CHAPTER THE ELEVENTH.
WHAT IS AN ANIMAL?—THE SOULS OF ANIMALS.—MIGRATIONS OF SOULS THROUGH THE BODIES OF ANIMALS.
HITHERTO we have left animals out of our plan, although, owing to their immense number, and their influence upon the places which they inhabit, they play a highly important part in the world. It is now time to define the place in nature which our system assigns to them.
Have animals souls? Yes, in our belief, animals have souls; but among animals of all classes the soul is far from being endowed with an equal degree of activity. The activity of the soul is different in the crocodile and in the dog, in the eagle and in the grasshopper. In inferior animals, zoophytes and mollusca, the soul exists only in the condition of a germ. This germ develops itself, and becomes amplified according to the elevation of animals in the series of organic perfection. The sponge and the coral are zoophytes (animal plants). In these beings, the characteristics of animality, although they exist very positively, are obscure and hardly discernible. Voluntary motion, which is the distinctive characteristic formerly demanded for animals, is wanting in them; they are motionless, like the plants. Nevertheless, their nutrition is the same as that of animals, therefore they belong to the animal world. We cannot, however, grant to them a complete soul, but only the germ, the originating point of a soul. Among mollusca (such as marine and land shells, the oyster, the snail, &c.), the motions and the conduct of life are dictated by the will, and that suffices, in our belief, to reveal their possession of a soul, imperfect and very elementary, but certainly existent. Among articulated animals, the insects especially, will, sensibility, acts which denote reason, deliberation, and action resulting from deliberation, are numerous, and recurrent at every moment. They denote intelligence already active.
The smallness of the bodies of these animals is not an argument to be used against the fact of their intelligence. In nature nothing is great, and nothing is little; the monstrous whale and the invisible gnat are equal in the presence of its laws; both one and the other have received as their inheritance the degree of intelligence which is suitable to its need, and it is not by the scale of grandeur that we must measure the degrees of mind among living creatures. Every one is familiar with the prodigies of intelligence performed by associated bees, and by the ants, in their camps and hills. The habits of these two species of insects, which have been studied and expounded only in our age, fill us with wonder, almost with awe. But the bees and the ants do not constitute an exception among the insect class. It is very probable that in the entire class intelligence exists to the same degree as in bees and ants, for we do not see why two species of hymenopterous insects should exclusively possess this privilege, to the exclusion of other species of the same order, and all the other orders of the insect class. The fact is, that the bee has been studied profoundly, because that insect is an object of agricultural industry, and that, in consequence, it was for man's interest to understand its customs. This accounts for the successful surmounting of the difficulties attendant on the study of bees.
We may add, that the observer to whom our knowledge of bees is due, Pierre Huber, of Geneva, who published his fine works at the end of the last century, was blind, and that he was obliged to have recourse for all his observations to the eyes of an illiterate servant, François Burnens, which is a proof that this kind of study was not inordinately difficult.
The habits of other species of insects, still unknown to us, must, according to this, conceal marvels quite as great as those which the Hubers have revealed in the case of bees and ants.
Let us conclude that insects have souls, since intelligence is a faculty of the soul.
We may apply the same reasoning to fishes, reptiles, and birds. In these three classes of animals intelligence progresses towards perfection, the faculty of reason is manifest, and the degree of intelligence seems to march at a progressive rate from the fish to the reptile, and from the reptile to the bird.
