Schopenhauer is the most readable of German philosophers. This book gives a succinct explanation of his metaphysical system, concentrating on the original aspects of his thought, which inspired many artists and thinkers including Nietzsche, Wagner, Freud, and Wittgenstein. Schopenhauer´s central notion is that of the will - a blind, irrational force that he uses to interpret both the human mind and the whole of nature. Seeing human behaviour as that of a natural organism governed by the will to life, Schopenhauer developed radical insights concerning the unconscious and sexuality which influenced both psychologists and philosophers.
