Lawrence Sklar

The study of the physical world had its origins in philosophy, and, two-and-one-half millennia later, the scientific advances of the twentieth century are bringing the two fields closer together again. So argues Lawrence Sklar in this brilliant new text on the philosophy of physics.Aimed at students of both disciplines, Philosophy of Physics is a broad overview of the problems of contemporary philosophy of physics that readers of all levels of sophistication should find accessible and engaging. Professor Sklar's talent for clarity and accuracy is on display throughout as he guides students through the key problems: the nature of space and time, the problems of probability and irreversibility in statistical mechanics, and, of course, the many notorious problems raised by quantum mechanics.Integrated by the theme of the interconnectedness of philosophy and science, and linked by many references to the history of both disciplines, Philosophy of Physics is always clear, while remaining faithful to the complexity and integrity of the issues. It will take its place as a classic text in a field of fundamental intellectual importance.

Although now replaced by more modern theories, classical mechanics remains a core foundational element of physical theory. From its inception, the theory of dynamics has been riddled with conceptual issues and differing philosophical interpretations and throughout its long historical development, it has shown subtle conceptual refinement. The interpretive program for the theory has also shown deep evolutionary change over time. Lawrence Sklar discusses crucial issues in the central theory from which contemporary foundational theories are derived and shows how some core issues (the nature of force, the place of absolute reference frames) have nevertheless remained deep puzzles despite the increasingly sophisticated understanding of the theory which has been acquired over time. His book will be of great interest to philosophers of science, philosophers in general and physicists concerned with foundational interpretive issues in their field.

Skeptics have cast doubt on the idea that scientific theories give us a true picture of an objective world. Lawrence Sklar examines three kinds of skeptical arguments about scientific truth, and explores the important role that these play within foundational science itself, especially physics. First, doubts have been expressed about the legitimacy of claiming truth for assertions about the realm of the unobservable. Second, scientific theories have been characterized as relying heavily on idealization of the physical systems they seek to describe. Third, it is noted that scientific theories tend to be transient, and even the best currently available are expected to be replaced in the future. Sklar demonstrates that these kinds of philosophical critique are employed within science itself, and reveals the clear difference between how they operate in a scientific and in a more abstract philosophical context. The underlying theme of Theory and Truth is that science and philosophy are essential to, and inextricable from, each other. One cannot understand the methods of science except by understanding philosophy, and one cannot fruitfully pursue philosophy of science without understanding foundational science as well.

Statistical mechanics is one of the crucial fundamental theories of physics, and in his new book Lawrence Sklar, one of the pre-eminent philosophers of physics, offers a comprehensive, non-technical introduction to that theory and to attempts to understand its foundational elements. Among the topics treated in detail are probability and statistical explanation, the basic issues in both equilibrium and non-equilibrium statistical mechanics, the role of cosmology, the reduction of thermodynamics to statistical mechanics, and the alleged foundation of the very notion of time asymmetry in the entropic asymmetry of systems in time. The book emphasises the interaction of scientific and philosophical modes of reasoning, and in this way will interest all philosophers of science as well as those in physics and chemistry concerned with philosophical questions. The book could also be read by an informed general reader interested in the foundations of modern science.

The systematic study of the physical world had its orgins in philosophy; two-and-a-half millennia later, the scientific advances of the twentieth century are bringing the two fields closer together again. In this brilliant new textbook, Lawrence Sklar gives a broad overview of contemporary philosophy of physics which readers at all levels, especially students, should find accessible and engaging. Professor Sklar provides a clear and accurate guide to the key topics: the nature of space and time, the problems of probability and irreversibility in statistical mechanics, and, of course, the many notorious problems raised by quantum mechanics. He discusses sophisticated scientific questions, but avoids the use of technical formalism, so that the discussion will be accessible to those without a training in philosophy or physics.

In this book, Lawrence Sklar demonstrates the interdependence of science and philosophy by examining a number of crucial problems on the nature of space and time - problems that require for their resolution the resources of philosophy and of physics. The overall issues explored are our knowledge of the geometry of the world, the existence of spacetime as an entity over and above the material objects of the world, the relation between temporal order and causal order, and the problem of the direction of time. Without neglecting the most subtle philosophical points or the most advanced contributions of contemporary physics, the author has taken pains to make his explorations intelligible to the reader with no advanced training in physics, mathematics, or philosophy. The arguments are set forth step-by-step, beginning from first principles; and, the philosophical discussions are supplemented in detail by nontechnical expositions of crucial features of physical theories.
