Let the eye of vigilance never be closed.

Sobriety is the strength of the soul, for it preserves its reason unclouded by passion.

The youth gets together his materials to build a bridge to the moon, or, perchance, a palace or temple on the earth, and, at length, the middle-aged man concludes to build a woodshed with them.

Do not ask who started it.

No matter how abstract our theories may sound or how consistent our arguments may appear, there are incidents and stories behind them which, at least for ourselves, contain as in a nutshell the full meaning of whatever we have to say.

Prosperity makes friends, adversity tries them.

The three great elements of modern civilization, gunpowder, printing, and the Protestant religion.

Tis the sharpness of our mind that gives the edge to our pains and pleasures.

All life, Omnipotent Father, is thy life! and the eye of religion alone penetrates to the realms of truth and beauty. I am related to thee, and what I behold around me is related to me; all is full of animation, and looks towards me with bright spiritual eyes, and speaks with spirit voices to my heart.

A true friend will partake of the wants and sorrows of his friend, as if they were his own; if he be in want, he will relieve him; if he be in prison, he will visit him; if he be sick, he will come to him; nay-situations may occur, in which he would not scruple to die for him. It cannot then be doubted, that friendship is one of the most useful means of procuring a secure, tranquil, and happy life.

The general reference of the philosophical discussion is usually the triangle world: world-language-subject, the relation of the subject to the world of objects, mediated through language.

An individual may perceive a way of life, or a method of social organisation, by which more of the desires of mankind could be satisfied than under the existing method. If he perceives truly, and can persuade men to adopt his reform, he is justified. Without rebellion, mankind would stagnate, and injustice would be irremediable.

Attention is the rarest and purest form of generosity.

A man must always live by his work, and his wages must at least be sufficient to maintain him. They must even upon most occasions be somewhat more, otherwise it would be impossible for him to bring up a family, and the race of such workmen could not last beyond the first generation.

Interest only becomes one-sided and morbid only when it ceases to be frank, and becomes sly and furtive.

You [a disciple], shall I teach you about knowledge? What you know, you know, what you don't know, you don't know. This is true knowledge.

What really matters is that we should all of us realize that we are guilty of inhumanity. The horror of this realization should shake us out of our lethargy so that we can direct our hopes and our intentions to the coming of an era in which war will have no place.

The best books are those, which those who read them believe they themselves could have written.

Whensoever therefore the legislative shall transgress this fundamental rule of society; and either by ambition, fear, folly or corruption, endeavour to grasp themselves, or put into the hands of any other, an absolute power over the lives, liberties, and estates of the people; by this breach of trust they forfeit the power the people had put into their hands for quite contrary ends, and it devolves to the people, who have a right to resume their original liberty, and, by the establishment of a new legislative, (such as they shall think fit) provide for their own safety and security, which is the end for which they are in society.

We have learned to tolerate the facts of war: that men are killed en masse - some twenty million in the Second World War - that whole cities and their inhabitants are annihilated by the atomic bomb, that men are turned into living torches by incendiary bombs. We learn of these things from the radio or newspapers and we judge them according to whether they signify success for the group of peoples to which we belong, or for our enemies. When we do admit to ourselves that such acts are the results of inhuman conduct, our admission is accompanied by the thought that the very fact of war itself leaves us no option but to accept them. In resigning ourselves to our fate without a struggle, we are guilty of inhumanity.

Danger reawakens the spirit.

Man is not the creature and product of Mechanism; but, in a far truer sense, its creator and producer: it is the noble People that makes the noble Government; rather than conversely.

There is perhaps nothing more interesting than to listen to a superior man talk of what he does not know. He advances slowly, and scarcely puts his foot down without knowing if the ground is solid; he looks for plausible analogies; he tries to attach his ideas to higher and incontestable principles; he always has the tone of looking, never that of teaching; and it often happens that, even if he is mistaken, he leaves a great enough idea of his mental honesty.

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.

One cannot demand of a scholar that he show himself a scholar everywhere in society, but the whole tenor of his behavior must none the less betray the thinker, he must always be instructive, his way of judging a thing must even in the smallest matters be such that people can see what it will amount to when, quietly and self-collected, he puts this power to scholarly use.

There can be no difference anywhere that doesn't make a difference elsewhere - no difference in abstract truth that doesn't express itself in a difference in concrete fact and in conduct consequent upon that fact, imposed on somebody, somehow, somewhere and somewhen.

If by enlightenment and intellectual progress we mean the freeing of man from superstitious belief in evil forces, in demons and fairies, in blind fate-in short, emancipation of fear-then denunciation of what is currently called reason is the greatest service reason can render.

It was mathematics, the non-empirical science par excellence, wherein the mind appears to play only with itself, that turned out to be the science of sciences, delivering the key to those laws of nature and the universe that are concealed by appearances.

