton's thought and the foundations of his subsequent intellectual development. The Questiones contains a series of entries in Newton's hand that range over many topics in science, philosophy, psychology, theology, and the foundations of mathematics. These notes, written in English, provide a very detailed picture of Newton's early interests, and record his critical appraisal (...) of contemporary issues in natural philosophy. Written predominantly in 1664-5, they give a significant perspective on Newton's thought just prior to his annus mirabilis, 1666. This volume provides a complete transcription of the Questiones, together with an 'expansion' into modern English, and a full editorial commentary on the content and significance of the notebook in the development of Newton's thought. It will be essential reading for all those interested in Newton and the intellectual foundations of science. (shrink)

Although Professor of Philosophy at Calvin College, Alvin Plantinga has developed a theodicy that is fundamentally Arminian rather than Calvinistic. Anthony Flew, although the son of an Arminian Christian minister, regards the Arminian view of ‘free will’ to be both unacceptable on its own terms and incompatible with classical Christian theism. In this paper I hope to disentangle some of the involved controversy regarding theodicy which has developed between Plantinga and Flew, and between Flew and myself. The major portion of (...) this paper is devoted to showing that Plantinga's theodicy contains some serious flaws and undesirable implications. (shrink)

: This article is concerned with Newton's appropriation of Descartes' ontology of true and immutable natures in developing his theory of infinitely extended space. It contends that unless the part played by the Platonic distinction between "being a nature" and "having a nature" in Newton's thinking is properly appreciated the foundation of his doctrine of space in relation to God will not be fully understood. It also contends that Newton's Platonism is consistent with his empiricism once the mediating role is (...) made clear that the geometry of moving loci play in grounding his intuitions concerning infinite natures.

This essay explores the role of God’s omnipresence in Newton’s natural philosophy, with special emphasis placed on how God is related to space. Unlike Descartes’ conception, which denies the spatiality of God, or Gassendi and Charleton’s view, which regards God as completely whole in every part of space, it is argued that Newton accepts spatial extension as a basic aspect of God’s omnipresence. The historical background to Newton’s spatial ontology assumes a large part of our investigation, but with attention also (...) focused on the details of Newton’s unique approach to these traditional Scholastic conceptions.
