What proofs other than negative have we that the animal is without a surviving, if not immortal, soul? On strictly scientific grounds we can adduce as many arguments pro as contra. To express it clearer, neither man nor animal can offer either proof or disproof of the survival of their souls after death. And from the point of view of scientific experience, it is impossible to bring that which has no objective existence under the cognizance of any exact law of science.
