Schopenhauer dealt intensively with Spinoza throughout his whole life. This includes not only enthusiastic agreement, but also harsh rejection. Spinozas peculiar use of words caused some misunderstandings, which are clarified here. In the course of this, it turns out that Schopenhauers fundamental view is the same as Spinozas, which he does not even acknowledge. According to Schopenhauer, Spinoza fails to solve the problem of all ethics, and he provides a fix by borrowing some of Spinozas own ideas and giving his metaphysics a twist.
