Jacques Monod's story has had so much success, especially among scientists. This fits the world-picture acquired by very many people in the course of a scientific education, an education which trains them in scientific thinking, and greatly exaggerates the precision possible to it. He declares that science is indeed the only field where thought is possible. Everything else must be left to choice: not reasonable choice, but choice in the Existentialist sense of a blind, inarticulate act of will. No special standing attaches either to the casino story or to the choice of a particular time-span. Steven Weinberg's choice of a very long span is useful enough in correcting the escalator model. It may be true that, as Weinberg says, 'it is almost irresistible for humans to believe that we have some special relation to the universe.'
