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

I would have written a shorter letter, but I did not have the time.

Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.

Heretics cannot themselves appear good unless they depict the Church as evil, false, and mendacious. They alone wish to be esteemed as the good, but the Church must be made to appear evil in every respect.

Sex-appeal is the keynote of our whole civilization.

Self-alienation is the source of all degradation as well as, on the contrary, the basis of all true elevation. The first step will be a look inward, an isolating contemplation of our self. Whoever remains standing here proceeds only halfway. The second step must be an active look outward, an autonomous, determined observation of the outer world. 

Human rights are not just cultural or legal constructions, as fashionable western relativists are fond of claiming. They are universal values. To deny the benefits of the new regime of rights to other cultures is to patronise them in a way that is reminiscent of the colonial era. If the new regime on torture is good enough for the US, who can say that it is not good for everyone?

War is the father and king of all, and has produced some as gods and some as men, and has made some slaves and some free.

I ... understand why the saints were rarely married women. I am convinced it has nothing inherently to do, as I once supposed, with chastity or children. It has primarily to do with distractions ... Women's normal occupations in general run counter to creative life, or contemplative life or saintly life.

Feeling does not succeed in converting consolation into truth, nor does reason succeed in converting truth into consolation.

... it may be hoped that the white population of the world will soon cease to increase. The Asiatic races will be longer, and the negroes still longer, before their birth rate falls sufficiently to make their numbers stable without help of war and pestilence. But it is to be hoped that the religious prejudices which have hitherto hampered the spread of birth control will die out, and that ... the whole world will learn not to be unduly prolific. Until that happens, the benefits aimed at by socialism can only be partially realized, and the less prolific races will have to defend themselves against the more prolific by methods which are disgusting even if they are necessary.

Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.

They call, in fact, for the forfeiture, to a greater or less degree, of human liberty, to the point where, were I to attempt to sum up what socialism is, I would say that it was simply a new system of serfdom.

As for the commercial business, I can no longer make head or tail of it. At one moment crisis seems imminent and the City prostrated, the next everything is set fair. I know that none of this will have any impact on the catastrophe.

This world is empty to him alone who does not understand how to direct his libido towards objects, and to render them alive and beautiful for himself, for Beauty does not indeed lie in things, but in the feeling that we give to them.

The evolutionary urge drives man to seek for intenser forms of fulfillment, since his basic urge is for more life, more consciousness, and this contentment has an air of stagnation that the healthy mind rejects. (This recognition lies at the centre of my own 'outsider theory': that there are human beings to whom comfort means nothing, but whose happiness consists in following an obscure inner-drive, an 'appetite for reality'.)

I believe most people are aware of periods in their lives when they seem to be "in grace" and other periods when they feel "out of grace," even though they may use different words to describe these states. In the first happy condition, one seems to carry all one's tasks before one lightly, as if borne along on a great tide; and in the opposite state one can hardly tie a shoe-string. It is true that a large part of life consists in learning a technique of tying the shoe-string, whether one is in grace or not. But there are techniques of living too; there are even techniques in the search for grace.

Self-education is, I firmly believe, the only kind of education there is.

Inquiry into the evidence of a doctrine is not to be made once for all, and then taken as finally settled. It is never lawful to stifle a doubt; for either it can be honestly answered by means of the inquiry already made, or else it proves that the inquiry was not complete. "But," says one, "I am a busy man; I have no time for the long course of study which would be necessary to make me in any degree a competent judge of certain questions, or even able to understand the nature of the arguments." Then he should have no time to believe.

In the history of madness, two events signal this change with singular clarity: in 1657, the founding of the Hôpital Général, and the Great Confinement of the poor; and in 1794, the liberation of the mad in chains at Bicêtre. Between these two singular and symmetrical events, something happened, whose ambiguity has perplexed historians of medicine: blind repression in an absolutist regime, according to some, and, according to others, the progressive discovery, by science and philanthropy, of madness in its positive truth. In fact, beneath these reversible meanings, a structure was taking shape, which did not undo that ambiguity but was decisive for it. This structure explains the passage from the medieval and humanist experience of madness to the experience that is our own, which confines madness in mental illness.

