Because we’re seeing so many stories about bioethics, I’ve been trying to learn a bit more the field of thought. I recently read G.K. Chesterton’s “Eugenics and Other Evils: An Argument Against the Scientifically Organized State.” It’s a collection of essays written in the 1920s at the height of the eugenics movement. One of the things I found so interesting about the book is that if it were read in the 1920s, one would think that Chesterton was fighting a lonely and losing battle. But a few more decades of eugenics — punctuated by the Nazi embrace, of course — and people began questioning and rejecting it.
