[491] Dr. McCosh is accordingly only logical when he sinks similarity in what he calls the Law of Correlation, according to which, when we have discovered a relation between things, the idea of one tends to bring up the others, (Psychology, the Cognitive Powers, p. 130). The relations mentioned by this author are Identity, Whole and Parts, Resemblance, Space, Time, Quantity, Active Property, and Cause and Effect. If perceived relations among objects are to be treated as grounds for their appearance before the mind, similarity has of course no right to an exclusive, or even to a predominant, place.
