Over the centuries, we've moved on from Scripture to accumulate precepts of ethical, legal and moral philosophy. We've evolved a liberal consensus of what we regard as underpinnings of decent society, such as the idea that we don't approve of slavery or discrimination on the grounds of race or sex, that we respect free speech and the rights of the individual. All of these things that have become second nature to our morals today owe very little to religion, and mostly have been won in opposition to the teeth of religion.
Richard DawkinsSuch is the breathtaking speciesism of our Christian-inspired attitudes, the abortion of a single human zygote can arouse more moral solicitude and righteous indignation than the vivasection of any number of intelligent adult chimpanzees! The only reason we can be comfortable with such a double standard is that the intermediates between humans and chimps are all dead.
Richard DawkinsEven if not a single fossil has ever been found, the evidence from surviving animals would still overwhelmingly force the conclusion that Darwin was right.
