It has likewise been objected that we do not sufficiently allow for the possibility that the present universe may be infinite, and that thus it might last for ever and continue, although spasmodically, to be the residence of living beings even in spite of the constant degradation of its energy. Unquestionably we cannot prove that the present visible universe is not infinite; this we have acknowledged in our work. But our chief argument is derived rather from the past than from the future. We maintain that the visible universe—that is to say the universe of atoms—must have had its origin in time, and that while THE UNIVERSE is, in its widest sense, alike eternal and infinite, the universe of atoms certainly cannot have existed from all eternity. While we freely confess that we cannot prove the finite magnitude of the universe of atoms, inasmuch as we cannot be sure that the stars which we see represent more than a small portion of this universe, we are unable to perceive any scientific principle which leads us to conclude that the number of such atoms must necessarily be infinite. But whether it be finite or infinite, we have very great difficulty in imagining this universe to be eternal. Regarding the atom as something that has been developed from a previously existing unseen universe, we cannot readily believe it capable of lasting for ever. But if there be any element of decay in the material substance of the visible universe, the assumption of its present infinity will not enable us to predicate its future eternity. Having thus defined our position, we may allow that in our earlier editions we have possibly given undue prominence to the particular argument in favour of an Unseen, which is derived from the future degradation of the energy of the present visible universe. We come now to the second part of our subject. All that we have yet endeavoured to show is that the theory of a future life is not in any way whatever in contradiction to any ascertained facts or principles of science. But we have not succeeded in finding any proof that arrangements have been made in the Unseen world for our translation thither after death. It has been shown that there is nothing in the whole range of science to lead us to suppose that life is impossible after death; but we have yet to inquire what evidence, if any, exists in favour of a future state. Now it is well known that the followers of Christianity believe they have received such evidence in virtue of the resurrection of Christ, and it is equally well known that of late years a school of scientific men have arisen who reject such an event as one impossible to be believed.
