Do not be too moral. You may cheat yourself out of much life so. Aim above morality. Be not simply good; be good for something.

The reproduction of mankind is a great marvel and mystery. Had God consulted me in the matter, I should have advised him to continue the generation of the species by fashioning them of clay, in the way Adam was fashioned.

To be sure, risks abound; but no one is proposing compassionate stewardship of ecosystems by philosophers. Humans are capable of choosing our own future pain-sensitivity too; but any species-wide genomic shift in human pain tolerance will depend on the willingness of prospective parents to use preimplantation genetic screening.

Relativism is a product of the modern historical-sociological procedure which is based on the recognition that all historical thinking is bound up with the concrete position in life of the thinker [Standortsgebundenheit des Denkers]. But relativism combines this historical-sociological insight with an older theory of knowledge which was as yet unaware of the interplay between conditions of existence and modes of thought, and which modelled its knowledge after static prototypes such as might be exemplified by the proposition 2 x 2 = 4. This older type of thought, which regarded such examples as the model of all thought, was necessarily led to the rejection of all those forms of knowledge which were dependent upon the subjective standpoint and the social situation of the knower, and which were, hence, merely "relative".

The Presbyterian clergy are loudest, the most intolerant of all sects, the most tyrannical, and ambitious; ready at the word of the lawgiver, if such a word could be now obtained, to put the torch to the pile, and to rekindle in this virgin hemisphere, the flames in which their oracle Calvin consumed the poor Servetus, because he could not find in his Euclid the proposition which has demonstrated that three are one, and one is three, nor subscribe to that of Calvin that magistrates have a right to exterminate all heretics to Calvinistic creed.

The pursuit of knowledge is, I think, mainly actuated by love of power. And so are all advances in scientific technique. In politics, also, a reformer may have just as strong a love of power as a despot. It would be a complete mistake to decry love of power altogether as a motive. Whether you will be led by this motive to actions which are useful, or to actions which are pernicious, depends upon the social system, and upon your capacities.

Whoever finishes a revolution only halfway, digs his own grave.

Absolute freedom mocks at justice. Absolute justice denies freedom. To be fruitful, the two ideas must find their limits in each other. 

We cannot credit our enjoyment of a flower or of the atmosphere of a room to an autonomous esthetic instinct. Man's esthetic responsiveness relates in its prehistory to various forms of idolatry; his belief in the goodness or sacredness of a thing precedes his enjoyment of its beauty. The applies no less to such concepts as freedom and humanity.

Idleness is only fatal to the mediocre.

Bless Madison Ave for restoring the magical art of the cavemen to suburbia.

If the brutes have consciousness and no souls, then it is clear that, in them, consciousness is a direct function of material changes; while, if they possess immaterial subjects of consciousness, or souls, then, as consciousness is brought into existence only as the consequence of molecular motion of the brain, it follows that it is an indirect product of material changes. The soul stands related to the body as the bell of a clock to the works, and consciousness answers to the sound which the bell gives out when it is struck.

It may be confidently asserted that no man chooses evil because it is evil; he only mistakes it for happiness, the good he seeks. And the desire of rectifying these mistakes, is the noble ambition of an enlightened understanding, the impulse of feelings that Philosophy invigorates.

It is certainly not a matter of indifference whether I learn something without effort or finally arrive at it myself through my system of thought. In the latter case everything has roots, in the former it is merely superficial.

In order to enjoy the inestimable benefits that the liberty of the press ensures, it is necessary to submit to the inevitable evils it creates.

Perhaps the most valuable result of all education is the ability to make yourself do the thing you have to do, when it ought to be done, whether you like it or not; it is the first lesson that ought to be learned; and, however early a man's training begins, it is probably the last lesson that he learns thoroughly.

Humans are prone to status quo bias. So let's do a thought-experiment. Imagine we stumble across an advanced civilisation that has abolished predation, disease, famine, and all the horrors of primitive Darwinian life. The descendants of archaic lifeforms flourish unmolested in their wildlife parks - free living, but not "wild". Should we urge scrapping their regime of compassionate stewardship of the living world - and a return to asphyxiation, disembowelling and being eaten alive? Or is a happy biosphere best conserved intact? Reply to "Should humans wipe out all carnivorous animals so the succeeding generations of herbivores can live in peace?"

Self-preservation has frequently knuckled under to that tremendous yearning to get even.

The example of the Jews, in many things, may not be imitated by us; they had not only orders to cut off several nations altogether, but if they were obliged to war with others, and conquered them, to cut off every male; they were suffered to use polygamy and divorces, and other things utterly unlawful to us under clearer light.

Use these rules then, and trouble thyself about nothing else.

It is a rough road that leads to the heights of greatness.

The present state of France was ten times worse than a tyranny. The new constitution was said to be an experiment but the assertion was not true. It had already been tried, and had been found to be only productive of evils. They would go on from tyranny to tyranny, from oppression to oppression, till at last the whole system would terminate in the destruction of that miserable and deluded people... He sincerely hoped that no member of that House would ever barter the constitution of this country, the eternal jewel of their souls, for a wild and visionary system, which could only lead to confusion and disorder.

