...there is an even stronger reason why I am not afraid that scientists will inadvertently go and explain everything--it will never happen. ...for every question answered, a dozen newer ones are generated. And they are usually far more puzzling, more challenging than the prior problems. ... We will never have our flames extinguished by knowledge. The purpose of science is not to cure us of our sense of mystery and wonder, but to constantly reinvent and reinvigorate it. --Robert M. Sapolsky, in The Trouble with Testosterone (and other essays), p286.
