As the analysis of a substantial composite terminates only in a part which is not a whole, that is, in a simple part, so synthesis terminates only in a whole which is not a part, that is, the world.

We hardly know any instance of the strength and weakness of human nature so striking, and so grotesque, as the character of this haughty, vigilant, resolute, sagacious blue-stocking, half Mithridates and half Trissotin, bearing up against a world in arms, with an ounce of poison in one pocket and a quire of bad verses in the other.

[on Epicurus] His starting point is a conviction that apathy is impossible, and that pleasure - though not necessarily sensual pleasure - is the only conceivable, and quite legitimate, end of life and action. "Nature leads every organism to prefer its own good to every other good" - even the stoic finds a subtle pleasure in renunciation. "We must not avoid pleasures, but we must select them". Epicurus, then, is no epicurean, he exalts the joys of intellect rather than those of sense; he warns against pleasures that excite and disturb the soul which they should rather quite and appease. In the end he proposes to seek not pleasure in its usual sense, but ataraxia - tranquility, equaninimity, repose of mind; all of which trembles on the verge of Zeno's "Apathy"

When... in the course of all these thousands of years has man ever acted in accordance with his own interests?

Many things about our bodies would not seem to us so filthy and obscene if we did not have the idea of nobility in our heads.

There are people into whose heads it never enters to conceive of any better state of society than that which now exists.

The whole life of the upper classes is a constant inconsistency. The more delicate a man's conscience is, the more painful this contradiction is to him.

The coming of Buddhism to the West may well prove to be the most important event of the Twentieth Century.

The music that can deepest reach, And cure all ill, is cordial speech.

The only interesting philosophers are the ones who have stopped thinking and have begun to search for happiness.

Everyday we act in ways that reflect our ethical judgements.

I regard Peter as one of the great moralists, because I suspect that more than anyone he has helped to change the attitudes of very many people to the sufferings of animals. Peter is a utilitarian in normative ethics, and a humane attitude to animals is a natural corollary of utilitarianism. Utilitarian concern for animals goes back to Bentham, who, presumably alluding to the Kantians, said that the question was not whether animals can reason, but whether they can suffer.

A new development began for relativity theory after 1925 with its absorption into quantum physics. The first great success was scored by Dirac's quantum mechanical equations of the electron, which introduced a new sort of quantities, the spinors, besides the vectors and tensors into our physical theories. ...But difficulties of the gravest kind turned up when one passed from one electron or photon to the interaction among an indeterminate number of such particles. In spite of several advances a final solution of this problem is not yet in sight and may well require a deep modification of the foundation of quantum mechanics, such as would account in the same basic manner for the elementary electric charge e as relativity theory and our present quantum mechanics account for c and h.

The kingdom of heaven can be compared to a king who wanted to settle accounts with his slaves.

Just as the witticism brings two very different real objects under one concept, the pun brings two different concepts, by the assistance of accident, under one word.

The destructive work of totalitarian machinery, whether or not this word is used, is usually supported by a special kind of primitive social philosophy. It proclaims not only that the common good of 'society' has priority over the interests of individuals, but that the very existence of individuals as persons is reducible to the existence of the social 'whole'; in other words, personal existence is, in a strange sense, unreal. This is a convenient foundation for any ideology of slavery.

Only charity admitteth no excess. For so we see, aspiring to be like God in power, the angels transgressed and fell.

We cannot understand what happens in the universe. What is glorious in it is united with what is full of horror. What is full of meaning is united to what is senseless. The spirit of the universe is at once creative and destructive - it creates while it destroys and destroys while it creates, and therefore it remains to us a riddle. And we must inevitably resign ourselves to this.

Adam came from great power and great wealth, but he was not worthy of you. For had he been worthy, [he would] not [have tasted] death.

And this is the vote which [Cato] casts concerning them both: "If Caesar wins, I slay myself; if Pompey, I go into exile." What was there for a man to fear who, whether in defeat or in victory, had assigned to himself a doom which might have been assigned to him by his enemies in their utmost rage? So he died by his own decision.

What is generally regarded as success - acquisition of wealth, the capture of power or social prestige - I consider the most dismal failures. I hold when it is said of a man that he has arrived, it means that he is finished - his development has stopped at that point. I have always striven to remain in a state of flux and continued growth, and not to petrify in a niche of self-satisfaction. If I had my life to live over again, like anyone else, I should wish to alter minor details. But in any of my more important actions and attitudes I would repeat my life as I have lived it. Certainly I should work for Anarchism with the same devotion and confidence in its ultimate triumph.

No particular experiences are linked with any particular statements in the interior of the field, except indirectly through considerations of equilibrium affecting the field as a whole.

I hope we shall... crush in it's birth the aristocracy of our monied corporations which dare already to challenge our government to a trial of strength and bid defiance to the laws of our country.