He would be the finer gentleman that should leave the world without having tasted of lying or pretence of any sort, or of wantonness or conceit.

I shall never be ashamed of citing a bad author if the line is good.

If one examines the reason why certain works of art offend us, one is likely to find that the cause is that there is no personally felt emotion guiding the selecting the assembling of the materials presented. We derive the impression that the artist, say the author of a novel, is trying to regulate by conscious intent the nature of the emotion aroused. We are irritated by a feeling that he is manipulating materials to secure an effect decided upon in advance. The facets of the work, the variety so indispensable to it, are held together by some external force. The movement of the parts and the conclusion disclose no logical necessity. The author, not the subject matter, is the arbiter.

The soul contains few secrets and longings which cannot be sensibly discussed, analyzed, and polled. Solitude, the very condition which sustained the individual against and beyond his society, has become technically impossible. Logical and linguistic analysis demonstrate that the old metaphysical problems are illusory problems; the quest for the "meaning" of things can be reformulated as the quest for the meaning of words, and the established universe of discourse and behavior can provide perfectly adequate criteria for the answer.

Common sense doesn't have the last word in ethics or anywhere else, but it has, as J. L. Austin said about language, the first word: it should be examined before it is discarded.

Now, justification in this life is given to us according to these three things: first by the laver of regeneration by which all sins are forgiven; then, by a struggle with the faults from whose guilt we have been absolved; the third, when our prayer is heard, in which we say: Forgive us our debts, because however bravely we fight against our faults, we are men; but the grace of God so aids as we fight in this corruptible body that there is reason for His hearing us as we ask forgiveness.

Hitler never intended to defend 'the West' against Bolshevism but always remained ready to join 'the Reds' for the destruction of the West, even in the middle of the struggle against Soviet Russia.

Wisdom and contrivance are shown in overcoming difficulties, so there is no place for them in a Being for whom no difficulties exist.

It is an axiom in my mind, that our liberty can never be safe but in the hands of the people themselves, and that too of the people with a certain degree of instruction. This it is the business of the State to effect, and on a general plan.

No nation which has sunk into this state of dependence can raise itself out of it by the means which have usually been adopted hitherto. Since resistance was useless to it when it was still in possession of all its powers, what can such resistance avail now that it has been deprived of the greater part of them?

Espousing the melancholy of ancient symbols, I would have freed myself.

Do not tell lies, and do not do what you hate, for all things are plain in the sight of Heaven. For nothing hidden will not become manifest, and nothing covered will remain without being uncovered.

No longer ask me for my program: isn't breathing one?

Conservatives have, on the whole, accepted nationality as a sphere of local duties and loyalties, defining an inheritance and a community that has a right to pass on its values from generation to generation. The nation may indeed be the best that we now have, by way of a society linking the dead to the unborn, in the manner extolled by Burke. And for this very reason it arouses the hostility of liberals, who are constantly searching for a place outside loyalty and obedience, from which all human claims can be judged. Hence, in the conflicts of our times, while conservatives leap to the defense of the nation and its interests, wishing to maintain its integrity and to enforce its law, liberals advocate transnational initiatives, international courts, and doctrines of universal rights, all of which, they believe, should stand in judgment over the nation and hold it to account.

I foresee the day when we shall read nothing but telegrams and prayers.

The moment we choose to love we begin to move against domination, against oppression. The moment we choose to love we begin to move towards freedom, to act in ways that liberate ourselves and others.

I know of no country, indeed, where the love of money has taken stronger hold on the affections of men, and where the profounder contempt is expressed for the theory of the permanent equality of property.

Try not to have Emily exposed to hours and hours of TV. It is a vile drug which permeates the nervous system, especially in the young.

The real question is not whether machines think but whether men do. The mystery which surrounds a thinking machine already surrounds a thinking man.

Let us not violate the RIGHT of the artist to express exclusively his own experiences and introspections, disregarding everything that happens in the world beyond. Let us not DEMAND of the artist, but - reproach, beg, urge and entice him - that we may be allowed to do. After all, only in part does he himself develop his talent; the greater part of it is blown into him at birth as a finished product, and the gift of talent imposes responsibility on his free will. Let us assume that the artist does not OWE anybody anything: nevertheless, it is painful to see how, by retiring into his self-made worlds or the spaces of his subjective whims, he CAN surrender the real world into the hands of men who are mercenary, if not worthless, if not insane.

A spontaneous, passionate, yet just, true-meaning man! Full of wild faculty, fire and light; of wild worth, all uncultured; working out his life-task in the depths of the Desert there.

The social conditions that nourished and made use of this ideology can still revive; perhaps - who knows? - the virus is dormant, waiting for the next opportunity. Dreams about the perfect society belong to the enduring stock of civilization.

...undefiled by pleasures, invulnerable to any pain, untouched by arrogance, unaffected by meanness, an athlete in the greatest of all contests-the struggle not to be overwhelmed by anything that happens.
