Identical in the physical processes by which he originates-identical in the early stages of his formation-identical in the mode of his nutrition before and after birth, with the animals which lie immediately below him in the scale-Man, if his adult and perfect structure be compared with theirs, exhibits, as might be expected, a marvellous likeness of organization. He resembles them as they resemble one another-he differs from them as they differ from one another.-And, though these differences and resemblances cannot be weighed and measured, their value may be readily estimated; the scale or standard of judgment, touching that value, being afforded and expressed by the system of classification of animals now current among zoologists.

The sense of justice and injustice is not deriv'd from nature, but arises artificially... from education, and human conventions.

The basic paradox about sex is that it always seems to be offering more than it can deliver. A glimpse of a girl undressing through a lighted bedroom window induces a vision of ecstatic delight, but in the actual process of persuading the girl into bed, the vision somehow evaporates.

There is merely bad luck in not being loved; there is misfortune in not loving. All of us, today, are dying of this misfortune. For violence and hatred dry up the heart itself; the long fight for justice exhausts the love that nevertheless gave birth to it.

Anyone who is not shocked by quantum theory has not understood it.

I suppose I must be out of sorts to feel everything so deeply. Sometimes, however, it seems to me that i am not really a human being at all, but like a bird or a beast in human form. I feel so much more at home even in a scrap of garden like the one here, and still more in the meadows when the grass is humming with bees than - at one of the our party congresses.

The difference between a Humanist and a lunatic is in fact one of degree.

My dear reader, read aloud, if possible! If you do so, allow me to thank you for it: if you not only do it yourself, if you also influence others to do it, allow me to thank each one of them, and you again and again!

Perhaps no person can be a poet, or even enjoy poetry, without a certain unsoundness of mind.

Originality is a thing we constantly clamour for, and constantly quarrel with; as if, observes our author himself, any originality but our own could be expected to content us! In fact all strange thing are apt, without fault of theirs, to estrange us at first view, and unhappily scarcely anything is perfectly plain, but what is also perfectly common.

There's something that remains barbarous in educated people, and lately I've more and more had the feeling that we are nonwondering primitives. And why is it that we no longer marvel at these technological miracles? They've become the external facts of every life. We've all been to the university, we've had introductory courses in everything, and therefore we have persuaded ourselves that if we had the time to apply ourselves to these scientific marvels, we would understand them. But of course that's an illusion. It couldn't happen. Even among people who have had careers in science. They know no more about how it all works than we do. So we are in the position of savage men who, however, have been educated into believing that they are capable of understanding everything. Not that we actually do understand, but that we have the capacity.

If...we look at the essential characteristics of the Whig and the Tory, we may consider each of them as the representative of a great principle, essential to the welfare of nations. One is, in an especial manner, the guardian of liberty, and the other, of order. One is the moving power, and the other the steadying power of the state. One is the sail, without which society would make no progress, the other the ballast, without which there would be small safety in a tempest.

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.

The aim of philosophy is to erect a wall at the point where language stops anyway.

The sphere of consciousness shrinks in action; no one who acts can lay claim to the universal, for to act is to cling to the properties of being at the expense of being itself, to form a reality to reality's detriment.

When one admits that nothing is certain one must, I think, also admit that some things are much more nearly certain than others. It is much more nearly certain that we are assembled here tonight than it is that this or that political party is in the right. Certainly there are degrees of certainty, and one should be very careful to emphasize that fact, because otherwise one is landed in an utter skepticism, and complete skepticism would, of course, be totally barren and completely useless.

There is no road or ready way to virtue.

In the face of the idea that truth might afford the opposite of satisfaction and turn out to be completely shocking to humanity at any given historical moment, ... the fathers of pragmatism made the satisfaction of the subject the criterion of truth. For such a doctrine there is no possibility of rejecting or even criticizing any species of belief that is enjoyed by its adherents.

The blindness of those who think it absurd to suppose that complex organic forms may have arisen by successive modifications out of simple ones becomes astonishing when we remember that complex organic forms are daily being thus produced. A tree differs from a seed immeasurably in every respect... Yet is the one changed in the course of a few years into the other: changed so gradually, that at no moment can it be said - Now the seed ceases to be, and the tree exists.

All things as subsist from nature appear to contain in themselves a principle of motion and permanency; some according to place, others according to increase and diminuation; and others according to change in quality. 

What ideas individuals may attach to the term "Millennium" I know not; but I know that society may be formed so as to exist without crime, without poverty, with health greatly improved, with little, if any misery, and with intelligence and happiness increased a hundredfold; and no obstacle whatsoever intervenes at this moment except ignorance to prevent such a state of society from becoming universal.

He that uses his words loosely and unsteadily will either not be minded or not understood.

There are two ways in which a science develops; in response to problems which is itself creates, and in response to problems that are forced on it from the outside.

To constrain the brute force of the people, the European governments deem it necessary to keep them down by hard labor, poverty and ignorance, and to take from them, as from bees, so much of their earnings, as that unremitting labor shall be necessary to obtain a sufficient surplus to sustain a scanty and miserable life.

