Science regards man as an aggregation of atoms temporarily united by a mysterious force called the life-principle. To the materialist the only difference between a living and a dead body is, that in the one case that force is active, in the other latent. When it is extinct or entirely latent, the molecules obey a superior attraction, which draws them asunder and scatters them through space. This dispersion must be death, if it is possible to conceive such a thing as death where the very molecules of the dead body manifest an intense vital energy.
