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.

Those of our pleasures which come most rarely give the greatest delight.

Where the world comes in my way - and it comes in my way everywhere - I consume it to quiet the hunger of my egoism. For me you are nothing but - my food, even as I too am fed upon and turned to use by you. We have only one relation to each other, that of usableness, of utility, of use.

Conservatives have, on the whole, accepted nationality as a sphere of local duties and loyalties, defining an inheritance and a community that has a right to pass on its values from generation to generation. The nation may indeed be the best that we now have, by way of a society linking the dead to the unborn, in the manner extolled by Burke. And for this very reason it arouses the hostility of liberals, who are constantly searching for a place outside loyalty and obedience, from which all human claims can be judged. Hence, in the conflicts of our times, while conservatives leap to the defense of the nation and its interests, wishing to maintain its integrity and to enforce its law, liberals advocate transnational initiatives, international courts, and doctrines of universal rights, all of which, they believe, should stand in judgment over the nation and hold it to account.

The public has yet to see TV as TV. Broadcasters have no awareness of its potential. The movie people are just beginning to get a grasp on film.

A man is more a man through the things he keeps to himself than through those he says.

Not one moment when I have not been conscious of being outside Paradise.

Cease therefore to be dismayed by the mere novelty and so to reject reason from your mind with loathing: weigh the questions rather with keen judgment and if they seem to you to be true, surrender, or if the thing is false, gird yourself to the encounter.

To none is life given in freehold; to all on lease.

Deep in the man sits fast his fate To mould his fortunes, mean or great.

I suggest that scientific knowledge, though logically more articulate and far more complex, is of this sort. The books and teachers from whom it is acquired present concrete examples together with a multitude of theoretical generalizations. Both are essential carriers of knowledge, and it is therefore Pickwickian to seek a methodological criterion that supposes the scientist can specify in advance whether each imaginable instance fits or would falsify his theory.

Reason has discovered the struggle for existence and the law that I must throttle all those who hinder the satisfaction of my desires. That is the deduction reason makes. But the law of loving others could not be discovered by reason, because it is unreasonable.

Ireland still remains the Holy Isle whose aspirations must on no account be mixed with the profane class-struggles of the rest of the sinful world ... the Irish peasant must not on any account know that the Socialist workers are his sole allies in Europe.

Choose your parents wisely.

Scientists work from models acquired through education and through subsequent exposure to the literature often without quite knowing or needing to know what characteristics have given these models the status of community paradigms.

When an active individual of sound common sense perceives the sordid state of the world, desire to change it becomes the guiding principle by which he organizes given facts and shapes them into a theory. The methods and categories as well as the transformation of the theory can be understood only in connection with his taking of sides. This, in turn, discloses both his sound common sense and the character of the world. Right thinking depends as much on right willing as right willing on right thinking.

Eros and depression are opposites.

That fear which gives birth to thoughts, and the fear of thoughts...

My education, which was wholly his work, had been conducted without any regard to the possibility of its ending in this result; and I saw no use in giving him the pain of thinking that his plans had failed, when the failure was probably irremediable, and, at all events, beyond the power of his remedies. Of other friends, I had at that time none to whom I had any hope of making my condition intelligible. It was however abundantly intelligible to myself; and the more I dwelt upon it, the more hopeless it appeared.

I have enough to eat till my hunger is stayed, to drink till my thirst is sated; to clothe myself withal; and out of doors not Callias there, with all his riches, is more safe than I from shivering; and when I find myself indoors, what warmer shirting do I need than my bare walls? what ampler greatcoat than the tiles above my head?

To stand on one leg and prove God's existence is a very different thing from going on one's knees and thanking Him.

But it has been necessary, for the benefit of the social order, to convert religion into a kind of police system, and hence hell. Oriental or Greek Christianity is predominantly eschatological, Protestantism predominantly ethical, and Catholicism is a compromise between the two, although with the eschatological element predominating.

The aim of science is to seek the simplest explanations of complex facts. We are apt to fall into the error of thinking that the facts are simple because simplicity is the goal of our quest. The guiding motto in the life of every natural philosopher should be, "Seek simplicity and distrust it."

The principles of great men illuminate the universe.

Ideas should be neutral. But man animates them with his passions and folly. Impure and turned into beliefs, they take on the appearance of reality. The passage from logic is consummated. Thus are born ideologies, doctrines, and bloody farce.

The normal present connects the past and the future through limitation. Contiguity results, crystallization by means of solidification. There also exists, however, a spiritual present that identifies past and future through dissolution, and this mixture is the element, the atmosphere of the poet.

It is a very hard undertaking to seek to please everybody.

When we consider the being and substance of that universe in which we are immutably set, we shall discover that neither we ourselves nor any substance doth suffer death; for nothing is in fact diminished in its substance, but all things, wandering through infinite space, undergo change of aspect.

