BAS VAN FRAASSEN LAWS AND SYMMETRY PDF

The historical role of the concept of a law of nature in medieval and early modern physics engendered a view of science as continuous with metaphysics, which has tended to dominate philosophy of nature and of science. Meanwhile, with the development of mathematical methods, the advanced sc This serves to provide content to a notion of physical necessity, but Induction has given way to Infere nce to the Best Explanation IBE in the epistemology hospitable to realism, or to metaphysics in general. Both Dretske and Armstrong provide severe critiques of traditional notions of Induction, and offer new foundations for inductive methods. This chapte

In Parts I and II I shall be concerned with the philosophical approach to science which has laws of nature as its central concern. After an initial discussion of criteria, Part I will focus on specific theories of laws of nature, recently proposed and defended. I shall argue that these theories face an insuperable dilemma -- of two problems whose solutions must interfere with each other -- which will occur for all theories of similar stripe.

Epistemological arguments to the effect that we must believe in the reality of laws regardless of such difficulties will be broached in Part II. Throughout I shall keep in view the main question: can this approach to science, which looks to such deep foundations, possibly be adequate to its subject?

Read preview. Synopsis Metaphysicians speak of laws of nature in terms of necessity and universality; scientists, in terms of symmetry and invariance.

In this book van Fraassen argues that no metaphysical account of laws can succeed. He analyzes and rejects the arguments that there are laws of nature, or that we must believe there are, and argues that we should disregard the idea of law as an inadequate clue to science. After exploring what this means for general epistemology, the author develops the empiricist view of science as a construction of models to represent the phenomena.

Laws and Symmetry

Metaphysicians speak of laws of nature in terms of necessity and universality, and that conception played a role in the birth of modern physics some centuries ago, but today physicists speak in terms of symmetry, transformations, and invariance. Laws and Symmetry's three main objectives are: first, to show the failure of current philosophical accounts of laws of nature; second, to refute arguments for the reality of laws of nature; third, to contrib ute to an epistemology and a philosophy of science antithetical to such metaphysical notions. The latter involves an inquiry into the character an The latter involves an inquiry into the character and role of symmetry and of symmetry arguments in the physical sciences. Keywords: epistemology , invariance , laws of nature , necessity , philosophy of physics , philosophy of science , symmetry. Bas C.
