“For secular thinkers, the continuing vitality of religion calls into question the belief that history underpins their values. To be sure, there is disagreement as to the nature of these values.

Never well founded, this assumption is today clearly unreasonable. So, not for the first time, secular thinkers look to science for a foundation for their values.”
