The mistake of most reasoners on the subject, Winslow and Hufeland more especially, consists in this, that they fix their attention exclusively upon the final moments of dissolution. But the act of dying may be in disease, as we know it to be in many modes of violence, impalement, for example, or crucifixion, very variously protracted and progressive. “Insensibly as we enter life,” says Hufeland, “equally insensibly do we leave it. Man can have no sensation of dying.” Here the insensibility of _death completed_, that is, of _the dead body_, is strangely predicated of the moribund while still living. This transitive condition, to use the graphic language of the Southern writer whom we have already more than once quoted, is “a terra incognita, where vitality, extinguished in some tissues, smouldering in others, and disappearing gradually from all, resembles the region of a volcano, whose eruptions subsiding, leave the surface covered with cinders and ashes, concealing the rents and lesions which have on all sides scarred and disfigured the face of nature.” Besides this, we have no right to assume, as Hufeland has here done, the insensibility of the child at birth. It is subject to disease before birth; as soon as it draws a breath, it utters loud cries and sobs. To pronounce all its actions “mechanical, instinctive, necessary, automatic,” in fact, is a very easy solution of the question; but I think neither rational nor conclusive. If you prick it or burn it, you regard its cries as proving sensibility to pain; but on the application of air to its delicate and hitherto protected skin, and the distension of its hitherto quiet lung, the same cry, you say, is mechanical and inexpressive. So Leibnitz explained, to his own satisfaction, the struggles and moans of the lower animals as automatic, being embarrassed with metaphysical and moral difficulties on the score of their intelligence and liability to suffering. But no one now espouses his theory, and we must accept, whether we can explain them or not, the facts that the lower animals are liable to pain during their entire existence, and that the heritage of their master is, from and during birth to the last moment of languishing vitality, a sad legacy of wo and suffering.
