Follow me, and I will make you fishers of men.

Should I not be proud, when for twenty years I have had to admit to myself that the great Newton and all the mathematicians and noble calculators along with him were involved in a decisive error with respect to the doctrine of color, and that I among millions was the only one who knew what was right in this great subject of nature?

Religion is, as it were, the calm bottom of the sea at its deepest point, which remains calm however high the waves on the surface may be.

What we want is not freedom but its appearances. It is for these simulacra that man has always striven. And since freedom, as has been said, is no more than a sensation, what difference is there between being free and believing ourselves free?

An old proverb fetched from the outward and visible world says: "Only the man that works gets the bread." Strangely enough this proverb does not aptly apply in that world to which it expressly belongs. For the outward world is subjected to the law of imperfection, and again and again the experience is repeated that he too who does not work gets the bread, and that he who sleeps gets it more abundantly than the man who works. In the outward world everything is made payable to the bearer, this world is in bondage to the law of indifference, and to him who has the ring, the spirit of the ring is obedient, whether he be Noureddin or Aladdin, and he who has the world's treasure, has it, however he got it.

Of all forms of caution, caution in love is perhaps the most fatal to true happiness.

I'll know how to die with courage; that is easier than living.

The whole of science is nothing more than a refinement of every day thinking.

Names and attributes must be accommodated to the essence of things, and not the essence to the names, since things come first and names afterwards.

If democracy has become superfluous or annoying to the bourgeoisie, it is on the contrary necessary and indispensable to the working class. It is necessary to the working class because it creates the political forms (autonomous administration, electoral rights, etc.) which will serve the proletariat as fulcrums in its task of transforming bourgeois society. Democracy is indispensable to the working class because only through the exercise of its democratic rights, in the struggle for democracy, can the proletariat become aware of its class interests and its historic task.

We have the greatest admiration for this learned doctor: with what scientific stoicism he walks through the land of wonders, unwondering; like a wise man through some huge, gaudy, imposing Vauxhall, whose fire-works, cascades and symphonies, the vulgar may enjoy and believe in,-but where he finds nothing real but the saltpetre, pasteboard and catgut.

The learning of the gentleman enters through his ears, fastens to his heart, spreads through his four limbs, and manifests itself in his actions. ... The learning of the petty person enters through his ears and passes out his mouth. From mouth to ears is only four inches-how could it be enough to improve a whole body much larger than that?

Marriage is a union between two persons - one man and one woman. A woman who has given herself up to one, can not give herself up to a second, for her whole dignity requires that she should belong only to this one.

Woe to that nation whose literature is disturbed by the intervention of power. Because that is not just a violation against "freedom of print", it is the closing down of the heart of the nation, a slashing to pieces of its memory. The nation ceases to be mindful of itself, it is deprived of its spiritual unity, and despite a supposedly common language, compatriots suddenly cease to understand one another Woe to that nation whose literature is cut short by the intrusion of force. This is not merely interference with freedom of the press but the sealing up of a nation's heart, the excision of its memory.

The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him.

In order to touch the heart and gain the confidence, the assent, the adhesion, and the co-operation of the illiterate legions of the proletariat - and the vast majority of proletarians unfortunately still belong in this category - it is necessary to begin to speak to those workers not of the general sufferings of the international proletariat as a whole but of their particular, daily, altogether private misfortunes. It is necessary to speak to them of their own trade and the conditions of their work in the specific locality where they live; of the harsh conditions and long hours of their daily work, of the small pay, the meanness of their employer, the high cost of living, and how impossible it is for them properly to support and bring up a family.

Man's main task in life is to give birth to himself, to become what he potentially is. The most important product of his effort is his own personality.

I may live for thirty years, or perhaps forty, or maybe just one day: therefore I have resolved to use this day, or whatever I have to say in these thirty years or whatever I have to say this one day I may have to live - I have resolved to use it in such a way that if not one day in my whole past life has been used well, this one by the help of God will be.

Echoing the Christian faith in free will, humanists hold that human beings are - or may someday become - free to choose their lives. They forget that the self that does the choosing has not itself been chosen.

Neoconservatives believed that history can be pushed along with the right application of power and will. Leninism was a tragedy in its Bolshevik version, and it has returned as farce when practiced by the United States. Neoconservatism, as both a political symbol and a body of thought, has evolved into something I can no longer support. ..."War" is the wrong metaphor for the broader struggle, since wars are fought at full intensity and have clear beginnings and endings. Meeting the jihadist challenge is more of a "long, twilight struggle" whose core is not a military campaign but a political contest for the hearts and minds of ordinary Muslims around the world.

Let us pardon him his hope of a vain apocalypse, and of a second coming in great triumph upon the clouds of heaven. Perhaps these were the errors of others rather than his own; and if it be true that he himself shared the general illusion, what matters it, since his dream rendered him strong against death, and sustained him in a struggle to which he might otherwise have been unequal?

In death too, there is always something of the rich cat that lets the mouse run before devouring it.

The ground for taking ignorance to be restrictive of freedom is that it causes people to make choices which they would not have made if they had seen what the realization of their choices involved.

