Perception and knowledge could never be the same.

Evolution is definable as a change from an incoherent homogeneity to a coherent heterogeneity, accompanying the dissipation of motion and integration of matter.

I doubt not but one great reason why many children abandon themselves wholly to silly sports, and trifle away all their time insipidly, is, because they have found their curiosity baulk'd, and their inquiries neglected. But had they been treated with more kindness and respect, and their questions answered, as they should, to their satisfaction; I doubt not but that they would have taken more pleasure in learning, and improving their knowledge, wherein there would still be newness and variety, which is what they are delighted with, than in returning over and over to the same play and play-things.

Thus every action must be due to one or other of seven causes: chance, nature, compulsion, habit, reasoning, anger, or appetite.

There is probably no more abused a term in the history of philosophy than "representation," and my use of this term differs both from its use in traditional philosophy and from its use in contemporary cognitive psychology and artificial intelligence.... The sense of "representation" in question is meant to be entirely exhausted by the analogy with speech acts: the sense of "represent" in which a belief represents its conditions of satisfaction is the same sense in which a statement represents its conditions of satisfaction. To say that a belief is a representation is simply to say that it has a propositional content and a psychological mode.

The huge laugh is a most extreme expression of freedom.

Then are the children free. Notwithstanding, lest we should offend them, go thou to the sea, and cast an hook, and take up the fish that first cometh up; and when thou hast opened his mouth, thou shalt find a piece of money: that take, and give unto them for me and thee.

So-called professional mathematicians have, in their reliance on the relative incapacity of the rest of mankind, acquired for themselves a reputation for profundity very similar to the reputation for sanctity possessed by theologians.

The scientific attitude of mind involves a sweeping away of all other desires in the interests of the desire to know-it involves suppression of hopes and fears, loves and hates, and the whole subjective emotional life, until we become subdued to the material, able to see it frankly, without preconceptions, without bias, without any wish except to see it as it is, and without any belief that what it is must be determined by some relation, positive or negative, to what we should like it to be, or to what we can easily imagine it to be.

Of course, not everything old is beautiful, any more than everything black, or everything white, or everything young. But the notion that old means ugly is every bit as harmful as the prejudice that black is ugly. In one way it is even more pernicious. The notion that only what is new and young is beautiful poisons our relationship to the past and to our own future. It keeps us from understanding our roots and the greatest works of our culture and other cultures. It also makes us dread what lies ahead of us and leads many to shirk reality.

As soon as we have contrived to give our pupil an idea of the word "Useful," we have got an additional means of controlling him, for this word makes a great impression on him, provided that its meaning for him is a meaning relative to his own age, and provided he clearly sees its relation to his own well-being. This word makes no impression on your scholars because you have taken no pains to give it a meaning they can understand, and because other people always undertake to supply their needs so that they never require to think for themselves, and do not know what utility is. "What is the use of that?"

We must consider both the ultimate end and all clear sensory evidence, to which we refer our opinions; for otherwise everything will be full of uncertainty and confusion.

Fate and temperament are two words for one and the same concept.

With a greedy man thou shouldst not be a partner, and do not trust him with the leadership.

Virtuous men alone possess friends.

Nature made women mature early and had them demand gentle and polite treatment from men, so that they would find themselves imperceptibly fettered by a child due to their own magnanimity; and they would find themselves brought, if not quite to morality itself, then at least to that which cloaks it, moral behavior, which is the preparation and introduction to morality.

Love to his soul gave eyes; he knew things are not as they seem. The dream is his real life; the world around him is the dream.

If I seem happy to you . . . You could never say anything that would please me more. For men are made for happiness, and anyone who is completely happy has a right to say to himself, 'I am doing God's will on earth.' All the righteous, all the saints, all the holy martyrs were happy.

Fools -- for their thoughts are not well-considered who suppose that not-being exists or that anything dies and is wholly annihilated.

The mystical impulse in men is somehow a desire to possess the universe. In women, it's a desire to be possessed.

You rejoice in having made a convert to Atheism. I think there is something unnatural in a zeal of proselytism in an Atheist. I do not believe in an intellectual God, a God made after the image of man. In the vulgar acceptation of the word, therefore, I think a man is right who does not believe in God, but I am also persuaded that a man is wrong who is without religion.

A proposition is completely logically analyzed if its grammar is made completely clear: no matter what idiom it may be written or expressed in...

The revolutionaries say: "The government organization is bad in this and that respect; it must be destroyed and replaced by this and that." But a Christian says: "I know nothing about the governmental organization, or in how far it is good or bad, and for the same reason I do not want to support it."

