We tend to believe the premises because we can see that their consequences are true, instead of believing the consequences because we know the premises to be true. But the inferring of premises from consequences is the essence of induction; thus the method in investigating the principles of mathematics is really an inductive method, and is substantially the same as the method of discovering general laws in any other science.

Living, loving, being natural or sincere-all these are spontaneous forms of behavior: they happen "of themselves" like digesting food or growing hair. As soon as they are forced they acquire that unnatural, contrived, and phony atmosphere which everyone deplores-weak and scentless like forced flowers and tasteless like forced fruit. Life and love generate effort, but effort will not generate them. Faith-in life, in other people, and in oneself-is the attitude of allowing the spontaneous to be spontaneous, in its own way and in its own time.

The inherent contradiction of human life has now reached an extreme degree of tension: on the one side there is the consciousness of the beneficence of the law of love, and on the other the existing order of life which has for centuries occasioned an empty, anxious, restless, and troubled mode of life, conflicting as it does with the law of love and built on the use of violence. This contradiction must be faced, and the solution will evidently not be favourable to the outlived law of violence, but to the truth which has dwelt in the hearts of men from remote antiquity: the truth that the law of love is in accord with the nature of man. But men can only recognize this truth to its full extent when they have completely freed themselves from all religious and scientific superstitions and from all the consequent misrepresentations and sophistical distortions by which its recognition has been hindered for centuries.

If it is permissible to write plays that are not intended to be seen, I should like to see who can prevent me from writing a book no one can read.

By Hercules, the state would have sustained a great loss if you had not brought him forth from the oblivion to which his two splendid qualities, eloquence and independence, had consigned him: he is now read, is popular, is received into men's hands and bosoms, and fears no old age: but as for those who butchered him, before long men will cease to speak even of their crimes, the only things by which they are remembered.

Being is only Being for Dasein.

No one should be judge in his own cause.

The will is not free to strive toward whatever is declared good.

With all great deceivers there is a noteworthy occurrence to which they owe their power. In the actual act of deception... they are overcome by belief in themselves. It is this which then speaks so miraculously and compellingly to those who surround them.

In order to be able to go on living it is possible that the bankrupt peoples will have to enter on a new path of self-denial, by curbing their covetousness and putting a check on the indefinite expansion of their wants, and by having smaller families.

A punishment that penalizes without forestalling is indeed called revenge.

I urge you to please notice when you are happy, and exclaim or murmur or think at some point, "If this isn't nice, I don't know what is."

Benevolence is the tranquil habitation of man, and righteousness is his straight path.

To say that all philosophy is writing is, minimally, to say that it is never the transparent expression of thought.

Thrasyllus the Cynic begged a drachm of Antigonus. "That," said he, "is too little for a king to give." "Why, then," said the other, "give me a talent." "And that," said he, "is too much for a Cynic (or, for a dog) to receive."

The great end of life is not knowledge but action.

If you punish him for what he sees you practise yourself, he... will be apt to interpret it the peevishness and arbitrary imperiousness of a father, who, without any ground for it, would deny his son the liberty and pleasure he takes himself.

Cornered vessel without corners, strange cornered vessel, strange cornered vessel.

Speech and silence. We feel safer with a madman who talks than with one who cannot open his mouth.

Not to be content with Life is the unsatisfactory state of those which destroy themselves; who being afraid to live, run blindly upon their own Death, which no Man fears by Experience.

The blindness of those who think it absurd to suppose that complex organic forms may have arisen by successive modifications out of simple ones becomes astonishing when we remember that complex organic forms are daily being thus produced. A tree differs from a seed immeasurably in every respect... Yet is the one changed in the course of a few years into the other: changed so gradually, that at no moment can it be said - Now the seed ceases to be, and the tree exists.

Man is a synthesis of psyche and body, but he is also a synthesis of the temporal and the eternal. In the former, the two factors are psyche and body, and spirit is the third, yet in such a way that one can speak of a synthesis only when the spirit is posited. The latter synthesis has only two factors, the temporal and the eternal. Where is the third factor? And if there is no third factor, there really is no synthesis, for a synthesis that is a contradiction cannot be completed as a synthesis without a third factor, because the fact that the synthesis is a contradiction asserts that it is not. What, then, is the temporal?

There is nothing more notable in Socrates than that he found time, when he was an old man, to learn music and dancing, and thought it time well spent.

And he arrives at the cogito ergo sum, which St. Augustine had already anticipated... "I think therefore I am," can only mean "I think, therefore I am a thinker"; this being of "I am," which is deduced from "I think," is merely a knowing; this being is a knowledge, but not life. And the primary reality is not that I think, but that I live, for those also live who do not think. Although this living may not be a real living. God! what contradictions when we seek to join in wedlock life and reason!

Warrior spirit is characterised by direct, clear and loyal relations, based on fidelity and honour and a sound instinct for the various dignities, which it can well distinguish: it opposes everything which is impersonal and trivial.

My aim is: to teach you to pass from a piece of disguised nonsense to something that is patent nonsense.

What fools these mortals be!

