Excerpt from Contemporary Schools of Psychology In the present age of progressive thinking - no doubt one Of the recurring periods of illumination that the world has gone through, and perhaps the greatest Of them - a large role is being played by the advance Of science and by the increasing public acquaintance with science. The new light comes in part from the physical, biological, and medical sciences, but no small measure of it comes from the sciences that deal with human behavior; Where the darkness has been densest, illumination finds most to reveal. Research on intelligence and motivation, on heredity and environment, are gradually clarifying what have always been matters of conflicting Opinion. And besides this slow dawn Of psychological knowledge, we are exposed to the blinding flashes of psychoanalysis, behaviorism, and other schools Of psychology, some of them little known as yet to the interested public. The light emitted by these radical schools, though still far from steady and serene, does altord revealing glimpses of the unknown.
