Death poses a problem which replaces all the others. What is deadly to philosophy, to the naive belief in the hierarchy of perplexities.

The spirits that I summoned up, I now can't rid myself of.

At least two thirds of our miseries spring from human stupidity, human malice, and those great motivators and justifiers of malice and stupidity, idealism, dogmatism and proselytizing zeal on behalf of religious or political idols.

Intelligence is quickness to apprehend as distinct from ability, which is capacity to act wisely on the thing apprehended.

It is not religion but revolution which is the opium of the people.

The more the concept of reason becomes emasculated, the more easily it lends itself to ideological manipulation and to propagation of even the most blatant lies. ... Subjective reason conforms to anything.

I believe that man is in the last resort so free a being that his right to be what he believes himself to be cannot be contested.

So dazzling was the spread of constellations that it had the impact of a vision, of some hidden insight. I drove home saying to myself: The dead, too, are like this, blazing within us - invisibly.

The Religion that is afraid of science dishonours God and commits suicide. It acknowledges that it is not equal to the whole of truth, that it legislates, tyrannizes over a village of God's empires but is not the immutable universal law. Every influx of atheism, of skepticism is thus made useful as a mercury pill assaulting and removing a diseased religion and making way for truth.

In Mohammedanism the narrow principle of the Jews is expanded into universality and thereby overcome. Here, God is no longer, as in the Far East, regarded as existent in an immediately sensory way but is conceived as the one infinite power elevated above all the multiplicity of the world. Mohammedanism is, therefore, in the strictest sense of the word, the religion of sublimity.

A jealous lover of human liberty, deeming it the absolute condition of all that we admire and respect in humanity, I reverse the phrase of Voltaire, and say that, if God really existed, it would be necessary to abolish him. Ch. II; Variants or variant translations of this statement have also been attributed to Bakunin: The first revolt is against the supreme tyranny of theology, of the phantom of God. As long as we have a master in heaven, we will be slaves on earth. A boss in Heaven is the best excuse for a boss on earth, therefore If God did exist, he would have to be abolished.

It is the nature of all greatness not to be exact.

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.

Of all the books I have ever worked on, I think Asimov's Guide to Shakespeare gave me the most pleasure, day in, day out. For months and months I lived and thought Shakespeare, and I don't see how there can be any greater pleasure in the world, any pleasure, that is, that one can indulge in for as much as ten hours without pause, day after day indefinitely.

Friendship ... flourishes not so much by kindnesses as by sincerity.

Nothing could be more natural than the developement of the passions, nor more striking than the views of the human heart. What delicate struggles! and uncommonly pretty turns of thought!

A proposition is completely logically analyzed if its grammar is made completely clear: no matter what idiom it may be written or expressed in...

Armies are necessary, before all things, for the defense of governments from their own oppressed and enslaved subjects.

You take souls for vegetables.... The gardener can decide what will become of his carrots but no one can choose the good of others for them.

Forgetting when God does it in relation to sin, is the opposite of creating, since to create is to bring forth from nothing and to forget is to take back into nothing. What is hidden from my eyes, that I have never seen; but what is hidden behind my back, that I have seen. The one who loves forgives in this way; he forgives, he forgets, he blots out the sin, in love he turns toward the one he forgives; but when he turns toward him, he of course, cannot see what is lying behind his back.

Single-mindedness is all very well in cows or baboons; in an animal claiming to belong to the same species as Shakespeare it is simply disgraceful.

No nation keeps its word. A nation is a big, blind worm, following what? Fate perhaps. A nation has no honour, it has no word to keep. ... Hitler is himself the nation. That incidentally is why Hitler always has to talk so loud, even in private conversation - because he is speaking with 78 million voices.

The more remote and unreal the personal mother is, the more deeply will the son's yearning for her clutch at his soul, awakening that primordial and eternal image of the mother for whose sake everything that embraces, protects, nourishes, and helps assumes maternal form, from the Alma Mater of the university to the personification of cities, countries, sciences and ideals.

Thought is all light, and publishes itself to the universe. It will speak, though you were dumb, by its own miraculous organ. It will flow out of your actions, your manners, and your face. It will bring you friendships. It will impledge you to truth by the love and expectation of generous minds. By virtue of the laws of that Nature, which is one and perfect, it shall yield every sincere good that is in the soul, to the scholar beloved of earth and heaven.

Work at these things, practice them, these are the things you ought to desire; they are what will put you on the path of divine virtue - yes, by the one who entrusted our soul with the tetraktys, source of ever-flowing nature. Pray to the gods for success and get to work.

