"And the upshot of all this," so I have been told more than once and by more than one person, "will be simply that all you will succeed in doing will be to drive people to the wildest Catholicism." And I have been accused of being a reactionary and even a Jesuit. Be it so! ...I know very well it is madness to seek to turn the waters of the river back to their source, and that it is only the ignorant who seek to find in the past a remedy for their present ills; but I know too that anyone who fights for any ideal whatever, although his ideal may seem to lie in the past, is driving the world on to the future, and that the only reactionaries are those who find themselves at home in the present. Every supposed restoration of the past is a creation of the future, and if the past which it is sought to restore is a dream, something imperfectly known, so much the better.

Great minds are related to the brief span of time during which they live as great buildings are to a little square in which they stand: you cannot see them in all their magnitude because you are standing too close to them.

The repression of liberty that took place in the countries in which Communist regimes were established cannot be adequately explained as a product of backwardness, or of errors in the application of Marxian theory. It was the result of a resolute attempt to realize an Enlightenment utopia - a condition of society in which no serious form of conflict any longer exists.

America is like a large, friendly dog in a very small room. Every time it wags its tail, it knocks over a chair!

Though it is often assumed that naturalism must be hostile to religion, the opposite is true. Enemies of religion think of it as an intellectual error, which humanity will eventually grow out of. It is hard to square this view with Darwinian science - why should religion be practically universal, if it has no evolutionary value?

I had better never see a book than to be warped by its attraction clean out of my own orbit, and made a satellite instead of a system. The one thing in the world, of value, is the active soul.

I want to be seen here in my simple, natural, ordinary fashion, without straining or artifice; for it is myself that I portray...I am myself the matter of my book. To the Reader

There are always two parties, the party of the Past and the party of the Future: the Establishment and the Movement. At times the resistance is reanimated, the schism runs under the world and appears in Literature, Philosophy, Church, State and social customs.

We should desire neither the immortality nor the death of any human being, whoever he may be, with whom we have to do.

Mathematics have a triple aim. They must furnish an instrument for the study of nature. But that is not all: they have a philosophic aim and, I dare maintain, an esthetic aim. They must aid the philosopher to fathom the notions of number, of space, of time. And above all, their adepts find therein delights analogous to those given by painting and music. They admire the delicate harmony of numbers and forms; they marvel when a new discovery opens to them an unexpected perspective; and has not the joy they thus feel the esthetic character, even though the senses take no part therein? Only a privileged few are called to enjoy it fully, it is true, but is not this the case for all the noblest arts?This is why I do not hesitate to say that mathematics deserve to be cultivated for their own sake, and the theories inapplicable to physics as well as the others. Even if the physical aim and the esthetic aim were not united, we ought not to sacrifice either.

Tis the sharpness of our mind that gives the edge to our pains and pleasures.

The reader is the content of any poem or of the language he employs, and in order to use any of these forms, he must put them on.

You contain a trillion copies of a large, textual document written in a highly accurate, digital code, each copy as voluminous as a substantial book. I'm talking, of course, of the DNA in your cells.

The world is the totality of facts, not things.

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...

It may indeed be doubted, whether butcher's meat is any where a necessary of life. Grain and other vegetables, with the help of milk, cheese, and butter, or oil, where butter is not to be had, it is known from experience, can, without any butcher's meat, afford the most plentiful, the most wholesome, the most nourishing, and the most invigorating diet.

Whoever will be free must make himself free. Freedom is no fairy gift to fall into a man's lap. What is freedom? To have the will to be responsible for one's self.

No human being, even the most passionately loved and passionately loving, is ever in our possession.

I believe in Christianity as I believe that the sun has risen. Not only because I see it, but because by it I see everything else.

Truthfulness under oath is, by now, a matter of our civic religion, our relation to our fellow citizens rather than our relation to a nonhuman power.

"The bitterest sorrow that man can know is to aspire to do much and to achieve nothing"... so Herodotus relates that a Persian said to a Theban at a banquet (book ix., chap. xvi.). And it is true. With knowledge and desire we can embrace everything , or almost everything; with the will nothing, or almost nothing. And contemplation is not happiness - no! not if this contemplation implies impotence. And out of this collision between our knowledge and our power pity arises.

