Science is but an image of the truth.

Reverence for life affords me my fundamental principle of morality.

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

I do not know how to teach philosophy without becoming a disturber of established religion.

Death is not the worst that can happen to men.

Morality is the basis of things and truth is the substance of all morality.

It was one of those evenings when men feel that truth, goodness and beauty are one. In the morning, when they commit their discovery to paper, when others read it written there, it looks wholly ridiculous.

No one wants to die. Even people who want to go to heaven don’t want to die to get there. And yet death is the destination we all share. No one has ever escaped it. And that is as it should be, because Death is very likely the single best invention of Life. It is Life’s change agent. It clears out the old to make way for the new.

You don’t have to be scared of me, because I am loyal. Why are people so scared of creative ideas and so scared of truth? All I want to do is do good.

After your death you will be what you were before your birth.

It was a favorite expression of Theophrastus that time was the most valuable thing that a man could spend.

Leave it as it is. The ages have been at work on it and man can only mar it.

I did used to have nightmares about the idea that when I die, there is a spark of consciousness which basically creates the world. ‚Is the world going to disappear if this spark of consciousness disappears? And how do I know it won’t? How do I know there’s anything there except what I’m conscious of?‘

Nothing is at last sacred but the integrity of your own mind.

Therefore, the good of man must be the end of the science of politics.

What is imponderable in the world is greater than what we can handle.

I’m never going to go to Mars, but I’ve helped inspire, thank goodness, the people who built the rockets and sent our photographic equipment off to Mars.

Every man is more than just himself; he also represents the unique, the very special and always significant and remarkable point at which the world’s phenomena intersect, only once in this way, and never again.

Wisdom oft times consists of knowing what to do next.

Then not only custom, but also nature affirms that to do is more disgraceful than to suffer injustice, and that justice is equality.

It is the eye of other people that ruin us. If I were blind I would want, neither fine clothes, fine houses or fine furniture.

A radical generally meant a man who thought he could somehow pull up the root without affecting the flower. A conservative generally meant a man who wanted to conserve everything except his own reason for conserving anything.

Pessimism is a luxury that a Jew can never allow himself.

So act that your principle of action might safely be made a law for the whole world.

No one can outrun death. It will catch up to all of us eventually.

To live outside the law, you must be honest.

Proselytism is solemn nonsense; it makes no sense. We need to get to know each other, listen to each other and improve our knowledge of the world around us.

Truth is mighty and will prevail. There is nothing wrong with this, except that it ain’t so.

Europe was created by history. America was created by philosophy.

A little learning is a dangerous thing, but we must take that risk because a little is as much as our biggest heads can hold.

I am the wisest man alive, for I know one thing, and that is that I know nothing.

Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce.

I don’t know what’s the matter with people: they don’t learn by understanding; they learn by some other way – by rote, or something. Their knowledge is so fragile!

As long as your body is healthy and under control and death is distant, try to save your soul; when death is immanent what can you do?

Sometimes one pays most for the things one gets for nothing.

I have been so great in boxing they had to create an image like Rocky, a white image on the screen, to counteract my image in the ring. America has to have its white images, no matter where it gets them. Jesus, Wonder Woman, Tarzan and Rocky.

Indignation is a submission of our thoughts, but not of our desires.

It has been said that man is a rational animal. All my life I have been searching for evidence which could support this.

I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.

Life consists in what a man is thinking of all day.

‚Happiness‘ is a pointless goal.

The world is a republic of mediocrities, and always was.

At the center of non-violence stands the principle of love.

I have lived eighty years of life and know nothing for it, but to be resigned and tell myself that flies are born to be eaten by spiders and man to be devoured by sorrow.

Do not impose on others what you yourself do not desire.

When I was very young I was sort of floored by the fact that my mother and my father and everyone I knew was going to die one day, and myself too. I had a sort of a philosophical crisis. I couldn’t believe that we were mortal.

No man was ever wise by chance.

Whatever the universal nature assigns to any man at any time is for the good of that man at that time.

Only on the edge of the grave can man conclude anything.

Simplicity is the most deceitful mistress that ever betrayed man.

All that we see or seem is but a dream within a dream.

Chaos is inherent in all compounded things. Strive on with diligence.

The credit of advancing science has always been due to individuals and never to the age.

‚I wish life was not so short,‘ he thought. ‚Languages take such a time, and so do all the things one wants to know about.‘

We do not need to proselytise either by our speech or by our writing. We can only do so really with our lives. Let our lives be open books for all to study.

It is more fitting for a man to laugh at life than to lament over it.

I had rather believe all the Fables in the Legend, and the Talmud, and the Alcoran, than that this universal frame is without a Mind.

The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

All things in the world come from being. And being comes from non-being.

Say not, ‚I have found the truth,‘ but rather, ‚I have found a truth.‘

It is incomprehensible that God should exist, and it is incomprehensible that he should not exist.
