A confession has to be part of your new life.

How can it be that mathematics, being, after all, a product of human thought which is independent of experience, is so admirably appropriate to the objects of reality? Is human reason, then, without experience, merely by taking thought, able to fathom the properties of real things?

It would be deeply depressing if the only way children could get moral values was from religion. Either from scripture, and God knows we don't want them to get it from scripture, I mean, just look at scripture. Or, from being afraid of God, being intimidated by God. Anybody who is good for only those two reasons is not really being good at all. Why not teach children things like the Golden Rule, do as you would be done by, how would you like it if other children did that to you, so why do you do it to them... I think it's depressing that anybody should suggest that you actually need God in order to be moral. I would hope that our morals come from a better source than that, and therefore they are genuinely moral rather than based on outmoded scripture, or based on fear.

Chance seldom interferes with the wise man; his greatest and highest interests have been, are, and will be, directed by reason throughout his whole life.

Frazer is much more savage than most of his savages, for they are not as far removed from the understanding of spiritual matter as a twentieth-century Englishman. His explanations of primitive practices are much cruder than the meaning of these practices themselves.

The young generations of the world, who had in them the freshness of young children, and yet the depth of earnest men, who did not think that they had finished off all things in Heaven and Earth by merely giving them scientific names, but had to gaze direct at them there, with awe and wonder: they felt better what of divinity is in man and Nature; they, without being mad, could worship Nature, and man more than anything else in Nature.

Necessity makes a joke of civilization.

Man's chief difference from the brutes lies in the exuberant excess of his subjective propensities - his preeminence over them simply and solely in the number and in the fantastic and unnecessary character of his wants, physical, moral, aesthetic, and intellectual. Had his whole life not been a quest for the superfluous, he would never have established himself as inexpugnably as he has done in the necessary.

I veil my face before thee, and lay my finger on my lips. What thou art in thyself, or how thou appearest to thyself, I can never know. After living through a thousand lives, I shall comprehend Thee as little as I do now in this mansion of clay. What I can comprehend, becomes finite by my mere comprehension, and this can never, by perpetual ascent, be transformed into the infinite, for it does not differ from it in degree merely, but in kind. By that ascent we may find a greater and greater man, but never a God, who is capable of no measurement.

At puberty, the elements of an unsuperstitious sexual morality ought to be taught. Boys and girls should be taught that nothing can justify sexual intercourse unless there is mutual inclination... Boys and girls should be taught respect for each other's liberty; they should be made to feel that nothing gives one human being rights over another, and that jealousy and possessiveness kill love. They should be taught that to bring another human being into the world is a very serious matter, only to be undertaken when the child will have a reasonable prospect of health, good surroundings, and parental care. But they should also be taught methods of birth control, so as to insure that children shall only come when they are wanted. Finally, they should be taught the dangers of venereal disease, and the methods of prevention and cure. The increase of human happiness to be expected from sex education on these lines is immeasurable.

Women crave for being loved, not for loving. They scream out at you for sympathy all day long, they are incapable of giving any in return, for they cannot remember your affairs long enough to do so... They cannot state a fact accurately to another, nor can that other attend to it accurately enough for it to become information. Now is not all this the result of want of sympathy?... I am sick with indignation at what wives and mothers will do of the most egregious selfishness. And people call it all maternal or conjugal affection, and think it pretty to say so. No, no, let each person tell the truth from their own experience.

There are men and gods, and beings like Pythagoras.

A man with two trades to his credit can easily learn another ten.

Tell them I've had a wonderful life.

Philosophy is not politics, and we do our best, within our all-too-human limitations, to seek the truth, not to score points against opponents. There is little satisfaction in gaining an easy triumph over a weak opponent while ignoring better arguments against your views. 

Let the eye of vigilance never be closed.

The 'Enlightenment', which discovered the liberties, also invented the disciplines.

Formerly, it was held by philosophers and mathematicians alike that the proofs in Geometry depended on the figure; nowadays, this is known to be false. In the best books there are no figures at all. The reasoning proceeds by the strict rules of formal logic from a set of axioms laid down to begin with.

We must fight those who are committed to destruction, without replicating their destructiveness. Understanding how to fight in this way is the task and the bind of a nonviolent ethics and politics.

I have no fear that the result of our experiment will be that men may be trusted to govern themselves without a master. Could the contrary of this be proved, I should conclude either that there is no god, or that he is a malevolent being.

Man's position in the world is defined by the fact that in every dimension of his being and behavior he finds himself at every moment between two boundaries. This condition appears as the formal structure of our existence, filled always with different contents in life's diverse provinces, activities, and destinies. We feel that the content and value of every hour stands between a higher and a lower; every thought between a wiser and a more foolish; every possession between a more extended and a more limited; every deed between a greater and a lesser measure of meaning, adequacy, and morality.

I consider you the most honest and truthful of men, more honest and truthful than anyone; and if they say that your mind...that is, that you're sometimes afflicted in your mind, it's unjust. I made up my mind about that, and disputed with others, because, though you really are mentally afflicted (you won't be angry with that, of course; I'm speaking from a higher point of view), yet the mind that matters is better in you than in any of them. It's something, in fact, they have never dreamed of. For there are two sorts of mind: one that matters, and one that doesn't matter.

