All metaphysical theories are inconclusively vulnerable to positivist attack.

At one level, this movement on behalf of oppressed farm animals is emotional...Yet the movement is also the product of a deep intellectual ferment pioneered by the Princeton scholar Peter Singer...This idea popularized by Professor Singer - that we have ethical obligations that transcend our species - is one whose time appears to have come...What we're seeing now is an interesting moral moment: a grass-roots effort by members of one species to promote the welfare of others...animal rights are now firmly on the mainstream ethical agenda.

Train any population rationally, and they will be rational. Furnish honest and useful employments to those so trained, and such employments they will greatly prefer to dishonest or injurious occupations. It is beyond all calculation the interest of every government to provide that training and that employment; and to provide both is easily practicable.

Men do not sufficiently realise that their future is in their own hands. Theirs is the task of determining first of all whether they want to go on living or not. Theirs is the responsibility, then, for deciding if they want merely to live, or intend to make just the extra effort required for fulfilling, even on their refractory planet, the essential function of the universe, which is a machine for the making of gods.

The sadistic person is as dependent on the submissive person as the latter is on the former; neither can live without the other. The difference is only that the sadistic person commands, exploits, hurts, humiliates, and that the masochistic person is commanded, exploited, hurt, humiliated. This is a considerable difference in a realistic sense; in a deeper emotional sense, the difference is not so great as that which they both have in common: fusion without integrity.

There is a greatness in the lives of those who build up religious systems, a greatness in action, in idea and in self-subordination, embodied in instance after instance through centuries of growth. There is a greatness in the rebels who destroy such systems: they are the Titans who storm heaven, armed with passionate sincerity. It may be that the revolt is the mere assertion by youth of its right to its proper brilliance, to that final good of immediate joy. Philosophy may not neglect the multifariousness of the world - the fairies dance, and Christ is nailed to the cross.

A reproach can only hurt if it hits the mark. Whoever knows that he does not deserve a reproach can treat it with contempt.

The weapon of the Republic is terror, and virtue is its strength.

Do not judge according to appearance, but judge with righteous judgment.

National loyalty is founded in the love of place, of the customs and traditions that have been inscribed in the landscape and of the desire to protect these good things through a common law and a common loyalty.

Facing a landscape annihilated by the light, to remain serene supposes a temper I do not have. The sun is my purveyor of black thoughts; and summer the season when I have always reconsidered my relations with this world and with myself, to the greatest prejudice of both.

Much can be inferred about a man from his mistress: in her one beholds his weaknesses and his dreams.

But what is liberty without wisdom, and without virtue? It is the greatest of all possible evils; for it is folly, vice, and madness, without tuition or restraint.

If our Bodily Life is a burning, our Spiritual Life is a being burnt, a Combustion (or, is precisely the inverse the case?); Death, therefore, perhaps a Change of Capacity.

It is impossible that evils should be done away with, for there must always be something opposed to the good; and they must inevitably hover about mortal nature and this earth. Therefore we ought to try to escape from earth to the dwelling of the gods as quickly as we can; and to escape is to become like God, so far as this is possible, God is in no wise and in no manner unrighteous, but utterly and perfectly righteous, and there is nothing so like him as that one of us who in turn becomes most nearly perfect in righteousness.

The Prodigal Son at least walked home on his own feet. But who can duly adore that Love which will open the high gates to a prodigal who is brought in kicking, struggling, resentful, and darting his eyes in every direction for a chance of escape?

These preachers of beauty, which light the world with their admonishing smile.

..Whenever it ceases to be true that mankind, as a rule, prefer themselves to others, and those nearest to them to those more remote, from that moment Communism is not only practicable, but the only defensible form of society...

Evolution is a fact. Beyond reasonable doubt, beyond serious doubt, beyond sane, informed, intelligent doubt, beyond doubt evolution is a fact. The evidence for evolution is at least as strong as the evidence for the Holocaust, even allowing for eye witnesses to the Holocaust. It is the plain truth that we are cousins of chimpanzees, somewhat more distant cousins of monkeys, more distant cousins still of aardvarks and manatees, yet more distant cousins of bananas and turnips... continue the list as long as desired.

None but a coward dares to boast that he has never known fear.

Thought is as much a lie as love or faith.

Whatever you do, He will make good of it. But not the good He had prepared for you if you had obeyed him.

It was truly very good reason that we should be beholden to God only, and to the favour of his grace, for the truth of so noble a belief, since from his sole bounty we receive the fruit of immortality, which consists in the enjoyment of eternal beatitude.... The more we give and confess to owe and render to God, we do it with the greater Christianity.

