The principal source of the harm done by the State is the fact that power is its chief end.

"Optimism," said Cacambo, "What is that?" "Alas!" replied Candide, "It is the obstinacy of maintaining that everything is best when it is worst!

Reason is like an open secret that can become known to anyone at any time; it is the quiet space into which everyone can enter through his own thought.

What the horrors of war are, no one can imagine - they are not wounds and blood and fever, spotted and low, or dysentery, chronic and acute, cold and heat and famine - they are intoxication, drunken brutality, demoralization and disorder on the part of the inferior, jealousies, meanness, indifference, selfish brutality on the part of the superior.

We are speaking on this occasion, not as members of this or that nation, continent, or creed, but as human beings, members of the species Man, whose continued existence is in doubt.

... in such a matter he would never have been guided by his first thoughts (which would probably have been right) nor even by his twenty-first (which would have at least been explicable). Beyond doubt he would have prolonged deliberation till his hundred-and-first; and they would be infallibly and invincibly wrong. This is what always happens to the deliberations of a simple man who thinks he is a subtle one.

In the process of decision those alternatives are chosen which are considered to be appropriate means of reaching desired ends. Ends themselves, however, are often merely instrumental to more final objectives. We are thus led to the conception of a series, or hierarchy, of ends. Rationality has to do with the construction of means-ends chains of this kind.

It is sweet and honorable to die for one's country.

I am not bound over to swear allegiance to any master; where the storm drives me I turn in for shelter.

Everything is a subject on which there is not much to be said.

Most of the luxuries, and many of the so-called comforts of life, are not only not indispensable, but positive hindrances to the elevation of mankind.

Rationalism is an adventure in the clarification of thought.

Nothing more strikingly betrays the credulity of mankind than medicine. Quackery is a thing universal, and universally successful. In this case it becomes literally true that no imposition is too great for the credulity of men.

But if ether is nothing but an hypothesis explanatory of light, air on the other hand, is a thing that is directly felt; and even if it did not enable us to explain the phenomenon of sound, we should nevertheless always be directly aware of it, and above all, of the lack of it in moments of suffocation or air-hunger. And in the same way God Himself, not the idea of God, may become a reality that is immediately felt; and even though the idea of God does not enable us to explain either the existence or essence of the Universe, we have at times the direct feeling of God, above all in moments of spiritual suffocation. And the feeling, mark it well, for all that is tragic in it and the whole tragic sense of life is founded upon this - this feeling is a feeling of hunger for God, of the lack of God. To believe in God is, in the first instance... to wish that there may be a God, to be unable to live without Him.

The least initial deviation from the truth is multiplied later a thousandfold.

He that denies any of the doctrines that Christ has delivered, to be true, denies him to be sent from God, and consequently to be the Messiah; and so ceases to be a Christian.

Ordinary language is totally unsuited for expressing what physics really asserts, since the words of everyday life are not sufficiently abstract. Only mathematics and mathematical logic can say as little as the physicist means to say.

Government has no other end than the preservation of property.

If we love God while thinking that he does not exist, he will manifest his existence.

A person is strong only when he stands upon his own truth, when he speaks and acts from his deepest convictions. Then, whatever the situation he may be in, he always knows what he must say and do. He may fall, but he cannot bring shame upon himself or his cause. If we seek the liberation of the people by means of a lie, we will surely grow confused, go astray, and lose sight of our objective, and if we have any influence at all on the people we will lead them astray as well - in other words, we will be acting in the spirit of reaction and to its benefit.

By the removal of the unnecessary mouths, and by extracting from the farmer the full value of the farm, a greater surplus, or what is the same thing, the price of a greater surplus, was obtained for the proprietor...

Neither perception nor true opinion, nor reason or explanation combined with true opinion could be knowledge. Then our art of midwifery declare to us that all the offspring that have been born are mere wind-eggs and not worth rearing and if you remain barren, you will be less harsh and gentler to your associates, for you will have the wisdom not to think you know that which you do not know.

If a false thought is so much as expressed boldly and clearly, a great deal has already been gained.

The surface of American society is covered with a layer of democratic paint, but from time to time one can see the old aristocratic colours breaking through.

An extra-terrestrial philosopher, who had watched a single youth up to the age of twenty-one and had never come across any other human being, might conclude that it is the nature of human beings to grow continually taller and wiser in an indefinite progress towards perfection; and this generalisation would be just as well founded as the generalisation which evolutionists base upon the previous history of this planet.