I am for freedom of religion, & against all maneuvres to bring about a legal ascendancy of one sect over another, for freedom of the press, and against all violations of the Constitution to silence by force and not by reason the complaints or criticisms, just or unjust, of our citizens against the conduct of their agents.

In conclusion, then, no satisfactory interpretation of quantum mechanics exists today. The questions posed by the confrontation between the Copenhagen interpretation and the hidden variable theorists go to the very foundations of microphysics, but the answers given by hidden variable theorists and Copenhagenists are alike unsatisfactory. Human curiosity will not rest until those questions are answered, but whether they will be answered by conceptual innovations within the framework of the present theory or only within the framework of an as yet unforeseen theory is unknown. The first step toward answering them has been attempted here. It is the modest but essential step of becoming clear on the nature and magnitude of the difficulties.

Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness, Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.

The ceaseless labour of your life is to build the house of death.

He who knows only his own side of the case, knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side; if he does not so much as know what they are, he has no ground for preferring either opinion.

In a well worn metaphor, a parallel is drawn between the life of man and the metamorphosis of the caterpillar into the butterfly; but the comparison may be more just as well as more novel, if for its former term we take the mental progress of the race. History shows that the human mind, fed by constant accessions of knowledge, periodically grows too large for its theoretical coverings, and bursts them asunder to appear in new habiliments, as the feeding and growing grub, at intervals, casts its too narrow skin and assumes another, itself but temporary. Truly the imago state of Man seems to be terribly distant, but every moult is a step gained, and of such there have been many.

If thou shalt aspire after the glorious acts of men, thy working shall be accompanied with compunction and strife, and thy remembrance followed with distaste and upbraidings; and justly doth it come to pass towards thee, O man, that since thou, which art God's work, doest him no reason in yielding him well-pleasing service, even thine own works also should reward thee with the like fruit of bitterness.

Though I certainly deserve no ill treatment from mortals, yet if the insults and repulses I receive were attended with any advantage to them, I would content myself with lamenting in silence my own unmerited indignities and man's injustice.

Those animals which are incapable of making binding agreements with one another not to inflict nor suffer harm are without either justice or injustice; and likewise for those peoples who either could not or would not form binding agreements not to inflict nor suffer harm.

There is a greatness in the lives of those who build up religious systems, a greatness in action, in idea and in self-subordination, embodied in instance after instance through centuries of growth. There is a greatness in the rebels who destroy such systems: they are the Titans who storm heaven, armed with passionate sincerity. It may be that the revolt is the mere assertion by youth of its right to its proper brilliance, to that final good of immediate joy. Philosophy may not neglect the multifariousness of the world - the fairies dance, and Christ is nailed to the cross.

A habit of basing convictions upon evidence, and of giving to them only that degree of certainty which the evidence warrants, would, if it became general, cure most of the ills from which the world is suffering. But at present, in most countries, education aims at preventing the growth of such a habit, and men who refuse to profess belief in some system of unfounded dogmas are not considered suitable as teachers of the young.

Time is a sort of river of passing events, and strong is its current; no sooner is a thing brought to sight than it is swept by and another takes its place, and this too will be swept away.

The Master said, "Hard is it to deal with him, who will stuff himself with food the whole day, without applying his mind to anything good! Are there not gamesters and chess players? To be one of these would still be better than doing nothing at all.

The great and inspiring aims of the Revolution became so clouded with and obscured by the methods used by the ruling political power that it was hard to distinguish what was temporary means and what final purpose. Psychologically and socially the means necessarily influence and alter the aims. The whole history of man is continuous proof of the maxim that to divest one's methods of ethical concepts means to sink into the depths of utter demoralization. In that lies the real tragedy of the Bolshevik philosophy as applied to the Russian Revolution. May this lesson not be in vain.

