All those to whom I looked up, were of opinion that the pleasure of sympathy with human beings, and the feelings which made the good of others, and especially of mankind on a large scale, the object of existence, were the greatest and surest sources of happiness. Of the truth of this I was convinced, but to know that a feeling would make me happy if I had it, did not give me the feeling.

I can prove now, for instance, that two human hands exist. How? By holding up my two hands, and saying, as I make a certain gesture with the right hand, "Here is one hand," and adding, as I make a certain gesture with the left, "and here is another." And if, by doing this, I have proved ipso facto the existence of external things, you will all see that I can also do it now in numbers of other ways: there is no need to multiply examples.

I have lived in the pursuit of a vision, both personal and social. Personal: to care for what is noble, for what is beautiful, for what is gentle; to allow moments of insight to give wisdom at more mundane times. Social: to see in imagination the society that is to be created, where individuals grow freely, and where hate and greed and envy die because there is nothing to nourish them. These things I believe, and the world, for all its horrors, has left me unshaken.

Attention consists of suspending our thought, leaving it detached, empty, and ready to be penetrated by the object; it means holding in our minds, within reach of this thought, but on a lower level and not in contact with it, the diverse knowledge we have acquired which we are forced to make use of.

The problem of induction is, roughly speaking, the problem of finding a way to prove that certain empirical generalizations which are derived from past experience will hold good also in the future. There are only two ways of approaching this problem on the assumption that it is a genuine problem, and it is easy to see that neither of them can lead to its solution.

Do not judge according to appearance, but judge with righteous judgment.

Each individual imagines that he can exist, live, think, and act for himself, and believes that he himself is the thinking principle of his thoughts; whereas in truth he is but a single ray of the ONE universal and necessary Thought.

Do not despair: one thief was saved. Do not presume: one thief was damned.

A religious creed differs from a scientific theory in claiming to embody eternal and absolutely certain truth, whereas science is always tentative, expecting that modification in its present theories will sooner or later be found necessary, and aware that its method is one which is logically incapable of arriving at a complete and final demonstration.

There is no alleviation for the sufferings of mankind except veracity of thought and of action, and the resolute facing of the world as it is, when the garment of make-believe, by which pious hands have hidden its uglier features, is stripped off.

One can say that the author is an ideological product, since we represent him as the opposite of his historically real function. (When a historically given function is represented in a figure that inverts it, one has an ideological production.) The author is therefore the ideological figure by which one marks the manner in which we fear the proliferation of meaning.

Thus, because Christian morals leave animals out of consideration ... therefore in philosophical morals they are of course at once outlawed; they are merely "things," simply means to ends of any sort; and so they are good for vivisection, for deer-stalking, bull-fights, horse-races, etc., and they may be whipped to death as they struggle along with heavy quarry carts. Shame on such a morality ... which fails to recognize the Eternal Reality immanent in everything that has life, and shining forth with inscrutable significance from all eyes that see the sun!

Science doesn't purvey absolute truth. Science is a mechanism. It's a way of trying to improve your knowledge of nature. It's a system for testing your thoughts against the universe and seeing whether they match. And this works, not just for the ordinary aspects of science, but for all of life. I should think people would want to know that what they know is truly what the universe is like, or at least as close as they can get to it.

They pronounce absurdly who thus speak, as the Pythagoreans assert: for at the same time they make the infinite to be essence, and distribute it into parts.

It is not that I am mad, it is only that my head is different from yours.

Their worship was not paid to the demon which such a being as they imagined would really be, but to their own idea of excellence. The evil is, that such a belief keeps the ideal wretchedly low; and opposes the most obstinate resistance to all thought which has a tendency to raise it higher. Believers shrink from every train of ideas which would lead the mind to a clear conception and an elevated standard of excellence, because they feel (even when they do not distinctly see) that such a standard would conflict with many of the dispensations of nature, and with much of what they are accustomed to consider as the Christian creed.

But it is clear there is a difference in the ends proposed: for in some cases they are activities, and in others results beyond the mere activities, and where there are certain ends beyond and beside the actions, the results are naturally superior to the activities. Now, as there are numerous kinds of actions and numerous arts and sciences, it follows that the ends are also various. Thus the end of the healing art is health, of ship-building ships, of strategy victory, of economy wealth.

Economic man deals with the "real world" in all its complexity. Administrative man recognizes that the world he perceives is a drastic simplified model... He makes his choices using a simple picture of the situation that takes into account just a few of the factors that he regards as most relevant and crucial.

The slaves of developed industrial civilization are sublimated slaves.

Navigation brought man face to face with the uncertainty of destiny, where each is left to himself and every departure might always be the last. The madman on his crazy boat sets sail for the other world, and it is from the other world that he comes when he disembarks. This enforced navigation is both rigorous division and absolute Passage, serving to underline in real and imaginary terms the liminal situation of the mad in medieval society. It was a highly symbolic role, made clear by the mental geography involved, where the madman was confined at the gates of the cities. His exclusion was his confinement, and if he had no prison other than the threshold itself he was still detained at this place of passage. In a highly symbolic position he is placed on the inside of the outside, or vice versa. A posture that is still his today, if we admit that what was once the visible fortress of social order is now the castle of our own consciousness.

The effectiveness of political and religious propaganda depends upon the methods employed, not upon the doctrines taught. These doctrines may be true or false, wholesome or pernicious-it makes little or no difference.

Even Darwin's natural selection only predicts that survivors will be fit enough, that is, fitter than their losing competitors; it postulates satisficing, not optimizing.

For the inquisition of Final Causes is barren, and like a virgin consecrated to God produces nothing.

