Science is not a system of certain, or well established, statements; nor is it a statement which steadily advances towards state of finality. Our science is not knowledge (epistēmē): it can newer claim to have attained truth, or even substitute for it, such as probability. . . . We do not know; we can only guess.

Art thou angry with him whose arm-pits stink? art thou angry with him whose mouth smells foul? What good will this anger do thee?

To be shaken out of the ruts of ordinary perception, to be shown for a few timeless hours the outer and inner world, not as they appear to an animal obsessed with survival or to a human being obsessed with words and notions, but as they are apprehended, directly and unconditionally, by Mind at Large - this is an experience of inestimable value to everyone and especially to the intellectual.

How does the poet speak to men with power, but by being still more a man than they?

People talk sometimes of a bestial cruelty, but that's a great injustice and insult to the beasts; a beast can never be so cruel as a man, so artistically cruel. The tiger only tears and gnaws, that's all he can do. He would never think of nailing people by the ears, even if he were able to do it.

Thinking men and women the world over are beginning to realize that patriotism is too narrow and limited a conception to meet the necessities of our time.

Animals only follow their natural instincts; but man, unless he has experienced the influence of learning and philosophy, is at the mercy of impulses that are worse than those of a wild beast. There is no beast more savage and dangerous than a human being who is swept along by the passions of ambition, greed, anger, envy, extravagance, and sensuality.

If I have exhausted the justifications, I have reached bedrock and my spade is turned. Then I am inclined to say: "This is simply what I do."

In a liberal society you're not going to agree on the deepest... moral frameworks, but you are going to agree on factual information, and... if you can't agree on factual information it's very hard to deliberate in common... on what needs to be done in the future, and that's the situation we now face.

To-day, there are too many points of view of equal value and prestige, each showing the relativity of the other, to permit us to take any one position and to regard it as impregnable and absolute. Only this socially disorganized intellectual situation makes possible the insight, hidden until now by a generally stable social structure and the practicability of certain traditional norms, that every point of view is particular to a social situation.

A man should build a house with his own hands before he calls himself an engineer.

All the living hold together, and all yield to the same tremendous push. The animal takes its stand on the plant, man bestrides animality, and the whole of humanity, in space and in time, is one immense army galloping beside and before and behind each of us in an overwhelming charge able to beat down every resistance and clear the most formidable obstacles, perhaps even death.

What a pity and what a poverty of spirit, to assert that beasts are machines deprived of knowledge and sentiment, which affect all their operations in the same manner, which learn nothing, never improve, &c. Some barbarians seize this dog, who so prodigiously excels man in friendship, they nail him to a table, and dissect him living, to show the mezarian veins. You discover in him all the same organs of sentiment which are in yourself. Answer me, machinist, has nature arranged all the springs of sentiment in this animal that he should not feel? Has he nerves to be incapable of suffering? Do not suppose this impertinent contradiction in nature. The animal has received those of sentiment, memory, and a certain number of ideas. Who has bestowed these gifts, who has given these faculties? He who has made the herb of the field to grow, and who makes the earth gravitate towards the sun.

I believe that whatever we do or live for has its causality; it is good, however, that we cannot see through to it.

It is not by prayer and humility that you cause things to go as you wish, but by acquiring a knowledge of natural laws.

It is easy to follow in the sacred writings of the Jewish people the development of the religion of fear into the moral religion, which is carried further in the New Testament. The religions of all civilized peoples, especially those of the Orient, are principally moral religions. An important advance in the life of a people is the transformation of the religion of fear into the moral religion. But one must avoid the prejudice that regards the religions of primitive peoples as pure fear religions and those of the civilized races as pure moral religions. All are mixed forms, though the moral element predominates in the higher levels of social life.

In the "fulfillment" of both the laws and duty, ... the moral disposition ceases to be the universal, opposed to inclination, and inclination ceases to be particular, opposed to the law.

Every presentation of philosophy, whether oral or written, is to be taken and can only be taken in the sense of a means. Every system is only an expression or image of reason, and hence only an object of reason, an object which reason-a living power that procreates itself in new thinking beings-distinguishes from itself and posits as an object of criticism. Every system that is not recognized and appropriated as just a means, limits and warps the mind for it sets up the indirect and formal thought in the place of the direct, original and material thought.

For thus it is, men of Athens, in truth: wherever a man has placed himself thinking it is the best place for him, or has been placed by a commander, there in my opinion he ought to stay and to abide the hazard, taking nothing into the reckoning, either death or anything else, before the baseness of deserting his post.

Once when Phocion had delivered an opinion which pleased the people,... he turned to his friend and said, "Have I not unawares spoken some mischievous thing or other?"

War is the father and king of all: some he has made gods, and some men; some slaves and some free.

A modest man is steady, an humble man timid, and a vain one presumptuous.