Nothing can come out of nothing, any more than a thing can go back to nothing.

Being happy involves both a certain achievement in action and a rational assurance about the outcome.

These numerous points at which money is withdrawn from circulation and accumulated in numerous individual hoards or potential money-capitals appears as so many obstacles to circulation, because they immobilise the money and deprive it of its capacity to circulate for a certain time.

Suffering is a spiritual thing. It is the most immediate revelation of consciousness, and it may be that our body was given us simply in order that suffering might be enabled to manifest itself. A man who had never known suffering, either in greater or less degree, would scarcely possess consciousness of himself. The child first cries at birth when the air, entering into his lungs and limiting him, seems to say to him: You have to breathe me in order to live!

In order to make himself thoroughly undesirable, he will speak.

And Jesus answered and said unto her, Martha, Martha, thou art careful and troubled about many things, but one thing is needful: and Mary hath chosen that good part, which shall not be taken away from her.

What should a philosopher say, then, in the face of each of the hardships of life? "It was for this that I've been training myself, it was for this that I was practising."

I should have loved freedom, I believe, at all times, but in the time in which we live I am ready to worship it.

It is crazy to want what is impossible. And impossible for the wicked not to do so.

The concrete man has but one interest - to be right. That to him is the art of all arts, and all means are fair which help him to it.

What has been shown by Machiavelli, who is often (like Nietzsche) congratulated for tearing off hypocritical masks, brutally revealing the truth, and so on, is not that men profess one thing and do another (although no doubt he shows this too) but that when they assume that the two ideals are compatible, or perhaps are even one and the same ideal, and do not allow this assumption to be questioned, they are guilty of bad faith (as the existentialists call it, or of "false consciousness," to use a Marxist formula) which their actual behavior exhibits. Machiavelli calls the bluff not just of official morality-the hypocrisies of ordinary life-but of one of the foundations of the central Western philosophical tradition, the belief in the ultimate compatibility of all genuine values. His own withers are unwrung. He has made his choice. He seems wholly unworried by, indeed scarcely aware of, parting company with traditional Western morality.

The pursuit of philosophy is founded on the belief that knowledge is good, even if what is known is painful. A man imbued with the philosophic spirit, whether a professional philosopher or not, will wish his beliefs to be as true as he can make them, and will, in equal measure, love to know and hate to be in error. This principle has a wider scope than may be apparent at first sight.

The socialist system of society should only be, and can only be, an historical product, born out of the school of its own experiences, born in the course of its realization, as a result of the developments of living history, which - just like organic nature of which, in the last analysis, it forms a part - has the fine habit of always producing along with any real social need the means to its satisfaction, along with the task simultaneously the solution. However, if such is the case, then it is clear that socialism by its very nature cannot be decreed or introduced by ukase. It has as its prerequisite a number of measures of force - against property, etc. The negative, the tearing down, can be decreed; the building up, the positive, cannot. New Territory. A thousand problems. Only experience is capable of correcting and opening new ways.

Survive in such a way that you avoid limiting others who are also trying to survive. We all live in limited systems. This is the core of ethics.

Two things in America are astonishing: the changeableness of most human behavior and the strange stability of certain principles. Men are constantly on the move, but the spirit of humanity seems almost unmoved.

It is not by genius, it is by suffering, and suffering alone, that one ceases to be a marionette.

I believe that love is the main key to open the doors to the "growth" of man. Love and union with someone or something outside of oneself, union that allows one to put oneself into relationship with others, to feel one with others, without limiting the sense of integrity and independence. Love is a productive orientation for which it is essential that there be present at the same time: concern, responsibility, and respect for and knowledge of the object of the union. I believe that the experience of love is the most human and humanizing act that it is given to man to enjoy and that it, like reason, makes no sense if conceived in a partial way.

Capitalism dislikes silence.

Blood will stream over Europe until the nations become aware of the frightful madness which drives them in circles. And then, struck by celestial music and made gentle, they approach their former altars all together, hear about the works of peace, and hold a great celebration of peace with fervent tears before the smoking altars.

Morality must be the heart of our existence, if it is to be what it wants to be for us. ... The highest form of philosophy is ethics. Thus all philosophy begins with "I am." The highest statement of cognition must be an expression of that fact which is the means and ground for all cognition, namely, the goal of the I.

Against the many Russian thinkers influenced by Hegel who believed that history was governed by universal laws to which one could only submit, Turgenev upheld the freedom of different societies to pursue different paths of development and of individuals to pursue, even in opposition to powerful historical forces, their own goals and values. Here Turgenev endorsed the celebrated dictum of Alexander Herzen, with whom he disagreed on other matters: that history has no libretto. Human history is a realm of contingency and unpredictability, in which each generation faces conflicts that have no ideal solution.

The greatness of America lies not in being more enlightened than any other nation, but rather in her ability to repair her faults.
