ABSTRACT
One of the gravest charges ever made against science is that biology has now put it into our power to corrupt both the body and the mind of man. The mischief that science may do grows just as often out of trying to do good – as, for example, improving the yield of soil is intended to do good – as out of actions intended to be destructive. Everybody takes it for granted, because it is so obviously true, that a married couple will have children of very different kinds and constitutions on different occasions. Eugenics is traditionally subdivided into positive and negative eugenics. Positive eugenics has to do with attempts to improve human beings by genetic policies, particularly policies founded upon selective or directed breeding. Negative eugenics is a more manageable and understandable enterprise than positive eugenics.
