....every man did that which was right in his own eyes. Judges 21:25
"Temperate and considerate in his own life, Darwin may have 
sincerely
believed that his biology supported traditional morality. Nevertheless,
the internal logic of his theory did not allow any permanent foundation
for ethics other than the struggle to survive, and for that reason his
attempt to square a biological understanding of ethics with traditional
morality is ultimately unpersuasive... Darwin's account of the moral
sense ultimately implies the abolition of transcendent moral standards."
John West, Darwin Day in America, pp. 30-31
