The game of science is, in principle, without end. He who decides one day that scientific statements do not call for any further test, and that they can be regarded as finally verified, retires from the game.

When even the dictators of today appeal to reason, they mean that they possess the most tanks. They were rational enough to build them; others should be rational enough to yield to them.

To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it. Then give up deceiving people; confess ignorance of what you don't know, and leave everyone to form his own articles of faith for himself. Perhaps they won't turn out so bad, especially as they'll rub one another's corners down, and mutually rectify mistakes. The existence of many views will at any rate lay a foundation of tolerance. Those who possess knowledge and capacity may betake themselves to the study of philosophy, or even in their own persons carry the history of philosophy a step further.

Nothing is so fatiguing as the eternal hanging on of an uncompleted task.

With an ill-famed man form no connection.

Bourgeois society is ruled by equivalence. It makes the dissimilar comparable by reducing it to abstract quantities. To the Enlightenment, that which does not reduce to numbers, and ultimately to the one, becomes illusion.

What I give is the morphology of the use of an expression. I show that it has kinds of uses of which you had not dreamed. In philosophy one feels forced to look at a concept in a certain way. What I do is suggest, or even invent, other ways of looking at it. I suggest possibilities of which you had not previously thought. You thought that there was one possibility, or only two at most. But I made you think of others. Furthermore, I made you see that it was absurd to expect the concept to conform to those narrow possibilities. Thus your mental cramp is relieved, and you are free to look around the field of use of the expression and to describe the different kinds of uses of it.

Neither did the dispensation of God vary in the times after our Saviour came into the world; for our Saviour himself did first show His power to subdue ignorance, by His conference with the priests and doctors of the law, before He showed His power to subdue nature by His miracles. And the coming of this Holy Spirit was chiefly figured and expressed in the similitude and gift of tongues, which are but vehicula scientiæ.

The thought of being under absolute compulsion, the plaything of another, is unendurable for a human being. Hence, if every way of escape from the constraint is taken from him, there is nothing left for him to do but to persuade himself that he does the things he is forced to do willingly, that is to say, to substitute devotion for obedience. ... It is by this twist that slavery debases the soul: this devotion is in fact based on a lie, since the reasons for it cannot bear investigation. ... Moreover, the master is deceived too by the fallacy of devotion.

I have lived in the pursuit of a vision, both personal and social. Personal: to care for what is noble, for what is beautiful, for what is gentle; to allow moments of insight to give wisdom at more mundane times. Social: to see in imagination the society that is to be created, where individuals grow freely, and where hate and greed and envy die because there is nothing to nourish them. These things I believe, and the world, for all its horrors, has left me unshaken.

Music is associated not only with speculation but with morality. When rhythms and modes reach an intellect through the ear, they doubtless affect and reshape that mind according to their particular character.

The Quaestor turned back the pages until he found himself among the Pensées. "We are not satisfied," he read, "with the life we have in ourselves and our own being; we want to live an imaginary life in other people's idea of us. Hence all our efforts are directed to seeming what we are not. We labor incessantly to preserve and embellish this imaginary being, and neglect that which is really ours." The Quaestor put down the book, ... and ruefully reflected that all his own troubles had arisen from this desire to seem what in fact he was not. To seem a man of action, when in fact he was a contemplative; to seem a politician, when nature had made him an introspective psychologist; to seem a wit, which God had intended him for a sage.

The law of the table is beauty, a respect to the common soul of the guests. Everything is unreasonable which is private to two or three, or any portion of the company. Tact never violates for a moment this law; never intrudes the orders of the house, the vices of the absent, or a tariff of expenses, or professional privacies; as we say, we never "talk shop" before company. Lovers abstain from caresses, and haters from insults, while they sit in one parlor with common friends.

In the state of nature, wrong-doing is impossible ; or, if anyone does wrong, it is to himself, not to another. For no one by the law of nature is bound to please another, unless he chooses, nor to hold anything to be good or evil, but what he himself, according to his own temperament, pronounces to be so ; and, to speak generally, nothing is forbidden by the law of nature, except what is beyond everyone's power.

