The application of algebra to geometry... far more than any of his metaphysical speculations, has immortalized the name of Descartes, and constitutes the greatest single step ever made in the progress of the exact sciences.

In the spiritual realm nothing is indifferent: what is not useful is harmful.

The selfish gene theory is Darwin's theory, expressed in a way that Darwin did not choose but whose aptness, I should like to think, he would instantly have recognized and delighted in. It is in fact a logical outgrowth of orthodox neo-Darwinism, but expressed as a novel image. Rather than focus on the individual organism, it takes a gene's eye view of nature. It is a different way of seeing, not a different theory.

"He who exalts himself shall be humbled; and he who humbles himself shall be exalted." (Matthew 23:12) The person who exalts himself ... will be humbled, because a person who considers himself to be good, intelligent, and kind will not even try to become better, smarter, kinder. The humble person will be exalted, because he considers himself bad and will try to become better, kinder, and more reasonable.

Every ideology is contrary to human psychology.

People almost invariably arrive at their beliefs not on the basis of proof but on the basis of what they find attractive.

No man is liberated from fear who dare not see his place in the world as it is; no man can achieve the greatness of which he is capable until he has allowed himself to see his own littleness.

Come the Day of Judgment, some believe that the body will be different from our present body. This is only transient, that will be eternal. For this also there are religious arguments.

Be not afraid of life. Believe that life is worth living, and your belief will help create the fact.

There is not a negro from the coast of Africa who does not, in this respect, possess a degree of magnanimity which the soul of his sordid master is too often scarce capable of conceiving. Fortune never exerted more cruelly her empire over mankind, than when she subjected those nations of heroes to the refuse of the jails of Europe, to wretches who possess the virtues neither of the countries which they come from, nor of those which they go to, and whose levity, brutality, and baseness, so justly expose them to the contempt of the vanquished.

In philosophical anthropology, ... where the subject is man in his wholeness, the investigator cannot content himself, as in anthropology as an individual science, with considering man as another part of nature and with ignoring the fact that he, the investigator, is himself a man and experiences this humanity in his inner experience in a way that he simply cannot experience any part of nature.

Oceans of horse-hair, continents of parchment, and learned-sergeant eloquence, were it continued till the learned tongue wore itself small in the indefatigable learned mouth, cannot make unjust just.

What is obscene about pornography is not an excess of sex, but the fact that it contains no sex at all.

A constellation of the most pedantic, obstinate ignorance and presumption, mixed with a kind of rustic incivility, which would try the patience of Job.

The laws of conscience, which we pretend to be derived from nature, proceed from custom.

The plebeian must expect to find himself neglected and despised in proportion as he is remiss in cultivation the objects of esteem; the lord will always be surrounded with sycophants and slaves. The lord therefore has no motive to industry and exertion; no stimulus to rouse him from the lethargic 'oblivious pool', out of which every human intellect originally arose.

Between ourselves and our real natures we interpose that wax figure of idealizations and selections which we call our character.

Only a man who is at one with the world can be at one with himself.

The more man meditates upon good thoughts, the better will be his world and the world at large.

Hope is the only good that is common to all men; those who have nothing else possess hope still.

Since it is difficult to approve the reasons people invoke, each time we leave one of our 'fellow men', the question which comes to mind is invariably the same: how does he keep from killing himself?

Personally, people know themselves very poorly.

And, oddly enough, even at times when the current style permitted a treatment of the less epileptic aspects of religion, no fully adequate rendering of the contemplative life was ever achieved in the plasdc arts of Christendom. The peace that passes all understanding was often sung and spoken; it was hardly ever painted or carved. Thus, in the writings of St. Bernard, of Albertus Magnus, of Eckhart and Tauler and Ruysbroeck one may find passages that express very clearly the nature and significance of mystical contemplation. But the saints who figure in medieval painting and sculpture tell us next to nothing about this anticipation of the beatific vision. There are no equivalents of those Far Eastern Buddhas and Bodhisattvas who incarnate, in stone and paint, the experience of ultimate reality.

It is true that in the confessional it is the pastor who preaches; but the true preacher is still the secret-sharer in your inner being. The pastor can preach only in vague generalities; the preacher in your inner being is just the opposite; he speaks simply and solely about you, to you, and within you.

A great prison structure was planned, whose different levels would correspond exactly to the levels of the centralized administration. The scaffold, where the body of the tortured criminal had been exposed to the ritually manifested force of the sovereign, the punitive theatre in which the representation of punishment was permanently available to the social body, was replaced by a great enclosed, complex and hierarchized structure that was integrated into the very body of the state apparatus.

But it is not to be conceived that mere mechanical causes could give birth to so many regular motions: since the Comets range over all parts of the heavens, in very eccentric orbits. For by that kind of motion they pass easily through the orbs of the Planets, and with great rapidity; and in their aphelions, where they move the slowest, and are detain'd the longest, they recede to the greatest distances from each other, and thence suffer the least disturbance from their mutual attractions.

Just as we teach children to avoid being destroyed by motor cars if they can, so we should teach them to avoid being destroyed by cruel fanatics, and to this end we should seek to produce independence of mind, somewhat sceptical and wholly scientific, and to preserve, as far as possible, the instinctive joy of life that is natural to healthy children. This is the task of a liberal education: to give a sense of the value of things other than domination, to help create wise citizens of a free community, and through the combination of citizenship with liberty in individual creativeness to enable men to give to human life that splendour which some few have shown that it can achieve.

The less somebody knows and understands himself the less great he is, however great may be his talent. For this reason our scientists are not great.

I see your vile implication. My only explanation for it is that you are criminally insane.

