Schopenhauer is one of the few philosophers who can be generally understood without a commentary. All his theories claim to be drawn direct from the facts, to be suggested by observation, and to interpret the world as it is; and whatever view he takes, he is constant in his appeal to the experience of common life. This characteristic endows his style with a freshness and vigor which would be difficult to match in the philosophical writing of any country, and impossible in that of Germany.
