All studies undertaken by human beings are always studies of themselves. The proper study of mankind is self. The heavens, earth, the mountains and the rivers, sun and moon and stars—they are all no more than other names for the self. There is nothing a man can study which is not, in the end, the study of the self. If a man could jump out of his self that self would disappear at the moment of his jumping. Nor is that all. Only oneself can study one’s self. It is totally impossible for anyone else to do it.