Resolve to serve no more, and you are at once freed. I do not ask that you place hands upon the tyrant to topple him over, but simply that you support him no longer; then you will behold him, like a great Colossus whose pedestal has been pulled away, fall of his own weight and break in pieces.

It is therefore, the interest of all, that every one, from birth, should be well educated, physically and mentally, that society may be improved in its character, - that everyone should be beneficially employed, physically and mentally, that the greatest amount of wealth may be created, and knowledge attained, - that everyone should be placed in the midst of those external circumstances that will produce the greatest number of pleasurable sensations, through the longest life, that man may be made truly intelligent, moral and happy, and be thus prepared to enter upon the coming Millennium.

Then we may begin by assuming that there are three classes of men—lovers of wisdom, lovers of honor, lovers of gain?

Ha! to forget. How childish! I feel you in my bones. Your silence screams in my ears. You may nail your mouth shut, you may cut out your tongue, can you keep yourself from existing? Will you stop your thoughts.

Rejoice in the things that are present; all else is beyond thee.

You need to know enough of the natural sciences so that you are not a stranger in the world.

There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."

A whale is not a fish in natural history, but it is a fish in commerce and law. A plea that human laws which mention fish do not apply to whales, would be rejected at once by an intelligent judge.

When you write a short story ... you had better know the ending first. The end of a story is only the end to the reader. To the writer, it's the beginning. If you don't know exactly where you're going every minute you're writing, you'll never get there or anywhere.

"He is a slave." His soul, however, may be that of a freeman. "He is a slave." But shall that stand in his way? Show me a man who is not a slave; one is a slave to lust, another to greed, another to ambition, and all men are slaves to fear.

The aged are cared for until death; adults are employed in jobs that make full use of their abilities; and children are nourished, educated, and fostered;...orphans... the disabled and the diseased are all well taken care of....

And above all, we must feel and act as if an endless continuation of our earthly life awaited us after death; and if it be that nothingness is the fate that awaits us we must not, in the words of Obermann, so act that it shall be a just fate.

What would life be without arithmetic, but a scene of horrors?

It has never been in my power to study anything, - mathematics, ethics, metaphysics, gravitation, thermodynamics, optics, chemistry, comparative anatomy, astronomy, psychology, phonetics, economics, the history of science, whist, men and women, wine, metrology, except as a study of semeiotic.

Love is of all the passions the strongest, for it attacks simultaneously the head, the heart, and the body.

Why? Surely they can find other men. Russell's reply when asked "if it wasn't unkind of him to love and leave so many women";

Hegel made famous his aphorism that all the rational is real and all the real rational; but there are many of us who, unconvinced by Hegel, continue to believe that the real, the really real, is irrational, that reason builds upon irrationalities. Hegel, a great framer of definitions, attempted with definitions to reconstruct the universe, like that artillery sergeant who said that cannon were made by taking a hole and enclosing it with steel.

If we are going to be destroyed by an atomic bomb, let that bomb when it comes find us doing sensible and human things - praying, working, teaching, reading, listening to music, bathing the children, playing tennis, chatting to our friends over a pint and a game of darts - not huddled together like frightened sheep and thinking about bombs. They might break our bodies (a microbe can do that) but they need not dominate our minds.

May it be to the world, what I believe it will be, (to some parts sooner, to others later, but finally to all), the signal of arousing men to burst the chains under which monkish ignorance and superstition had persuaded them to bind themselves, and to assume the blessings and security of self-government.

The Idea of Cause is expressed for purposes of science by these three Axioms:-'Every Event must have a Cause':-'Causes are measured by their Effects':-'Reaction is equal and opposite to Action'.

The content or time-clothing of any medium or culture is the preceding medium or culture.

To ignore the true God is in fact only half an evil; atheism is worth more than the piety bestowed on mythical gods.

The difficulty in our education up till now lies, for the most part, in the fact that knowledge did not refine itself into will, to application of itself, to pure practice. The realists felt the need and supplied it, though in a most miserable way, by cultivating idea-less and fettered "practical men." Most college students are living examples of this sad turn of events. Trained in the most excellent manner, they go on training; drilled they continue drilling.

He sleeps well who knows not that he sleeps ill.
