Egoism is the very essence of a noble soul.

God gives the nuts, but he does not crack them.

If it’s true that our species is alone in the universe, then I’d have to say the universe aimed rather low and settled for very little.

It is a bit embarrassing to have been concerned with the human problem all one’s life and find at the end that one has no more to offer by way of advice than ‚try to be a little kinder.‘

When we remember we are all mad, the mysteries disappear and life stands explained.

A jug fills drop by drop.

All nature is but art unknown to thee.

I am against nature. I don’t dig nature at all. I think nature is very unnatural. I think the truly natural things are dreams, which nature can’t touch with decay.

One of the first signs of the beginning of understanding is the wish to die.

Words are only painted fire; a look is the fire itself.

Abortion isn’t a lesser evil, it’s a crime. Taking one life to save another, that’s what the Mafia does. It’s a crime. It’s an absolute evil.

If you think only of evil, then you become pessimistic and hopeless like Freud. But if you think there is no evil, then you’re just one more deluded Pollyanna.

If there is something to pardon in everything, there is also something to condemn.

Rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. I do not add ‚within the limits of the law‘ because law is often but the tyrant’s will, and always so when it violates the rights of the individual.

A new philosophy generally means in practice the praise of some old vice.

What can everyone do? Praise and blame. This is human virtue, this is human madness.

What difference does it make to the dead, the orphans, and the homeless, whether the mad destruction is wrought under the name of totalitarianism or the holy name of liberty or democracy?

The art of living well and the art of dying well are one.

Science is global. Einstein’s equation, E=mc2, has to reach everywhere. Science is a beautiful gift to humanity, we should not distort it. Science does not differentiate between multiple races.

Time stays, we go.

We must accept what science tells us, that man was born from the earth. But, more logical than the scientists who lecture us, we must carry this lesson to its conclusion: that is to say, accept that man was born entirely from the world – not only his flesh and bones but his incredible power of thought.

Philosophically considered, the universe is composed of Nature and the Soul. Strictly speaking, therefore, all that is separate from us, all which Philosophy distinguishes as the ‚Not Me,‘ that is, both nature and art, all other men and my own body, must be ranked under this name, ‚Nature.‘

A weak man is just by accident. A strong but non-violent man is unjust by accident.

Infinites, when considered absolutely without any restriction or limitation, are neither equal nor unequal, nor have any certain proportion one to another, and therefore, the principle that all infinites are equal is a precarious one.
