Truth and falsity are the most fundamental terms of rational criticism, and any adequate philosophy must give some account of these, or failing that, show that they can be dispensed with.

I am dreaming ...? Let me dream, if this dream is my life. Do not awaken me from it. I believe in the immortal origin of this yearning for immortality, which is the very substance of my soul. But do I really believe in it ...? And wherefore do you want to be immortal? you ask me, wherefore? Frankly, I do not understand the question, for it is to ask the reason of the reason, the end of the end, the principle of the principle.

It is very strange that men should deny a creator and yet attribute to themselves the power of creating eels.

It is the first step in sociological wisdom, to recognize that the major advances in civilization are processes which all but wreck the societies in which they occur:-like unto an arrow in the hand of a child. The art of free society consists first in the maintenance of the symbolic code; and secondly in fearlessness of revision, to secure that the code serves those purposes which satisfy an enlightened reason. Those societies which cannot combine reverence to their symbols with freedom of revision, must ultimately decay either from anarchy, or from the slow atrophy of a life stifled by useless shadows.

Those things which now most engage the attention of men, as politics and the daily routine, are, it is true, vital functions of human society, but should be unconsciously performed, like the corresponding functions of the physical body. They are infra-human, a kind of vegetation. I sometimes awake to a half-consciousness of them going on about me, as a man may become conscious of some of the processes of digestion in a morbid state, and so have the dyspepsia, as it is called.

All laws are... deduced from experiment; but to enunciate them, a special language is needful... ordinary language is too poor...This... is one reason why the physicist can not do without mathematics; it furnishes him the only language he can speak. And a well-made language is no indifferent thing;...the analyst, who pursues a purely esthetic aim, helps create, just by that, a language more fit to satisfy the physicist....law springs from experiment, but not immediately. Experiment is individual, the law deduced from it is general; experiment is only approximate, the law is precise...In a word, to get the law from experiment, it is necessary to generalize... But how generalize? ...in this choice what shall guide us?It can only be analogy. ...What has taught us to know the true profound analogies, those the eyes do not see but reason divines?It is the mathematical spirit, which disdains matter to cling only to pure form.

Wherever Macdonald sits, there is the head of the table.

We have come to see that Huxley was right when he said that "a man's worst difficulties begin when he is able to do as he likes." The evidences of these greater difficulties lie all about us: in the brave and brilliant atheists who have defied the Methodist God, and have become very nervous; in the women who have emancipated themselves from the tyranny of fathers, husbands, and homes, and with the intermittent but expensive help of a psychoanalyst, are now enduring liberty as interior decorators; in the young men and women who are world-weary at twenty-two; in the multitudes who drug themselves with pleasure; in the crowds enfranchised by the blood of heroes who cannot be persuaded to take an interest in their destiny; in the millions, at last free to think without fear of priest or policeman, who have made the moving pictures and the popular newspapers what they are.

Anxiety may be compared with dizziness. He whose eye happens to look down into the yawning abyss becomes dizzy. But what is the reason for this? It is just as much in his own eye as in the abyss, for suppose he had not looked down. Hence, anxiety is the dizziness of freedom, which emerges when the spirit wants to posit the synthesis and freedom looks down into its own possibility, laying hold of finiteness to support itself. Freedom succumbs to dizziness. Further than this, psychology cannot and will not go. In that very moment everything is changed, and freedom, when it again rises, sees that it is guilty. Between these two moments lies the leap, which no science has explained and which no science can explain. He who becomes guilty in anxiety becomes as ambiguously guilty as it is possible to become.

Atheists have the intellectual courage to accept reality for what it is: wonderfully and shockingly explicable. As an atheist, you have the moral courage to live to the full the only life you're ever going to get: to fully inhabit reality, rejoice in it, and do your best finally to leave it better than you found it.

A major task in organizing is to determine, first, where the knowledge is located that can provide the various kinds of factual premises that decisions require.

'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.

How did they meet? By chance, like everybody ... Where did they come from? From the nearest place. Where were they going? Do we know where we are going?

I believe in intuitions and inspirations. I sometimes feel that I am right. I do not know that I am. When two expeditions of scientists, financed by the Royal Academy, went forth to test my theory of relativity, I was convinced that their conclusions would tally with my hypothesis. I was not surprised when the eclipse of May 29, 1919, confirmed my intuitions. I would have been surprised if I had been wrong.

To rule the imperial population, behold our vocation.

On eroding, ecologically degraded, increasingly toxic landscapes, worked by failing or subsidy-dependent farmers and by the cheap labor of migrants, we have erected the tottering tower of "agribusiness," which prospers and "feeds the world" (incompletely and temporarily) by undermining its own foundations.

The charming landscape which I saw this morning, is indubitably made up of some twenty or thirty farms. Miller owns this field, Locke that, and Manning the woodland beyond. But none of them owns the landscape. There is a property in the horizon which no man has but he whose eye can integrate all the parts, that is, the poet. This is the best part of these men's farms, yet to this their warranty-deeds give no title. To speak truly, few adult persons can see nature. Most persons do not see the sun. At least they have a very superficial seeing. The sun illuminates only the eye of the man, but shines into the eye and the heart of the child. The lover of nature is he whose inward and outward senses are still truly adjusted to each other; who has retained the spirit of infancy even into the era of manhood. His intercourse with heaven and earth, becomes part of his daily food.

Those least responsible for climate change are worst affected by it.

