William James used to preach the "will-to-believe." For my part, I should wish to preach the "will-to-doubt." None of our beliefs are quite true; all at least have a penumbra of vagueness and error. What is wanted is not the will to believe, but the will to find out, which is the exact opposite.

A person who already displays ... cruelty to animals is also no less hardened towards men. We can already know the human heart, even in regard to animals.

Now the basic impulse behind existentialism is optimistic, very much like the impulse behind all science. Existentialism is romanticism, and romanticism is the feeling that man is not the mere he has always taken himself for. Romanticism began as a tremendous surge of optimism about the stature of man. Its aim - like that of science - was to raise man above the muddled feelings and impulses of his everyday humanity, and to make him a god-like observer of human existence.

The audience, as ground, shapes and controls the work of art.

The job of science will never be done, it will just sink deeper and deeper into never-ending complexity.

Elements of empirical language are manipulated in their rigidity, as if they were elements of a true and revealed language. The empirical usability of the sacred ceremonial words makes both the speaker and listener believe in their corporeal presence.

I can assure you that there is the greatest practical benefit in making a few failures early in life. You learn that which is of inestimable importance - that there are a great many people in the world who are just as clever as you are. You learn to put your trust, by and by, in an economy and frugality of the exercise of your powers, both moral and intellectual; and you very soon find out, if you have not found it out before, that patience and tenacity of purpose are worth more than twice their weight of cleverness.

Let a man once overcome his selfish terror at his own finitude, and his finitude is, in one sense, overcome.

Corruption of politics has nothing to do with the morals, or the laxity of morals, of various political personalities. Its cause is altogether a material one. Politics is the reflex of the business and industrial world, the mottos of which are: "To take is more blessed than to give"; "buy cheap and sell dear"; "one soiled hand washes the other." There is no hope even that woman, with her right to vote, will ever purify politics.

The essence of our God is obscure. It ripens continuously; perhaps victory is strenghened with our every valorous deed, but perhaps even all these agonizing struggles toward deliverance and victory are inferior to the nature of divinity. Whatever it might be, we fight on without certainty, and our virtue, uncertain of any rewards, acquires a profound nobility.

Most of the luxuries, and many of the so-called comforts of life, are not only not indispensable, but positive hindrances to the elevation of mankind.

At the core of all well-founded belief, lies belief that is unfounded.

Human beings are social animals. We were social before we were human.

The complexity of the connection between the world of perception and the world of physics does not preclude that such a connection can be shown to exist at any time.

From each according to his abilities, to each according to his needs.

Domination has its own aesthetics, and democratic domination has its democratic aesthetics.

When the mirror meets with an ugly woman, when a rare ink-stone finds a vulgar owner, and when a good sword is in the hands of a common general, there is utterly nothing to be done about it.

The people resemble a wild beast, which, naturally fierce and accustomed to live in the woods, has been brought up, as it were, in a prison and in servitude, and having by accident got its liberty, not being accustomed to search for its food, and not knowing where to conceal itself, easily becomes the prey of the first who seeks to incarcerate it again.

I accept nothing on authority. A hypothesis must be backed by reason, or else it is worthless.

As a way of maintaining relative intellectual independence, having the attitude of an amateur instead of a professional is a better course.

You wanted God's ideas about what was best for you to coincide with your ideas, but you also wanted him to be the almighty Creator of heaven and earth so that he could properly fulfill your wish. And yet, if he were to share your ideas, he would cease to be the almighty Father.

It seldom happens, however, that a great proprietor is a great improver.

Courtship is the time for sowing those seeds which will grow up ten years into domestic hatred.

Whatever limits us we call Fate.

If I compare arithmetic with a tree that unfolds upward into a multitude of techniques and theorems while its root drives into the depths, then it seems to me that the impetus of the root.

Philosophy is the self-correction by consciousness of its own initial excess of subjectivity. Each actual occasion contributes to the circumstances of its origin additional formative elements deepening its own peculiar individuality. Consciousness is only the last and greatest of such elements by which the selective character of the individual obscures the external totality from which it originates and which it embodies. An actual individual, of such higher grade, has truck with the totality of things by reason of its sheer actuality; but it has attained its individual depth of being by a selective emphasis limited to its own purposes. The task of philosophy is to recover the totality obscured by the selection.