The absolute justice of the system of things is as clear to me as any scientific fact. The gravitation of sin to sorrow is as certain as that of the earth to the sun, and more so-for experimental proof of the fact is within reach of us all-nay, is before us all in our own lives, if we had but the eyes to see it.

The sun will be darkened, and the moon will not give its light; the stars will fall from the sky, and the heavenly bodies will be shaken. They will see the Son of Man coming on the clouds of the sky, with power and great glory... I tell you the truth, this generation will certainly not pass away until all these things have happened.

On the whole, a man who denies the existence of the effects arranged according to the causes in the question of arts, or whose wisdom cannot understand it, then he has no knowledge of the art of its Maker.

Thus, all unknown quantities can be expressed in terms of a single quantity, whenever the problem can be constructed by means of circles and straight lines, or by conic sections, or even by some other curve of degree not greater than the third or fourth.But I shall not stop to explain this in more detail, because I should deprive you of the pleasure of mastering it yourself, as well as of the advantage of training your mind by working over it, which is in my opinion the principal benefit to be derived from this science. Because, I find nothing here so difficult that it cannot be worked out by anyone at all familiar with ordinary geometry and with algebra, who will consider carefully all that is set forth in this treatise.

To live each day as though one's last, never flustered, never apathetic, never attitudinizing - here is perfection of character.

When a war breaks out, people say: "It's too stupid; it can't last long." But though the war may well be "too stupid," that doesn't prevent its lasting. Stupidity has a knack of getting its way; as we should see if we were not always so much wrapped up in ourselves.

As to the viciousness of the philosophers, the meaning of this complaint is succinctly expressed in the charge that the philosophers do not "hold the gods the city holds." And this accusation is most true. The quest for wisdom begins in doubt of the conventional wisdom about the highest things. The most cherished beliefs of the community, the collective hopes and fears, are centered on its gods. The unpardonable thing is to be beyond these hopes and fears, beyond the awe and shame the gods impose.

Countless attempts have been made to no avail to construct a continuity from the supreme principle of the intellectual world to the finite world. The oldest and most frequent of these attempts is well known: the principle of emanation, according to which the outflowings from the godhead, in gradual increments and detachment from the ordinary source, losing their divine perfection until, in the end, they pass into the opposite (matter, privation), just as light is finally confined by darkness.

O thou who art able to write a Book, which once in the two centuries or oftener there is a man gifted to do, envy not him whom they name City-builder, and inexpressibly pity him whom they name Conqueror or City-burner! Thou too art a Conqueror and Victor; but of the true sort, namely over the Devil: thou too hast built what will outlast all marble and metal, and be a wonder-bringing City of the Mind, a Temple and Seminary and Prophetic Mount, whereto all kindreds of the Earth will pilgrim.

Conflicting intellectual positions may actually come to supplement one another. It is imperative in the present transitional period to make use of the intellectual twilight which dominates our epoch and in which all values and points of view appear in their genuine relativity. We must realize once and for all that the meanings which make up our world are simply an historically determined and continuously developing structure in which man develops, and are in no sense absolute.

...the competition of the poor takes away from the reward of the rich.

When we consider the being and substance of that universe in which we are immutably set, we shall discover that neither we ourselves nor any substance doth suffer death; for nothing is in fact diminished in its substance, but all things, wandering through infinite space, undergo change of aspect.

What the Greeks sought, and what they obtained, was Equal Rights for all Citizens. In a certain sense, we might even say Equal Privileges, for there was no race favoured by the constitution more than another;-but there existed a great inequality of power, which indeed arose only by accident and not by the constitution of the State, but which nevertheless the State could not remedy;-and in so far there did not exist Equal Privileges.

Abstract terms (however useful they may be in argument) should be discarded in meditation, and the mind should be fixed on the particular and the concrete, that is, on the things themselves.
