Evolution has encountered no intellectual trouble; no new arguments have been offered. Creationism is a home-grown phenomenon of American sociocultural history-a splinter movement ... who believe that every word in the Bible must be literally true, whatever such a claim might mean.

In what I like to call the Great Asymmetry, every spectacular incident of evil will be balanced by 10,000 acts of kindness, too often unnoted and invisible.
