The best definition of man is: a being that goes on two legs and is ungrateful.

Irony is the form of paradox. Paradox is what is good and great at the same time.

Stars and blossoming fruit-trees: utter permanence and extreme fragility give an equal sense of eternity.

Seek after the good, and with much toil shall ye find it; the evil turns up of itself without your seeking it.

"If a nation expects to be ignorant and free," said Jefferson, "it expects what never was and never will be."

Social and economic inequalities, for example inequalities of wealth and authority, are just only if they result in compensating benefits for everyone, and in particular for the least advantaged members of society.

The learning of the gentleman enters through his ears, fastens to his heart, spreads through his four limbs, and manifests itself in his actions. ... The learning of the petty person enters through his ears and passes out his mouth. From mouth to ears is only four inches-how could it be enough to improve a whole body much larger than that?

Never has any one been less a priest than Jesus, never a greater enemy of forms, which stifle religion under the pretext of protecting it. By this we are all his disciples and his successors; by this he has laid the eternal foundation-stone of true religion; and if religion is essential to humanity, he has by this deserved the Divine rank the world has accorded him.

The human race's prospects of survival were considerably better when we were defenceless against tigers than they are today when we have become defenceless against ourselves.

One who believes, as I do, that the free intellect is the chief engine of human progress, cannot but be fundamentally opposed to Bolshevism, as much as to the Church of Rome.

How many valiant men we have seen to survive their own reputation!

Is a democracy, such as we know it, the last improvement possible in government? Is it not possible to take a step further towards recognizing and organizing the rights of man? There will never be a really free and enlightened State until the State comes to recognize the individual as a higher and independent power, from which all its own power and authority are derived, and treats him accordingly. I please myself with imagining a State at least which can afford to be just to all men, and to treat the individual with respect as a neighbor; which even would not think it inconsistent with its own repose if a few were to live aloof from it, not meddling with it, nor embraced by it, who fulfilled all the duties of neighbors and fellow-men. A State which bore this kind of fruit, and suffered it to drop off as fast as it ripened, would prepare the way for a still more perfect and glorious State, which also I have imagined, but not yet anywhere seen.

'Tis a grievous thing to be subject to an inferior.

Those who claim to care about the wellbeing of human beings and the preservation of our environment should become vegetarians for that reason alone. They would thereby increase the amount of grain available to feed people elsewhere, reduce pollution, save water and energy, and cease contributing to the clearing of forests; moreover, since a vegetarian diet is cheaper than one based on meat dishes, they would have more money available to devote to famine relief, population control, or whatever social or political cause they thought most urgent. ... when nonvegetarians say that "human problems come first" I cannot help wondering what exactly it is that they are doing for human beings that compels them to continue to support the wasteful, ruthless exploitation of farm animals.

We boil at different degrees.

...an intellectual concept abstracts from everything sensuous, it is not abstracted from sensuous things, and perhaps would be more correctly called abstracting than abstract. Intellectual concepts it is more cautious, therefore, to call pure ideas, and concepts given only empirically, abstract ideas.

What a singular destiny has been that of this remarkable man! To be regarded in his own age as a classic, and in ours as a companion! To receive from his contemporaries that full homage which men of genius have in general received only from posterity! To be more intimately known to posterity than other men are known to their contemporaries!

A teacher who can show good, or indeed astounding results while he is teaching, is still not on that account a good teacher, for it may be that, while his pupils are under his immediate influence, he raises them to a level which is not natural to them, without developing their own capacities for work at this level, so that they immediately decline again once the teacher leaves the schoolroom.

The origin of our passions, the root and spring of all the rest, the only one which is born with man, which never leaves him as long as he lives, is self-love; this passion is primitive, instinctive, it precedes all the rest, which are in a sense only modifications of it. In this sense, if you like, they are all natural. But most of these modifications are the result of external influences, without which they would never occur, and such modifications, far from being advantageous to us, are harmful. They change the original purpose and work against its end; then it is that man finds himself outside nature and at strife with himself.

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

Whereas logic and objectivity are usually the predominant features of a man's outer attitude, or are at least regarded as ideals, in the case of a woman it is feeling. But in the soul it is the other way round: inwardly it is the man who feels, and the woman who reflects. Hence a man's greater liability to total despair, while a woman can always find comfort and hope; accordingly a man is more likely to put an end to himself than a woman. However much a victim of social circumstances a woman may be, as a prostitute for instance, a man is no less a victim of impulses from the unconscious, taking the form of alcoholism and other vices.

To ascend to the origin of things and speculate on the creation, is not the business of the natural philosopher. An humbler field is sufficient for him in the endeavor to discover, as far as our faculties will permit; what are these primary qualities impressed on matter, and to discover the spirit of the laws of nature

O tenderly the haughty day Fills his blue urn with fire; One morn is in the mighty heaven, And one in our desire.

Let us now enquire whether anger be in accordance with nature, and whether it be useful and worth entertaining in some measure.

One of the most striking signs of the decay of art is the intermixing of different genres.

