people, nietzsche maintains, mistakenly believe that they make decisions freely, attributing these decisions to the “inner facts” or notions of will, spirit, and ego. nietzsche argues against the existence of these three notions. for example, will does not cause events to occur, it only accompanied them (nietzsche also points out that it is possible for some events to not be accompanied by any will). similarly, nietzsche holds that spirit, in the form of motive, is merely an accompaniment to an action, but not a cause of it. finally, he argues that the ego is simply a fiction. in short, there are no spiritual causes for human behavior.
