To fear death, my friends, is only to think ourselves wise without really being wise, for it is to think that we know what we do not know.

In order for man to succeed in life, God provided him with two means, education and physical activity. Not separately, one for the soul and the other for the body, but for the two together. With these means, man can attain perfection.

No human thing is of serious importance.

Justice is nothing more than the advantage of the stronger.

Science is nothing but perception.

If you ask: What is the good of education? The answer is easy: Education makes good men and good men act nobly.

The principles are important. First, the interest of the state or society counts for everything, that of the individual for nothing. Second, the only difference between men and women is one of physical function- one begets, the other bears children. Apart from that, they both can and should perform the same functions - though men on a whole, perform them better and should receive the same education to enable them to do so; for in this way society will get the best value from both.
