ABSTRACT
The assertion is often made that the Psychology of to-day tends to emphasize the individual and his differences rather than the universal and alike. In adopting an attitude of experimental detachment Psychologists would appear to be approaching more nearly to the methods of Biology and even to those of the physical sciences. It is possibly true that along these lines only can the claims of Psychology to recognition as an exact science be established. If, in the laboratory, the psychologist can measure and correlate, and devise a law which will fit the measurements, and on the basis of which further predictions can be made, then he will receive at the hands of scientists the recognition of equality. Until that time he is apt to be looked upon with suspicion by the chemists and physicists as one who seeks on the one hand to ally himself with pure speculative philosophy, and on the other to claim for his subject a position among the exact sciences.