Money does not arise by convention, any more than the state does. It arises out of exchange, and arises naturally out of exchange; it is a product of the same.

Making money is not without its value, but nothing is baser than to make it by wrong-doing.

It is a serious question among them whether they [Africans] are descended from monkeys or whether the monkeys come from them. Our wise men have said that man was created in the image of God. Now here is a lovely image of the Divine Maker: a flat and black nose with little or hardly any intelligence. A time will doubtless come when these animals will know how to cultivate the land well, beautify their houses and gardens, and know the paths of the stars: one needs time for everything.

He felt neither guilt nor distress at the pleasure with which he was now filled by the proximity of this young creature, and when he discovered in himself even physical symptoms of his inclination he did not take fright, but continued cheerfully and serenely to see Nick whenever the ordinary run of his duties suggested it, congratulating himself upon the newly achieved solidity and rational calm of his spiritual life.

The highest and ultimate personality values are declared to be independent of contrasts like rich and poor, healthy and sick, etc. The world had become accustomed to considering the social hierarchy, based on status, wealth, vital strength, and power, as an exact image of the ultimate values of morality and personality. The only way to disclose the discovery of anew and higher sphere of being and life, of the "kingdom of God" whose order is independent of that worldly and vital hierarchy, was to stress the vanity of the old values in this higher order.

I'm prepared to teach acceptance of religion, but, religion has to agree to the social contract. If we have to do it church by church, I'm ready.

A judgment, for me is not the mere grasping of a thought, but the admission of its truth.

A genuine first-hand religious experience like this is bound to be a heterodoxy to its witnesses, the prophet appearing as a mere lonely madman. If his doctrine prove contagious enough to spread to any others, it becomes a definite and labeled heresy. But if it then still prove contagious enough to triumph over persecution, it becomes itself an orthodoxy; and when a religion has become an orthodoxy, its day of inwardness is over: the spring is dry; the faithful live at second hand exclusively and stone the prophets in their turn. The new church, in spite of whatever human goodness it may foster, can be henceforth counted on as a staunch ally in every attempt to stifle the spontaneous religious spirit, and to stop all later bubblings of the fountain from which in purer days it drew its own supply of inspiration.

A rationalist, as I use the word, is a man who attempts to reach decisions by argument and perhaps, in certain cases, by compromise, rather than by violence. He is a man who would rather be unsuccessful in convincing another man by argument than successful in crushing him by force, by intimidation and threats, or even by persuasive propaganda.

...You could take up the line that some of the gnostics took up - a line which I often thought was a very plausible one - that as a matter of fact this world that we know was made by the devil at a moment when God was not looking. There is a good deal to be said for that, and I am not concerned to refute it.

And yet there is nothing so badly imagined: nature seems to have provided, that the follies of men should be transient, but they by writing books render them permanent. A fool ought to content himself with having wearied those who lived with him: but he is for tormenting future generations; he is desirous that his folly should triumph over oblivion, which he ought to have enjoyed as well as his grave; he is desirous that posterity should be informed that he lived, and that it should be known for ever that he was a fool. Commonly paraphrased as "An author is a fool who, not content with having bored those who have lived with him, insists on boring future generations".

The end cannot justify the means for the simple and obvious reason that the means employed determine the nature of the ends produced.

Riches are a good handmaid, but the worst mistress.

Ireland still remains the Holy Isle whose aspirations must on no account be mixed with the profane class-struggles of the rest of the sinful world ... the Irish peasant must not on any account know that the Socialist workers are his sole allies in Europe.

Ritual society is a society of rules. It is based not on virtues but on a passion for rules.

An intuitionist conception of justice is, one might say, but half a conception.

Historical time knows no lasting present.

The free will, the actual motor of reason in society, necessarily creates wrong. The individual must clash with the social order that claims to represent his own will in its objective form. But the wrong and the 'avenging justice' that remedies it not only expresses a 'higher logical necessity,' but also prepare the transition to a higher social form of freedom, the transition from abstract right to morality. For, in committing a wrong, and in accepting punishment for his deed, the individual becomes conscious of the 'infinite subjectivity' of his freedom. He learns that he is free only as a private person.

