The impression we get after going through these almost six hundred pages of Schopenhauer’s biography signed by David Cartwright is just one: Schopenhauer is an authentic philosopher. This can be seen because, for anyone familiar with Schopenhauer’s work, his biography holds no surprises, which is tantamount to saying that his life was consistent with his philosophy or, rather, that his philosophy was real. To measure the difficulty, and perhaps the greatness of this feat, it is enough to compare it to the abundant miseries described by Paul Johnson in the lives of his intellectuals. In Schopenhauer, we see a personality engraved in every act, in every reaction; we see a man who, despite what can be said about him, neither betrayed nor falsified himself. Such integrity, which is extremely rare, deserves the highest recognition.
