On the basis of evidence drawn from the Waste book, Westfall and Nicholas have argued that Newton arrived at his second law of motion by reflecting on the implications of the first law. I analyze another argument in the Waste book which reveals that Newton also arrived at the second law by another very different route. On this route, it is the consideration of the third law and the principle of conservation of motion—and not the first law—that prompts (...) Newton to formulate the second law. The existence of these two routes is significant because each employs a distinct kind of reasoning about forces. Whereas the Nicholas–Westfall route via the principle of inertia bears the mark of Descartes’s influence, the alternative route proceeds from the action–reaction principle, which is widely regarded as an original Newtonian contribution to mechanics. In the course of exploring this alternate route to the second law, the origins and justification of the third law are examined.Keywords: Issac Newton; Waste book; Third law of motion; Second law of motion; Richard Westfall; John Nicholas.

Presents Newton's unifying idea of gravitation and explains how he converted physics from a science of explanation into a general mathematical system.

An introduction to the model-theoretic approach in the philosophy of science is given and it is argued that this program is further enhanced by the introduction of partial structures. It is then shown that this leads to a natural and intuitive account of both "iconic" and mathematical models and of the role of the former in science itself.

We apply the recently elaborated notions of ‘pragmatic truth’ and ‘pragmatic probability’ to the problem of the construction of a logic of inductive inference. It is argued that the system outlined here is able to overcome many of the objections usually levelled against such attempts. We claim, furthermore, that our view captures the essentially cumulative nature of science and allows us to explain why it is indeed reasonable to accept and believe in the conclusions reached by inductive inference.

Far from overthrowing or stepping outside that tradition, Wittgenstein builds on it, draws from it, and contributes brilliantly to the fruition of certain elements in it. In This Complicated Form of Life, Garver analyzes from several angles Wittgenstein's relationship to Kant, and to what Finch has called Wittgenstein's completion of Kant's revolt against the Cartesian hegemony of epistemology in philosophy.

The Mathematical Principles of Natural Philosophy.

Our purpose in this paper is to delineate an ontology for quantum mechanics that results adequate to the formalism of the theory. We will restrict our aim to the search of an ontology that expresses the conceptual content of the recently proposed modal-Hamiltonian interpretation, according to which the domain referred to by non-relativistic quantum mechanics is an ontology of properties. The usual strategy in the literature has been to focus on only one of the interpretive problems of the theory and (...) to design an interpretation to solve it, leaving aside the remaining difficulties. On the contrary, our aim in the present work is to formulate a “global” solution, according to which different problems can be adequately tackled in terms of a single ontology populated of properties, in which systems are bundles of properties. In particular, we will conceive indistinguishability between bundles as a relation derived from indistinguishability between properties, and we will show that states, when operating on combinations of indistinguishable bundles, act as if they were symmetric with no need of a symmetrization postulate.

Como pensar a ética a partir das contradições de um mundo que, no mesmo espaço e ao mesmo tempo, produz uma ciência e intelectuais dedicados a pesquisar princípios de vida e armas de morte; progressos nas comunicações e mecanismos sutis e aberrantes de censura? Eis as questões: falso bem, falsa justiça, falsa liberdade, falsa virtude, que, ao criarem o homem da concórdia, da submissão e da boa-fé, o tornam duas vezes escravo: da superstição e das convenções. Os textos que compõem (...) essa obra, originalmente produzidos para o curso livre Ética, procuram, assim, pensar as razões pelas quais os homens se comportam de determinada maneira e por que a maioria das doutrinas morais conserva vestígios da servidão, no momento mesmo em que promete instaurar a liberdade.ÍndiceCenários - Adauto NovaesA tragédia grega e o humano - Nicole LorauxHumanidade e justiça na historiografia grega, V-I a.

How aggressively should we pursue life-sustaining treatment of the demented patient? This question becomes increasingly important as our population ages and medical technology offers ever more life-prolongation. In Life'sDominion, Ronald Dworkin addresses the issue in the context of an Alzheimer patient who had previously declared the desire to avoid life-sustaining intervention. Dworkin argues for the primacy of what he calls precedent autonomy: In 1995, the HastingsCenterReport carried thoughtful rebuttals by Daniel Callahan and Rebecca Dresser. Much of Callahan's article is devoted (...) to patients who never executed an advance directive, but he states unequivocally that such directives can be overridden, basing much of his argument on the writings of Sanford Kadish. Together, Dresser, Callahan, and Kadish define a clear position opposed to precedent autonomy. (shrink)

Aside from the Principia and occasional appearances of the Opticks , Newton' writings have remained largely inaccessible to students of philosophy, science, and literature as well as to other readers. This book provides a remedy with wide representation of the interests, problems, and diverse philosophic issues that preoccupied the greatest scientific mind of the seventeenth century. Grouped in sections corresponding to methods, principles, and theological considerations, these selections feature explanatory notes and cross-references to related essays.
