"Schopenhauer's analyses of causation and related concepts . . . rival and probably surpass in their depth and brilliance the more celebrated discussions of David Hume. Where Hume grossly oversimplified these problems and left them riddled with paradoxes, Schopenhauer disentangled them and shed light on what had seemed hopelessly dark." --Richard Taylor, University of Rochester

This book is a philosophical commentary on Schopenhauer's "Fourfold Root of the Principle of Sufficient Reason," dealing with each of Schopenhauer's principal topics in turn. It also provides the reader with a general survey of Schopenhauer's later philosophical views and puts them into an historical context

Originally published in 1813, this early work by German philosopher Arthur Schopenhauer is both expensive and hard to find in its first edition. Originally published as his doctoral dissertation and then later re-published, it outlines his cornerstone arguments on the subject of knowing. This fascinating work is highly recommended for anyone interested in 19th century philosophy and its development. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

This volume of translations unites three shorter works by Arthur Schopenhauer that expand on themes from his book The World as Will and Representation. In On the Fourfold Root he takes the principle of sufficient reason, which states that nothing is without a reason why it is, and shows how it covers different forms of explanation or ground that previous philosophers have tended to confuse. Schopenhauer regarded this study, which he first wrote as his doctoral dissertation, as an essential preliminary to The World as Will. On Will in Nature examines contemporary scientific findings in search of corroboration of his thesis that processes in nature are all a species of striving towards ends; and On Vision and Colours defends an anti-Newtonian account of colour perception influenced by Goethe's famous colour theory. This is the first English edition to provide extensive editorial notes on the different published versions of these works.
