From the wonderful Edge web page. On being asked what he believed in but could not prove, Tor Nooretranders wrote:
I believe in belief—or rather: I have faith in having faith. Yet, I am an atheist (or a "bright" as some would have it). How can that be?
It is important to have faith, but not necessarily in God. Faith is important far outside the realm of religion: having faith in other people, in oneself, in the world, in the existence of truth, justice and beauty. There is a continuum of faith, from the basic everyday trust in others to the grand devotion to divine entities.
Recent discoveries in behavioural sciences, such as experimental economics and game theory, shows that it is a common human attitude towards the world to have faith. It is vital in human interactions; and it is no coincidence that the importance of anchoring behaviour in riskful trust is stressed in worlds as far apart as Søren Kierkegaard's existentialist christianity and modern theories of bargaining behaviour in economic interactions. Both stress the importance of the inner, subjective conviction as the basis for actions, the feeling of an inner glow.
One could say that modern behavioral science is re-discovering the importance of faith that has been known to religions for a long time. And I would argue that this re-discovery shows us that the activity of having faith can be decoupled from the belief in divine entities.
So here is what I have faith in: We have a hand backing us, not as a divine foresight or control, but in the very simple and concrete sense that we are all survivors. We are all the result of a very long line of survivors who survived long enough to have offspring. Amoeba, rodents and mammals. We can therefore have confidence that we are experts in survival. We have a wisdom inside, inherited from millions of generations of animals and humans, a knowledge of how to go about life. That does not in any way imply foresight or planning ahead on our behalf. It only implies that we have a reason to trust out ability to deal with whatever challenges we meet. We have inherited such an ability.
Therefore, we can trust each other, ourselves and life itself. We have no guarantee or promises for eternal life, not at all. The enigma of death is still there, ineradicable.
But we a reason to have confidence in ourselves. The basic fact that we are still here—despite snakes, stupidity and nuclear weapons—gives us reason to have confidence in ourselves and each other, to trust others and to trust life. To have faith.
Because we are here, we have reason for having faith in having faith.
