It is the courage to make a clean breast of it in the face of every question that distinguishes the philosopher. He must be like Sophocles' Oedipus, who, seeking enlightenment concerning his terrible fate, pursues his indefatigable inquiry even though he divines that appalling horror awaits him in the answer. But most of us carry with us the Jocasta in our hearts, who begs Oedipus, for God's sake, not to inquire further.

It is by the Imperial Capital that contemporaries (and posterity, too) judge an Empire, and its magnificence impresses them mightily and leads them to judge the Emperor a great man and hero, even though it may all be based on robbery, and though the provinces of the Empire may be sunk in misery.

Let great authors have their due, as time, which is the author of authors, be not deprived of his due, which is, further and further to discover truth.

A great deal of intelligence can be invested in ignorance when the need for illusion is deep. 

It is a great good fortune, as Stendhal said, for one "to have his passion as a profession."

It has been observed that missiles and projectiles describe a curved path of some sort; however no one has pointed out the fact that this path is a parabola. But this and other facts, not few in number or less worth knowing, I have succeeded in proving; and what I consider more important, there have been opened up to this vast and most excellent science, of which my work is merely the beginning, ways and means by which other minds more acute than mine will explore its remote corners.

...all of the philosophers put together are not worth a single saint.

If you reject absolutely any single sensation without stopping to discriminate with respect to that which awaits confirmation between matter of opinion and that which is already present, whether in sensation or in feelings or in any immediate perception of the mind, you will throw into confusion even the rest of your sensations by your groundless belief and so you will be rejecting the standard of truth altogether. If in your ideas based upon opinion you hastily affirm as true all that awaits confirmation as well as that which does not, you will not escape error, as you will be maintaining complete ambiguity whenever it is a case of judging between right and wrong opinion.

We are observing ourselves being observed by the painter, and made visible to his eyes by the same light that enables us to see him. And just as we are about to apprehend ourselves, transcribed by his hand as though in a mirror, we find that we can in fact apprehend nothing of that mirror but its lusterless back. The other side of a psyche.

There is no moral precept that does not have something inconvenient about it.

Wit is the appearance, the external flash of imagination. Thus its divinity, and the witty character of mysticism.

What, by a word lacking even in grammar, is called amorality, is a thing that does not exist. If you are unwilling to submit to any norm, you have, nolens volens, to submit to the norm of denying all morality, and this is not amoral, but immoral. It is a negative morality which preserves the empty form of the other.

Truth and clarity are complementary.

Thou shouldst not become presumptuous through great connections and race; for in the end thy trust is on thine own deeds.

There is but One Principle that proceeds from God; and thus, in consequence of the unity of the Power, it is possible for each Individual to schematise his World of Sense in accordance with the law of that original harmony; - and every Individual, under the condition of being found on the way towards the recognition of the Imperative, must so schematise it. I might say: - Every Individual can and must, under the given condition, construct the True World of Sense, - for this indeed has beyond the universal and formal laws above deduced, no other Truth and Reality than this universal harmony.

Look upon men and pity them. Look at yourself amid all men and pity yourself. In the obscure dusk of life we touch and fumble at each other, we ask questions, we listen, we shout for help.

Let no man be ashamed to speak what he is not ashamed to think.

Thought depends largely on the stomach. In spite of this, those with the best stomachs are not always the best thinkers.

One of the major problems of our society is that so many people are too intelligent to accept religion, but not intelligent or strong-minded enough to look for acceptable alternatives; in the same way, many people are strong-minded enough not to want to be 'organization men', but incapable of seeing beyond an act of protest. These situations produce a sense of being 'between two stools', lacking real motive; a sense of mental strain is produced that may find its outlet in violence, or in organised anti-social behaviour.

The same energy of character which renders a man a daring villain would have rendered him useful to society, had that society been well organized.

He who helps the guilty, shares the crime.

There are certain occupations, even in modern society, which entail living in isolation and do not require great physical or intellectual effort. Such occupations as the service of lighthouses and lightships come to mind. Would it not be possible to place young people who wish to think about scientific problems, especially of a mathematical or philosophical nature, in such occupations? Very few young people with such ambitions have, even during the most productive period of their lives, the opportunity to devote themselves undisturbed for any length of time to problems of a scientific nature.

Mercy to the guilty is cruelty to the innocent.

Russia was a slave in Europe but would be a master in Asia.

Everyone is entitled to commit murder in the imagination once in a while, not to mention lesser infractions.

One may be humble out of pride.

