The aim of science is to seek the simplest explanations of complex facts. We are apt to fall into the error of thinking that the facts are simple because simplicity is the goal of our quest. The guiding motto in the life of every natural philosopher should be, "Seek simplicity and distrust it."

Knowing that certain nights whose sweetness lingers will keep returning to the earth and sea after we are gone, yes, this helps us to die.

It costs a beautiful person no exertion to paint her image on our eyes; yet how splendid is that benefit! It costs no more for a wise soul to convey his quality to other men.

This method of mental training is, therefore, the immediate preparation for the moral; it completely destroys the root of immorality by never allowing sensuous enjoyment to become the motive. Formerly, that was the first motive to be stimulated and developed, because it was believed that otherwise the pupil could not be influenced or controlled at all.

Instead of noble men, let us have noble villages of men. If it is necessary, omit one bridge over the river, round a little there and throw one arch at least over the darker gulf of ignorance which surrounds us.

Our elucidations of the preliminary concept of phenomenology show that its essential character does not consist in its actuality as a philosophical "movement." Higher than actuality stands possibility. We can understand phenomenology solely by seizing upon it as a possibility.

A novel is never anything but a philosophy put into images. And in a good novel, the whole of the philosophy has passed into the images. But if once the philosophy overflows the characters and action, and therefore looks like a label stuck on the work, the plot loses its authenticity and the novel its life. Nevertheless, a work that is to last cannot dispense with profound ideas. And this secret fusion between experiences and ideas, between life and reflection on the meaning of life, is what makes the great novelist.

Imaginary pains are by far the most real we suffer, since we feel a constant need for them and invent them because there is no way of doing without them.

It is told that those who first brought out the irrationals from concealment into the open perished in shipwreck, to a man. For the unutterable and the formless must needs be concealed. And those who uncovered and touched this image of life were instantaneously destroyed and shall remain forever exposed to the play of the eternal waves.

We sometimes imagine, under the influence of Spenglerian philosophy or some other kind of "historical morphology," that we live in a similar age [to the Romans], the last witnesses of a condemned civilization. But condemned by whom? Not by God, but by some supposed "historical laws." For although we do not know any historical laws, we are in fact able of inventing them quite freely, and such laws, once invented, can then be realized in the form of self-fulfilling prophecies.

You are of all my friends the one who illustrates pragmatism in its most needful forms. You are a jewel of pragmatism.

Each generation is a filter, a sieve; good genes tend to fall through the sieve into the next generation; bad genes tend to end up in bodies that die young or without reproducing.

To explain the origin of the DNA/protein machine by invoking a supernatural Designer is to explain precisely nothing, for it leaves unexplained the origin of the Designer.

We are all made for mutual assistance, as the feet, the hands, and the eyelids, as the rows of the upper and under teeth, from whence it follows that clashing and opposition is perfectly unnatural.

The compassionate are not rich; therefore, the rich are not compassionate.

Perhaps there is nobody who would sacrifice his life for the sake of maintaining that the three angles of a triangle are together equal to two right angles, for such a truth does not demand the sacrifice of our life; but, on the other hand, there are many who have lost their lives for the sake of maintaining their religious faith. Indeed, it is truer to say that martyrs make faith than that faith makes martyrs. For faith is not the mere adherence of the intellect to an abstract principle; it is not the recognition of a theoretical truth, the process in which the will merely sets in motion our faculty of comprehension; faith is an act of the will - it is a movement of the soul towards a practical truth, towards a person, towards something that makes us not merely comprehend life, but that makes us live.

No difference of rank, position, or birth, is so great as the gulf that separates the countless millions who use their head only in the service of their belly, in other words, look upon it as an instrument of the will, and those very few and rare persons who have the courage to say: No! my head is too good for that; it shall be active only in its own service; it shall try to comprehend the wondrous and varied spectacle of this world and then reproduce it in some form, whether as art or as literature, that may answer to my character as an individual.

Men have made an idol of luck as an excuse for their own thoughtlessness. Luck seldom measures swords with wisdom. Most things in life quick wit and sharp vision can set right.

To conceive the good, in fact, is not sufficient; it must be made to succeed among men. To accomplish this less pure paths must be followed.

The old dualistic notion of mind and matter, so prominent in Cartesianism, as two radically different kinds of substance, will hardly find defenders to-day. Rejecting this, we are driven to some form of hylopathy, otherwise called monism.

In fact, contempt for happiness is usually contempt for other people's happiness, and is an elegant disguise for hatred of the human race.

We need to augment and amend the existing body of classical and neoclassical economic theory to achieve a more realistic picture of economic process.

Inspect every piece of pseudoscience and you will find a security blanket, a thumb to suck, a skirt to hold. What does the scientist have to offer in exchange? Uncertainty! Insecurity!

Not to feel exasperated or defeated or despondent because your days aren't packed with wise and moral actions. But to get back up when you fail, to celebrate behaving like a human-however imperfectly-and fully embrace the pursuit you've embarked on.

Our Constitution, by its separation of powers and its system of checks and balances, acts as a restraint upon efficiency by denying exclusive power to any branch of government. The logic of governmental efficiency, unchecked, runs straight on, not only to dictatorship, but also to torture, assassination, and other abominations.

The extreme nature of dominant-end views is often concealed by the vagueness and ambiguity of the end proposed.

