It is the greatest mistake to think that man is always one and the same. A man is never the same for long. He is continually changing. He seldom remains the same even for half an hour.
Consciousness is a state in which a man knows all at once everything that he in general knows and in which he can see how little he does know and how many contradictions there are in what he knows.
Without self knowledge, without understanding the working and functions of his machine, man cannot be free, he cannot govern himself and he will always remain a slave.
