The animal fulfils, as far as he can, the same sort of function; he has his environment, both physical and social; he works under the same laws of growth which man also obeys; his mind exhibits substantially the same phenomena which the human mind exhibits in its early stages in the child.

All this means that the animal has as good right to recognition, as a mind-bearing creature, so to speak, as the child; and if we exclude him we should also exclude the child.

Further, this also means--what is more important for the science of psychology--that the development of the mind in its early stages and in certain of its directions of progress is revealed most adequately in the animals.
_Animal Instinct._--Turning to the animals, the first thing to strike us is the remarkable series of so-called animal Instincts.

Everybody knows what animal instincts are like; it is only necessary to go to a zooelogical garden to see them in operation on a large scale.

Take the house cat and follow her through the life of a single day, observing her actions.
