The argument of this book is that we, and all other animals, are machines created by our genes.

Murder begins where self-defense ends.

I am a pattern watcher.

Let us give Nature a chance; she knows her business better than we do.

The supreme maxim in scientific philosophising is this: wherever possible, logical constructions are to be substituted for inferred entities.

Tension weakens the bow; the want of it, the mind.

Faith makes us live by showing us that life, although it is dependent upon reason, has its well spring and source of power elsewhere, in something supernatural and miraculous. Cournot the mathematician, a man of singularly well-balanced and scientifically equipped mind has said that it is this tendency towards the supernatural and miraculous that gives life, and that when it is lacking, all the speculations of reason lead to nothing but affliction of the spirit. ...And in truth we wish to live.

The real, the unique misfortune: to see the light of day. A disaster which dates back to aggressiveness, to the seed of expansion and rage within origins, to the tendency to the worst which first shook them up.

The free will, the actual motor of reason in society, necessarily creates wrong. The individual must clash with the social order that claims to represent his own will in its objective form. But the wrong and the 'avenging justice' that remedies it not only expresses a 'higher logical necessity,' but also prepare the transition to a higher social form of freedom, the transition from abstract right to morality. For, in committing a wrong, and in accepting punishment for his deed, the individual becomes conscious of the 'infinite subjectivity' of his freedom. He learns that he is free only as a private person.

If you act externally with men in conformity with your rank, you should recognize, by a more secret but truer thought, that you have nothing naturally superior to them.

Any fool can make a ruleAnd every fool will mind it.

A son is a mirror in which the father sees himself reflected, and the father is a mirror in which the son sees himself as he will be in the future.

A sect or party is an elegant incognito devised to save a man from the vexation of thinking.

To master this instrument the religious thinker must make a preliminary study of logic, just as the lawyer must study legal reasoning. This is no more heretical in the one case than in the other. And logic must be learned from the ancient masters, regardless of the fact that they were not Muslims.

The modern scientific counterpart to belief in God is the belief in the universe as an organism: this disgusts me. This is to make what is quite rare and extremely derivative, the organic, which we perceive only on the surface of the earth, into something essential, universal, and eternal! This is still an anthropomorphizing of nature!

The effect of liberty to individuals is, that they may do what they please: we ought to see what it will please them to do, before we risk congratulations.

Spontaneous love can reach the point of despair, shows that it is in despair, that even when it is happy it loves with the power of despair.

As the chosen people bore in their features the sign manual of Jehovah, so the division of labour brands the manufacturing workman as the property of capital.

Corpses are more fit to be cast out than dung.

Nietzsche ... does not shy from conscious exaggeration and one-sided formulations of his thought, believing that in this way he can most clearly set in relief what in his vision and in his inquiry is different from the run-of-the-mill.

Times are changed with him who marries; there are no more by-path meadows, where you may innocently linger, but the road lies long and straight and dusty to the grave. Idleness, which is often becoming and even wise in the bachelor, begins to wear a different aspect when you have a wife to support.

We share bodies with two eyes, ten fingers, ten toes; we share life on this earth; we share capitalist regimes of production and exploitation; we share common dreams of a better future.

Things are not so painful and difficult of themselves, but our weakness or cowardice makes them so.

We have come to see that Huxley was right when he said that "a man's worst difficulties begin when he is able to do as he likes." The evidences of these greater difficulties lie all about us: in the brave and brilliant atheists who have defied the Methodist God, and have become very nervous; in the women who have emancipated themselves from the tyranny of fathers, husbands, and homes, and with the intermittent but expensive help of a psychoanalyst, are now enduring liberty as interior decorators; in the young men and women who are world-weary at twenty-two; in the multitudes who drug themselves with pleasure; in the crowds enfranchised by the blood of heroes who cannot be persuaded to take an interest in their destiny; in the millions, at last free to think without fear of priest or policeman, who have made the moving pictures and the popular newspapers what they are.

If names be not correct, language is not in accordance with the truth of things. Paraphrased as a chinese proverb stating "The beginning of wisdom is to call things by their proper name."

Isolation is the worst possible counselor.

Perseverance is more prevailing than violence; and many things which cannot be overcome when they are together, yield themselves up when taken little by little.

Hear the verbal protestations of all men: Nothing so certain as their religious tenets. Examine their lives: You will scarcely think that they repose the smallest confidence in them. The greatest and truest zeal gives us no security against hypocrisy: The most open impiety is attended with a secret dread and compunction. No theological absurdities so glaring that they have not, sometimes, been embraced by men of the greatest and most cultivated understanding. No religious precepts so rigorous that they have not been adopted by the most voluptuous and most abandoned of men.