Plagued by Western habits of either-or, dualistic thinking, we all may fail to understand that race, class and gender interconnect to sustain a corporate ruling class. In the language of African-American essayist bell hooks, they are interlocking systems of oppression. Neither Latina nor Anglo women should yield to the temptation of making a hierarchy of oppressions where battles are fought over whether racism is "worse" than sexism, or class oppression is "deeper" than racism, etc. Instead of hierarchies we need bridges which, after all, exist to make two ends meet.

An organised system of machines, to which motion is communicated by the transmitting mechanism from a central automation, is the most developed form of production by machinery.

Whatever is merely positive is lifeless. Negativity is essential to vitality.

And if the immortality of the soul had been unable to find vindication in rational empiricism, neither is it satisfied with pantheism. To say that everything is God, and that when we die, we return to God, or more accurately, continue in Him, avails our longing nothing; for if this indeed be so, then we were in God before we were born, and if we die we return to where we were before being born, then the human soul, the individual consciousness, is perishable. And since we know very well that God, the personal and conscious God of Christian monotheism, is simply the provider, and above all the guarantor, of our immortality, pantheism is said, and rightly said to be merely atheism disguised; and in my opinion, undisguised.

Science seems to be at war with itself.... Naive realism leads to physics, and physics, if true, shows naive realism to be false. Therefore naive realism, if true, is false; therefore it is false.

Machines are worshipped because they are beautiful and valued because they confer power; they are hated because they are hideous and loathed because they impose slavery.

Staying as I am, one foot in one country and the other in another, I find my condition very happy, in that it is free.

A truly powerful holder of power does not simply elicit agreement, but enthusiasm and excitement.

The world is nothing, the man is all; in yourself is the law of all nature, and you know not yet how a globule of sap ascends; in yourself slumbers the whole of Reason; it is for you to know all, it is for you to dare all.

You could leave life right now. Let that determine what you do and say and think.

All the world's not a stage.

Superstition is to religion what astrology is to astronomy, the mad daughter of a wise mother. These daughters have too long dominated the earth.

In regard to man's final end, all the higher religions are in complete agreement. The purpose of human life is the discovery of Truth, the unitive knowledge of the Godhead. The degree to which this unitive knowledge is achieved here on earth determines the degree to which it will be enjoyed in the posthumous state. Contemplation of truth is the end, action the means.

After death the sensation is either pleasant or there is none at all. But this should be thought on from our youth up, so that we may be indifferent to death, and without this thought no one can be in a tranquil state of mind. For it is certain that we must die, and, for aught we know, this very day. Therefore, since death threatens every hour, how can he who fears it have any steadfastness of soul?

The average man's opinions are much less foolish than they would be if he thought for himself: in science, at least, his respect for authority is on the whole beneficial.

Yet it seems extraordinary that the justice of increasing the expectations of the better placed by a billion dollars, say, should turn on whether the prospects of the least favored increase or decrease by a penny.

As an eminent pioneer in the realm of high frequency currents... I congratulate you on the great successes of your life's work.

Often what is absent has more power than what is present.

The three qualities of space and time reciprocally affect and qualify one another in experience. Space is inane save as occupied with active volumes. Pauses are holes when they do not accentuate masses and define figures as individuals. Extension sprawls and finally benumbs if it does not interact with place so as to assume intelligible distribution. Mass is nothing fixed. It contracts and expands, asserts and yields, according to its relations to other spatial and enduring things.... these are then the common properties of the matter of arts because there are general conditions without which an experience is not possible. As we saw earlier, the basic condition is felt relationship between doing and undergoing as the organism and environment interact.

Whether nature gives me a right, or whether God, the people's choice, etc., does so, all of that is the same foreign right, a right that I do not give or take to myself. Thus the Communists say, equal labour entitles man to equal enjoyment. [...] No, equal labour does not entitle you to it, but equal enjoyment alone entitles you to equal enjoyment. Enjoy, then you are entitled to enjoyment. But, if you have laboured and let the enjoyment be taken from you, then - 'it serves you right.' If you take the enjoyment, it is your right; if, on the contrary, you only pine for it without laying hands on it, it remains as before, a, 'well-earned right' of those who are privileged for enjoyment. It is their right, as by laying hands on it would become your right.

Could it be that sexual perversion and romanticism sprang from the same longing for distant horizons?

Those who assert that the mathematical sciences say nothing of the beautiful or the good are in error. For these sciences say and prove a great deal about them; if they do not expressly mention them, but prove attributes which are their results or definitions, it is not true that they tell us nothing about them. The chief forms of beauty are order and symmetry and definiteness, which the mathematical sciences demonstrate in a special degree.

Real culture lives by sympathies and admirations, not by dislikes and disdain - under all misleading wrappings it pounces unerringly upon the human core.

In the performance of an illocutionary act in the literal utterance of a sentence, the speaker intends to produce a certain effect by means of getting the hearer to recognize his intention to produce that effect; and furthermore, if he is using the words literally, he intends this recognition to be achieved in virtue of the fact that the rules for using the expressions he utters associate the expression with the production of that effect.

There will be a time when those trying to turn the world into a Colosseum for their own amusement will be raw meat thrown to the wolves themselves, and the rest of us will watch, as justice is served, with a clean conscience.

I cannot help believing that Mucius was all the more lucky because he manipulated the flames as calmly as if he were holding out his hand to the manipulator. He had wiped out all his previous mistakes; he finished the war unarmed and maimed; and with that stump of a hand he conquered two kings.