The Law continues to exist and to function. But it no longer exists for me.

Reason is the greatest enemy that faith has: it never comes to the aid of spiritual things, but--more frequently than not--struggles against the divine Word, treating with contempt all that emanates from God.

It is often said that experiments should be made without preconceived ideas. That is impossible. Not only would it make every experiment fruitless, but even if we wished to do so, it could not be done. Every man has his own conception of the world, and this he cannot so easily lay aside. We must, for example, use language, and our language is necessarily steeped in preconceived ideas.

The lover who kills himself for a girl has an experience which is more complete and much more profound than the hero who overturns the world.

In every man's writings, the character of the writer must lie recorded.

The contradiction is this: man rejects the world as it is, without accepting the necessity of escaping it. In fact, men cling to the world and by far the majority do not want to abandon it.

At last I have attained true glory. As I walked through Fleet Street the day before yesterday, I saw a copy of Hume at a bookseller's window with the following label: "Only 2l. 2s. Hume's History of England in eight volumes, highly valuable as an introduction to Macaulay." I laughed so convulsively that the other people who were staring at the books took me for a poor demented gentleman.

Often it is only after immense intellectual effort, which may have continued over centuries, that humanity at last succeeds in achieving knowledge of a concept in its pure form, by stripping off the irrelevant accretions which veil it from the eye of the mind.

Of our desires some are natural and necessary, others are natural but not necessary; and others are neither natural nor necessary, but are due to groundless opinion.

The best way to drive out the devil, if he will not yield to texts of Scripture, is to jeer and flout him, for he cannot bear scorn. 

Astronomers... define duration in the following way: time... so defined that Newton's law and that of vis viva [or of the conservation of energy] may be verified. Newton's law is an experimental truth... only approximate... We still have only a definition by approximation.

The function of objective thinking is to reduce all phenomena which bear witness to the union of subject and world, putting in their place the clear idea of the object as in itself and of the subject as pure consciousness. It therefore severs the links which unite the thing and the embodied subject, leaving only sensible qualities to make up our world (to the exclusion of the modes of appearance which we have described), and preferably visual qualities, because these give the impression of being autonomous, and because they are less directly linked to our body and present us with an object rather than introducing us into an atmosphere. But in reality all things are concretions of a setting, and any explicit perception of a thing survives in virtue of a previous communication with a certain atmosphere.

I have said these things to you so that by means of me you may have peace. In the world you will have tribulation, but take courage! I have conquered the world.

Distinctive signs, full signs, never seduce us.

Marriage and dependent children are a trap for the people! Morality carefully hides this distressing truth from us because it knows no remedy for the evil. But I , who bring a remedy must not dissimulate the woes from fathers, and I must not dissimulate from society its radical vice of pushing seven-eighths of all families into evil practices through poverty.

Any loss of identity prompts people to seek reassurance and rediscovery of themselves by testing, and even by violence. Today, the electric revolution, the wired planet, and the information environment involve everybody in everybody to the point of individual extinction.

To the Whigs of the seventeenth century we owe it that we have a House of Commons. To the Whigs of the nineteenth century we owe it that the House of Commons has been purified. The abolition of the slave trade, the abolition of colonial slavery, the extension of popular education, the mitigation of the rigour of the penal code, all, all were effected by that party; and of that party, I repeat, I am a member. I look with pride on all that the Whigs have done for the cause of human freedom and of human happiness. I see them now hard pressed, struggling with difficulties, but still fighting the good fight. At their head I see men who have inherited the spirit and the virtues, as well as the blood, of old champions and martyrs of freedom... While one shred of the old banner is flying, by that banner will I at least be found.

To imagine that Caesar aspired to do something in the way Alexander did it - and this is what almost all historians have believed - is definitely to give up trying to understand him. Caesar is very nearly the opposite of Alexander. ...[I]t is not merely a universal kingdom that Caesar has in view. His purpose is a deeper one. He wants a Roman empire which does not live on Rome, but on the periphery, on the provinces, and this implies the complete supersession of the City-State. It implies a State in which the most diverse peoples collaborate, in regard to which all feel solidarity.

As the soul is the life of the body, so God is the life of the soul. As therefore the body perishes when the soul leaves it, so the soul dies when God departs from it.

... our descendants may recognize that we are the sociopathic emotional primitives in the grip of an affective psychosis. Jealousy, envy, resentment, ridicule, hate, anger, disgust, spite, contempt, schadenfreude and a whole gamut of nameless but mean-spirited states we undergo each day are a toxic legacy of our Darwinian past. More commonly, perhaps, our genetic make-up ensures we simply feel indifference to the plight of all but a handful of significant others in our lives. Right now, for instance, one knows dimly at some level that there is frightful and preventable suffering in the world. Yet most of us feel no overpowering moral urgency to do anything about it.

When the imagination sleeps, words are emptied of their meaning: a deaf population absent-mindedly registers the condemnation of a man. ... there is no other solution but to speak out and show the obscenity hidden under the verbal cloak.