Like a plague, the mad spirit is sweeping the country, infesting the clearest heads and staunchest hearts with the deathly germ of militarism.

The critical ontology of ourselves has to be considered not, certainly, as a theory, a doctrine, nor even as a permanent body of knowledge that is accumulating; it has to be conceived as an attitude, an ethos, a philosophical life in which the critique of what we are is at one and the same time the historical analysis of the limits that are imposed on us and an experiment with the possibility of going beyond them.

For my part, while I am as convinced a Socialist as the most ardent Marxian, I do not regard Socialism as a gospel of proletarian revenge, nor even, primarily, as a means of securing economic justice. I regard it primarily as an adjustment to machine production demanded by considerations of common sense, and calculated to increase the happiness, not only of proletarians, but of all except a tiny minority of the human race.

Dispersed as the Jews are, they still form one nation, foreign to the land they live in.

The law of gravity thus asserts itself when a house falls about our ears.

Human nature is not a machine to be built after a model, and set to do exactly the work prescribed for it, but a tree, which requires to grow and develop itself on all sides, according to the tendency of the inward forces which make it a living thing.

I hate Communism because it is the negation of liberty and because humanity is for me unthinkable without liberty. I am not a Communist, because Communism concentrates and swallows up in itself for the benefit of the State all the forces of society, because it inevitably leads to the concentration of property in the hands of the State, whereas I want the abolition of the State, the final eradication of the principle of authority and the patronage proper to the State, which under the pretext of moralizing and civilizing men has hitherto only enslaved, persecuted, exploited and corrupted them. I want to see society and collective or social property organized from below upwards, by way of free association, not from above downwards, by means of any kind of authority whatsoever.

Everyone has a religion, whether admitted or not, because it is impossible to be human without having some basic assumptions (or intuitions) about existence and the good life.

A good symbol is the best argument and is a missionary to persuade thousands.

But the thing a man does practically believe (and this is often enough without asserting it even to himself, much less to others); the thing a man does practically lay to heart, and know for certain, concerning his vital relations to this mysterious Universe, and his duty and destiny there, that is in all cases the primary thing for him, and creatively determines all the rest. That is his religion; or, it may be, his mere scepticism and no-religion: the manner it is in which he feels himself to be spiritually related to the Unseen World or No-World; and I say, if you tell me what that is, you tell me to a very great extent what the man is, what the kind of things he will do is.

We boil at different degrees.

"Since we cannot change reality, let us change the eyes which see reality," says one of my favorite Byzantine mystics. I did this when a child; I do it now as well in the most creative moments of my life.

When at the beginning of the so-called modern age, at the Renaissance, the pagan sense of religion came to life again, it took the concrete form in the knightly ideal with its codes of conduct of love and honor. But it was a paganism Christianized, baptized. "Woman - la donna - was the divinity enshrined within those savage breasts. Whosoever will investigate the memorials of primitive times will find this ideal of woman in its full force and purity; the Universe is woman.

The direction of society has been taken over by a type of man who is not interested in the principles of civilisation. Not of this or that civilisation but - from what we can judge to-day - of any civilisation. ...The type of man dominant to-day is a primitive one, a Naturmensch rising up in the midst of a civilised world.

A race preserves its vigour so long as it harbours a real contrast between what has been and what may be, and so long as it is nerved by the vigour to adventure beyond the safeties of the past. Without adventure, civilization is in full decay.

The salvation of reality is its obstinate, irreducible, matter-of-fact entities, which are limited to be no other than themselves. Neither science, nor art, nor creative action can tear itself away from obstinate, irreducible, limited facts.

The place of the father in the modern suburban family is a very small one - particularly if he plays golf, which he usually does.

The goal of maximizing the welfare of all may be better achieved by an ethic that accepts our inclinations and harnesses them so that, taken as a whole, the system works to everyone's advantage.

Lucidity's task: to attain a correct despair, an Olympian ferocity.

What is objective must be common to many minds and consequently transmissible from one to the other, and as this transmission can only come about by... discourse... we are even forced to conclude: no discourse no objectivity.

All men are liable to error; and most men are, in many points, by passion or interest, under temptation to it.

People are deeply imbedded in philosophical, i.e., grammatical confusions. And to free them presupposes pulling them out of the immensely manifold connections they are caught up in.

Upper middle-class upbringing has rooted out any element of what might appear to be self-assertion or egoism; good manners is to be like everyone else. So the male of the species becomes accustomed to suppress any stirring of impatience or originality. Shaw once said you can't learn to skate without making a fool of yourself; the British middle-class attitude seems to be that, in that case, you hadn't better skate at all. The result seems to be considerably more oppressive than being brought up in a Jewish ghetto or a west side slum.

The method of scientific investigation is nothing but the expression of the necessary mode of working of the human mind.
