Starting at around 10:00 in this interview, Dawkins illuminates the CBC interviewer on the subject of right behaviour by claiming that to help a homeless person is the misfiring of a Darwinian impulse.

From Dawkins’ perspective this is a logical, if bleak, conclusion. He rather lets his side down, though, by backpedalling: he reassures the interviewer that this does in no way belittle attempts to help those less fortunate than ourselves.

Rubbish. According to Dawkins’ Darwinian lights, “belittle” is a moral evaluation and has no meaning in the context of pitiless, indifferent evolution.
