But Actually ...
Not only has Darwin's family denied the story, but there's no reason to believe it's true.
Keep in mind that Darwin started out religious and turned less so as he got older, eventually becoming an agnostic, as he was at the time of his death. His last words were "I am not the least afraid to die." Also remember that Darwin's wife, Emma, was religious herself and would have delighted in her husband's conversion, yet she never mentioned anything of the sort. So where did the rumor come from? Well, let's put it this way: It wasn't exactly an unbiased source.
"And then Darwin was all 'God's the bomb, yo! Let's dunk some s**t.' And then we totally dunked some s**t."
The story came from an evangelist named Lady Hope, who claimed that Darwin recanted his beliefs while she was visiting him. First, even among evangelists, Hope, whose real name was Elizabeth Cotton, wasn't well-trusted. Second, while she published more than 30 books filled with evangelistic themes and personal anecdotes, she never mentioned the Darwin story until 1915, 33 years after the man's death. According to her own telling, Darwin urged her to spread the word of Jesus among his tenants, servants, and neighbors ... yet not a single person confirmed that she was even there.
Who could forget that lovely hat, or those empty, soulless eyes?
