Now, what can be expected of a dog or a cat, whose mental processes have been adjusted by inheritance and experience to life in the fields and jungles, when placed in a box, utterly hungry, to study mechanical contrivances? It is manifest that if the brain of a dog or a cat would become adjusted to the radically unfamiliar steps necessary to release it from such a radically unfamiliar environment, that adjustment could only come by extremely slow degrees. Voluntary perception is almost beyond the limits of expectation, and the leading of the animal through the necessary steps would have to be repeated time after time before the impressions upon its brain would reach any degree of permanence, especially as its brain would be lacking in attention, and the repeated handling be an annoyance to it. But that by such tutelage the animals, or a proportion of them, arrived at a knowledge of the means necessary to escape from the box is shown by Dr. Thorndike himself. "If one repeats the process, keeps putting the cat back into the box after each success, the amount of useless action gradually decreases, the right movement is made sooner and sooner, until finally it is done as soon as the cat is put in." But he says: "This sort of a history is not the history of a reasoning animal. It is the history of an animal who meets a certain situation with a lot of instinctive acts.... Little by little the one act becomes more and more likely to be done in that situation, while the others slowly vanish. This history represents the wearing smooth of a path in the brain, not the decisions of a rational consciousness." Wherein, however, does this differ from the manner in which hundreds of clerks in offices finally learn routine work and mechanically go through the motions necessary to its performance? Do not the actions of thousands of laborers in field and factory seem to proceed from a wearing smooth of a path in the brain, rather than from rational consciousness? Yet they can not be said to be devoid of reason. Is not a great proportion of the daily actions of any one of us gone through from force of habit, almost by instinct? The word reason does not apply alone to the mental processes of a Helmholtz, but to the co-ordination, however slight, of relations that result in definite action even of a humble organism. Herbert Spencer has clearly shown that instinct and reason differ in degree and not in kind.
