DEGREE OF PERFECTION IN INDUSTRY INDEPENDENT OF ZOOLOGICAL SUPERIORITY MENTAL FACULTIES OF THE LOWER ANIMALS OF LIKE NATURE TO MAN’S.

Degree of perfection in industry independent of zoological superiority. As the result of our study we see the fundamental industries of Man dispersed throughout the animal kingdom, though not, indeed, all of them, nor the more subtle, which were only born yesterday. We may remark the extent to which intellectual manifestations of this sort are independent of the more or less elevated rank assigned to species in zoological classification. The latter, as it should be, brings together or separates beings according to their physical character. But intelligence does not depend on the whole body; its superior or inferior development is related to a certain corresponding complexity in the surface, volume, and histologic structure of the nervous centres.

It happens with the cerebral as with the other functions. An animal’s superiority is not exhibited in all his organs nor in all his qualities; it results from a certain grouping of characters in which there may be weak points. The highest in organisation are not necessarily the swiftest or the strongest, any more than they are necessarily the most intelligent. It may happen; it happens in the case of Man; but it as easily fails to happen. In organisation the Horse is nearer to Man than the Ant; but it is far otherwise as regards intellectual development.

For this reason, when following the progress of any industry, I have taken my examples first in one group, then in another far-removed group, to return afterwards to the first. There are not, and cannot be, bonds between a solitary function of the being and its place in classification a place which has been determined by the form of all the organs, without even taking into account their methods of activity.

Comparative anatomy has long since removed the barriers, once thought impassable, raised by human pride between Man and the other animals. Our bodies do not differ from theirs; and moreover, such glimpses as we are able to obtain allow us to conclude that their psychic faculties are of the same nature as our own. Man in his evolution introduces no new factor.

The industries in which the talents of animals are exercised demonstrate that, under the influence of the same environment, animals have reacted in the same manner as Man, and have formed the same combinations to protect themselves from cold or heat, to defend themselves against the attacks of enemies, and to ensure sufficient provision of food during those hard seasons of the year when the earth does not yield in abundance.

It must only be added, to avoid falling into exaggeration, that Man excels in all the arts, of which only scattered rudiments are found among the other animals; and we may safeguard our pride by affirming that we need not fear comparison. If our intelligence is not essentially different from that of animals, we have the satisfaction of knowing that it is much superior to theirs.