The beauty or uncomeliness of many things, in good and ill breeding, will be better learnt, and make deeper impressions on them, in the examples of others, than from any rules or instructions can be given about them.

A little river seems to him, who has never seen a larger river, a mighty stream; and so with other things-a tree, a man-anything appears greatest to him that never knew a greater.

My theory is that all women have hydrofluoric acid bottled up inside.

The dullness of fact is the mother of fiction.

Each of us believes, quite unconsciously of course, that we alone pursue the truth, which the rest are incapable of seeking out and unworthy of attaining. This madness is so deep-rooted and so useful that it is impossible to realize what would become of each of us if it were someday to disappear.

I have worked for this restlessness oriented toward inward deepening. But without authority. Instead of conceitedly making myself out to be a witness for the truth and causing others rashly to want to be the same, I am an unauthorized poet who influences by means of the ideas.

A good man with a good conscience doesn't walk so fast.

Octavia lost Marcellus, whom both his father-in-law and his uncle had begun to depend upon, and to place upon his shoulders the weight of the empire - a young man of keen intelligence and firm character, frugal and moderate in his desires to an extent which deserved especial admiration in one so young and so wealthy, strong to endure labour, averse to indulgence, and able to bear whatever burden his uncle might choose to lay, or I may say to pile upon his shoulders. Augustus had well chosen him as a foundation, for he would not have given way under any weight, however excessive.

France had endeavoured under the specious pretext of an enlarged benevolence, to sow the seeds of enmity among nations, and destroy all local attachments, calling them narrow and illiberal-thereby to dissever the people from their governors.

I must confess that my estimate of Lovecraft would not have pleased his most ardent admirers. The view I expressed in that book was that, while Lovecraft was distinctly a creative genius in his own way, his pessimism should not be taken too seriously; that it was the pessimism of a sick recluse, and had about it an element of rassentiment, a kind of desire to take revenge on the world that rejected him. In short, Lovecraft was a 19th century romantic, born in the wrong time. Most men of genius dislike their own age, but the really great ones impose their own vision on the age. The weak ones turn away into a world of gloomy fantasy.

Are not five sparrows sold for two farthings, and not one of them is forgotten before God? But even the very hairs of your head are all numbered. Fear not therefore: ye are of more value than many sparrows.

If you say to someone who has ears to hear: "What you are doing to me is not just," you may touch and awaken at its source the spirit of attention and love. But it is not the same with words like, "I have the right..." or "you have no right to..." They evoke a latent war and awaken the spirit of contention.

He [the child] does not despise real woods because he has read of enchanted woods: the reading makes all real woods a little enchanted.

In art the best is good enough.

The rule, acknowledged or not, seems to be that if we have great power we must use it. We would use a steam shovel to pick up a dime. We have experts who can prove there is no other way to do it.

Penitence follows hasty decisions.

René Descartes is more widely known as a philosopher than as a mathematician, although his philosophy has been controverted while his mathematics has not. ...In accordance with the ideals of his age, when experimental science was first seriously challenging arrogant speculation, Descartes set a greater store by his philosophy than his mathematics. But he fully appreciated the power of his new method in geometry.

As far as men go, it is not what they are that interests me, but what they can become.

The distance between oneself and other persons and other species can fall anywhere on a continuum. Even for other persons the understanding of what it is like to be them is only partial, and when one moves to species very different from oneself, a lesser degree of partial understanding may still be available. The imagination is remarkably flexible. My point, however, is not that we cannot know what it is like to be a bat. I am not raising that epistemological problem. My point is rather that even to form a conception of what it is like to be a bat and a fortiori to know what it is like to be a bat, one must take up the bat's point of view.

The errors of Communism must be rectified; but there is no necessity for giving up the name, which is a simple assertion of the paramount importance of Social Feeling. However, now that we have happily passed from monarchy to republicanism, the name of Communist is no longer indispensable; the word Republican expresses the meaning as well, and without the same danger. Positivism, then, has nothing to fear from Communism; on the contrary, it will probably be accepted by most Communists among the working classes, especially in France where abstractions have but little influence on minds thoroughly emancipated from theology. The people will gradually find that the solution of the great social problem which Positivism offers is better than the Communistic solution.

It is very likely that there are many, many planets carrying life, even intelligent life, throughout the universe, because there are so many stars. By sheer chance, even if those chances are small, a great many life forms and a great many intelligences may exist.

You can choose whatever name you like for the two types of government. I personally call the type of government which can be removed without violence "democracy", and the other "tyranny".

The man with the clear head is the man who frees himself from those fantastic "ideas" and looks life in the face, realises that everything in it is problematic, and feels himself lost. As this is the simple truth - that to live is to feel oneself lost - he who accepts it has already begun to find himself, to be on firm ground. Instinctively, as do the shipwrecked, he will look round for something to which to cling, and that tragic, ruthless glance, absolutely sincere, because it is a question of his salvation, will cause him to bring order into the chaos of his life.