This aristocratic thesis is... the demos, the people, are the most numerous... also comprised of the most ordinary, and... even the worst, citizens. Therefore... what is best for the demos cannot be what is best for the polis... the city.

Whenever you say anything good about East Germany, immediately somebody jumps up and says, "My God, you're a Stalinist..." I'm not defending everything about it, of course. But I laboured on the chapter that talks about the east. I fact-checked it; I had somebody else fact-check it. I knew that I was going to get a lot of flak for that. But in the beginning, East Germany did a better job. They just did.

Even a minor event in the life of a child is an event of that child's world and thus a world event.

Disease of the home and of the life comes about in the same way as that of the body.

Implication is thus the very texture of our web of belief, and logic is the theory that traces it.

Faith is a living, bold trust in God's grace, so certain of God's favor that it would risk death a thousand times trusting in it. Such confidence and knowledge of God's grace makes you happy, joyful and bold in your relationship to God and all creatures. The Holy Spirit makes this happen through faith. Because of it, you freely, willingly and joyfully do good to everyone, serve everyone, suffer all kinds of things, love and praise the God who has shown you such grace.

Man, if he is to remain man, must advance by way of consciousness. There is no road leading backward. ... We can no longer veil reality from ourselves by renouncing self-consciousness without simultaneously excluding ourselves from the historical course of human existence.

What right have humans to impose our values on members of another race or species? The charge is seductive but misplaced. There is no anthropomorphism here, no imposition of human values on alien minds. Human and nonhuman animals are alike in an ethically critical respect. The pleasure-pain axis is universal to sentient life. No sentient being wants to be harmed - to be asphyxiated, dismembered, or eaten alive. The wishes of a terrified toddler or a fleeing zebra to flourish unmolested are not open to doubt even in the absence of the verbal capacity to say so.

By God's grace, I know Satan very well. If Satan can turn God's Word upside down and pervert the Scriptures, what will he do with my words -- or the words of others?

One good schoolmaster is of more use than a hundred priests.

He who does not realize to what extent shifting fortune and necessity hold in subjection every human spirit, cannot regard as fellow-creatures nor love as he loves himself those whom chance separated from him by an abyss. The variety of constraints pressing upon man give rise to the illusion of several distinct species that cannot communicate.

As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power. You can think about only what you know, so you ought to learn something; on the other hand, you can know only what you have thought about.

We must not always judge of the generality of the opinion by the noise of the acclamation.

Few men have been admired by their own domestics.

Abbot Terrasson tells us that if the size of a book were measured not by the number of its pages but by the time required to understand it, then we could say about many books that they would be much shorter were they not so short.

The objects of a financier are, then, to secure an ample revenue; to impose it with judgment and equality; to employ it economically; and, when necessity obliges him to make use of credit, to secure its foundations in that instance, and for ever, by the clearness and candour of his proceedings, the exactness of his calculations, and the solidity of his funds.

I might try to save the view that 'future contingents' have no truth value by saying that even present-tense statements have no truth value if they refer to the outcome of events that are so far away that a causal signal informing me of the outcome could not have reached me-now without traveling faster than light. In other words, I might attempt saying that statements about events that are in neither the upper half nor the lower half of my light-cone have no truth value. In addition, statements about events in the upper half of my light-cone have no truth value, since they are in my future according to every coordinate system. So only statements about events in the lower half of my light-cone have a truth value; only events that are in 'my past* according to all observers are determined.

What has philosophy got to do with measuring anything? It's the mathematicians you have to trust, and they measure the skies like we measure a field.

The laws of Rome had wisely divided public power among a large number of magistracies, which supported, checked and tempered each other. Since they all had only limited power, every citizen was qualified for them, and the people - seeing many persons pass before them one after the other - did not grow accustomed to any in particular. But in these times the system of the republic changed. Through the people the most powerful men gave themselves extraordinary commissions - which destroyed the authority of the people and magistrates, and placed all great matters in the hands of one man, or a few.

Historical time knows no lasting present.

The farther men get from God, the farther they advance into the knowledge of religions.

Because machines could be made progressively more and more efficient, Western man came to believe that men and societies would automatically register a corresponding moral and spiritual improvement. Attention and allegiance came to be paid, not to Eternity, but to the Utopian future. External circumstances came to be regarded as more important than states of mind about external circumstances, and the end of human life was held to be action, with contemplation as a means to that end. These false and historically, aberrant and heretical doctrines are now systematically taught in our schools and repeated, day in, day out, by those anonymous writers of advertising copy who, more than any other teachers, provide European and American adults with their current philosophy of life. And so effective has been the propaganda that even professing Christians accept the heresy unquestioningly and are quite unconscious of its complete incompatibility with their own or anybody else's religion.
