Here is an excerpt:
"Science is not a monument of received Truth but something that people do to look for truth.
That endeavor, which has transformed the world in the last few centuries, does indeed teach values. Those values, among others, are honesty, doubt, respect for evidence, openness, accountability and tolerance and indeed hunger for opposing points of view. These are the unabashedly pragmatic working principles that guide the buzzing, testing, poking, probing, argumentative, gossiping, gadgety, joking, dreaming and tendentious cloud of activity — the writer and biologist Lewis Thomas once likened it to an anthill — that is slowly and thoroughly penetrating every nook and cranny of the world.
Nobody appeared in a cloud of smoke and taught scientists these virtues. This behavior simply evolved because it worked.
It requires no metaphysical commitment to a God or any conception of human origin or nature to join in this game, just the hypothesis that nature can be interrogated and that nature is the final arbiter."
