Various, Popular Science Monthly (1908)
“ Is an affinity a person of the other sex just like ourselves in heredity, but with other defects, or is this affinity a person of other stock or race enclosed and harmonized by the influence of the same environment? The answer to these questions is to be found not in biological studies of germ cells, but in psychology and physiology. An affinity is a strong dominating form of attachment which suppresses the ordinary thought processes and puts in their place many unique emotions and illusions. ”
