Darwin was described by his friend and champion, Thomas Huxley, as a symbol . But what did he symbolize? In Wilson s portrait, both sympathetic and critical, Darwin was two men. On the one hand, he was a naturalist of genius, a patient and precise collector and curator who greatly expanded the possibilities of taxonomy and geology. On the other hand, Darwin, a seemingly diffident man who appeared gentle and even lazy, hid a burning ambition to be a universal genius. He longed to have a theory which explained everything.

But was Darwin s 1859 master work, On the Origin of Species, really what it seemed, a work about natural history? Or was it in fact a consolation myth for the Victorian middle classes, reassuring them that the selfishness and indifference to the poor were part of nature s grand plan?
