Every intelligent individual wants to know what makes him tick, and yet is at once fascinated and frustrated by the fact that oneself is the most difficult of all things to know.
The myths underlying our culture and underlying our common sense have not taught us to feel identical with the universe, but only parts of it, only in it, only confronting it - aliens... within I don't know how many years, but in not too long a time, it's going to become basic common sense that you are not some alien being who confronts an external world that is not you, but that almost every intelligent person will have the feeling of being an activity of the entire universe.
We know that the Zanj (blacks) are the least intelligent and the least discerning of mankind, and the least capable of understanding the consequences of actions.
Now I'm living out my life in a corner, trying to console myself with the stupid, useless excuse that an intelligent man cannot turn himself into anything, that only a fool can make anything he wants out of himself.
At present, intelligent people do not have their children vaccinated, nor does the law now compel them to. The result is not, as the Jennerians prophesied, the extermination of the human race by smallpox; on the contrary more people are now killed by vaccination than by smallpox.

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.
Even the greatest fool can accomplish a task if it be after his heart. But the intelligent man is he who can convert every work into one that suits his taste. No work is petty. Everything in this world is like a banyan seed, which, though appearing tiny as a mustard seed, has yet the gigantic banyan tree latent with it. He indeed is intelligent who notices this and succeeds in making all work truly great.
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.
The intelligent person is not one who merely knows what is good and what is bad. The intelligent person is one who, when he sees what is good, follows it, and when he sees evil, shuns it.