First we have to believe, and then we believe.

In principle and in practice, in a right track and in a wrong one, the rarest of all human qualities is consistency.

I too have sworn heedlessly and all the time, I have had this most repulsive and death-dealing habit. I'm telling your graces; from the moment I began to serve God, and saw what evil there is in forswearing oneself, I grew very afraid indeed, and out of fear I applied the brakes to this old, old, habit.

All law relations are determined by this principle: each one must restrict his freedom by the possibility of the freedom of the other. ... My freedom is limited by the freedom of the other only on condition that he limits his freedom by the conception of mine. Otherwise he is lawless. Hence, if a law-relation is to result from my cognition of the other, the cognition and the consequent limitation of freedom must have been mutual. All law-relation between persons is, therefore, conditioned by their mutual cognition of each other, and is, at the same time, completely determined thereby.

Wrongly do the Greeks suppose that aught begins or ceases to be; for nothing comes into being or is destroyed; but all is an aggregation or secretion of pre-existent things: so that all-becoming might more correctly be called becoming-mixed, and all corruption, becoming-separate.

We ourselves are the entities to be analyzed.

All they that take the sword shall perish with the sword.

Historians of ideas, however scrupulous and minute they may feel it necessary to be, cannot avoid perceiving their material in terms of some kind of pattern.

Men have superior strength of body; but were it not for mistaken notions of beauty, women would acquire sufficient to enable them to earn their own subsistence, the true definitions of independence; and to bear those bodily inconveniences and exertions that are requisite to strengthen the mind. Let us then, by being allowed to take the same exercise as boys, not only during infancy, but youth, arrive at perfection of body, that we may know how far the nation superiority of man extends . For what reason or virtue can be expected from a creature when the seed-time of life is neglected? None; did not the winds of heaven casually scatter many useful seeds in fallow ground.

I do nothing, granted. But I see the hours pass - which is better than trying to fill them.

Do not all theists insist that there can be no morality, no justice, honesty or fidelity without the belief in a Divine Power? Based upon fear and hope, such morality has always been a vile product, imbued partly with self-righteousness, partly with hypocrisy. As to truth, justice, and fidelity, who have been their brave exponents and daring proclaimers? Nearly always the godless ones: the Atheists; they lived, fought, and died for them. They knew that justice, truth, and fidelity are not conditioned in heaven, but that they are related to and interwoven with the tremendous changes going on in the social and material life of the human race; not fixed and eternal, but fluctuating, even as life itself.

My immediate consciousness, my absolute perception, cannot go beyond myself, - I have immediate knowledge only of myself, whatever I know further I know only by reasoning, in the same manner in which I have come to those conclusions concerning the original powers of Nature, which certainly do not lie within the circle of my perceptions. I, however, - that which I call myself, - am not the man-forming power of Nature, but only one of its manifestations ; and only of this manifestation am I conscious, not of that power, whose existence I have only discovered from the necessity of explaining my own.

O saving Victim, opening wideThe gate of heaven to man below,Our foes press on from every side,Thine aid supply, Thy strength bestow.

Even pacifist agitation or the nation-wide fever of big sports competitions acts as a spur to war fever in circumstances like ours. Any kind of excitement or emotion contributes to the possibility of dangerous explosions when the feelings of huge populations are kept inflamed even in peacetime for the sake of the advancement of commerce. Headlines mean street sales. It takes emotion to move merchandise. And wars and rumors of wars are the merchandise and also the emotion of the popular press.

We are all made for mutual assistance, as the feet, the hands, and the eyelids, as the rows of the upper and under teeth, from whence it follows that clashing and opposition is perfectly unnatural.

The governors of the world believe, and have always believed, that virtue can only be taught by teaching falsehood, and that any man who knew the truth would be wicked. I disbelieve this, absolutely and entirely. I believe that love of truth is the basis of all real virtue, and that virtues based upon lies can only do harm.

To speak ill of others is a dishonest way of praising ourselves; let us be above such transparent egotism. If you can't say good and encouraging things, say nothing. Nothing is often a good thing to do, and always a clever thing to say.

When a reasonable Soul forsaketh his divine nature, and becometh beast-like, it dieth. For though the substance of the Soul be incorruptible: yet, lacking the use of Reason, it is reputed dead; for it loseth the Intellective Life.

The death of dogma is the birth of morality.

One has to do something new in order to see something new.

What is not heartrending is superfluous, at least in music.

As the State formerly played a most important part in the revolutions that abolished the old economic systems, so it must again be the State that should abolish capitalism.

Marriage as a community of interests unfailingly means the degradation of the interested parties, and it is the perfidy of the world's arrangements that no one, even if aware of it, can escape such degradation. The idea might therefore be entertained that marriage without ignominy is a possibility reserved for those spared the pursuit of interests, for the rich. But the possibility is purely formal, for the privileged are precisely those in whom the pursuit of interests has become second-nature-they would not otherwise uphold privilege.

No freeman shall be debarred the use of arms within his own lands.

I respect orders but I respect myself too and I do not obey foolish rules made especially to humiliate me.

... happiness is not an ideal of reason, but of imagination, resting on merely empirical grounds…

Not being able to govern events, I govern myself.
