man, not his corpse, but his soul. And so we live on the psychical deposits of our ancestry. Our souls consist of that material which once constituted other souls, as our bodies consist of the material which once constituted other bodies. A thought, it is to be replied, is never excreted from the mind and left behind. Only its existence is indicated by symbols, while itself is added to the eternal stock of the deathless mind. A thought is a spiritual product in the mind from an affection of the cerebral substance. A sentence is a symbol of a thought adapted to create in the contemplator just such a cerebral affection as that from which it sprang, and to deposit in his mind just such a spiritual product as that which it now denotes. Thus are we stimulated and instructed by the transmitted symbols of our ancestors' experiences, but not literally nourished by assimilation of their very psychical substance, as this remorseless prophet of death's ghastly idealism would have us believe. Still, in whatever aspect we regard it, one cannot but shudder before that terrible cineritious substance whose dynamic inhabitants are generated in the meeting of matter's messages with mind's forces, and sent forth in emblems to shake the souls of millions, revolutionize empires, and refashion the world.
Strauss employs an ingenious argument against the belief in a future life, an argument as harmless in reality as it is novel and formidable in appearance. "Whether the nerve spirit be considered as a dependent product, or as the producing principle of the organism, it ends at death: for, in the former case, it can no longer be produced when the organism perishes; in the latter case, that it ceases to sustain the organism is a proof that it has itself decayed."22 In this specious bit of special pleading, unwarranted postulates are assumed and much confusion of thought is displayed. It is covertly taken for granted that every thing seen in a given phenomenon is either product or producer; but something may be an accompanying part, involved in the conditions of the phenomenon, yet not in any way essentially dependent on it, and in fact surviving it. What does Strauss mean by "the nerve spirit"? Is there no mind behind it and above it, making use of it as a servant? Our present life is the result of an actual and regulated harmony of forces. Surely that harmony may end without implying the decay of any of its initial components, without implying the destruction of the central constituent of its intelligence. It is illegitimate logic, passing from pure ignorance to positive affirmation; a saltation of sophistry from a negative premise of blindness to all behind the organic life, to a dogmatic conclusion of denial that there is any thing behind the organic life.
A subtle and vigorous disbeliever has said, "The belief in immortality is not a correct expression of human nature, but rests solely on a misunderstanding of it. The real opinion of human nature is expressed in the universal sorrow and wailing over death." It is obvious to answer that both these expressions are true utterances of human nature. It grieves over the sadness of parting, the appalling change and decay, the close locked mystery of the unseen state. It rejoices in the solace and cheer of a sublime hope springing out of the manifold powerful promises within and without. Instead of contemning the idea of a heavenly futurity as an idle dream image of human longing, it were both devouter and more reasonable, from

that very causal basis of it, to revere it and confide in it as divinely pledged. All the thwarted powers and preparations and affections, too grand, too fine, too sacred, to meet their fit fulfilment here, are a claim for some holier and vaster sphere, a prophecy of a more exalted and serene existence, elsewhere. The unsatisfied and longing soul has created the doctrine of a future life, has it? Very good. If the soul has builded a house in heaven, flown up and made a nest in the breezy boughs of immortality, that house must have tenants, that nest must be occupied. The divinely implanted instincts do not provide and build for naught.
Certain considerations based on the resemblances of men and beasts, their asserted community of origin and fundamental unity of nature, have had great influence in leading to the denial of the immortality of the human soul. It is taken for granted that animals are totally mortal; and then, from the apparent correspondences of phenomena and fate between them and us, the inference is drawn that the cases are parallel throughout, and that our destiny, too, is annihilation. The course of thought on this subject has been extremely curious, illustrating, on the one hand, that "where our egotism begins, there the laws of logic break," and, on the other hand, that often when fancy gets scent of a theory the voice and lash of reason are futile to restrain it until the theory is run into the ground. Des Cartes, and after him Malebranche and a few other writers, gave no slight currency to the notion that brutes are mere machines, moved by prearranged influences and utterly destitute of intelligence, will, or consciousness. This scheme gave rise to many controversies, but has now passed into complete neglect.23 Of late years the tendency has been to assimilate instead of separating man and beast. Touching the outer sphere, we have Oken's homologies of the cranial vertebra. In regard to the inner sphere, we have a score of treatises, like Vogt's Pictures from Brute Life, affirming that there is no qualitative, but merely a quantitative, distinction between the human soul and the brute soul.24 Over this point the conflict is still thick and hot. But, however much of truth there may be in the doctrine of the ground identity of the soul of a man and the soul of a dog, the conclusion that man therefore perishes is a pure piece of sophistry. Such a monstrous assassination of the souls of the human race with the jaw bone of an ass may be legitimately avoided in either of two ways. It is as fair to argue the immortality of animals from their likeness to us, as our annihilation from our likeness to them. The psychological realm has been as much deepened in them by the researches of modern science as the physiological domain has been widened in us. As Agassiz says, we must not lose sight of the mental individuality of animals in an exclusive attention to the bodily side of their nature.25 A multitude of able thinkers have held the faith that animals have immaterial and deathless souls. Rightly considered, there is nothing in such a