Cease therefore to be dismayed by the mere novelty and so to reject reason from your mind with loathing: weigh the questions rather with keen judgment and if they seem to you to be true, surrender, or if the thing is false, gird yourself to the encounter.

A moral point of view too often serves as a substitute for understanding in technological matters.

I do not believe that science per se is an adequate source of happiness, nor do I think that my own scientific outlook has contributed very greatly to my own happiness, which I attribute to defecating twice a day with unfailing regularity.

Besides, we should never attempt to balance anybody's misery against somebody else's happiness.

You do not know where death awaits you; so be ready for it everywhere.

What is new in our time is the increased power of the authorities to enforce their prejudices.

Further, it will not be amiss to distinguish the three kinds and, as it were, grades of ambition in mankind. The first is of those who desire to extend their own power in their native country, a vulgar and degenerate kind. The second is of those who labor to extend the power and dominion of their country among men. This certainly has more dignity, though not less covetousness. But if a man endeavor to establish and extend the power and dominion of the human race itself over the universe, his ambition (if ambition it can be called) is without doubt both a more wholesome and a more noble thing than the other two. Now the empire of man over things depends wholly on the arts and sciences. For we cannot command nature except by obeying her.

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

Everything is the work of imagination, and... all the faculties of the soul can be correctly reduced to pure imagination...

I've got a one-dimensional mind.

From the point of view of semantics, errors must be accidents: if in the extension of "horse" there are no cows, then it cannot be required for the meaning of "horse" that cows be called horses. On the other hand, if "horse" did not mean that which it means, and if it were an error for horses, it would never be possible for a cow to be called "horse." Putting the two things together, it can be seen that the possibility of falsely saying "this is a horse" presupposes the existence of a semantic basis for saying it truly, but not vice versa. If we put this in terms of the crude causal theory, the fact that cows cause one to say "horse" depends on the fact that horses cause one to say "horse"; but the fact that horses cause one to say "horse" does not depend on the fact that cows cause one to say "horse"...

For two thousand years, Jesus has revenged himself on us for not having died on a sofa.

Men sometimes submit to shame, to tyranny, to conquest, but they never long suffer anarchy. There is no people so barbarous that they escape this general law of humanity.

Awareness of time: assault on time . . .

By committing a crime, a man places himself, of his own accord, outside the chain of eternal obligations which bind every human being to every other one. Punishment alone can weld him back again; fully so, if accompanied by consent on his part; otherwise only partially so. Just as the only way of showing respect for somebody suffering from hunger is to give him something to eat, so the only way of showing respect for somebody who has placed himself outside the law is to reinstate him inside the law by subjecting him to the punishment ordained by law.The need for punishment is not satisfied where, as is generally the case, the penal code is merely a method of exercising pressure through fear.

For some identify happiness with virtue, some with practical wisdom, others with a kind of philosophic wisdom, others with these, or one of these, accompanied by pleasure or not without pleasure; while others include also external prosperity. Now ... it is not probable that these should be entirely mistaken, but rather that they should be right in at least some one respect or even in most respects.

For whoever has what he has from the God himself clearly has it at first hand; and he who does not have it from the God himself is not a disciple. Let us assume that it is otherwise, that the contemporary generation of disciples had received the condition from the God, and that the subsequent generations were to receive it from these contemporaries, what would follow?

Art is a human activity consisting in this, that one consciously, by means of certain external symbols, conveys to others the feelings one has experienced, whereby people so infected by these feelings, also experience them.

It is better to lose health like a spendthrift than to waste it like a miser. It is better to live and be done with it, than to die daily in the sick-room.

Seek after the good, and with much toil shall ye find it; the evil turns up of itself without your seeking it.

For in every country of the world, I believe, the avarice and injustice of princes and sovereign states, abusing the confidence of their subjects, have by degrees diminished the real quantity of metal, which had been originally contained in their coins.

What thinkest thou, Simon? of whom do the kings of the earth take custom or tribute? of their own children, or of strangers?

That the outer man is a picture of the inner, and the face an expression and revelation of the whole character, is a presumption likely enough in itself, and therefore a safe one to go on; borne out as it is by the fact that people are always anxious to see anyone who has made himself famous .... Photography ... offers the most complete satisfaction of our curiosity.

Bad company is as instructive as licentiousness. One makes up for the loss of one's innocence with the loss of one's prejudices.

If there may be doubts for men and for a childless woman as to the way to, fulfil the will of God, for a mother that path is firmly and clearly defined, and if she fulfils it humbly with a simple heart she stands on the highest point of perfection a human being can attain, and becomes for all a model of that complete performance of God's will which all desire. Only a mother can before her death tranquilly say to Him who sent her into this world, and Whom she has served by bearing and bringing up children whom she has loved more than herself - only she having served Him in the way appointed to her can say with tranquillity, Now lettest Thou Thy servant depart in peace. And that is the highest perfection to which, as to the highest good, men aspire.

The world is all that is the case.

I am obliged to confess that I do not regard the abolition of slavery as a means of warding off the struggle of the two races in the Southern states. The Negroes may long remain slaves without complaining; but if they are once raised to the level of freemen, they will soon revolt at being deprived of almost all their civil rights; and as they cannot become the equals of the whites, they will speedily show themselves as enemies.

For Genet, Beauty will be the offensive weapon that will enable him to beat the just on their own ground: that of value.