There were honest people long before there were Christians and there are, God be praised, still honest people where there are no Christians. It could therefore easily be possible that people are Christians because true Christianity corresponds to what they would have been even if Christianity did not exist.

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

Indeed, it is tempting to suppose that it is self evident that things should be so arranged so as to lead to the most good.

The question is asked in ignorance, by one who does not even know what can have led him to ask it.

The philosophy of Bergson, which is a spiritualist restoration, essentially mystical, medieval, Quixotesque, has been called a demi-mondaine philosophy. Leave out the demi; call it mondaine, mundane. Mundane - yes, a philosophy for the world and not for philosophers, just as chemistry ought to be not for chemists alone. The world desires illusion (mundus vult decipi) - either the illusion antecedent to reason, which is poetry, or the illusion subsequent to reason, which is religion. And Machiavelli has said that whosoever wishes to delude will always find someone willing to be deluded. Blessed are they who are easily befooled!

A good indignation brings out all one's powers.

The supporters of the Development Hypothesis... can show that any existing species-animal or vegetable-when placed under conditions different from its previous ones, immediately begins to undergo certain changes fitting it for the new conditions. They can show that in successive generations these changes continue; until, ultimately, the new conditions become the natural ones. They can show that in cultivated plants, in domesticated animals, and in the several races of men, such alterations have taken place. They can show that the degrees of difference so produced are often, as in dogs, greater than those on which distinctions of species are in other cases founded.

Blair has been the modern man he claims to be: for him, a sense of subjective certainty is all that is needed for an action to be right. If deception is needed to realise the providential design, it cannot be truly deceitful.

Something that is merely negative creates nothing.

The patient typically finds himself impelled by some deep, inner conviction that something is true, or right, or virtuous: a conviction that doesn't seem to owe anything to evidence or reason, but which, nevertheless, he feels as totally compelling and convincing. We doctors refer to such a belief as "faith".

No sane person should believe that something is 'subjective' merely because it cannot be settled beyond controversy.

Language is a skin: I rub my language against the other. It is as if I had words instead of fingers, or fingers at the tip of my words. My language trembles with desire.

A creative economy is the fuel of magnificence.

You will have seen that my brother died suddenly in Marseilles. I inherit from him a title, but not a penny of money, as he was bankrupt. A title is a great nuisance to me, and I am at a loss what to do, but at any rate I do not wish it employed in connection with any of my literary work. There is, so far as I know, only one method of getting rid of it, which is to be attainted of high treason, and this would involve my head being cut off on Tower Hill. This method seems to me perhaps somewhat extreme...

Talk of mysteries! - Think of our life in nature, - daily to be shown matter, to come in contact with it, - rocks, trees, wind on our cheeks! The solid earth! the actual world! the common sense! Contact! Contact! Who are we? where are we?

Incredible that the prospect of having a biographer has made no one renounce having a life.

If thou intend to do any good; tarry not till to-morrow! for thou knowest not what may chance thee this night.

The origin of our passions, the root and spring of all the rest, the only one which is born with man, which never leaves him as long as he lives, is self-love; this passion is primitive, instinctive, it precedes all the rest, which are in a sense only modifications of it. In this sense, if you like, they are all natural. But most of these modifications are the result of external influences, without which they would never occur, and such modifications, far from being advantageous to us, are harmful. They change the original purpose and work against its end; then it is that man finds himself outside nature and at strife with himself.

In historical events great men - so-called - are but labels serving to give a name to the event, and like labels they have the least possible connection with the event itself. Every action of theirs, that seems to them an act of their own free will, is in an historical sense not free at all, but in bondage to the whole course of previous history, and predestined from all eternity.

'Tis well to restrain the wicked, and in any case not to join him in his wrong-doing.

Men remain in their present low and primitive condition; but if they should feel the influence of the spring of springs arousing them, they would of necessity rise to a higher and more ethereal life.

""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".

The sun provides the moon with its brightness.

I do not believe that I am now dreaming, but I cannot prove that I am not. I am, however, quite certain that I am having certain experiences, whether they be those of a dream or those of waking life.

Science is a systematic method for studying and working out those generalizations that seem to describe the behavior of the universe. It could exist as a purely intellectual game that would never affect the practical life of human beings either for good or evil, and that was very nearly the case in ancient Greece, for instance. Technology is the application of scientific findings to the tools of everyday life, and that application can be wise or unwise, useful or harmful. Very often, those who govern technological decisions are not scientists and know little about science.

Nothing is so fatiguing as the eternal hanging on of an uncompleted task.
