By carefully examining one of the most famous thought experiments in the history of science—that by which Galileo is said to have refuted the Aristotelian theory that heavier bodies fall faster than lighter ones—I attempt to show that thought experiments play a distinctive role in scientific inquiry. Reasoning about particular entities within the context of an imaginary scenario can lead to rationally justified concluusions that—given the same initial information—would not be rationally justifiable on the basis of a straightforward argument.

This best-selling dictionary is written by one of the most famous philosophers of our time, and it is widely recognized as the best dictionary of its kind. Comprehensive and authoritative, it covers every aspect of philosophy from Aristotle to Zen. With clear and concise definitions, it provides lively and accessible coverage of not only Western philosophical traditions, but also themes from Chinese, Indian, Islamic, and Jewish philosophy. Entries include over 500 biographies of famous and influential philosophers, in-depth analysis of philosophical (...) terms and concepts, and a chronology of philosophical events stretching from 10,000 BC to the present day. The first edition of this dictionary became a market-leader and a standard work of reference, selling over 100,000 copies. Now the author, Professor Simon Blackburn, has revised it to include web links which provide up-to-date and valuable extra information via the Dictionary of Philosophy companion website. Fully cross-referenced and containing over 3,000 alphabetical entries, it is the ideal introduction to philosophy for anyone with an interest in the subject, and it is an indispensable work of reference for students and teachers.