Philosophy accepts the hard and hazardous task of dealing with problems not yet open to the methods of science - problems like good and evil, beauty and ugliness, order and freedom, life and death; so soon as a field of inquiry yields knowledge susceptible of exact formulation it is called science. Every science begins as philosophy and ends as art; it arises in hypothesis and flows into achievement.

Men will always be mad, and those who think they can cure them are the maddest of all.

In the late eighteenth and the greater part of the nineteenth centuries appeared the first marked cultural shift in the attitude taken toward change. Under the names of indefinite perfectibility, progress, and evolution, the movement of things in the universe itself and of the universe as a whole began to take on a beneficent instead of hateful aspect.

The best government is a benevolent tyranny tempered by an occasional assassination.

What we call objective reality is, in the last analysis, what is common to many thinking beings, and could be common to all; this common part, we shall see, can only be the harmony expressed by mathematical laws. It is this harmony... which is the sole objective reality, the only truth we can attain; and when I add that the universal harmony of the world is the source of all beauty, it will be understood what price we should attach to the slow and difficult progress which little by little enables us to know it better.

John - I'm trying to find the Island in the West. Sensible - You refer, no doubt to some aesthetic experience.

Everything great glitters, glitter begets ambition, and ambition can easily have caused the inspiration or what we thought to be inspiration. But reason can no longer restrain one who is lured by the fury of ambition. He tumbles where his vehement drive calls him; no longer does he choose his position, but rather chance and luster determine it.

Beauty is the mark God sets upon virtue.

It is surely delightful, Sir, to look forward to that period when a series of liberal and prudent measures shall have delivered islands, so highly favoured by the bounty of Providence, from the curse inflicted on them by the frantic rapacity of man. Then the peasant of the Antilles will no longer crawl in listless and trembling dejection round a plantation from whose fruits he must derive no advantage, and a hut whose door yields him no protection; but, when his cheerful and voluntary labour is performed, he will return with the firm step and erect brow of a British citizen from the field which is his freehold to the cottage which is his castle.

Catherine: Why commit Evil? Goetz: Because Good has already been done. Catherine: Who has done it? Goetz: God the Father. I, on the other hand, am improvising.

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

He who does not realize to what extent shifting fortune and necessity hold in subjection every human spirit, cannot regard as fellow-creatures nor love as he loves himself those whom chance separated from him by an abyss. The variety of constraints pressing upon man give rise to the illusion of several distinct species that cannot communicate.

There is object proof that homosexuality is more interesting than heterosexuality. It's that one knows a considerable number of heterosexuals who would wish to become homosexuals, whereas one knows very few homosexuals who would really like to become heterosexuals.

Having acknowledged the measure of the good to be pleasure, i.e., beauty, the European upper classes went back in their comprehension of art to the gross conception of the primitive Greeks which Plato had already condemned. And with this understanding of life, a theory of art was formulated.

It is by logic that we prove, but by intuition that we discover. To know how to criticize is good, to know how to create is better.

Manuscript culture is conversational if only because the writer and his audience are physically related by the form of publication as performance.

Adam came from great power and great wealth, but he was not worthy of you. For had he been worthy, [he would] not [have tasted] death.

All exact science is dominated by the idea of approximation. When a man tells you that he knows the exact truth about anything, you are safe in inferring that he is an inexact man.

Not everything in religion is precious or deserving of reverence. There is an inheritance of anthropocentrism, the ugly fantasy that the Earth exists to serve humans, which most secular humanists share. There is the claim of religious authorities, also made by atheist regimes, to decide how people can express their sexuality, control their fertility and end their lives, which should be rejected categorically. Nobody should be allowed to curtail freedom in these ways, and no religion has the right to break the peace.

I am an investigator by inclination. I feel a great thirst for knowledge and an impatient eagerness to advance, also satisfaction at each progressive step. There was a time when I thought that all this could constitute the honor of humanity, and I despised the mob, which knows nothing about it. Rousseau set me straight. This dazzling excellence vanishes; I learn to honor men, and would consider myself much less useful than common laborers if I did not believe that this consideration could give all the others a value, to establish the rights of humanity.

The system of technological production that we have today has been justified in terms of creating more goods to feed more people and to meet more needs. But it actually destroys more of the resources that we need in order to meet those multiple needs. If we shift to an ecological perception, a diversity perception, we realize that some of the instruments of which we are very proud are actually extremely primitive for dealing with nature. To me that is the great lesson of ecological awareness at the turn of the millennium.

Cultivate that kind of knowledge which enables us to discover for ourselves in case of need that which others have to read or be told of.