The plea of anger or of drunkenness - as having placed the criminal for the moment beyond the control of his reason - relieves him from the charge of premeditated and malicious intent; but a rational legislation will rather provide more severe than milder punishment for such cases, particularly if such a state of mind is habitual with the accused; for a single unlawful act may well constitute an exception from an otherwise blameless life. But a person who pleads, "I habitually get so angry or so drunk as not to be any longer master of my senses!" confesses thereby that he changes himself into a beast on a fixed principle, and that he is, therefore, not fit to live among rational beings.

After Riemann had made known his discoveries, mathematicians busied themselves with working out his system of geometrical ideas formally; chief among these were Christoffel, Ricci, and Levi-Civita. Riemann... clearly left the real development of his ideas in the hands of some subsequent scientist whose genius as a physicist could rise to equal flights with his own as a mathematician. After a lapse of seventy years this mission has been fulfilled by Einstein.

Now, as to universal love and mutual aid, they are beneficial and easy beyond a doubt. It seems to me that the only trouble is that there is no superior who encourages it. If there is a superior who encourages it, promoting it with rewards and commendations, threatening its reverse with punishments, I feel people will tend toward universal love and mutual aid like fire tending upward and water downwards - it will be unpreventable in the world.

No man has ever been so far advanced by Fortune that she did not threaten him as greatly as she had previously indulged him.

No sacrifice is lost for a great ideal!

The consciousness of a general idea has a certain "unity of the ego" in it, which is identical when it passes from one mind to another. It is, therefore, quite analogous to a person, and indeed, a person is only a particular kind of general idea.

Mankind was never so happily inspired as when it made a cathedral.

The individual who is subordinate to an objective law feels himself determined by it, while he, in turn, in no way determines the law, and has no possibility of reacting to it in a manner which could influence it-quite in contrast to even the most miserable slave, who, in some fashion at last, can still in this sense react to his master.

Science has taught... me to be careful how I adopt a view which jumps with my preconceptions, and to require stronger evidence for such belief than for one to which I was previously hostile. My business is to teach my aspirations to conform themselves to fact, not to try and make facts harmonise with my aspirations.

Of all human and ancient opinions concerning religion, that seems to me the most likely and most excusable, that acknowledged God as an incomprehensible power, the original and preserver of all things, all goodness, all perfection, receiving and taking in good part the honour and reverence that man paid him, under what method, name, or ceremonies soever

I assert once again as a truth to which history as a whole bears witness that men may second their fortune, but cannot oppose it; that they may weave its warp, but cannot break it. Yet they should never give up, because there is always hope, though they know not the end and more towards it along roads which cross one another and as yet are unexplored; and since there is hope, they should not despair, no matter what fortune brings or in what travail they find themselves.

Feuerbach is saying: No, wait a minute - if you are going to be allowed to go on living as you are living, then you also have to admit that you are not Christians. Feuerbach has understood the requirements but cannot force himself to submit to them - ergo, he prefers to renounce being a Christian. And now, no matter how great a responsibility he must bear, he takes a position that is not unsound, that is, it is wrong of established Christendom to say that Feuerbach is attacking Christianity; it is not true, he is attacking the Christians by demonstrating that their lives do not correspond to the teachings of Christianity.

Popular escapist fiction enchants adult readers without challenging them to be educated for critical consciousness.

The lowest degree of education is to distinguish oneself from the ignorant ordinary man. The educated man does not loathe honey even if he finds it in the surgeon's cupping-glass; he realizes that the cupping glass does not essentially alter the honey. The natural aversion from it in such a case rests on popular ignorance, arising from the fact that the cupping-glass is made only for impure blood. Men imagine that the blood is impure because it is in the cupping-glass, and are not aware that the impurity is due to a property.

We look at the present through a rear-view mirror. We march backwards into the future.

A man of Intellect, of real and not sham Intellect, is by the nature of him likewise inevitably a man of nobleness, a man of courage, rectitude, pious strength; who, even because he is and has been loyal to the Laws of this Universe, is initiated into discernment of the same; to this hour a Missioned of Heaven; whom if men follow, it will be well with them; whom if men do not follow, it will not be well. Human Intellect, if you consider it well, is the exact summary of Human Worth; and the essence of all worth-ships and worships is reverence for that same.

All human knowledge begins with intuitions, proceeds from thence to concepts, and ends with ideas.

Why do ye also transgress the commandment of God by your tradition? For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death. But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me; And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition. Ye hypocrites, well did Esaias prophesy of you, saying, This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me. But in vain they do worship me, teaching for doctrines the commandments of men.
