ISBN Laws and Lawmakers ( Science Metaphysics and the Laws of Nature ) book English Hardcover 280 pages

Laws of nature have long puzzled philosophers. What distinguishes laws from facts about the world that do not rise to the level of laws? How can laws be contingent and nevertheless necessary? In this brief accessible study Lange offers provocative and original answers to these questions. He argues that laws are distinguished by their necessity which is grounded in primitive subjunctive facts (expressed by counterfactual conditionals). While recognizing that natural necessity is distinct from logical metaphysical and mathematical necessity Lange explains how natural necessity constitutes a species of the same genus as those other varieties of necessity. Along the way Lange discusses the relation between laws and objective chances as well as such unjustly neglected topics as the completeness of the laws of physics and whether the laws of nature can change. Lange's elegant engagingly written book is non-technical and suitable for undergraduate philosophers (and undergraduate scientists interested in the logical foundations of science). It is must reading for metaphysicians and philosophers of science working on laws chance counterfactuals modality or the philosophy of physics.
