THE PRINCIPLES OF TRAINING

It is a long time since naturalists¹ and philosophers maintained the doctrine² that animals, being controlled by instinct, were quite incapable³ of comprehending new ideas, and of acquiring and memorizing novel things which they have been taught to do by man.

Many reflective men now believe that the mind of an animal differs from the human intellect only in degree. The extent of this difference, however, remains⁴ a question, and one on which close observation of domestic animals, and more particularly of wild animals trained for public amusement, is calculated to throw a great deal of light.

Through a study of wild animals in their native haunts there may be learned what progress each has made in adapting itself to183 the natural conditions of its life; but the study of trained animals, placed under new conditions and influences, will show whether these are capable of further or, at any rate, divergent advancement⁵ intellectually, and give some hint of the probable limit of this progress. It may then be seen to what extent the animal trainer has gone in his development of brute⁶ intellect, and that that development has come about under conditions not entirely⁷ dissimilar to those observed in the advancement of the intellect of the higher species of animals.

It should be noted⁸, first, that “taming” and “training” are two different words expressing two distinct ideas. “Taming” is merely inducing an animal to abandon its natural fierce disposition⁹ so far as to come under human control and be more or less sociable