All states in the world, large or small, are cities of Heaven, and all people, young or old, honourable or humble, are its subjects; for they all graze oxen and sheep, feed dogs and pigs, and prepare clean wine and cakes to sacrifice to Heaven. Does this not mean that Heaven claims all and accepts offerings from all? Since Heaven does claim all and accepts offerings from all, what then can make us say that it does not desire men to love and benefit one another? Hence those who love and benefit others Heaven will bless. Those who hate and harm others Heaven will curse, for it is said that he who murders the innocent will be visited by misfortune. How else can we explain the fact that men, murdering each other, will be cursed by Heaven? Thus we are certain that Heaven desires to have men love and benefit one another and abominates to have them hate and harm one another.

A philosophical attempt to work out a universal history according to a natural plan directed to achieving the civic union of the human race must be regarded as possible and, indeed, as contributing to this end of Nature.

Situation seems to be the mould in which men's characters are formed.

Considering the optimistic turn taken by world trade AT THIS MOMENT...it is some consolation at least that the revolution has begun in Russia, for I regard the convocation of 'notables' to Petersburg as such a beginning. ... On the Continent revolution is imminent and will, moreover, instantly assume a socialist character.

The entire heaven, making its parts everywhere harmonize with him, is filled with spirits emanating out of the Sun. For this god is ruler of five orbits in the heavens, and whilst traversing three out of these orbits, he produces in three the Graces, themselves three in number, the remaining circles form the Scales to the Balance of supreme Necessity.

Many conservative writers have contended that the tendency to equality in modern social movements is the expression of envy. In this way they seek to discredit this trend, attributing it to collectively harmful impulses.

To aspire to be superhuman is a most discreditable admission that you lack the guts, the wit, the moderating judgment to be successfully and consummately human.

For on these matters we should not trust the multitude who say that none ought to be educated but the free, but rather to philosophers, who say that the educated alone are free.

Just you think first, and don't bother to speak afterward, either.

Count all wickedness foreign and alien.

The Life according to Reason consists herein, -that the Individual forget himself in the Race, place his own life in the life of the Race, and dedicate it thereto;-the Life opposed to Reason, on the contrary, consists in this, that the Individual think of nothing but himself, love nothing but himself and in relation to himself, and set his whole existence in his own personal well-being alone: -and since we may briefly call that which is according to Reason good, and that which is opposed to Reason evil, so there is but One Virtue, to forget one's own personality;-and but One Vice,-to make self the object of our thoughts.

Can the children of the bridechamber mourn, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and then shall they fast. No man putteth a piece of new cloth unto an old garment, for that which is put in to fill it up taketh from the garment, and the rent is made worse. Neither do men put new wine into old bottles: else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved.

When I obey a rule, I do not choose. I obey the rule blindly.

We, who are dying, are doing better, than they, who will live. For Crete doesn't need householders, she needs madmen like us. These madmen make Crete immortal.

The historical world, in so far as it is built, organized, and shaped by the conscious activity of thinking subjects, is a realm of mind. But the mind is fully realized and exists in its true form only when it indulges in its proper activity, namely, in art, religion, and philosophy.

I have always done things in my own way, which is at once the way that comes naturally to me, that is honest, sincere, genuine, and unforced; but also perverse, although you must remember that this word means per (through) verse (poetry), out-of-the-way and wayward, which is surely towards the way, and that to be queer-to "follow your own weird"-is wholeheartedly to accept your karma, or fate, or destiny, and thus to be odd in the service of God, "whose service," as the Anglican Book of Common Prayer declares, "is perfect freedom."

The question here is not, "How conscience ought to be guided? For Conscience is its own General and Leader; it is therefore enough that each man have one. What we want to know is, how conscience can be her own Ariadne, and disentangle herself from the mazes even of the most raveled and complicated casuistical theology. Here is an ethical proposition that stands in need of no proof: No Action May At Any Time Be Hazarded On The Uncertainty That Perchance It May Not Be Wrong (Quod dubitas, ne feceris! Pliny - which you doubt, then neither do) Hence the Consciousness, that Any Action I am about to perform is Right, is in itself a most immediate and imperative duty. What actions are right, - what wrong - is a matter for the understanding, not for conscience.

When the profits of trade happen to be greater than ordinary, over-trading becomes a general error both among great and small dealers.

As a human being it is just my nature to enjoy and share philosophy. I do this in the same way that some birds are eagles and some doves, some flowers lilies and some roses.

The Reformation was a popular uprising, and for a century and a half drenched Europe in blood. The beginnings of the Scientific movement were confined to a minority among the intellectual elite.... The worst that happened to men of science was that Galileo suffered an honorable detention and a mild reproof, before dying peacefully in his bed. The way in which the persecution of Galileo has been remembered is a tribute to the quiet commencement of the most intimate change in outlook which the human race had yet encountered. Since a babe was born in a manger, it may be doubted whether so great a thing has happened with so little stir.

I believe that freedom is not a constant attribute that "we have" or "we don't have"; perhaps there is only one reality: the act of liberating ourselves in the process of using choices. Every step in life that heightens the maturity of man heightens his ability to choose the freeing alternative. I believe that "freedom of choice" is not always equal for all men at every moment. The man with an exclusively necrophilic orientation; who is narcissistic; or who is symbiotic-incestuous, can only make a regressive choice. The free man, freed from irrational ties, can no longer make a regressive choice.

He that uses his words loosely and unsteadily will either not be minded or not understood.
