Man cannot be free if he does not know that he is subject to necessity, because his freedom is always won in his never wholly successful attempts to liberate himself from necessity.

Volumes might be written upon the impiety of the pious.

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

When I was 15 years old, or 16, I carried around on the streets of Brooklyn a paperback copy of Plato's Republic, front cover facing outward. I had read only some of it and understood less, but I was excited by it and knew it was something wonderful.

If you don't know how to die, don't worry; Nature will tell you what to do on the spot, fully and adequately. She will do this job perfectly for you; don't bother your head about it.

I take it for granted, when I am invited to lecture anywhere, - for I have had a little experience in that business, - that there is a desire to hear what I think on some subject, though I may be the greatest fool in the country, - and not that I should say pleasant things merely, or such as the audience will assent to; and I resolve, accordingly, that I will give them a strong dose of myself. They have sent for me, and engaged to pay for me, and I am determined that they shall have me, though I bore them beyond all precedent.

There is no formula for generating the authentic warmth of love. It cannot be copied. You cannot talk yourself into it or rouse it by straining at the emotions or by dedicating yourself solemnly to the service of mankind. Everyone has love, but it can only come out when he is convinced of the impossibility and the frustration of trying to love himself. This conviction will not come through condemnations, through hating oneself, through calling self love bad names in the universe. It comes only in the awareness that one has no self to love.

The least initial deviation from the truth is multiplied later a thousandfold.

The writers by whom, more than by any others, a new mode of political thinking was brought home to me, were those of the St. Simonian school in France. In 1829 and 1830 I became acquainted with some of their writings. They were then only in the earlier stages of their speculations. They had not yet dressed out their philosophy as a religion, nor had they organized their scheme of Socialism. They were just beginning to question the principle of hereditary property. I was by no means prepared to go with them even this length; but I was greatly struck with the connected view which they for the first time presented to me, of the natural order of human progress; and especially with their division of all history into organic periods and critical periods.

The confession of evil works is the first beginning of good works.

Now in all of us, however constituted, but to a degree the greater in proportion as we are intense and sensitive and subject to diversified temptations, and to the greatest possible degree if we are decidedly psychopathic, does the normal evolution of character chiefly consist in the straightening out and unifying of the inner self. The higher and the lower feelings, the useful and the erring impulses, begin by being a comparative chaos within us - they must end by forming a stable system of functions in right subordination. Unhappiness is apt to characterize the period of order-making and struggle.

A solitary man is a God, or a beast.

I conceive that the description so often given of a Benthamite, as a mere reasoning machine, though extremely inapplicable to most of those who have been designated by that title, was during two or three years of my life not altogether untrue of me. ...There is nothing very extraordinary in this fact: no youth of the age I then was, can be expected to be more than one thing, and this was the thing I happened to be. Ambition and desire of distinction, I had in abundance; and zeal for what I thought the good of mankind was my strongest sentiment, mixing with and colouring all others. But my zeal was as yet little else, at that period of my life, than zeal for speculative opinions. It had not its root in genuine benevolence, or sympathy with mankind; though these qualities held their due place in my ethical standard. Nor was it connected with any high enthusiasm for ideal nobleness.

For as only one thing is necessary, and as the theme of the talk is the willing of only one thing: hence the consciousness before God of one's eternal responsibility to be an individual is that one thing necessary.

He will better comprehend the foundations and measures of decency and justice, and have livelier, and more lasting impressions of what he ought to do, by giving his opinion on cases propos'd, and reasoning with his tutor on fit instances, than by giving a silent, negligent, sleepy audience to his tutor's lectures; and much more than by captious logical disputes, or set declamations of his own, upon any question. The one sets the thoughts upon wit and false colours, and not upon truth; the other teaches fallacy, wrangling, and opiniatry; and they are both of them things that spoil the judgment, and put a man out of the way of right and fair reasoning; and therefore carefully to be avoided by one who would improve himself, and be acceptable to others.

The attempt to separate everything from everything else is not only not in good taste but also shows that a man is utterly uncultivated and unphilosophical. The complete separation of each thing from all is the utterly final obliteration of all discourse. For our power of discourse is derived from the interweaving of the classes or ideas with one another.

Man know thyself; then thou shalt know the Universe and God.

Nature is no sentimentalist, - does not cosset or pamper us. We must see that the world is rough and surly, and will not mind drowning a man or a woman, but swallows your ships like a grain of dust. The cold, inconsiderate of persons, tingles your blood, benumbs your feet, freezes a man like an apple. The diseases, the elements, fortune, gravity, lightning, respect no persons.

A state of war only serves as an excuse for domestic tyranny.