Feuerbach ... recognizes ... "even love, in itself the truest, most inward sentiment, becomes an obscure, illusory one through religiousness, since religious love loves man only for God's sake, therefore loves man only apparently, but in truth God only." Is this different with moral love? Does it love the man, this man for this man's sake, or for morality's sake, for Man's sake, and so-for homo homini Deus-for God's sake?

Every step closer to my soul excites the scornful laughter of my devils, those cowardly ear-whisperers and poison-mixers. It was easy for them to laugh, since I had to do strange things.

When the ricochets of atomic billiards chance to put together an object that has a certain, seemingly innocent property, something momentous happens in the universe. That property is an ability to self-replicate; that is, the object is able to use the surrounding materials to make exact copies of itself, including replicas of such minor flaws in copying as may occasionally arise. What will follow from this singular occurrence, anywhere in the universe, is Darwinian selection and hence the baroque extravaganza that, on this planet, we call life. Never were so many facts explained by so few assumptions. Not only does the Darwinian theory command superabundant power to explain. Its economy in doing so has a sinewy elegance, a poetic beauty that outclasses even the most haunting of the world's origin myths. 

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.

Mucius put his hand into the fire. It is painful to be burned; but how much more painful to inflict such suffering upon oneself!

One common strategy on which we should all be able to agree is to take steps to reduce the risk of human extinction when those steps are also highly effective in benefiting existing sentient beings. For example, eliminating or decreasing the consumption of animal products will benefit animals, reduce greenhouse gas emissions, and lessen the chances of a pandemic resulting from a virus evolving among the animals crowded into today's factory farms, which are an ideal breeding ground for viruses. That therefore looks like a high-priority strategy.

The Managers of that Trade themselves, and others, testify, that many of these African nations inhabit fertile countries, are industrious farmers, enjoy plenty, and lived quietly, averse to war, before the Europeans debauched them with liquors, and bribing them against one another; and that these inoffensive people are brought into slavery, by stealing them, tempting Kings to sell subjects, which they can have no right to do, and hiring one tribe to war against another, in order to catch prisoners. By such wicked and inhuman ways the English are said to enslave towards one hundred thousand yearly; of which thirty thousand are supposed to die by barbarous treatment in the first year; besides all that are slain in the unnatural wars excited to take them. So much innocent blood have the Managers and Supporters of this inhuman Trade to answer for to the common Lord of all!

Men go to a fire for entertainment. When I see how eagerly men will run to a fire, whether in warm or in cold weather, by day or by night, dragging an engine at their heels, I'm astonished to perceive how good a purpose the level of excitement is made to serve.

I sit astride life like a bad rider on a horse. I only owe it to the horse's good nature that I am not thrown off at this very moment.

The three great elements of modern civilization, gunpowder, printing, and the Protestant religion.

Religion...is a man's total reaction upon life.

I pray you, magnificent Sir, do not trouble yourself to return to us, but await our coming to you.

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.

The Leninist agrarian reform has created a new and powerful layer of popular enemies of socialism on the countryside, enemies whose resistance will be much more dangerous and stubborn than that of the noble large landowners.

If you are distressed by anything external, the pain is not due to the thing itself, but to your estimate of it; and this you have the power to revoke at any moment.

It was his peculiar doctrine that a man has a perfect right to interfere by force with the slaveholder, in order to rescue the slave. I agree with him. They who are continually shocked by slavery have some right to be shocked by the violent death of the slaveholder, but no others.

Liberalism has merely cleared a field in which every soul and every corporate interest may fight with every other for domination. Whoever is victorious in this struggle will make an end of liberalism; and the new order, which will deem itself saved, will have to defend itself in the following age against a new crop of rebels.

My sympathies are, of course, with the Government side, especially the Anarchists; for Anarchism seems to me more likely to lead to desirable social change than highly centralized, dictatorial Communism.

Law and arbitrary power are in eternal enmity. Name me a magistrate, and I will name property; name me power, and I will name protection. It is a contradiction in terms, it is blasphemy in religion, it is wickedness in politics, to say that any man can have arbitrary power. In every patent of office the duty is included. For what else does a magistrate exist? To suppose for power is an absurdity in idea. Judges are guided and governed by the eternal laws of justice, to which we are all subject. We may bite our chains, if we will, but we shall be made to know ourselves, and be taught that man is born to be governed by law; and he that will substitute will in the place of it is an enemy to God.

We suffer: the external world begins to exist . . . ; we suffer to excess: it vanishes. Pain instigates the world only to unmask its unreality.