My soul, my soul, where are you? Do you hear me? I speak, I call you-are you there? I have returned, here I am again. I have shaken the dust of all the lands from my feet, and I have come to you again, I am with you. After long years of long wandering, I have come to you anew. Shall I tell you everything I have seen, experienced, and drunk in? Or do you not want to hear about all the noise of life and the world? But one thing you must know, the one thing I have learned is that one must live this life. This life is the way, the long sought-after way to the unfathomable, which we call "divine". There is no other way. All other ways are false paths.

Freedom is the greatest of political goods. I do not say freedom is the greatest of all goods: the best things come from within-they are such things as creative art, and love, and thought. Such things can be helped or hindered by political conditions, but not actually produced by them; and freedom is, both in itself and in its relation to these other goods the best thing that political and economic conditions can secure.

I believe in God, although I live very happily with atheists... It is very important not to mistake hemlock for parsley; but not at all so to believe or not in God.

Big industry has brought all the people of the Earth into contact with each other, has merged all local markets into one world market, has spread civilization and progress everywhere and has thus ensured that whatever happens in civilized countries will have repercussions in all other countries. It follows that if the workers in England or France now liberate themselves, this must set off revolution in all other countries - revolutions which, sooner or later, must accomplish the liberation of their respective working class.

If melodiously piping flutes sprang from the olive, would you doubt that a knowledge of flute-playing resided in the olive? And what if plane trees bore harps which gave forth rhythmical sounds? Clearly you would think in the same way that the art of music was possessed by plane trees. Why, then, seeing that the universe gives birth to beings that are animate and wise, should it not be considered animate and wise itself?

I shall develop the thesis that anyone acting communicatively must, in performing any speech act, raise universal validity claims and suppose that they can be vindicated.

For the truth is that our doctrines are usually only the justification a posteriori of our conduct, or else they are our way of trying to explain that conduct to ourselves.

We are all of us in error, the humorists excepted. They alone have discerned, as though in jest, the inanity of all that is serious and even of all that is frivolous.

I look forward to a future when acts of war shall be formally outlawed as between civilized peoples. All these beliefs of mine put me firmly into the anti-military party. But I do not believe that peace either ought to be or will be permanent on this globe, unless the states, pacifically organized, preserve some of the old elements of army-discipline. A permanently successful peace-economy cannot be a simple pleasure-economy. In the more or less socialistic future toward which mankind seems drifting we must still subject ourselves collectively to those severities which answer to our real position upon this only partly hospitable globe. We must make new energies and hardihoods continue the manliness to which the military mind so faithfully clings.

Refinement is a sign of a deficient vitality, in art, in love, and in everything.

If death had only negative aspects, dying would be an unmanageable action.

The voice in my soul in which I will have faith, and for the sake of which I have faith in all else, does not merely command me generally to act, but in every particular situation it declares what I shall do and what leave undone; it accompanies me through every event of my life, and it is impossible for me to contend against it. To listen to it and obey it honestly and impartially, without fear or equivocation, is the business of my existence. My life is no longer an empty I play without truth or significance. It is appointed that what I conscience ordains me shall be done, and for this purpose am I here. I have understanding to know, and power to execute it. By conscience alone comes truth and reality into my representations.

Asceticism is the trifling of an enthusiast with his power, a puerile coquetting with his selfishness or his vanity, in the absence of any sufficiently great object to employ the first or overcome the last.

Among other men Reason awakes in another form-as the impulse towards Personal Freedom, which, although it never opposes the mild rule of the inward Instinct which it loves, yet rises in rebellion against the pressure of a stranger Instinct which has usurped its rights; and in this awakening it breaks the chains,-not of Reason as Instinct itself, but of the Instinct of foreign natures clothed in the garb of external power.

One always speaks badly when one has nothing to say.

I have compassion on the multitude, because they continue with me now three days, and have nothing to eat: and I will not send them away fasting, lest they faint in the way.

Every parting gives a foretaste of death, every reunion a hint of the resurrection.

There is a certain kind of morality which is even more alien to good and evil than amorality is.
