Philosophy and religion are enemies, and because they are enemies they have need of one another. There is no religion without some philosophical basis, no philosophy without roots in religion. ... the attacks which are directed against religion from a presumed scientific or philosophical point of view are merely attacks from another but opposing religious point of view.

The harvest truly is plenteous, but the labourers are few; Pray ye therefore the Lord of the harvest, that he will send forth labourers into his harvest.

I never will, by any word or act, bow to the shrine of intolerance, or admit a right of inquiry into the religious opinions of others.

And having said this, Jesus smote his face with both his hands, and then smote the ground with his head. And having raised his head, he said: "Cursed be every one who shall insert into my sayings that I am the son of God." At these words the disciples fell down as dead, whereupon Jesus lifted them up, saying: 'Let us fear God now, if we would not be affrighted in that day.'

Your questions refer to words; so I have to talk about words. You say: The point isn't the word, but its meaning, and you think of the meaning as a thing of the same kind as the word, though also different from the word. Here the word, there the meaning.

The gods sell anything to everybody at a fair price.

Without the presence of black people in America, European-Americans would not be "white"-- they would be Irish, Italians, Poles, Welsh, and other engaged in class, ethnic, and gender struggles over resources and identity.

Sound knowledge respecting the habits and mode of life of the man-like Apes has been even more difficult of attainment than correct information regarding their structure.

An agreeable companion on a journey is as good as a carriage.

After the battle in Pharsalia, when Pompey was fled, one Nonius said they had seven eagles left still, and advised to try what they would do. "Your advice," said Cicero, "were good if we were to fight jackdaws."

In the new order a Locke was free-with almost no danger of being interfered with-to think his sublime thoughts, to seek the first causes of all things, to understand the nature of things. He could talk with his friends and teach the young. And there was money enough. The academies and universities satisfied Socrates' demand to be fed in the prytaneum.

Your god is too small.

I can't be sure God does not exist... On a scale of seven, where one means I know he exists, and seven I know he doesn't, I call myself a six... That doesn't mean I'm absolutely confident, that I absolutely know, because I don't.

Mere imagination would indeed be mere trifling; only no imagination is mere.

In France at least, the history of science and thought gives pride of place sciences, sciences of the necessary, all close to philosophy: one can observe in their history the almost uninterrupted emergence of truth and pure reason. The other disciplines, however - those, for example, that concern living beings, languages, or economic facts - are considered too tinged with empirical thought, too exposed to the vagaries of chance or imagery to age old traditions and external events, for it to be supposed that their history could be anything other irregular. At most, they are expected to provide evidence of a state of mind, an intellectual fashion, a mixture of archaism and bold conjecture, of intuition and blindness. But what if empirical knowledge, at a given time and in a given culture, did possess a well defined regularity.

The solution is, that we do not see the image on the retina at all, we only see by means of it.

Nothing prints more lively in our minds than something we wish to forget.

But capitalist production begets,with the inexorability of a law of Nature,its own negation. It is the negation of negation.

I joke sometimes to the effect that when I approach a part of a book where I must explain something I don't understand, I just type faster and faster and faster. Then, when I get to the part I don't understand, sheer inertia pushes me through. That's not literally true, of course, but there's something to it psychologically.

We now come to a decisive step of mathematical abstraction: we forget about what the symbols stand for... [The mathematician] need not be idle; there are many operations which he may carry out with these symbols, without ever having to look at the things they stand for.

In order to be transmuted into knowledge, every perception is and must be ordered and organized into categories. The extent, however, to which we can organize and express our experience in such conceptual forms is, in turn, dependent upon the frames of reference which happen to be available at a given historical moment. The concepts which we have and the universe of discourse in which we move, together with the directions in which they tend to elaborate themselves, are dependent largely upon the historical-social situation of the intellectually active and responsible members of the group.

'No one but you and one 'jade' I have fallen in love with, to my ruin. But being in love doesn't mean loving. You may be in love with a woman and yet hate her.

What can be said can and should always be said more and more simply and clearly.

What I hold fast to is not one proposition but a nest of propositions.

We must not attach knowledge to the mind, we have to incorporate it there.

Inequalities are permissible when they maximize, or at least all contribute to, the long term expectations of the least fortunate group in society.

Anything can be made to look good or bad by being redescribed.

If a false thought is so much as expressed boldly and clearly, a great deal has already been gained.

Therefore, on hearing His words let no one say either: "These are not Christ's words," or "These are not my words." On the contrary, if he knows that he is in the body of Christ, let him say: "These are both Christ's words and my words." Say nothing without Him, and He will say nothing without thee. We must not consider ourselves as strangers to Christ, or look upon ourselves as other than Himself.

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.

The pursuit of philosophy is founded on the belief that knowledge is good, even if what is known is painful. A man imbued with the philosophic spirit, whether a professional philosopher or not, will wish his beliefs to be as true as he can make them, and will, in equal measure, love to know and hate to be in error. This principle has a wider scope than may be apparent at first sight.