The entire history of social improvement has been a series of transitions, by which one custom or institution after another, from being a supposed primary necessity of social existence, has passed into the rank of an universally stigmatized injustice and tyranny. So it has been with the distinctions of slaves and freemen, nobles and serfs, patricians and plebeians; and so it will be, and in part already is, with the aristocracies of colour, race, and sex.

Yet a man may love a paradox, without losing either his wit or his honesty.

Inferiority is always with us, and merciless scorn of it is the keynote of the military temper.

All who say the same things do not possess them in the same manner; and hence the incomparable author of the Art of Conversation pauses with so much care to make it understood that we must not judge of the capacity of a man by the excellence of a happy remark that we heard him make. ...let us penetrate, says he, the mind from which it proceeds... it will oftenest be seen that he will be made to disavow it on the spot, and will be drawn very far from this better thought in which he does not believe, to plunge himself into another, quite base and ridiculous.

There was a time when religion was kept secret from popular belief within the mystery cults like a holy fire, sharing a common sanctuary with philosophy. The legends of antiquity name the earliest philosophers as the originators of these mystery cults, from which the most enlightened among the later philosophers, notably Plato, liked to educe their divine teachings. At that time philosophers still had the courage and the right to discuss the singly great themes, the only ones worthy of philosophizing and rising above common knowledge.

Too much consistency is as bad for the mind as it is for the body. Consistency is contrary to nature, contrary to life. The only completely consistent people are the dead. Consistent intellectualism and spirituality may be socially valuable, up to a point; but they make, gradually, for individual death.

The way in which a society organizes the life of its members ... is one "project" of realization among others. But once the project has become operative in the basic institutions and relations, it tends to become exclusive and to determine the development of the society as a whole.

The normal process of life contains moments as bad as any of those which insane melancholy is filled with, moments in which radical evil gets its innings and takes its solid turn. The lunatic's visions of horror are all drawn from the material of daily fact. Our civilization is founded on the shambles, and every individual existence goes out in a lonely spasm of helpless agony. If you protest, my friend, wait till you arrive there yourself! ... Here on our very hearths and in our gardens the infernal cat plays with the panting mouse, or holds the hot bird fluttering in her jaws. Crocodiles and rattlesnakes and pythons are at this moment vessels of life as real as we are; their loathsome existence fills every minute of every day that drags its length along; and whenever they or other wild beasts clutch their living prey, the deadly horror which an agitated melancholiac feels is the literally right reaction on the situation.

The metaphor is perhaps one of man's most fruitful potentialities. Its efficacy verges on magic, and it seems a tool for creation which God forgot inside one of His creatures when He made him. All our other faculties keep us within the realm of the real, of what is already there. The most we can do is to combine things or to break them up. The metaphor alone furnishes an escape; between the real things, it lets emerge imaginary reefs, a crop of floating islands. A strange thing, indeed, the existence in man of this mental activity which substitutes one thing for another - from an urge not so much to get at the first as to get rid of the second.

If we already lived in a cruelty-free world, the notion of re-introducing suffering, exploitation and creatures eating each other would seem not so much frightful as unimaginable - no more seriously conceivable than reverting to surgery without anaesthesia today.

People no longer look at each other, but there are institutes for that. They no longer touch each other, but there is contactotherapy. They no longer walk, but they go jogging, etc. Everywhere one recycles lost faculties, or lost bodies, or lost sociality, or the lost taste for food.

With what consistency, or decency they complain so loudly of attempts to enslave them, while they hold so many hundred thousands in slavery; and annually enslave many thousands more, without any pretence of authority, or claim upon them?

The power of thought is the light of knowledge, the power of will is the energy of character, the power of heart is love. Reason, love and power of will are perfections of man.

All urgent calls he shall hear at once, but never put off; for when postponed, they will prove too hard or impossible to accomplish.

While the intellectual space does contain universal ideas, definitions, those definitions are detailed a posteriori. Truth corresponds with reality at a minimum. 

For tribal man, space was the uncontrollable mystery. For technological man it is time that occupies the same role.

There is no mystery in humans creation. Will performs this miracle. But at least there is no true creation without a secret.

It is the man of science, eager to have his every opinion regenerated, his every idea rationalized, by drinking at the fountain of fact, and devoting all the energies of his life to the cult of truth, not as he understands it, but as he does not yet understand it, that ought properly to be called a philosopher. To an earlier age knowledge was power - merely that and nothing more; to us it is life and the summum bonum. Emancipation from the bonds of self, of one's own prepossessions, importunately sought at the hands of that rational power before which all must ultimately bow, - this is the characteristic that distinguishes all the great figures of nineteenth-century science from those of former periods.

It is not to be supposed that she was, or that any one, at the age at which I first saw her, could be, all that she afterwards became. Least of all could this be true of her, with whom self-improvement, progress in the highest and in all senses, was a law of her nature; a necessity equally from the ardour with which she sought it, and from the spontaneous tendency of faculties which could not receive an impression or an experience without making it the source or the occasion of an accession of wisdom. Up to the time when I first saw her, her rich and powerful nature had chiefly unfolded itself according to the received type of feminine genius. To her outer circle she was a beauty and a wit, with an air of natural distinction, felt by all who approached her: to the inner, a woman of deep and strong feeling, of penetrating and intuitive intelligence, and of an eminently meditative and poetic nature.

Science must begin with myths, and with the criticism of myths.

Prejudice is an opinion without judgement.

When reason rules, money is a blessing.

Logic has borrowed, perhaps, the rules of geometry, without comprehending their force... it does not thence follow that they have entered into the spirit of geometry, and I should be greatly averse... to placing them on a level with that science that teaches the true method of directing reason.

Political questions are far too serious to be left to the politicians.
