Richard Dawkins Quotes

An intelligent couple can read their Darwin and know that the ultimate reason for their sexual urges is procreation. They know that the woman cannot conceive because she is on the pill. Yet they find that their sexual desire is in no way diminished by the knowledge. Sexual desire is sexual desire and its force, in an individual's psychology, is independent of the ultimate Darwinian pressure that drove it. It is a strong urge which exists independently of its ultimate rationale.

The human brain became large by natural selection (who knows why, but presumably for good cause). Yet surely most "things" now done by our brains, and essential both to our cultures and to our very survival, are epiphenomena of the computing power of this machine, not genetically grounded Darwinian entities created specifically by natural selection for their current function.

We are all ruled in what we do by impulses; and these impulses are so organized that our actions in general serve for our self preservation and that of the race.

The urgency to mate persists in all people as in all other mammals because of the evolutionary drive to continue the species, the inborn imperative for genes to reproduce and hormonal differences that evolved over millions of years.

U.K. psychologist Daniel Nettle thinks of happiness as a carrot on a stick, designed by evolution to show the right way, and also designed so that we will never permanently reach it. We likely would just sit around and eat sweet and fatty foods all day, and that is simply not in the interest of evolution.

Retaliation is related to nature and instinct, not to law. Law, by definition, cannot obey the same rules as nature.

I have an odd theory on happiness, and it bothers people. My general theory is that happiness is a reward for an animal doing what it should be doing. So if a horse runs, it feels happy. Or if you are too thin, you can't be happy, because evolution wants you to be tense and anxious, trying to wake up in the morning looking for food.

Evolutionarily speaking, there is seldom any mystery in why we seek the goals we seek — why, for example, people would rather make love with an attractive partner than get a slap on the belly with a wet fish.

It is almost as if the human brain were specifically designed to misunderstand Darwinism, and to find it hard to believe

Nature is reckless of the individual. When she has points to carry, she carries them.

Sex just as a drive, as a hormonal drive, is not very interesting.

Animals are molded by natural forces they do not comprehend. To their minds there is no past and no future. There is only the everlasting present of a single generation, its trails in the forest, its hidden pathways in the the air and in the sea. There is nothing in the Universe more alone than Man. He has entered into the strange world of history.

There's something about the human brain, that it actually has a predilection towards negativity, which served us really well when we lived in an environment that was very threatening.

These capacities for randomness may have been amplified into human creativity through sexual and social selection.

In proportion to our body mass, our brain is three times as large as that of our nearest relatives. This huge organ is dangerous and painful to give birth to, expensive to build and, in a resting human, uses about 20 per cent of the body's energy even though it is just 2 per cent of the body's weight. There must be some reason for all this evolutionary expense.

We have become too civilized to grasp the obvious. For the truth is very simple. To survive you often have to fight, and to fight you have to dirty yourself. War is evil, and it is often the lesser evil. Those who take the sword perish by the sword, and those who don't take the sword perish by smelly diseases.

Secondly, man sins against nature when he goes against his generic nature, that is to say, his animal nature. Now, it is evident that, in accord with natural order, the union of the sexes among animals is ordered towards conception. From this it follows that every sexual intercourse that cannot lead to conception is opposed to man's animal nature.

The genes hold culture on a leash. The leash is very long, but inevitably values will be constrained in accordance with their effects on the human gene pool. The brain is a product of evolution. Human behavior-like the deepest capacities for emotional respone which drive and guide it-is the circuitous technique by which human genetic material has been and will be kept intact.

MAN IS FUNDAMENTALLY AN ANIMAL. Animals, as distinct from man, are not machine-like, not sadistic; their societies, within the same species, are incomparably more peaceful than those of man. The basic question, then is: What has made the animal, man, degenerate into a machine?

The rule of thumb based into the brain by natural selection would not have been, Be nice to your kin and be nice to potential reciprocators. It would have been, Be nice to everybody, because everybody would have been included.

. . . by natural selection our mind has adapted itself to the conditions of the external world. It has adopted the geometry most advantageous to the species or, in other words, the most convenient. Geometry is not true, it is advantageous.

I think it's one of the most natural things for any human to do is to be able to run because it's that flight or fight reaction you have. You either fight or you run away. It's just a natural way for us to move.

In nature, creatures never ended the lives of others except to survive. To women, abortion was self-defense and preservation of the species. Abortion was not a fancy borne out of the female mind. Abortion was instinct beyond ideas. Abortion was fear (the cat that devours its litter when a predator nears).

I don't think I was constructed to be monogamous. I don't think it's the nature of any man to be monogamous. Men are propelled by genetically ordained impulses over which they have no control to distribute their seed into as many females as possible.

The human brain, then, is the most complicated organization of matter that we know.
