Lecture VI

A person may at first try a path by means of his life of thought, i.e., attempt to depict the I to himself. Especially people who are philosophically inclined have in recent years become convinced that this is a secure path. They will say: That which I look upon as I remains from birth to death the same entity. If I look back in memory over my life, I find that I am always the same. However, this statement is contradicted daily for every normal human being, as I have often pointed out. Between going to sleep and waking the ordinary person has no means of knowing how things concerning the I really are. He has no external observation of the I during sleep. The I he depicts to himself he can only relate to the times he was awake; during sleep the chain of his life's external events is broken. This is easy enough to see. Therefore, he who believes that the I lives in his thoughts, in such a way that he can actually find it there, must recognize that it is blotted out every time he sleeps, at least as far as his consciousness is concerned. Something which plunges into darkness and becomes imperceptible every night cannot be regarded as having a secure existence.
