The first scientific postulate is the objectivity of nature: nature does not have any intention or goal. - Jacques Monod

There is in science, however, quite a gap between belief and certainty. But would one ever have the patience to wait and to establish the certainty if the inner conviction were not already there?

What I consider completely sterile is the attitude, for instance, of Bertalanffy who is going around and jumping around for years saying that all the analytical science and molecular biology doesn’t really get to interesting results; let’s talk in terms of general systems theory ... there cannot be anything such as general systems theory, it’s impossible. Or, if it existed, it would be meaningless.

If [the emergence of the human species] was unique, as may perhaps have been the appearance of life itself, then before it did appear its chances of doing so were infinitely slender. The universe was not pregnant with life nor the biosphere with man. Our number came up in the Monte Carlo game.
