I have said these things to you so that by means of me you may have peace. In the world you will have tribulation, but take courage! I have conquered the world.

It really comes down to parsimony, economy of explanation. It is possible that your car engine is driven by psychokinetic energy, but if it looks like a petrol engine, smells like a petrol engine and performs exactly as well as a petrol engine, the sensible working hypothesis is that it is a petrol engine.

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.

If there be such a thing as truth, it must infallibly be struck out by the collision of mind with mind.

The intellect is at home in that which is fixed only because it is done and over with, for intellect is itself just as much a deposit of past life as is the matter to which it is congenial. Intuition alone articulates in the forward thrust of life and alone lays hold of reality.

Notwithstanding their attacks on the basic conception of rationalism, on synthetic a priori judgments, that is, material propositions that cannot be contradicted by any experience, the empiricist posits the forms of being as constant.

A whole is that which has beginning, middle, and end.

The solution is, that we do not see the image on the retina at all, we only see by means of it.

A man does not kill himself, as is commonly supposed, in a fit of madness but rather in a fit of unendurable lucidity, in a paroxysm which may, if so desired, be identified with madness; for an excessive perspicacity, carried to the limit and of which one longs to be rid at all costs, exceeds the context of reason.

Nowadays, to say that we are clever animals is not to say something philosophical and pessimistic but something political and hopeful - namely, if we can work together, we can make ourselves into whatever we are clever and courageous enough to imagine ourselves becoming. This is to set aside Kant's question "What is man?" and to substitute the question "What sort of world can we prepare for our great grandchildren?"

He who intends to enjoy life should not be busy about many things, and in what he does should not undertake what exceeds his natural capacity. On the contrary, he should have himself so in hand that even when fortune comes his way, and is apparently ready to lead him on to higher things, he should put her aside and not o'erreach his powers. For a being of moderate size is safer than one that bulks too big.

As long as you live, keep learning how to live.

I am convinced we do not only love ourselves in others but hate ourselves in others too.

But we, O blockhead, with dogged spite and armored loveshall force those deaf dark powers to grow ears and hear us!I know that God is earless, eyeless, and heartless too,a brainless Dragon Worm that crawls on earth and hopesin anguish and then in secret that we'll give him soul,for then he, too, may sprout ears, eyes, to match his growth,but God is clay in my ten fingers, and I mould him!

The motto should not be: Forgive one another; rather, Understand one another.

Dreams, as we all know, are very queer things: some parts are presented with appalling vividness, with details worked up with the elaborate finish of jewellery, while others one gallops through, as it were, without noticing them at all, as, for instance, through space and time. Dreams seem to be spurred on not by reason but by desire, not by the head but by the heart, and yet what complicated tricks my reason has played sometimes in dreams, what utterly incomprehensible things happen to it!

What am I, other than a chance in the infinite probabilities of not having been!

When alterations in technical terms become necessary, it is desirable that the new term should contain in its form some memorial of the old one.

It is love that leniently and mercifully says: I forgive you everything-if you are forgiven only little, then it is because you love only little. Justice severely sets the boundary and says: No further! This is the limit. For you there is no forgiveness, and there is nothing more to be said.

If there is anyone who owes everything to Bach, it is certainly God.

Of course I base my characters partly on the people I know-one can't escape it-but fictional characters are oversimplified; they're much less complex than the people one knows.

[I]t would be a piece of ingenuousness to accuse the man of to-day of his lack of moral code. The accusation would leave him cold, or rather, would flatter him. Immoralism has become a commonplace, and anybody and everybody boasts of practising it.

One must look into hell before one has any right to speak of heaven.

He that knows anything, knows this, in the first place, that he need not seek long for instances of his ignorance.

Audacity augments courage; hesitation, fear.

Earth is a ball that is over 12,000 kilometres in diameter, and if it were modelled into an object the size of a billiard ball, with all its surface unevenness reproduced exactly to scale, the model would be smoother than an ordinary billiard ball and the ocean would be an all but unnoticeable mist of dampness over 70 percent of its surface.

Even in those cities which seem to enjoy the blessings of peace, and where the arts florish, the inhabitants are devoured by envy, cares and anxieties, which are greater plagues than any experienced in a town when it is under siege.

Not a May-game is this man's life; but a battle and a march, a warfare with principalities and powers. No idle promenade through fragrant orange-groves and green flowery spaces, waited on by the choral Muses and the rosy Hours: it is a stern pilgrimage through burning sandy solitudes, through regions of thick-ribbed ice. He walks among men; loves men, with inexpressible soft pity,-as they cannot love him: but his soul dwells in solitude, in the uttermost parts of Creation. In green oases by the palm-tree wells, he rests a space; but anon he has to journey forward, escorted by the Terrors and the Splendours, the Archdemons and Archangels. All Heaven, all Pandemonium are his escort. The stars keen-glancing, from the Immensities, send tidings to him; the graves, silent with their dead, from the Eternities. Deep calls for him unto Deep.

We say in popular speech that we come into this world, but we do nothing of the kind. We come out of it. In the same way as the fruit comes out of the tree, the egg from the chicken, and the baby from the womb, we are symptomatic of the universe. Just as in the retina there are myriads of little nerve endings, we are the nerve endings of the universe.

