74. Preliminary Studies for On the Human Riddle

When Mach speaks of sensation, he is pointing to that which is felt; but in thinking the object of the sensation, he must separate it from the ego. He does not realize that by doing so, he is thinking something that can no longer be felt. He also shows this by the fact that the concept of the ego completely dissipates. That he actually loses the “I” completely. It becomes a mythical concept. Because he does not consciously think of his world of feeling as imperceptible, it throws the perceiving ego out of his thinking. Thus Mach's view in particular becomes proof of what has been explained here.