They [the wise spirits of antiquity in the first circle of Dante's Inferno] are condemned, Dante tells us, to no other penalty than to live in desire without hope, a fate appropriate to noble souls with a clear vision of life.

I pride myself on my capacity to perceive the transitory character of everything. An odd gift which has spoiled all my joys; better: all my sensations.

This reasonable moderator, and equal piece of justice, Death.

People will do anything, no matter how absurd, in order to avoid facing their own souls. They will practice Indian yoga and all its exercises, observe a strict regimen of diet, learn the literature of the whole world-all because they cannot get on with themselves and have not the slightest faith that anything useful could ever come out of their own souls. Thus the soul has gradually been turned into a Nazareth from which nothing good can come.

The public, therefore, among a democratic people, has a singular power, which aristocratic nations cannot conceive; for it does not persuade others to its beliefs, but it imposes them and makes them permeate the thinking of everyone by a sort of enormous pressure of the mind of all upon the individual intelligence.

Everywhere we remain unfree and chained to technology, whether we passionately affirm or deny it. But we are delivered over to it in the worst possible way when we regard it as something neutral; for this conception of it, to which today we particularly like to do homage, makes us utterly blind to the essence of technology.

I have learned to seek my happiness by limiting my desires, rather than in attempting to satisfy them.

...the French business is no light or trivial thing, or such as has commonly occurd in the course of political Events. At present the whole political State of Europe hinges upon it. On the Continent there is little doubt; every thing will take is future shape and colour from the good or ill success of the Duke of Brunswick. In my opinion, it is the most important crisis that ever existed in the World. ... My poor opinion is, that these principles...cannot possibly be realized in practice in France, without an absolute certainty and that at no remote period, of overturning the whole fabrick of the British Constitution.

She [virtue] requires a rough and stormy passage; she will have either outward difficulties to wrestle with, ... or internal difficulties.

Private property has made us so stupid and one-sided that an object is only ours when we have it - when it exists for us as capital, or when it is directly possessed, eaten, drunk, worn, inhabited, etc., - in short, when it is used by us. Although private property itself again conceives all these direct realizations of possession as means of life, and the life which they serve as means is the life of private property - labour and conversion into capital. In place of all these physical and mental senses there has therefore come the sheer estrangement of all these senses - the sense of having. The human being had to be reduced to this absolute poverty in order that he might yield his inner wealth to the outer world.

There is no wish more natural than the wish to know.

I must before I die, find some way to say the essential thing that is in me, that I have never said yet - a thing that is not love or hate or pity or scorn, but the very breath of life, fierce and coming from far away, bringing into human life the vastness and fearful passionless force of non-human things...

We do not know nature; causes hidden in her breast might have produced everything. In your turn, observe the polyp of Trembley: does it not contain in itself the causes which bring about regeneration? Why then would it be absurd to think that there are physical causes by reason of which everything has been made, and to which the whole chain of this vast universe is so necessarily bound and held that, nothing which happens, could have failed to happen,-causes, of which we are so invincibly ignorant that we have had recourse to a God, who, as some aver, is not so much as a logical entity? Thus to destroy chance is not to prove the existence of a supreme being, since there may be some other thing which is neither chance nor God-I mean, nature. It follows that the study of nature can make only unbelievers; and the way of thinking of all its more successful investigators proves this.

The refusal of work and authority, or really the refusal of voluntary servitude, is the beginning of liberatory politics.

Democracies owe their existence to national loyalties - the loyalties that are supposedly shared by government and opposition, by all political parties, and by the electorate as a whole. Wherever the experience of nationality is weak or non-existent, democracy has failed to take root. For without national loyalty, opposition is a threat to government, and political disagreements create no common ground.

The world would be a happier place than it is if acquisitiveness were always stronger than rivalry. But in fact, a great many men will cheerfully face impoverishment if they can thereby secure complete ruin for their rivals. Hence the present level of taxation. Vanity is a motive of immense potency. Anyone who has much to do with children knows how they are constantly performing some antic, and saying "Look at me." "Look at me" is one of the most fundamental desires of the human heart. It can take innumerable forms, from buffoonery to the pursuit of posthumous fame.

When the world presents as a force field of violence, the task of nonviolence is to find ways of living and acting in that world such that violence is checked or ameliorated, or its direction turned, precisely at moments when it seems to saturate that world and offer no way out.

I wish to propose for the reader's favourable consideration a doctrine which may, I fear, appear wildly paradoxical and subversive. The doctrine in question is this: that it is undesirable to believe a proposition when there is no ground whatever for supposing it true.

For where God built a church, there the Devil would also build a chapel...Thus is the Devil ever God's ape.
