The sufferings of animals are indeed a theme for man to reflect upon; and I, for my part, can not concur with him who would regard this as a topic unworthy of his thoughts, and expel from the human bosom all sympathy with the animal creation. The consideration, however, of this subject, naturally enough gives rise to the question as to the soul of animals. Now, it certainly would do no discredit to philosophy, if it should succeed in giving a satisfactory answer to this question, and enable us to follow a middle course; as remote from the exaggerated assumptions of ancient nations with regard to animal existence, on the one hand, as on the other, from the unfeeling conclusions of modern science, which refuses to regard or to sympathize with any pains, and absolutely is unable to conceive the sufferings of any being which does not possess the character of rationality exactly in the same manner and degree as man. As greatly, on the other side, does the Hindoo theology err. Its dogma of the metempsychosis not only ascribes an immortal soul to animals, but it also further teaches that human souls are imprisoned in animal bodies, as the penalty of a guilt incurred in a previous state of existence. Beautiful, however, as is the compassionate sympathy with the sufferings of the brute creation, which this theory has occasioned, and confirmed by the sanction of a religious duty, still the assumption on which it is founded is wholly arbitrary, and the extension of the immortality of the soul to these creatures of our globe is an unwarrantable exaggeration, and has no foundation in observed phenomena. Moreover, the hypothesis of such a migratory state of departed souls is inconsistent with every notion of the divine government of the world; inasmuch as such a temporary punishment can produce no salutary effect, either of purification or of preparation, and consequently would be wholly motiveless and absurd. Very questionable, moreover, does it seem, whether, with propriety, an individual soul can be attributed to animals. With those that are most closely domesticated with man, there does undoubtedly arise, as it were, by a sort of mental contagion, the appearance of individuality and difference of character, just as the artistic structures of certain species form a kind of analogy to human reason, and as the melodious intonations and feelings of some others seemed to me entitled, in a similar sense, to be termed reverberations of fancy. In all those kinds, however, which remain undisturbed in their natural state, the whole species possesses the same character, and have, consequently, the same common soul.[30] The species itself is only an individual; and, consequently, the several species must be considered as so many living forms of the general organic force of animated nature, since an immortality of individual souls can, in the case of animals, neither be assumed nor allowed to be assumable.