Weisinger, a couple of years ago, made up the following story: "Isaac Asimov was asked how Superman could fly faster than the speed of light, which was supposed to be an absolute limit. To this Asimov replied, 'That the speed of light is a limit is a theory; that Superman can travel faster than light is a fact.'"

Who is this that cries from the ends of the earth? Who is this one man who reaches to the extremities of the universe? He is one, but that one is unity. He is one, not one in a single place, but the cry of this one man comes from the remotest ends of the earth. But how can this one man cry out from the ends of the earth, unless he be one in all?

What most people in our culture mean by being lovable is essentially a mixture between being popular and having sex appeal.

Woe unto you, lawyers! for ye have taken away the key of knowledge: ye entered not in yourselves, and them that were entering in ye hindered. And as he said these things unto them, the scribes and the Pharisees began to urge him vehemently, and to provoke him to speak of many things: Laying wait for him, and seeking to catch something out of his mouth, that they might accuse him.

Whether, then, all ought not immediately to discontinue and renounce it, with grief and abhorrence? Should not every society bear testimony against it, and account obstinate persisters in it bad men, enemies to their country, and exclude them from fellowship; as they often do for much lesser faults?

My principal motive is the belief that we can still make admirable sense of our lives even if we cease to have ... "an ambition of transcendence."

In the present state of society it appears necessary to go back to first principles in search of the most simple truths, and to dispute with some prevailing prejudice every inch of ground. To clear my way, I must be allowed to ask some plain questions, and the answers will probably appear as unequivocal as the axioms on which reasoning is built; though, when entangled with various motives of action, they are formally contradicted either by the words or conduct of men.

When Christianity came into the world the task was simply to proclaim Christianity. The same is the case wherever Christianity is introduced into a country the religion of which is not Christianity.

Of course a war is entertaining. The immediate fear and suffering of the humans is a legitimate and pleasing refreshment for our myriads of toiling workers. But what permanent good does it do us unless we make use of it for bringing souls to Our Father Below? When I see the temporal suffering of humans who finally escape us, I feel as if I had been allowed to taste the first course of a rich banquet and then denied all the rest. It is worse than not to have tasted it at all. The Enemy, true to His barbarous methods of warfare, allows us to see the short misery of His favourites only to tantalize and torment us - to mock the incessant hunger, which, during this present phase of great conflict, His blockade is admittedly imposing.

Our longing to save consciousness, to give personal and human finality to the Universe and to existence, is such that even in the midst of a supreme, an agonizing and lacerating sacrifice, we should still hear the voice that assured us that if our consciousness disappears, it is that the infinite and eternal Consciousness may be enriched thereby, that our souls may serve as a nutriment to the Universal soul.

The spirit of a production-centered, commodity-greedy society is such that only the non-conformist can defend himself sufficiently against it. Those who are seriously concerned with love as the only rational answer to the problem of human existence must, then, arrive at the conclusion that important and radical changes in our social structure are necessary, if love is to become a social and not a highly individualistic, marginal phenomenon.

In every man sleeps a prophet, and when he wakes there is a little more evil in the world

For those who want 'to change life", 'to reinvent love,' God is nothing but a hindrance.

A third illusion haunts us, that a long duration, as a year, a decade, a century, is valuable. But an old French sentence says, "God works in moments," - "En peu d'heure Dieu labeure." We ask for long life, but 't is deep life, or grand moments, that signify. Let the measure of time be spiritual, not mechanical. Life is unnecessarily long. Moments of insight, of fine personal relation, a smile, a glance, - what ample borrowers of eternity they are! Life culminates and concentrates; and Homer said, "The Gods ever give to mortals their appointed share of reason only on one day."

Nonviolence is perhaps best described as a practice of resistance that becomes possible, if not mandatory, precisely at the moment when doing violence seems most justified and obvious. In this way, it can be understood as a practice that not only stops a violent act, or a violent process, but requires a form of sustained action, sometimes aggressively pursued. So, one suggestion I will make is that we can think of nonviolence not simply as the absence of violence, or as the act of refraining from committing violence, but as a sustained commitment, even a way of rerouting aggression for the purposes of affirming ideals of equality and freedom.

We had nothing to say to one another, and while I was manufacturing my phrases I felt that earth was falling through space and that I was falling with it at a speed that made me dizzy.

Religion in most countries, more or less in every country, is no longer what it was, and should be,-a thousand-voiced psalm from the heart of Man to his invisible Father, the fountain of all Goodness, Beauty, Truth, and revealed in every revelation of these; but for the most part, a wise prudential feeling grounded on mere calculation; a matter, as all others now are, of Expediency and Utility; whereby some smaller quantum of earthly enjoyment may be exchanged for a far larger quantum of celestial enjoyment. Thus Religion too is Profit, a working for wages; not Reverence, but vulgar Hope or Fear.

The other big issue is an emotional one. We tend to feel the greatest bonds of solidarity with people that are close to us. There are very few true citizens of the world. We're citizens of individual countries and we really feel the closest bonds to people that live within our nation, and therefore... the nation becomes a kind of social glue. But if you're going to make a national identity compatible with liberalism, it has to be the right kind of national identity. It has to be one that is open to all of the citizens that actually live in the territory of the nation. It can't exclude certain groups by race, by ethnicity, by religious belief and the like, and therefore it needs to be an open identity that is based on essentially liberal ideas.

Take our politicians: they're a bunch of yo-yos. The presidency is now a cross between a popularity contest and a high school debate, with an encyclopedia of cliches.

People in new environments always produce the new preceptual modality without any difficulty or awareness of change. It is later that the psychic and social realignments baffle societies.
