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.

We must all make choices about how we want to live. We evaluate our possibilities by relying on historical, moral, personal, political, religious, and scientific modes of evaluations, but the values and reasons that follow from them conflict. Philosophical problems are forced on us when we try to cope with such conflicts. There are reasons for and against all proposed ways of coping with the conflicts, but none of them has been generally accepted by reasonable thinkers. The constructive aim of The Nature of Philosophical Problems is to propose a way of understanding the nature of such philosophical problems, explain why they occur, why they are perennial, and propose a pluralist approach as the most reasonable way of coping with them. This approach is practical, context-dependent, and particular. It follows from it that the recurrence of philosophical problems is not a defect, but a welcome consequence of the richness of our modes of understanding that enlarges the range of possibilities by which we might choose to live. The critical aim of the book is to give reasons against both the absolutist attempt to find an overriding value or principle for resolving philosophical problems and of the relativist claim that reasons unavoidably come to an end and how we want to live is ultimately a matter of personal preference, not of reasons.

Daniel Stoljar presents a persuasive rejection of the widespread view that philosophy makes no progress. He defends a reasonable optimism about philosophical progress, showing that we have correctly answered philosophical questions in the past and may expect to do so in the future. He offers a credible vision of how philosophy works.

I. MASS TERMS, COUNT TERMS, AND SORTAL TERMS Central examples of mass terms are easy to come by. 'Water', 'smoke', 'gold', etc. , differ in their syntactic, semantic, and pragmatic properties from count terms such as 'man', 'star', 'wastebasket', etc. Syntactically, it seems, mass terms do, but singular count terms do not, admit the quantifier phrases 'much', 'an amount of', 'a little', etc. The typical indefinite article for them is 'some' (unstressed)!, and this article cannot be used with singular count terms. Count terms, but not mass terms, use the quantifiers 'each', 'every', 'some', 'few', 'many'; and they use 'a(n)' as the indefinite article. They can, unlike the mass terms, take numerals as prefixes. Mass terms seem not to have a plural. Semantically, philo sophers have characterized count terms as denoting (classes of?) indi vidual objects, whereas what mass terms denote are cumulative and dissective. (That is, a mass term is supposed to be true of any sum of things (stuff) it is true of, and true of any part of anything of which it is true). Pragmatically, it seems that speakers use count terms when they wish to refer to individual objects, or when they wish to reidentify a particular already introduced into discoursc. Given a "space appropriate" to a count term C, it makes sense to ask how many C's there are in that space.

This volume focuses on philosophical problems concerning sense perception in the history of philosophy. It consists of thirteen essays that analyse the philosophical tradition originating in Aristotle’s writings. Each essay tackles a particular problem that tests the limits of Aristotle’s theory of perception and develops it in new directions. The problems discussed range from simultaneous perception to causality in perception, from the representational nature of sense-objects to the role of conscious attention, and from the physical/mental divide to perception as quasi-rational judgement. The volume gives an equal footing to Greek, Arabic, and Latin philosophical traditions. It makes a substantial contribution not just to the study of the Aristotelian analysis of sense perception, but to its reception in the commentary tradition and beyond. Thus, the papers address developments in Alexander of Aphrodisias, Themistius, Avicenna, John of Jandun, Nicole Oresme, and Sayf al-Din al-Amidi, among others. The result of this is a coherent collection that attacks a well-defined topic from a wide range of perspectives and across philosophical traditions.

This richly detailed 1981 biography captures both the personal life and the scientific career of Isaac Newton, presenting a fully rounded picture of Newton the man, the scientist, the philosopher, the theologian, and the public figure. Professor Westfall treats all aspects of Newton's career, but his account centres on a full description of Newton's achievements in science. Thus the core of the work describes the development of the calculus, the experimentation that altered the direction of the science of optics, and especially the investigations in celestial dynamics that led to the law of universal gravitation.

Does philosophy have a timeless essence? Are the writings that have come down to us over the centuries from philosophers of genius mere souvenirs from a bygone era? Or are their thoughts still eminently worth examining with care? Modern Challenges to Past Philosophy argues pondering past philosophy with modern problems in mind is worth the effort, even though earlier works are uninformed by modern science and lack some of tools of modern analysis. The great texts defamiliarize our world and offer solutions to crucial questions often forgotten as we fixate on current philosophical trends. Modern Challenges is no appeal to a return to a golden past but a study designed to show how and why understanding earlier works of some of the most penetrating minds ever to ponder eternally valid questions can contribute to a renewal of our own culture.
