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

Morality arose largely as an empirical defence of the individual and society. Ever since intelligent beings began to be in contact, and consequently in friction, they have felt the need to guard themselves against each other’s encroachments.

I reject any religious doctrine that does not appeal to reason and is in conflict with morality.

There is a real danger that computers will develop intelligence and take over. We urgently need to develop direct connections to the brain so that computers can add to human intelligence rather than be in opposition.

If it is not right do not do it; if it is not true do not say it.

If you’re not going to be rewarded for your virtues, and instead you’re going to be punished for them, then what’s your motivation to continue?

There is a moral obligation that those who have should give to those who don’t.

I think where political issues invade moral situations, spiritual leaders have to speak out.

With music, you often don’t have to translate it. It just affects you, and you don’t know why.

To assert in any case that a man must be absolutely cut off from society because he is absolutely evil amounts to saying that society is absolutely good, and no-one in his right mind will believe this today.

Of two evils, choose neither.

Justice is the set and constant purpose which gives every man his due.

All sciences are now under the obligation to prepare the ground for the future task of the philosopher, which is to solve the problem of value, to determine the true hierarchy of values.

Ethics is the activity of man directed to secure the inner perfection of his own personality.

To cut short the question of the law of retaliation, we must note that even in its primitive form it can operate only between two individuals of whom one is absolutely innocent, and the other absolutely guilty. The victim, to be sure, is innocent. But can the society that is supposed to represent the victim lay claim to innocence?

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

Well, I’ll put it this way: you can certainly say belief in God makes people behave worse. That can be proved beyond a doubt.

We all have the duty to do good.

The world is all the richer for having a devil in it, so long as we keep our foot upon his neck.

Saints should always be judged guilty until they are proved innocent.

Morality is the herd-instinct in the individual.

One of the great attractions of patriotism – it fulfills our worst wishes. In the person of our nation we are able, vicariously, to bully and cheat. Bully and cheat, what’s more, with a feeling that we are profoundly virtuous.

We are much beholden to Machiavel and others, that write what men do, and not what they ought to do.

Politics have no relation to morals.

Principles are guidelines for human conduct that are proven to have enduring, permanent value.

Every art and every inquiry, and similarly every action and choice, is thought to aim at some good; and for this reason the good has rightly been declared to be that at which all things aim.

Those who forget good and evil and seek only to know the facts are more likely to achieve good than those who view the world through the distorting medium of their own desires.

Mankind is not likely to salvage civilization unless he can evolve a system of good and evil which is independent of heaven and hell.

Every man must decide whether he will walk in the light of creative altruism or in the darkness of destructive selfishness.

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.

Honor has not to be won; it must only not be lost.

I’m such an emotional and sensitive person, so it only makes sense that my songs are as well.

Immorality: the morality of those who are having a better time.

Hatred is gained as much by good works as by evil.

All of us knows, not what is expedient, not what is going to make us popular, not what the policy is, or the company policy – but in truth each of us knows what is the right thing to do. And that’s how I am guided.

In Christianity neither morality nor religion come into contact with reality at any point.

How shall I lose the sin, yet keep the sense, and love the offender, yet detest the offence?

Those who don’t know how to weep with their whole heart, don’t know how to laugh either.

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

It is right to give every man his due.

It is now quite lawful for a Catholic woman to avoid pregnancy by a resort to mathematics, though she is still forbidden to resort to physics or chemistry.

I am afraid we must make the world honest before we can honestly say to our children that honesty is the best policy.

What can I know? What ought I to do? What can I hope?

Chastity does not mean abstention from sexual wrong; it means something flaming, like Joan of Arc.

So far as I am concerned, I could not be accused of having set eyes, or having wished to set eyes, upon Darius‘ wife: on the contrary, I have refused even to listen to those who spoke to me of her beauty.

Morality which depends upon the helplessness of a man or woman has not much to recommend it. Morality is rooted in the purity of our hearts.

The knighthood was a tremendous honour, I don’t dismiss it. But I feel embarrassed by the flowery, theatrical stuff that goes with being an actor.

Any religion that professes to be concerned about the souls of men and is not concerned about the slums that damn them, the economic conditions that strangle them and the social conditions that cripple them is a spiritually moribund religion awaiting burial.

Blessedness is not the reward of virtue but virtue itself.

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?

Never pretend to a love which you do not actually feel, for love is not ours to command.

I’ll never tell a lie. I’ll never make a misleading statement. I’ll never betray the confidence that any of you had in me. And I’ll never avoid a controversial issue.

I do think there should be some regulations on AI.

I know of only one duty, and that is to love.

I’ve often felt depressed; everyone feels depressed.

Evil is the product of the ability of humans to make abstract that which is concrete.

A man is truly ethical only when he obeys the compulsion to help all life which he is able to assist, and shrinks from injuring anything that lives.

Honor is simply the morality of superior men.

It is better to risk saving a guilty man than to condemn an innocent one.