Only at quite rare moments have I felt really glad to be alive. I could not but feel with a sympathy full of regret all the pain that I saw around me, not only that of men but that of the whole creation. From this community of suffering I have never tried to withdraw myself. It seemed to me a matter of course that we should all take our share of the burden of pain which lies upon the world.

A blow from your friend is better than a kiss from your enemy.

Young man! Deny yourself satisfaction (of amusement, of debauchery, of love, etc.), not with the Stoical intention of complete abstinence, but with the refined Epicurean intention of having in view an ever-growing pleasure. This stinginess with the cash of your vital urge makes you definitely richer through the postponement of pleasure, even if you should, for the most part, renounce the indulgence of it until the end of your life. The awareness of having pleasure under your control is, like everything idealistic, more fruitful and more abundant than everything that satisfies the sense through indulgence because it is thereby simultaneously consumed and consequently lost from the aggregate of totality.

What I liked was Thatcherism's Bolshevik aspect, which was to shake up the whole of Britain quite fundamentally, and if you read what I wrote in those years I think you might agree that in taking the view that I did then - that this was necessary and desirable - I never subscribed to the main delusion of the Thatcherites, which was that you could change everything and everything would remain the same. If what you wanted was a very anarchic, globalised, polyglot, mixed-up society in which most of the structures which had somehow been renewed from the Edwardian period to the Sixties were destroyed, then Thatcherism was what would do the job.

Every one excels in something in which another fails.

Certain forms of sex which do not lead to children are at present punished by the criminal law: this is purely superstitious, since the matter is one which affects no one except the parties directly concerned... The peculiar importance attached, at present, to adultery is quite irrational... Moral rules ought not to be such as to make instinctive happiness impossible.

Deep within every human being there still lives the anxiety over the possibility of being alone in the world, forgotten by God, overlooked among the millions and millions in this enormous household. One keeps this anxiety at a distance by looking at the many round about who are related to him as kin and friends, but the anxiety is still there, nevertheless, and one hardly dares think of how he would feel if all this were taken away.

Every explanation is after all an hypothesis.

The concept of original sin gives us a penetrating insight into human destiny.

The end of the philosophical dialogue lies in itself; it can never serve a purpose outside of itself. Just as a sculptor does not cease to be a work of art even if it lies at the bottom of the sea, so indeed every work of philosophy endures, even if uncomprehended in its own time. One would be grateful if it were merely a matter of incomprehension. Instead, the work is usually refitted and appropriated by various entities-some playing the part of the opponent; others, that of the proponent.

Man differs from other animals in one very important respect, and that is that he has some desires which are, so to speak, infinite, which can never be fully gratified, and which would keep him restless even in Paradise. The boa constrictor, when he has had an adequate meal, goes to sleep, and does not wake until he needs another meal. Human beings, for the most part, are not like this.

A life devoted to science is therefore a happy life, and its happiness is derived from the very best sources that are open to dwellers on this troubled and passionate planet.

It appears... that a work similar in its object and general conception to that of Adam Smith, but adapted to the more extended knowledge and improved ideas of the present age, is the kind of contribution which Political Economy at present requires. The Wealth of Nations is in many parts obsolete, and in all, imperfect. Political Economy... has grown up almost from infancy since the time of Adam Smith; and the philosophy of society... has advanced many steps beyond the point at which he left it.

Every time a man is begotten and born, the clock of human life is wound up anew to repeat once more its same old tune that has already been played innumerable times, movement by movement and measure by measure, with insignificant variations.

No one has the audacity to exclaim: "I don't want to do anything!" - we are more indulgent with a murderer than with a mind emancipated from actions.

Enlighten the dark blood of your ancestors, shape their cries into speech, purify their will, widen their narrow, unmerciful brows. This is your second duty. For you are not only a slave. As soon as you were born, a new possibility was born with you, a free heartbeat stormed through the great sunless heart of your race.

What do you think of the aspect of the money market? ... This time, by the by, the thing has assumed European dimensions such as have never been seen before, and I don't suppose we'll be able to spend much longer here merely as spectators. The very fact that I've at last got round to setting up house again and sending for my books seems to me to prove that the 'mobilisation' of our persons is AT HAND.

The absolute idea is the subject in its final form, thought. The otherness and negation is the object, being. The absolute idea now has to be interpreted as objective being. Hegel's Logic thus ends where it began, with the category of being. This, however is a different being that can no longer be explained thought he concepts applied in the analysis that opened the Logic. For being now is understood in its notion that is, as a concrete totality wherein all particular forms subsist as the essential distinctions and relations of on comprehensive principle. Thus comprehended, being is nature, and dialectical thought passes on to the Philosophy of Nature.
