Biological Drive Quotes

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.

All nature's creatures join to express nature's purpose. Somewhere in their mounting and mating, rutting and butting is the very secret of nature itself.

Sex doesn't have to be taught. It's something most of us are born with.

Sex is not only the basis of life, it is the reason for life.

Sex is the great equalizer.

Unless we cut the world population there is no way to avoid violence. People are hungry, people are starving, dying. When somebody is hungry he is going to steal. When somebody is dying, what does he care if he kills somebody else and gets money to survive? - because lust for life is the basis of all biological growth. A man can do anything to survive.

Our brain, our body, craves fat. We cannot help it. That's why a kid will eat a hot dog quicker than a piece of broccoli.

The drive to propagate our race has also propagated a lot of other things

Disassemble the cells of a sponge (by passing them through a sieve, for instance), then dump them into a solution, and they will find their way back together and build themselves into a sponge again. You can do this to them over and over, and they will doggedly reassemble because, like you and me and every other living thing, they have one overwhelming impulse: to continue to be.

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.

There is in every organism, at whatever level, an underlying flow of movement toward constructive fulfillment of its inherent possibilities.

From an evolutionary point of view, sex is really just a reward mechanism to encourage us to pass on our genetic material.

Then, of course, through the umbilical link we all tumble backwards down the spiralling DNA staircase to one common ancestor in Africa, and before that some bunch of curious monkeys. Down and down we go unto the sea, unto the dust, the single cellular dust. What impulse drove one cell to become two? What yearning pulled the fish on to the land? What caused apes to walk upright? Some invisible magnetic pull. Is there a difference between attraction and intention? Where is evolution taking us?

All of us from fertile egg to embryo to corpse, are exactly that: warm, wet, furry animals compelled by the sexuality of our forefathers and foremothers to be, either directly or indirectly, our own exciting and excitable, provocative and provocable selves.

The act of sex, gratifying as it may be, is God's joke on humanity. It is man's last desperate stand at superintendency.

Appetite, n. An instinct thoughtfully implanted by Providence as a solution to the labor question.

I have always had this basic biological question in terms of evolution, if the drive to evolution is to like survive. An organism that survives well, there is really no need for consciousness in there.

Maternal instinct, merely as an instinct, is unworthy of our superstitious reverence.

In all warm-blooded creatures, which are the highest evolved and have feelings, passions and emotions, which reach outward into the world with desire, which may be said to really live in the fuller meaning of the term and not merely vegetate - in all such creatures, the currents of the desire body flow outward from the liver.

People ... have tried to evoke God or devil to justify them in what their glands insisted upon.

It stands to reason that we love chocolate cake because it is sweet. Guys go for girls like this because they are sexy. We adore babies because they're so cute. And, of course, we are amused by jokes because they are funny. This is all backwards. It is. And Darwin shows us why.

If combat means living in a ditch, females have biological problems staying in a ditch for 30 days because they get infections... Males are biologically driven to go out and hunt giraffes.
