The three great things that govern mankind are reason, passion and superstition. The first governs a few, the two last share the bulk of mankind and possess them in their turns. But superstition most powerfully produces the greatest mischief.

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

The principles of pleasure are not firm and stable. They are different in all mankind, and variable in every particular with such a diversity that there is no man more different from another than from himself at different times.

What is Europe really but a sterile trunk which owes everything to oriental grafts?

Since I would rather make of him an able man than a learned man, I would also urge that care be taken to choose a guide with a well-made rather than a well-filled head.

Liars ... when they speak the truth they are not believed.

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 anger of lovers renews the strength of love.

Manners are of more importance than laws. The law can touch us here and there, now and then. Manners are what vex or soothe, corrupt or purify, exalt or debase, barbarize or refine us, by a constant, steady, uniform, insensible operation like that of the air we breathe in.

Immortality is the privilege of the few, and, according to the Aryan conception, specifically the privilege of heroes. Continuing to live - not as a shadow, but as a demigod - is reserved to those which a special spiritual action has elevated from the one nature to the other.

Zeus, the god of gods, who rules according to law, and is able to see into such things, perceiving that an honourable race was in a woeful plight, and wanting to inflict punishment on them, that they might be chastened and improve, collected all the gods into their most holy habitation, which, being placed in the centre of the world, beholds all created things.

If some great Power would agree to make me always think what is true and do what is right, on condition of being turned into a sort of clock and wound up every morning before I got out of bed, I should instantly close with the offer. The only freedom I care about is the freedom to do right; the freedom to do wrong I am ready to part with on the cheapest terms to any one who will take it of me.

I should say that the universe is just there, and that is all.

Above all do not forget your duty to love yourself; do not permit the fact that you have been set apart from life in a way, been prevented from participating actively in it, and that you are superflous in the obtruse eyes of a busy world, above all, do not permit this to deprive you of your idea of yourself, as if your life, if lived in inwardness, did not have just as much meaning and worth as that of any human being in the eyes of all-wise Governance, and considerably more than the busy, busiest haste of busy-ness - busy with wasting life and losing itself.

The reason for sketching what's technically feasible with the tools of synthetic biology is that only after human complicity in the persistence of suffering in the biosphere is acknowledged can we hope to have an informed socio-political debate on the morality of its perpetuation. No serious ethical discussion of free-living animal suffering can begin in the absence of recognition of human responsibility for nonhuman well-being.

The teaching of my philosophy... that our whole existence is something which had better not have been, and that to disown and disclaim it is the highest wisdom.

At that moment he knew what his mother was thinking, and that she loved him. But he knew, too, that to love someone means relatively little; or, rather, that love is never wrong enough to find the word befitting it.

The range of socially permissible and desirable satisfaction is greatly enlarged, but through this satisfaction, the Pleasure Principle is reduced-deprived of the claims which are irreconcilable with the established society. Pleasure, thus adjusted, generates submission.

When the Indians complain that the English have enslaved them it is as if drunkards complained that the spirit-dealers who have settled among them have enslaved them. You tell them that they might give up drinking, but they reply that they are so accustomed to it that they cannot abstain, and that they must have alcohol to keep up their energy. Is it not the same thing with the millions of people who submit to thousands or even to hundreds, of others - of their own or other nations? If the people of India are enslaved by violence it is only because they themselves live and have lived by violence, and do not recognize the eternal law of love inherent in humanity.

It is the way of the superior man to prefer the concealment of his virtue, while it daily becomes more illustrious, and it is the way of the mean man to seek notoriety, while he daily goes more and more to ruin. It is characteristic of the superior man, appearing insipid, yet never to produce satiety; while showing a simple negligence, yet to have his accomplishments recognized; while seemingly plain, yet to be discriminating. He knows how what is distant lies in what is near. He knows where the wind proceeds from. He knows how what is minute becomes manifested. Such a one, we may be sure, will enter into virtue.

If the hypothesis of evolution is true, living matter must have arisen from non-living matter; for by the hypothesis the condition of the globe was at one time such, that living matter could not have existed in it, life being entirely incompatible with the gaseous state.

Not only does democracy make every man forget his ancestors, but also clouds their view of their descendants and isolates them from their contemporaries. Each man is for ever thrown back on himself alone, and there is danger that he may be shut up in the solitude of his own heart.

