Non-cooperation with evil is as much a duty as is cooperation with good.

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

Virtue is not left to stand alone. He who practices it will have neighbors.

Abortion is clearly wrong.

Ought we not to ask the media to agree among themselves a voluntary code of conduct, under which they would not say or show anything which could assist the terrorists‘ morale or their cause while the hijack lasted.

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.

Of all the varieties of virtues, liberalism is the most beloved.

That old law about ‚an eye for an eye‘ leaves everybody blind. The time is always right to do the right thing.

Sadly, of course, there is real evil in the world. You watch the news, and you see all of the people suffering and so much cruelty.

What is permissible is not always honorable.

I love to go to the zoo. But not on Sunday. I don’t like to see the people making fun of the animals, when it should be the other way around.

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

All philosophy lies in two words, sustain and abstain.

What is moral is what you feel good after, and what is immoral is what you feel bad after.

Violence is both unavoidable and unjustifiable.

Every man has the right to risk his own life in order to preserve it. Has it ever been said that a man who throws himself out the window to escape from a fire is guilty of suicide?

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.

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.‘

You cannot be in a position of power and destroy the life of another person.

Can anything be stupider than that a man has the right to kill me because he lives on the other side of a river and his ruler has a quarrel with mine, though I have not quarrelled with him?

To terrify children with the image of hell… to consider women an inferior creation. Is that good for the world?

You may be educated abroad, you may be a great scientist, politician, but you always have a sneaking fear that if you don’t go to temples or do the ordinary things that you have been told to do, something evil might happen, so you conform. What happens to the mind that conforms? Investigate it, please.

I hope I shall possess firmness and virtue enough to maintain what I consider the most enviable of all titles, the character of an honest man.

Live one day at a time emphasizing ethics rather than rules.

Blessedness is not the reward of virtue but virtue itself.

If you’re in favour of any policy – reform, revolution, stability, regression, whatever – if you’re at least minimally moral, it’s because you think it’s somehow good for people. And good for people means conforming to their fundamental nature.

We’re all caught up in circumstances, and we’re all good and evil. When you’re really hungry, for instance, you’ll do anything to survive. I think the most evil thing – well, maybe that’s too strong – but certainly a very evil thing is judgment, the sin of ignorance.

There is no kind of dishonesty into which otherwise good people more easily and frequently fall than that of defrauding the government.

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.

No obligation to do the impossible is binding.

I object to violence because when it appears to do good, the good is only temporary; the evil it does is permanent.

The greatest destroyer of peace is abortion because if a mother can kill her own child, what is left for me to kill you and you to kill me? There is nothing between.

States are not moral agents.

Success consecrates the most offensive crimes.

Understand, when you eat meat, that something did die. You have an obligation to value it – not just the sirloin but also all those wonderful tough little bits.

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.

A moral monopoly is the antithesis of a marketplace of ideas.

What the statesman is most anxious to produce is a certain moral character in his fellow citizens, namely a disposition to virtue and the performance of virtuous actions.

It is best to avoid the beginnings of evil.

The moral virtues, then, are produced in us neither by nature nor against nature. Nature, indeed, prepares in us the ground for their reception, but their complete formation is the product of habit.

The humanists‘ replacement for religion: work really hard and somehow you’ll either save yourself or you’ll be immortal. Of course, that’s a total joke, and our progress is nothing. There may be progress in technology but there’s no ethical progress whatsoever.

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.

A strong argument for the religion of Christ is this – that offences against Charity are about the only ones which men on their death-beds can be made – not to understand – but to feel – as crime.

Science may have found a cure for most evils; but it has found no remedy for the worst of them all – the apathy of human beings.

Love is the joy of the good, the wonder of the wise, the amazement of the Gods.

Under a government which imprisons any unjustly, the true place for a just man is also a prison.

Politics have no relation to morals.

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

I just know what is right and I want to do what is right.

Good jokes are gems. A good idea is hard to come by. I couldn’t give them to someone else, even for money. It just wouldn’t seem right.

Let me give you a definition of ethics: It is good to maintain and further life it is bad to damage and destroy life.

Ignorance, the root and stem of all evil.

If we do not maintain justice, justice will not maintain us.

As individuals, people are inherently good. I have a somewhat more pessimistic view of people in groups. And I remain extremely concerned when I see what’s happening in our country, which is in many ways the luckiest place in the world. We don’t seem to be excited about making our country a better place for our kids.

I do not recognize the right of the public to break in the front door of a man’s private life in order to satisfy the gaze of the curious… I do not think it right to dissect living men even for the advancement of science. So far as I am concerned, I prefer a post mortem examination to vivisection without anaesthetics.

When you look at a corporation, just like when you look at a slave owner, you want to distinguish between the institution and the individual. So slavery, for example, or other forms of tyranny, are inherently monstrous. The individuals participating in them may be the nicest guys you can imagine.

It is forbidden to kill; therefore all murderers are punished unless they kill in large numbers and to the sound of trumpets.

God is dead. God remains dead. And we have killed him. Yet his shadow still looms. How shall we comfort ourselves, the murderers of all murderers? What was holiest and mightiest of all that the world has yet owned has bled to death under our knives; who will wipe this blood off us? What water is there for us to clean ourselves?

Compassion is the basis of morality.

Conscience is a man’s compass.

There’s strong data that, within companies, the No. 1 reason for ethical violations is the pressure to meet expectations, sometimes unrealistic expectations.
