A man cannot utter two or three sentences without disclosing to intelligent ears precisely where he stands in life and thought, whether in the kingdom of the senses and the understanding, or in that of ideas and imagination, or in the realm of intuitions and duty.
The most intelligent men, like the strongest, find their happiness where others would find only disaster: in the labyrinth, in being hard with themselves and with others, in effort; their delight is self-mastery; in them asceticism becomes second nature, a necessity, as instinct.
We are intelligent beings: intelligent beings cannot have been formed by a crude, blind, insensible being: there is certainly some difference between the ideas of Newton and the dung of a mule. Newton's intelligence, therefore, came from another intelligence
It has always been my opinion since I first possessed such a thing as an opinion, that the man who knows only one subject is next tiresome to the man who knows no subject. Therefore, in the course of my life I have taught myself whatever I could, and although I am not an educated man, I am able, I am thankful to say, to have an intelligent interest in most things.
I could not become anything; neither good nor bad; neither a scoundrel nor an honest man; neither a hero nor an insect. And now I am eking out my days in my corner, taunting myself with the bitter and entirely useless consolation that an intelligent man cannot seriously become anything, that only a fool can become something.
I came to realize that I was always looking for myself in the women I loved. I looked at their lovely, clean faces, and saw myself reflected in them. They, on the other hand, looked at me and saw the dirt on my face and, however intelligent and self confident they were, they ended up seeing themselves reflected in me and thinking that they were worse than they were. Please don't let that happen to you.
Life is very narrow. Bring any club or company of intelligent men together again after ten years, and if the presence of some penetrating and calming genius could dispose them to frankness, what a confession of insanities would come up!
Inability to accept the mystic experience is more than an intellectual handicap. Lack of awareness of the basic unity of organism and environment is a serious and dangerous hallucination. For in a civilization equipped with immense technological power, the sense of alienation between man and nature leads to the use of technology in a hostile spirit—-to the “conquest” of nature instead of intelligent co-operation with nature.
