There never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.

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

A definition may be very exact, and yet go but a very little way towards informing us of the nature of the thing defined.

There ought to be some regulation with respect to the spirit of denunciation that now prevails. If every individual is to indulge his private malignancy or his private ambition, to denounce at random and without any kind of proof, all confidence will be undermined and all authority be destroyed. Calumny is a species of treachery that ought to be punished as well as any other kind of treachery. It is a private vice productive of public evils; because it is possible to irritate men into disaffection by continual calumny who never intended to be disaffected. It is therefore equally as necessary to guard against the evils of unfounded or malignant suspicion as against the evils of blind confidence. It is equally as necessary to protect the characters of public officers from calumny as it is to punish them for treachery or misconduct.

From fanaticism to barbarism is only one step.

To enrich God, man must become poor; that God may be all, man must be nothing.

Ideas, cultures, and histories cannot seriously be understood or studied without their force, or more precisely their configurations of power, also being studied.

Wherever ideas come together they tend to weld into general ideas; and whenever they are generally connected, general ideas govern the connection; and these general ideas are living feelings spread out.

He who would write heroic poems should make his whole life a heroic poem.

Your pride has been too much for the pride of your admirers; they were numerous and high-spirited, but they have all run away, overpowered by your superior force of character; not one of them remains. And I want you to understand the reason why you have been too much for them. You think that you have no need of them or of any other man, for you have great possessions and lack nothing, beginning with the body, and ending with the soul. Socrates speaking to Alcibiades

The election... on November 3 ... illustrates a lot of these clashing forces. ..That election was the most important political fight ...in my lifetime. It's important not just for the United States but... for the rest of the world, given the role that the United States has historically played in maintaining that broader liberal international order.

Amongst so many borrowed things, I am glad if I can steal one, disguising and altering it for some new service.

Even the most inspired verse, which boasts not without a relative justification to be immortal, becomes in the course of ages a scarcely legible hieroglyphic; the language it was written in dies, a learned education and an imaginative effort are requisite to catch even a vestige of its original force. Nothing is so irrevocable as mind.

Whatever the poverty of our knowledge in this respect, it is certain that the question of the sign is itself more or less, or in any event something other, than a sign of the times. To dream of reducing it to a sign of the times is to dream of violence.

We know as little of a supreme being as of Matter. But there is as little doubt of the existence of a supreme being as of Matter. The world beyond is reality, and experiential fact. We only don't understand it.

[H]uman nature as encoded in our DNA isn't immutable. Mankind's barbaric track-record to date is an unreliable guide to the future. If Homo sapiens' nastier alleles and their more sinister combinations can be silenced or edited out of the genome, and new improved code-sequences inserted instead, then the pessimists will be confounded. A major discontinuity in the development of life lies ahead. Providentially, we've learned that the DNA-driven world isn't written in God-given proprietary code it would be hubris to tamper with, but in bug-ridden open source amenable to improvement.

"I should prefer that Fortune keep me in her camp rather than in the lap of luxury. If I am tortured, but bear it bravely, all is well; if I die, but die bravely, it is also well."

It is not proper either to have a blunt sword or to use freedom of speech ineffectually. Neither is the sun to be taken from the world, nor freedom of speech from erudition.

Never stay up on the barren heights of cleverness, but come down into the green valleys of silliness.

Again, Amyclas the Heracleotean, one of Plato's familiars, and Menæchmus, the disciple, indeed, of Eudoxus, but conversant with Plato, and his brother Dinostratus, rendered the whole of geometry as yet more perfect. But Theudius, the Magnian, appears to have excelled, as well in mathematical disciplines, as in the rest of philosophy. For he constructed elements egregiously, and rendered many particulars more universal. Besides, Cyzicinus the Athenian, flourished at the same period, and became illustrious in other mathematical disciplines, but especially in geometry. These, therefore, resorted by turns to the Academy, and employed themselves in proposing common questions.

Darwinism is not a testable scientific theory, but a metaphysical research program. Unsourced variant: Evolution is not a fact. Evolution doesn't even qualify as a theory or as a hypothesis. It is a metaphysical research program, and it is not really testable science.

Emotion is the chief source of all becoming-conscious. There can be no transforming of darkness into light and of apathy into movement without emotion.

The vicious circle of dread of war which leads the nations to arm themselves for self-protection, with the result that bloated armaments ultimately lead to the war which they were intended to avert, can be broken in either of two conceivable ways. There might arise a unique world power, brought into being by the unification of all those now in possession of weapons, and equipped with the capacity to forbid the lesser and unarmed nations to make war. On the other hand, it may arise by the working of a fate to us still inscrutable which, out of ruin, will disclose a way towards the development of a new human being. To will the discovery of this way would be blind impotence, but those who do not wish to deceive themselves will be prepared for the possibility.