The habit of the religious way of thinking has biased our mind so grievously that we are - terrified at ourselves in our nakedness and naturalness; it has degraded us so that we deem ourselves depraved by nature, born devils.

But how much more highly do I think of these men! They can do these things, but decline to do them. To whom that ever tried have these tasks proved false? To what man did they not seem easier in the doing? Our lack of confidence is not the result of difficulty. The difficulty comes from our lack of confidence.

An atheist is just somebody who feels about Yahweh the way any decent Christian feels about Thor or Baal or the golden calf. As has been said before, we are all atheists about most of the gods that humanity has ever believed in. Some of us just go one god further.

Apollo said that every one's true worship was that which he found in use in the place where he chanced to be.

What to think of other people? I ask myself this question each time I make a new acquaintance. So strange does it seem to me that we exist, and that we consent to exist.

Printing will tell you such useful things and such interesting things that not being able to read would be as bad as not being able to see.

Someday, someday, this crazy world will have to end, And our God will take things back that He to us did lend. And if, on that sad day, you want to scold our God, Why go right ahead and scold Him. He'll just smile and nod.

This "knowing what to do"... is a matter of having the right purpose, the purpose appropriate to the situation in hand... The one who "knows what to do" is the one on whom you can rely to make the best shot at success, whenever success is possible.

We are told that Christ was killed for us, that His death has washed out our sins, and that by dying He has disabled death itself. That is the formula. That is Christianity. That is what has to be believed. Any theories we build up as to how Christ's death did all this are, in my view, quite secondary: mere plans or diagrams to be left alone if they do not help us, and, if they do help us, not to be confused with the thing itself.

Do you know that ages will pass and mankind will proclaim in its wisdom and science that there is no crime and, therefore no sin, but that there are only hungry people. "Feed them first and then demand virtue of them!" - that is what they will inscribe on their banner which they will raise against you and which will destroy your temple.

If it were art to overcome heresy with fire, the executioners would be the most learned doctors on earth.

The even larger difference between rich and poor makes the latter even worse off, and this violates the principle of mutual advantage.

Heaven, in the production of things, is sure to be bountiful to them, according to their qualities. Hence the tree that is flourishing, it nourishes, while that which is ready to fall, it overthrows.

Suffer no anxiety, for he who is a sufferer of anxiety becomes regardless of enjoyment of the world and the spirit, and contraction happens to his body and soul.

However long Jewish, Christian and Muslim theologians struggle to find multiple meanings in this text, the dominant seems to be this: Abraham's unquestioning willingness to heed gods command to sacrifice the thing he loved most is what qualified him to become the father of what are called still the Abrahamic faiths.

It is no one's privilege to despise another. It is only a hard-won right after long experience.

Now to Some it appears not at all worth while to follow out the endless divisions of Nature; and moreover a dangerous undertaking, without fruit and issue. As we can never reach, say they, the absolutely smallest grain of material bodies, never find their simplest compartments, since all magnitude loses itself, forwards and backwards, in infinitude; so likewise is it with the species of bodies and powers; here too one comes on new species, new combinations, new appearances, even to infinitude. These seem only to stop, continue they, when our diligence tires; and so it is spending precious time with idle contemplations and tedious enumerations; and this becomes at last a true delirium, a real vertigo over the horrid Deep.

Classical political economy nearly touches the true relation of things, without, however,consciously formulating it. This it cannot so long as it sticks in its bourgeois skin.

...happiness is not an ideal of reason but of imagination, resting solely on empirical grounds.

Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice.

It is a safe rule to apply that, when a mathematical or philosophical author writes with a misty profundity, he is talking nonsense.

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

The tangible source of exploitation disappears behind the façade of objective rationality.

To detach yourself elegantly from the world; to give contour and grace to sadness; a solitude in style; a walk that gives cadence to memories; stepping towards the intangible; with the breath in the trembling margins of things; the past reborn in the overflow of fragrances; the smell, through which we conquer time; the contour of the invisible things; the forms of the immaterial; to deepen yourself in the intangible; to touch the world airborne by smell; aerial dialogue and gliding dissolution; to bathe in your own reflecting fragmentation...

Chance seldom interferes with the wise man; his greatest and highest interests have been, are, and will be, directed by reason throughout his whole life.

Abstract terms (however useful they may be in argument) should be discarded in meditation, and the mind should be fixed on the particular and the concrete, that is, on the things themselves.