Individual science fiction stories may seem as trivial as ever to the blinder critics and philosophers of today — but the core of science fiction, its essence, the concept around which it revolves, has become crucial to our salvation if we are to be saved at all.

At the speed of light there is no sequence; everything happens at the same instant.

Black women control the world. We are through being discriminated against.

The cravings of love and sex are met with absolute ignorance by the majority of parents, who consider it as something indecent and improper, something disgraceful, almost criminal, to be suppressed and fought like some terrible disease. The love and tender feelings in the young plant are turned into vulgarity and coarseness through the stupidity of those surrounding it, so that everything fine and beautiful is either crushed altogether or hidden in the innermost depths, as a great sin, that dares not face the light.

As all those have shown who have discussed civil institutions, and as every history is full of examples, it is necessary to whoever arranges to found a Republic and establish laws in it, to presuppose that all men are bad and that they will use their malignity of mind every time they have the opportunity; and if such malignity is hidden for a time, it proceeds from the unknown reason that would not be known because the experience of the contrary had not been seen, but time, which is said to be the father of every truth, will cause it to be discovered.

The education of the common people requires, perhaps, in a civilized and commercial society, the attention of the public more than that of people of some rank and fortune.

When I speak of 'negative dialectics' not the least important reason for doing so is my desire to dissociate myself from this fetishization of the positive.

Totalitarianism in power invariably replaces all first-rate talents, regardless of their sympathies, with those crackpots and fools whose lack of intelligence and creativity is still the best guarantee of their loyalty.

As a way of maintaining relative intellectual independence, having the attitude of an amateur instead of a professional is a better course.

Orb webs in real life do their business largely in two dimensions. If the mesh is too coarse, flies pass straight through. If the mesh is too fine, rival spiders will achieve nearly the same result at less cost in silk, and will therefore leave behind more progeny to carry on their economically more prudent genes. Natural selection finds the efficient compromise.

I know now that I shall. But all Actual Knowledge brings with it, by its formal nature, its schematised apposition; - although I now know of the Schema of God, yet I am not yet immediately this Schema, but I am only a Schema of the Schema. The required Being is not yet realised. I shall be. Who is this I? Evidently that which is, - the Ego gives in Intuition, the Individual. This shall be. What does its Being signify? It is given as a Principle in the World of Sense. Blind Instinct is indeed annihilated, and in its place there now stands the clearly perceived Shall. But the Power that at first set this Instinct in motion remains, in order that the Shall my now set it (the Power) in motion, and become its higher determining Principle. By means of this Power, I shall therefore, within its sphere, - the World of Sense, - produce and make manifest that which I recognise as my true Being in the Supersensuous World.

And because it may be too great a temptation to human frailty, apt to grasp at power, for the same persons, who have the power of making laws, to have also in their hands the power to execute them, whereby they may exempt themselves from obedience to the laws they make, and suit the law, both in its making, and execution, to their own private advantage...

When you know that every problem is only a false problem, you are dangerously close to salvation.

Man does not exercise his thought because he finds it amusing, but because, obliged as he is to live immersed in the world and to force his way among things, he finds himself under the necessity of organizing his psychic activities, which are not very different from those of the anthropoid, in the form of thought - which is what the animal does not do.

Let me never fall into the vulgar mistake of dreaming that I am persecuted whenever I am contradicted.

Superstition is now in her turn cast down and trampled underfoot, whilst we by the victory are exalted high as heaven.

I respect orders but I respect myself too and I do not obey foolish rules made especially to humiliate me.

Creation is in fact a fault, man's famous sin thereby appearing as a minor version of a much graver one. What are we guilty of, except of having followed, more or less slavishly, the Creator's example? Easy to recognize in ourselves the fatality which was His: not for nothing have we issued from the hands of a wicked and woebegone god, a god accursed.

What so impressed me on that first reading was the self-containedness of Tolkien's world. I suppose there are a few novelists who have created worlds that are uniquely their own -- Faulkner, for example, or Dickens. But since their world is fairly close to the actual world, it cannot really be called a unique creation. The only parallel that occurs to me is the Wagner Ring cycle, that one can only enter as if taking a holiday on a strange planet.

Applied knowledge in the Renaissance had to take the form of translation of the auditory into visual terms, of the plastic into retinal form.

Ambition is a drug that makes its addicts potential madmen.

The appearance in nineteenth-century psychiatry, jurisprudence, and literature of a whole series of discourses on the species and subspecies of homosexuality, inversion, pederasty, and "psychic hermaphroditism" made possible a strong advance of social controls into this area of "perversity"; but it also made possible the formation of a "reverse" discourse: homosexuality began to speak in its own behalf, to demand that its legitimacy or "naturality" be acknowledged, often in the same vocabulary, using the same categories by which it was medically disqualified.
