While philosophy of science has always been an integral part of philosophy, since the beginning of the twentieth century it has developed its own structure and its fair share of technical vocabulary and problems. Philosophy of Science A-Z gives concise, accurate and illuminating accounts of key positions, concepts, arguments and figures in the philosophy of science from A priori/a posteriori to Elie Zahar. It aids understanding of current debates, explains their historical development and connects them with broader philosophical issues. It presupposes little prior knowledge of philosophy of science and is equally useful to the beginner, the more advanced student and the general reader. Readers will find in it illuminating explanations, careful analysis, relevant examples, open problems and, last but not least, precise arguments. Philosophy of science is a flourishing discipline and Philosophy of Science A to Z is a practical and imaginative way into and through it.