For he who is unmusical is a child in music; he who is without letters is a child in learning; he who is untaught, is a child in life.

What the history of Philosophy shows us is a succession of noble minds, a gallery of heroes of thought, who, by the power of reason, have penetrated into the being of things, of nature and of spirit, into the Being of God, and have won for us by their labours the highest treasure, the treasure of reasoned knowledge.

An untempted woman cannot boast of her chastity.

When the slave auctioneer asked in what he was proficient, he replied, "In ruling people."

It is impossible to imagine a more dramatic and horrifying combination of scientific triumph with political and moral failure than has been shown to the world in the destruction of Hiroshima. From the scientific point of view, the atomic bomb embodies the results of a combination of genius and patience as remarkable as any in the history of mankind.

There is an artist imprisoned in each one of us. Let him loose to spread joy everywhere.

A son is a mirror in which the father sees himself reflected, and the father is a mirror in which the son sees himself as he will be in the future.

When capitalism is negated, social processes no longer stand under the rule of blind natural laws.

The past is the luxury of proprietors.

Recalling all the erroneous things that doctors have been able to say about sex or madness does us a fat lot of good. I think that what is currently politically important is to determine the regime of verediction established at a given moment ... on the basis of which you can now recognize, for example, that doctors in the nineteenth century said so many stupid things about sex. ... It is not so much the history of the true or the history of the false as the history of verediction which has a political significance.

As all those have shown who have discussed civil institutions, and as every history is full of examples, it is necessary to whoever arranges to found a Republic and establish laws in it, to presuppose that all men are bad and that they will use their malignity of mind every time they have the opportunity; and if such malignity is hidden for a time, it proceeds from the unknown reason that would not be known because the experience of the contrary had not been seen, but time, which is said to be the father of every truth, will cause it to be discovered.

Remember that time slurs over everything, let all deeds fade, blurs all writings and kills all memories. Except are only those which dig into the hearts of men by love.

One could count on one's fingers the number of scientists in the entire world who have a general idea of the history and development of their own particular science; there is not one who is really competent as regards sciences other than his own. As science forms an indivisible whole, one may say that there are no longer, strictly speaking, any scientists, but only drudges doing scientific work. . . .

Both of us victims of the same twentieth-century plague. Not the Black Death, this time; the Grey Life.

The goal of maximizing the welfare of all may be better achieved by an ethic that accepts our inclinations and harnesses them so that, taken as a whole, the system works to everyone's advantage.

The music that can deepest reach, And cure all ill, is cordial speech.

I would take to be quite a fool any man who would make a book full of laws and statutes for an apple tree telling it how to bear apples and not thorns, when the tree is able by its own nature to do this better than the man with all his books can describe and demand.

In the name of national security, the Commission's hearings were held in secret, thereby continuing the policy which has marked the entire course of the case. This prompts my second question: If, as we are told, Oswald was the lone assassin, where is the issue of national security? Indeed, precisely the same question must be put here as was posed in France during the Dreyfus case: If the Government is so certain of its case, why has it conducted all its inquiries in the strictest secrecy? "

Every philosophical, ethical, and political idea-its lifeline connecting it with its historical origins having been severed-has a tendency to become the nucleus of a new mythology, and this is one of the reasons why the advance of enlightenment tends at certain points to revert to superstition and paranoia. The majority principle ... has become the sovereign force to which thought must cater. It is a new god, not in the sense in which the heralds of the great revolutions conceived it, namely, as a power of resistance to existing injustice, but as a power of resistance to anything that does not conform.

On reaching Athens he fell in with Antisthenes. Being repulsed by him, because he never welcomed pupils, by sheer persistence Diogenes wore him out. Once when he stretched out his staff against him, the pupil offered his head with the words, "Strike, for you will find no wood hard enough to keep me away from you, so long as I think you've something to say."

I entered the [Communist] Party because its cause was just and I will leave it when it ceases to be just.

"...the church of England, when she baptizes any one, makes him not a Christian [...] the church of England is mistaken, and makes none but socinians Christians"

You don't have a soul. You are a soul. You have a body.

The welfare of the people in particular has always been the alibi of tyrants, and it provides the further advantage of giving the servants of tyranny a good conscience. It would be easy, however, to destroy that good conscience by shouting to them: if you want the happiness of the people, let them speak out and tell what kind of happiness they want and what kind they don't want! But, in truth, the very ones who make use of such alibis know they are lies; they leave to their intellectuals on duty the chore of believing in them and of proving that religion, patriotism, and justice need for their survival the sacrifice of freedom.