An optimistic view of the future would indicate that before long, the clear necessity of expanding humanity's horizons would cause ... space settlements to be built. The construction would also serve as a great project that not only would be clearly of great benefit, but might induce human cooperation in something large enough to fire the heart and mind, and make people forget the petty quarrels that have engaged them for thousands of years in wars over insignificant scraps of earthly territory.

Although I consider our political world to be the best of which we have any historical knowledge, we should beware of attributing this fact to democracy or to freedom. Freedom is not a supplier who delivers goods to our door. Democracy does not ensure that anything is accomplished - certainly not an economic miracle. It is wrong and dangerous to extol freedom by telling people that they will certainly be all right once they are free. How someone fares in life is largely a matter of luck or grace, and to a comparatively small degree perhaps also of competence, diligence, and other virtues. The most we can say of democracy or freedom is that they give our personal abilities a little more influence on our well-being.

O world, thou choosest not the better part! It is not wisdom to be only wise, And on the inward vision close the eyes, But it is wisdom to believe the heart. Columbus found a world, and had no chart, Save one that faith deciphered in the skies; To trust the soul's invincible surmise Was all his science and his only art.

One day, observing a child drinking out of his hands, he cast away the cup from his wallet with the words, "A child has beaten me in plainness of living."

"The real saint", Baudelaire pretends to think, "is he who flogs and kills people for their own good." His argument will be heard. A race of real saints is beginning to spread over the earth for the purposes of confirming these curious conclusions about rebellion.

The process of being brought up, however well it is done, cannot fail to offend.

Those who forget good and evil and seek only to know the facts are more likely to achieve good than those who view the world through the distorting medium of their own desires.

Philip being arbitrator betwixt two wicked persons, he commanded one to fly out of Macedonia and the other to pursue him.

On our earth we can only love with suffering and through suffering. We cannot love otherwise, and we know of no other sort of love. I want suffering in order to love. I long, I thirst, this very instant, to kiss with tears the earth that I have left, and I don't want, I won't accept life on any other!"

You may break your heart, but men will still go on as before.

The male has more teeth than the female in mankind, and sheep, and goats, and swine. This has not been observed in other animals.

We may assume the superiority ceteris paribus [all things being equal] of the demonstration which derives from fewer postulates or hypotheses—in short from fewer premisses; for... given that all these are equally well known, where they are fewer knowledge will be more speedily acquired, and that is a desideratum. The argument implied in our contention that demonstration from fewer assumptions is superior may be set out in universal form...

All the entertainment and talk of history is nothing almost but fighting and killing: and the honour and renown that is bestowed on conquerers (who for the most part are but the great butchers of mankind) farther mislead growing youth, who by this means come to think slaughter the laudible business of mankind, and the most heroick of virtues. By these steps unnatural cruelty is planted in us; and what humanity abhors, custom reconciles and recommends to us, by laying it in the way to honour. Thus, by fashioning and opinion, that comes to be a pleasure, which in itself neither is, nor can be any.

We are so captivated by and entangled in our subjective consciousness that we have forgotten the age-old fact that God speaks chiefly through dreams and visions.

Junz found revulsion growing strong within him. A planet full of people meant nothing against the dictates of economic necessity!

If the world is a precipitation of human nature, so to speak, then the divine world is a sublimation of the same. Both occur in one act. No precipitation without sublimation. What goes lost there in agility, is won here.

The healthy man does not torture others-generally it is the tortured who turn into torturers.

Morals excite passions, and produce or prevent actions. Reason of itself is utterly impotent in this particular. The rules of morality, therefore, are not conclusions of our reason.

When we see a great man desiring power instead of his real goal we soon recognize that he is sick, or more precisely that his attitude to his work is sick. He overreaches himself, the work denies itself to him, the incarnation of the spirit no longer takes place, and to avoid the threat of senselessness he snatches after empty power. This sickness casts the genius on to the same level as those hysterical figures who, being by nature without power, slave for power, in order that they may enjoy the illusion that they are inwardly powerful, and who in this striving for power cannot let a pause intervene, since a pause would bring with it the possibility of self-reflection and self-reflection would bring collapse.

It is not sufficient to observe our mysteries in the seclusion of our lodge-we must act-act! We are drowsing, but we must act. (Pierre raised his notebook and began to read.) For the dissemination of pure truth and to secure the triumph of virtue," he read, "we must cleanse men from prejudice, diffuse principles in harmony with the spirit of the times, undertake the education of the young, unite ourselves in indissoluble bonds with the wisest men, boldly yet prudently overcome superstitions, infidelity, and folly, and form of those devoted to us a body linked together by unity of purpose and possessed of authority and power.

All those countless battles-those endless, and... for the greater part, useless wars, of which... fills up for so many thousand years... are but little atoms compared with the great whole of human destiny.

How many mistakes power has committed! And how often has it ignored the means to conserve itself! Man is insatiable for power; he is infinite in his desires, and, always discontented with what he has, he loves only what he has not. People complain about the despotism of princes; they should complain about that of man. We are all born despots, from the most absolute monarch of Asia to the child who smothers a bird with his hand for the pleasure of seeing something in the world weaker than himself. There is no man who does not abuse power, and experience proves that the most abominable despots, if they come to seize the sceptre, will be precisely those who rant against despotism.
