A brilliant presentation, concise and concentrated, of the thought of Karl Popper with its main complementary components: science, philosophy, epistemology and politics; all in application of his evolutionary rationalism, his theory of Knowledge.
Bryan Magee shows very well the unity of methodology in Popper's works, upon what the author called critical rationalism in philosophy and epistemology, and "piecemeal social engineering" in politics. The great philosopher of sciences disapproved essentialism, determinism, and historicism, throughout all the matters the more important is the use of the good method, with a good conception of reason and science, so a logic of scientific discovery. It is a matter of scientific progress, of knowledge and culture in general, and of democracy (differing from utopias). Finally the reader is advised to turn to Popper's books.
