The principle that the end justifies the means is and remains the only rule of political ethics; anything else is just a vague chatter and melts away between one’s fingers.

With nature on your side, you don’t need numbers, you don’t need financing and you certainly don’t need to make friends with people you should be fightingagainst.

Speech is not a means in the service of an external end. It contains its own rule of usage, ethics, and view of the world, as a gesture sometimes bears the whole truth about a man.

We have a choice. We have two options as human beings. We have a choice between conversation and war. That's it. Conversation and violence. And faith is a conversation stopper.

A true leader does not derive power from his position, but from his ethics, from people’s love for him, and from his knowledge, education and excellence in his field of work.

We make men without chests and expect of them virtue and enterprise. We laugh at honour and are shocked to find traitors in our midst. We castrate and bid the geldings be fruitful.

Evil ethicists are the holocaust of humanity; if philosophy can be the instant sunlight to their endless vampirism, it will save more lives than all the doctors who have ever lived.

If someone was going to kill someone dear to you, and you could stop that person by killing them instead, would you kill them, knowing it was an effective way to save your loved one?

I would rather go out of politics having the feeling that I had done what was right than stay in with the approval of all men, knowing in my heart that I have acted as I ought not to.

The word "good" has many meanings. For example, if a man were to shoot his grandmother at a range of five hundred yards, I should call him a good shot, but not necessarily a good man.

If it is true that we cannot possess knowledge of what is good in any absolute sense, it is equally true that we have an ethical duty to decide between what is better and what is worse.

Science, as long as it limits itself to the descriptive study of the laws of nature, has no moral or ethical quality and this applies to the physical as well as the biological sciences.

If you don't have integrity, you have nothing. You can't buy it. You can have all the money in the world, but if you are not a moral and ethical person, you really have nothing.

Every skill and every inquiry, and similarly every action and rational choice, is thought to aim at some good; and so the good had been aptly described as that at which everything aims.

I will call no being good who is not what I mean when I apply that epithet to my fellow creatures; and if such a creature can sentence me to hell for not so calling him, to hell I will go .
