Bernard Shaw once put forward the theory that this planet is the lunatic asylum for the whole solar system. Nobody took his theory seriously, and everybody complimented him on his wit and humour. I, however, have long held a kindred theory that the human race is evolving from insanity to sanity and that except in a few rare individuals--the sages--it is far from the goal. The dangers of expressing this view are such that I have hitherto held my tongue along with the view itself. To question the mental status of so many millions of people would have been an open invitation to be incarcerated without delay in an institution for the mad. But I am at last emboldened to say all this because a scientist, Dr. Estabrooks, a professor of psychology at Colgate University, has pronounced a similar judgement and even dared to put it into print.