We do not go to cowards for tender dealing; there is nothing so cruel as panic; the man who has least fear for his own carcase, has most time to consider others.

The absolute idea is the subject in its final form, thought. The otherness and negation is the object, being. The absolute idea now has to be interpreted as objective being. Hegel's Logic thus ends where it began, with the category of being. This, however is a different being that can no longer be explained thought he concepts applied in the analysis that opened the Logic. For being now is understood in its notion that is, as a concrete totality wherein all particular forms subsist as the essential distinctions and relations of on comprehensive principle. Thus comprehended, being is nature, and dialectical thought passes on to the Philosophy of Nature.

We live together, we act on, and react to, one another; but always and in all circumstances we are by ourselves. The martyrs go hand in hand into the arena; they are crucified alone. Embraced, the lovers desperately try to fuse their insulated ecstasies into a single self-transcendence; in vain. By its very nature every embodied spirit is doomed to suffer and enjoy in solitude. Sensations, feelings, insights, fancies - all these are private and, except through symbols and at second hand, incommunicable. We can pool information about experiences, but never the experiences themselves. From family to nation, every human group is a society of island universes.

'Tis a grievous thing to be subject to an inferior.

O ye of little faith, why reason ye among yourselves, because ye have brought no bread? Do ye not yet understand, neither remember the five loaves of the five thousand, and how many baskets ye took up? Neither the seven loaves of the four thousand, and how many baskets ye took up? How is it that ye do not understand that I spake it not to you concerning bread, that ye should beware of the leaven of the Pharisees and of the Sadducees?

If we sit and talk in a dark room, words suddenly acquire new meanings and different textures...and on the radio. Given only the sound of a play, we have to fill in all of the senses, not just the sight of the action. So much do-it-yourself, or completion and "closure" of action, develops a kind of independent isolation in the young that makes them remote and inaccessible.

It is a greatness not of mere body and gigantic bulk, but a rude greatness of soul. There is a sublime uncomplaining melancholy traceable in these old hearts. A great free glance into the very deeps of thought. They seem to have seen, these brave old Northmen, what Meditation has taught all men in all ages, That this world is after all but a show,-a phenomenon or appearance, no real thing. All deep souls see into that,-the Hindoo Mythologist, the German Philosopher,-the Shakspeare, the earnest Thinker, wherever he may be.

To choose this or that is to affirm at the same time the value of what we choose, because we can never choose evil. We always choose the good, and nothing can be good for us without being good for all.

The assumption of a Final Cause in the structure of each part of animals and plants is as inevitable as the assumption of an Efficient Cause for every event. The maxim that in organized bodies nothing is 'in vain', is as necessarily true as the maxim that nothing happens 'by chance'.

The African [slave] trade was, in his opinion, an absolute robbery. It therefore could not be a doubt with the House, whether it was proper to abolish it.

Both in England and on the Continent a graduated property tax (l'impôt progressif) has been advocated, on the avowed ground that the state should use the instrument of taxation as a means of mitigating the inequalities of wealth. I am as desirous as any one that means should be taken to diminish those inequalities, but not so as to relieve the prodigal at the expense of the prudent.To tax the larger incomes at a higher percentage than the smaller is to lay a tax on industry and economy; to impose a penalty on people for having worked harder and saved more than their neighbours. It is not the fortunes which are earned, but those which are unearned, that it is for the public good to place under limitation.

Eternity, not as a static "now," nor as a sequence of "nows" rolling off into the infinite, but as the "now" that bends back into itself. ... Thinking the most difficult thought of philosophy means thinking being as time.

What does not exist must be something, or it would be meaningless to deny its existence; and hence we need the concept of being, as that which belongs even to the non-existent.

Not much younger than these (sc. Hermotimus of Colophon and Philippus of Mende) is Euclid, who put together the Elements, collecting many of Eudoxus' theorems, perfecting many of Theaetetus', and also bringing to irrefragable demonstration the things which were only somewhat loosely proved by his predecessors. This man lived in the time of the first Ptolemy. For Archimedes, who came immediately after the first (Ptolemy), makes mention of Euclid: and, further, they say that Ptolemy once asked him if there was in geometry any shorter way than that of the elements, and he answered that there was no royal road to geometry. He is then younger than pupils of Plato but older than Eratosthenes and Archimedes; for the latter were contemporary with one another, as Eratosthenes somewhere says.

I have no hesitation in saying that although the American woman never leaves her domestic sphere and is in some respects very dependent within it, nowhere does she enjoy a higher station. And if anyone asks me what I think the chief cause of the extraordinary prosperity and growing power of this nation, I should answer that it is due to the superiority of their women.

False and doubtful positions, relied upon as unquestionable maxims, keep those who build on them in the dark from truth. Such are usually the prejudices imbibed from education, party, reverence, fashion, interest, et cetera.

Neither of us cares a straw for popularity. A proof of this is for example, that, because of aversion to any personality cult, I have never permitted the numerous expressions of appreciation from various countries with which I was pestered during the existence of the International to reach the realm of publicity, and have never answered them, except occasionally by a rebuke. When Engels and I first joined the secret Communist Society we made it a condition that everything tending to encourage superstitious belief in authority was to be removed from the statutes.
