What is the meaning of life?

As Albert Camus states in 'Myth of Sisyphus' there is just one philosophical problem and that is suicide. Judging whether life is or is not worth living amounts to answering the most fundamental question of philosophy. All other concerns are merely games to pass the time.

Lemme try to bravely confront the question. No, don't talk god and religion and salvation to me. A world that can be explained even with bad reasons is a familiar world, Camus says. In a universe suddenly divested of lights and illusions, man feels an alien, a stranger.

So, do I have a path to proceed, rationally and logically, following the path of reason and not that of belief?

So, what is happening now?

Billions of neurons are firing in my brain and I am able to feel what I am feeling and think what I am thinking. My self-knowledge is shaped by the emotional control centers in the hypothalamic-limbic system of the brain. These centers flood my consciousness with all the emotions. What made the hypothalamic and limbic systems? They evolved by natural selection. That simple biological statement is the key to all answers.

I pity Camus. Truth is more worse than he comprehended. The hypothalamic-limbic system automatically denies logical reductions to suicide in most of us by countering it with feelings of guilt and altruism. We are machines made to survive.

In evolutionary time, the individual organism counts for almost nothing. In a Darwinist sense the organism does not live for itself. Its primary function is not even to reproduce other organisms, it reproduces genes and it serves as their temporary carrier. Each organism generated by sexual reproduction is a unique accidental subset of all the genes constituting the species.

E.O. Wilson in 'Sociobiology - a new synthesis' elaborates - Natural Selection is the process whereby certain genes gain representation in the following generations superior to that of other genes at the same chromosome positions. In the process of natural selection, then any device that can insert a higher proportion of certain genes into subsequent generations will come to characterize the species. One class of such devices promotes prolonged individual survival. Another promotes superior mating performance and care of resulting offspring. As more complex social behaviour by the organism is added to the genes' techniques of replicating themselves, altruism becomes increasingly prevalent and appears in exaggerated forms.