Pleasure and distress, fear and courage, desire and aversion, where have these affections and experiences their seat? Clearly, either in the Soul alone, or in the Soul as employing the body, or in some third entity deriving from both. And for this third entity, again, there are two possible modes: it might be either a blend or a distinct form due to the blending.

Frazer's account of the magical and religious views of mankind is unsatisfactory; it makes these views look like errors.

Everyone is sure of this [that errors are normally distributed], Mr. Lippman told me one day, since the experimentalists believe that it is a mathematical theorem, and the mathematicians that it is an experimentally determined fact.

If you punish a child for being naughty, and reward him for being good, he will do right merely for the sake of the reward; and when he goes out into the world and finds that goodness is not always rewarded, nor wickedness always punished, he will grow into a man who only thinks about how he may get on in the world, and does right or wrong according as he finds either of advantage to himself.

Like rowers, who advance backward.

The republic is nothing whatever but - absolute monarchy; for it makes no difference whether the monarch is called prince or people, both being a 'majesty'.

"There is no God," cry the masses more and more vociferously; and with the loss of God man loses his sense of values - is, as it were, massacred because he feels himself of no account.

The best thing about the sciences is their philosophical ingredient, like life for an organic body. If one dephilosophizes the sciences, what remains left? Earth, air, and water.

Chinese script is not visual but iconic and tactile. It does not disturb the tribal bonds.

What is beginning to emerge, then, is a theory about psychic sensitivity. It runs as follows. When I relax deeply, it is as if someone opened up the partition between the two compartments of my brain, turning them into a single large room. I experience a sense of mental freedom as if I can suddenly breathe more deeply, and a feeling of contact with things. Everyone has had the experience of being in a state of hurry or excitement, and failing to notice that they have bruised or scratched themselves -- until the excitement evaporates and the pain makes itself known. Hurry and tension raise our sensitivity threshold, and at the same time, erect a glass wall between us and reality. In the "unicameral" state, this wall vanishes, and everything seems more real.

It doesn't matter that it can't last, that we don't find it more often. To know that there is such perfection, that there has been such perfection - it is worth living for. It exists. It has been - it is. One can contemplate it and feel complete peace.

My dear Kepler, what would you say of the learned here, who, replete with the pertinacity of the asp, have steadfastly refused to cast a glance through the telescope? What shall we make of this? Shall we laugh, or shall we cry?

One cannot become a saint when one works sixteen hours a day.

I have studied these things - you have not.

For some identify happiness with virtue, some with practical wisdom, others with a kind of philosophic wisdom, others with these, or one of these, accompanied by pleasure or not without pleasure; while others include also external prosperity. Now ... it is not probable that these should be entirely mistaken, but rather that they should be right in at least some one respect or even in most respects.

Would you not think him an utter fool who wept because he was not alive a thousand years ago? And is he not just as much of a fool who weeps because he will not be alive a thousand years from now? It is all the same; you will not be, and you were not. Neither of these periods of time belongs to you.

That the uneducated and the ill-educated should think the hypothesis that all races of beings, man inclusive, may in process of time have been evolved from the simplest monad, a ludicrous one, is not to be wondered at. But for the physiologist, who knows that every individual being is so evolved-who knows, further, that in their earliest condition the germs of all plants and animals whatever are so similar, "that there is no appreciable distinction amongst them, which would enable it to be determined whether a particular molecule is the germ of a Conferva or of an Oak, of a Zoophyte or of a Man";-for him to make a difficulty of the matter is inexcusable.

The "tragic flaw" is not a detail of characterization, a mere "fly in the ointment", but a structural feature of ordinary consciousness.

Man is forming thousands of ridiculous relations between himself and God.

It might otherwise appear paradoxical that money can be replaced by worthless paper; but that the slightest alloying of its metallic content depreciates it.

A subject interests me and holds my attention only so long as it presents me with difficulties, only so long as I am at odds with it and have, as it were, to struggle with it; but once I have mastered it I hurry on to something else, to a new subject; for my interest is not confined to any particular field or subject; it extends to everything human. This does not mean that I am an intellectual miser or egoist, who amasses knowledge for himself alone; by no means! What I do and think for myself, I must also think and do for others. But I feel the need of instructing others in a subject only so long as, while instructing others, I am also instructing myself.

Tyranny offers relief from the burden of sanity and a licence to enact forbidden impulses of hatred and violence. By acting on these impulses and releasing them in their subjects tyrants give people a kind of happiness, which as individuals they may be incapable of achieving.

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 the private dominion over things that condemns millions of people to be mere nonentities, living corpses without originality or power of initiative, human machines of flesh and blood, who pile up mountains of wealth for others and pay for it with a gray, dull and wretched existence for themselves. I believe that there can be no real wealth, social wealth, so long as it rests on human lives - young lives, old lives and lives in the making.

Animal Liberation is Human Liberation too.
