Christianity Today has a review by Edward Oakes of Richard Weikart's new book From Darwin to Hitler: Evolutionary Ethics, Eugenics, and Racism in Germany the thesis of which is that Darwin's ideas led pretty much directly to the holocaust. It's a thesis guaranteed to produce howls of protest from Darwinians, but one which Oakes' review certainly confirms:
According to the myths of standard historiography, Darwin confined himself strictly to matters biological-even in The Descent of Man, when he finally came, late in life, to apply his theory to man's place in the evolutionary tree. So whatever damage came to the poor and downtrodden from Darwin's theory is due to others, above all Herbert Spencer. Here, in Spencer, can be found the villain of the piece: that second-rate thinker ruined a perfectly good biological theory by hijacking it for cutthroat capitalism, contempt for the poor, laissez-faire lassitude about social legislation, and so forth. Spencer, the claim goes, was the first to transpose ethics into evolutionary terms, defining as good whatever promoted the "progress" of evolution and as bad whatever hindered it.
Unfortunately for Darwin's own reputation, this thesis does not bear scrutiny. Spencer might well have been the first to coin the phrase "survival of the fittest." But Darwin enthusiastically adopted it in the 6th edition of his Origin of Species as a substitute term for "natural selection." Nor did he ever demur when other advocates of evolution's social application came pleading their case. Karl Marx asked if he might dedicate Das Kapital to Darwin, which request Darwin declined only because he did not want to offend the religious sensibilities of his deeply Christian wife.
Nor were Darwin's own musings on the social implications of his theory limited to private correspondence. In one particularly chilling passage in Descent of Man he asserted, "At some future period, not very distant as measured by centuries, the civilized races of man will almost certainly exterminate and replace throughout the world the savage races." Even more ominously, this insouciantly expressed sentiment cannot be regarded as an illegitimate conclusion from the earlier and more reliable Origin of Species.
In a passage historians often cite to prove that at the time of the Origin Darwin was still struggling to maintain his belief in God, Darwin actually, if unwittingly, promulgated the charter for all later social Darwinists: "Let the strongest live and the weakest die.... Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows." In effect, this passage turns Christian theodicy on its head and gives St. Paul's line "Death is swallowed up in victory" a total reversal of meaning. Victory now belongs only to the fittest.
Don't miss Oakes' review. It's lengthy, but it's chock full of important information establishing the link between Darwin and the social Darwinists and through them to Nietzsche and ultimately the Nazis. Every twentieth century Western calamity seems traceable to some 18th or 19th century philosophical enthusiasm, and the Nazis' "final solution" is no exception.
