“Knowledge can be acquired by a suitable and complete study, no matter what the starting point is. Only one must know how to 'learn.' What is nearest to us is man; and you are the nearest of all men to yourself. Begin with the study of yourself; remember the saying 'Know thyself.”

“To acquire knowledge, one must study;but to acquire wisdom, one must observe.”

“It does not matter where you go and what you study, what matters most is what you share with yourself and the world.”

“Knowing yourself means knowing, first, what it is to be a person; secondly, knowing what it is to be the kind of person you are; and thirdly, knowing what it is to be the person you are and nobody else is. Knowing yourself means knowing what you can do; and since nobody knows what they can do until they try, The only clue to what man can do is what man has done. The value of history, then, is that it teaches us what man has done and thus what man is.”

“Know thyself, presume not God to scan;The proper study of mankind is man.”