If what the philosophers say be true,—that all men's actions proceed from one source; that as they assent from a persuasion that a thing is so, and dissent from a persuasion that it is not, and suspend their judgment from a persuasion that it is uncertain, so likewise they seek a thing from a persuasion that it is for their advantage.

What the inventive genius of mankind has bestowed upon us in the last hundred years could have made human life care free and happy if the development of the organizing power of man had been able to keep step with his technical advances. As it is, the hardly bought achievements of the machine age in the hands of our generation are as dangerous as a razor in the hands of a three-year-old child. The possession of wonderful means of production has not brought freedom-only care and hunger.

Great men, great nations, have not been boasters and buffoons, but perceivers of the terror of life, and have manned themselves to face it.

We are alive within mystery, by miracle. "Life," wrote Erwin Chargaff, "is the continual intervention of the inexplicable." We have more than we can know. We know more than we can say. The constructions of language (which is to say the constructions of thought) are formed within experience, not the other way around. Finally we live beyond words, as also we live beyond computation and beyond theory. There is no reason whatever to assume that the languages of science are less limited than other languages.

... 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.

Men can be provincial in time, as well as in place.

When the basic structure of society is publicly known to satisfy its principles for an extended period of time, those subject to these arrangements tend to develop a desire to act in accordance with these principles and to do their part in institutions which exemplify them.

These two states which it is necessary to know together in order to see the whole truth, being known separately, lead necessarily to one of these two vices, pride or indolence, in which all men are invariably led before grace, since if they do not remain in their disorders through laxity, they forsake them through vanity, so true is that which you have just repeated to me from St. Augustine, and which I find to a great extent; for in fact homage is rendered to them in many ways.

""You do not love the mind of your race, nor the body. Any kind of creature will please you if only it is begotten by your kind as they now are. It seems to me, Thick One, what you really love is no completed creature but the very seed itself: for that is all that is left".

There can be no higher law in journalism than to tell the truth and shame the devil.

Do not act as if thou wert going to live ten thousand years. Death hangs over thee. While thou livest, while it is in thy power, be good.

One does not decide the truth of a thought according to whether it is right-wing or left-wing.

When a person is haughty, he distances himself from other people and thereby deprives himself of one of life's biggest pleasures-open, joyful communication with everyone.

I shall in no time forget that moment. We felt as if we had had in our souls a clear passing glimpse into this wondrous World.

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.

None of the things they learn, should ever be made a burthen to them, or impos's on them as a task. Whatever is so proposed, presently becomes irksome; the mind takes an aversion to it, though before it were a thing of delight or indifferency. Let a child but be ordered to whip his top at a certain time every day, whether he has or has not a mind to it; let this be but requir'd of him as a duty, wherein he must spend so many hours morning and afternoon, and see whether he will not soon be weary of any play at this rate. Is it not so with grown men?

If there is anything in the world that can really be called a man's property, it is surely that which is the result of his mental activity.

Every being ought to do that which is according to its constitution; and all other things have been constituted for the sake of the superior, but the rational for the sake of one another.

What is marvelous is that each day brings us a new reason to disappear.

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

The secret thoughts of a man run over all things, holy, prophane, clean, obscene, grave, and light, without shame, or blame...

Blessed are the poor in spirit, for theirs is the kingdom of heaven. Blessed are those who mourn, for they will be comforted. Blessed are the meek, for they will inherit the earth. Blessed are those who hunger and thirst for righteousness, for they will be filled. Blessed are the merciful, for they will be shown mercy. Blessed are the pure in heart, for they will see God. Blessed are the peacemakers, for they will be called sons of God. Blessed are those who are persecuted because of righteousness, for theirs is the kingdom of heaven. Blessed are you when people insult you, persecute you and falsely say all kinds of evil against you because of me. Rejoice and be glad, because great is your reward in heaven, for in the same way they persecuted the prophets who were before you.

There are two kinds of means. One kind is external to that which is accomplished; the other kind is taken up into the consequences and remains immanent in them. There are ends which are merely welcome cessations and there are ends that are fulfillments of what went before. The toil of the laborer is too often an antecedent to the wage he receives, as consumption of gasoline is merely a means to transportation. The means cease to act when the "end" is reached; one would be glad, as a rule, to get the result without having to employ the means. They are but the scaffolding.

Time is a game played beautifully by children.

Whatever the virtue may be, from whatever source it may come, it is worthy of esteem... Mind, beauty, wealth, nobility, although the children of chance, all have their own value, as skill, learning and virtue have theirs.

If a single cell, under appropriate conditions, becomes a man in the space of a few years, there can surely be no difficulty in understanding how, under appropriate conditions, a cell may, in the course of untold millions of years, give origin to the human race.

He that defers his charity 'till he is dead, is (if a man weighs it rightly) rather liberal of another man's, than of his own.
