To some extent that attitude is excused, not only by the mistakes which in a new and complex science must inevitably be made even by painstaking students, but also by the rash and extravagant proposals of irresponsible and eccentric persons claiming without warrant to speak in the name of eugenics. Two thousand years ago the wild excesses of some early Christians furnished an excuse for the ancient world to view Christianity with contempt, although the extreme absence of such excesses has furnished still better ground for the modern world to maintain the same view.
