To God everything is beautiful, good, and just; humans, however, think some things are unjust and others just.

A good politician is quite as unthinkable as an honest burglar.

Whatever universe a professor believes in must at any rate be a universe that lends itself to lengthy discourse. A universe definable in two sentences is something for which the professorial intellect has no use. No faith in anything of that cheap kind!

Man is made to adore and to obey: but if you will not command him, if you give him nothing to worship, he will fashion his own divinities, and find a chieftain in his own passions.

Let us be moral. Let us contemplate existence.

The philosophical idea that there are no more distances, that we are all just one world, that we are all brothers, is such a drag! I like differences.

It’s that wonderful old-fashioned idea that others come first and you come second. This was the whole ethic by which I was brought up. Others matter more than you do, so ‚don’t fuss, dear; get on with it.‘

Absence of evidence is not evidence of absence.

Light troubles speak; the weighty are struck dumb.

Everything has been figured out, except how to live.

One of the most tragic things I know about human nature is that all of us tend to put off living. We are all dreaming of some magical rose garden over the horizon instead of enjoying the roses that are blooming outside our windows today.

The cause of my life has been to oppose superstition. It’s a battle you can’t hope to win – it’s a battle that’s going to go on forever. It’s part of the human condition.

Only the ideas that we really live have any value.

Despise not death, but welcome it, for nature wills it like all else.

Truth is ever to be found in simplicity, and not in the multiplicity and confusion of things.

The pursuit of truth does not permit violence on one’s opponent.

Thinking is more interesting than knowing, but less interesting than looking.

I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use.

The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?

Regarding life, the wisest men of all ages have judged alike: it is worthless.

Which death is preferably to every other? ‚The unexpected‘.

Although modesty is natural to man, it is not natural to children. Modesty only begins with the knowledge of evil.

A man’s as miserable as he thinks he is.

The cost of a thing is the amount of what I will call life which is required to be exchanged for it, immediately or in the long run.

I do think there should be some regulations on AI.

Science is increasingly answering questions that used to be the province of religion.

We’re all of us guinea pigs in the laboratory of God. Humanity is just a work in progress.

There is always something infinitely mean about other people’s tragedies.

Who is the wisest man? He who neither knows or wishes for anything else than what happens.

If you would convince a man that he does wrong, do right. Men will believe what they see.

Truth is beautiful, without doubt; but so are lies.

I think God gives every one of us our own will, and unfortunately, some people choose to do evil things with it.

Success in creating AI would be the biggest event in human history. Unfortunately, it might also be the last, unless we learn how to avoid the risks.

You are a child of the sun, you come from the sun, and that is something true with the Earth also… your relationship with the Earth is so deep, and the Earth is in you and this is something not very difficult, much less difficult then philosophy.

It is more from carelessness about truth than from intentionally lying that there is so much falsehood in the world.

One may no more live in the world without picking up the moral prejudices of the world than one will be able to go to hell without perspiring.

The universe is change; our life is what our thoughts make it.

The world is like a grand staircase, some are going up and some are going down.

In the game of cricket, a hero is a person who respects the game and does not corrupt the game. The one who doesn’t or corrupts the game, they are the villain. They should be punished, and they have been punished in the past.

We conceal it from ourselves in vain – we must always love something. In those matters seemingly removed from love, the feeling is secretly to be found, and man cannot possibly live for a moment without it.

I say, beware of all enterprises that require new clothes, and not rather a new wearer of clothes.

We need to have business leaders who live by deep, strong principles.

For as the eyes of bats are to the blaze of day, so is the reason in our soul to the things which are by nature most evident of all.

Man is but a reed, the most feeble thing in nature, but he is a thinking reed.

I don’t suffer of anything that I’ve lost.

Even philosophers will praise war as ennobling mankind, forgetting the Greek who said: ‚War is bad in that it begets more evil than it kills.‘

The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane.

Never let your sense of morals get in the way of doing what’s right.

Religion is not a department of life; it is something that enters into the whole of it.

We grow older, but we do not change. We become more sophisticated, but at bottom we continue to resemble our young selves, eager to listen to the next story and the next, and the next.

It is sadder to find the past again and find it inadequate to the present than it is to have it elude you and remain forever a harmonious conception of memory.

Great ambition is the passion of a great character. Those endowed with it may perform very good or very bad acts. All depends on the principles which direct them.

Every man is rich or poor according to the proportion between his desires and his enjoyments.

To compromise simply means that you go a tiny bit below what you know is right.

Perhaps I know best why it is man alone who laughs; he alone suffers so deeply that he had to invent laughter.

About morals, I know only that what is moral is what you feel good after and what is immoral is what you feel bad after.

Yesterday’s weirdness is tomorrow’s reason why.

I have wondered about time all my life.

We are all ready to be savage in some cause. The difference between a good man and a bad one is the choice of the cause.
