In man, there is no longer anything of the animal but his body, and the passions which are the joint product of his body and of the instinct of self-preservation inherent in matter. It cannot, there-fore, be said that such and such a man is the incarnation of such and such an animal; and consequently the doctrine of the metempsychosis, as commonly understood, is not true."
