Context: One of man’s important mistakes, one which must be remembered, is his illusion in regard to his I.
Man such as we know him, the "man-machine," the man who cannot "do," and with whom and through whom everything "happens," cannot have a permanent and single I. His I changes as quickly as his thoughts, feelings and moods, and he makes a profound mistake in considering himself always one and the same person; in reality he is always a different person, not the one he was a moment ago.