Suppose a surface to be part red and part blue; so that every point on it is either red or blue, and of course, no part can be both red and blue. What then, is the color of the surface in the immediate neighborhood of the point. ...it follows that the boundary is half red and half blue. In like manner, we find it necessary to hold that consciousness essentially occupies time... Thus, the present is half past and half time to come. ...Take another case: the velocity of a particle at any instant of time is its mean velocity during an infinitesimal instant in which that time is consumed. Just so, my immediate feeling is my feeling through an infinitesimal duration containing the present instant.

Young man! Deny yourself satisfaction (of amusement, of debauchery, of love, etc.), not with the Stoical intention of complete abstinence, but with the refined Epicurean intention of having in view an ever-growing pleasure. This stinginess with the cash of your vital urge makes you definitely richer through the postponement of pleasure, even if you should, for the most part, renounce the indulgence of it until the end of your life. The awareness of having pleasure under your control is, like everything idealistic, more fruitful and more abundant than everything that satisfies the sense through indulgence because it is thereby simultaneously consumed and consequently lost from the aggregate of totality.

I don't believe you until you tell me, do you really believe, for example, if they say they are Catholic, "Do you really believe that when a priest blesses a wafer, it turns into the body of Christ? Are you seriously telling me you believe that? Are you seriously saying that wine turns into blood?" Mock them. Ridicule them. In public. Don't fall for the convention that we're all too polite to talk about religion. Religion is not off the table. Religion is not off limits. Religion makes specific claims about the universe which need to be substantiated and need to be challenged and, if necessary, need to be ridiculed with contempt.

Poems are magic ceremonies of language.

The ordinary logic has a great deal to say about genera and species, or in our nineteeth century dialect, about classes. Now a class is a set of objects comprising all that stand to one another in a special relation of similarity. But where ordinary logic talks of classes the logic of relatives talks of systems. A system is a set of objects comprising all that stands to one another in a group of connected relations. Induction according to ordinary logic rises from the contemplation of a sample of a class to that of a whole class; but according to the logic of relatives it rises from the comtemplation of a fragment of a system to the envisagement of the complete system.

"The physical world is real." That is supposed to be the fundamental hypothesis. What does "hypothesis" mean here? For me, a hypothesis is a statement, whose truth must be assumed for the moment, but whose meaning must be raised above all ambiguity. The above statement appears to me, however, to be, in itself, meaningless, as if one said: "The physical world is cock-a-doodle-do." It appears to me that the "real" is an intrinsically empty, meaningless category (pigeon hole), whose monstrous importance lies only in the fact that I can do certain things in it and not certain others.

Doing what is for the good of the people, this must be the truest criterion of right government, in accordance with which the wise and good man will govern the affairs of his subjects. Just as the captain of a ship keeps watch for what is at any moment for the good of the vessel and the sailors, not by writing rules, but by making his science his law, and thus preserves his fellow voyagers, so may not a right government be established in the same way by men who could rule by this principle, making science more powerful than the laws? And whatever the wise rulers do, they can commit no error, so long as they maintain one great principle and by always dispensing absolute justice to them with wisdom and science are able to preserve the citizens and make them better than they were, so far as that is possible.

Diversity makes critical argument fruitful. ...[P]artners in an argument must share ...the wish to know, and the readiness to learn from the other ...by severely criticizing his views... and hearing... [the] reply. ...the so-called method of science consists in this kind of criticism.

Tell your master that if there were as many devils at Worms as tiles on its roofs, I would enter.

Under a government which imprisons any unjustly, the true place for a just man is also a prison... the only house in a slave State in which a free man can abide with honor.

In the deepest heart of all of us there is a corner in which the ultimate mystery of things works sadly.

In vain I sought relief from my favourite books; those memorials of past nobleness and greatness from which I had always hitherto drawn strength and animation. I read them now without feeling, or with the accustomed feeling minus all its charm; and I became persuaded, that my love of mankind, and of excellence for its own sake, had worn itself out. I sought no comfort by speaking to others of what I felt. If I had loved any one sufficiently to make confiding my griefs a necessity, I should not have been in the condition.

Would you know what makes men greedy for the future? It is because no one has yet found himself.

In doing good, we are generally cold, and languid, and sluggish; and of all things afraid of being too much in the right. But the works of malice and injustice are quite in another style. They are finished with a bold, masterly hand; touched as they are with the spirit of those vehement passions that call forth all our energies, whenever we oppress and persecute.

May not this religious reticence, in these devout good souls, be perhaps a merit, and sign of health in them? Jocelin, Eadmer, and such religious men, have as yet nothing of 'Methodism;' no Doubt or even root of Doubt. Religion is not a diseased self-introspection, an agonising inquiry: their duties are clear to them, the way of supreme good plain, indisputable, and they are traveling on it. Religion lies over them like an all-embracing heavenly canopy, like an atmosphere and life-element, which is not spoken of, which in all things is presupposed without speech. Is not serene or complete Religion the highest aspect of human nature.

To say that everything is idea or that everything is spirit, is the same as saying that everything is matter or that everything is energy, for if everything is idea or spirit, just as my consciousness is, it is not plain why the diamond should not endure for ever, if my consciousness, because it is idea or spirit, endures forever.
