The final cause of a thing, however, may mean, and with reference both to adjustment and design, neither its intrinsic nor extrinsic, but its ultimate end. It may mean, not merely that a thing is and was intended to be the mechanism or organism which science analyses and explains, and to stand in the relationships and fulfil the uses which science traces, but also that it will have, and was intended to have, a destination in the far future. We may ask, What is the goal towards which creation moves? What will be the fate of the earth? In what directions are vegetable and animal life developing? What is the chief end of man? Whither is history tending? What is the ideal of truth which science has before it, and which it hopes to realise? of beauty, which art has before it? of goodness, which virtue has before it? And although to most if not all of these questions probably no very definite and certain answer can be given, to deny that they can in any measure be answered, to pronounce all speculation regarding ultimate ends as wholly vain, would justly be deemed the expression of a rash and thoughtless dogmatism. Science claims not only to explain the past but to foretell the future. The power of prevision possessed by a science is the best criterion of its rank among the sciences when rank is determined by certitude. And most significant is the boldness with which some of the sciences have of late begun to forecast the future. Thus, with reference to the end of the world, the spirit of prophecy, which until very recently was almost confined to the most noted religious visionaries, is now poured largely out upon our most distinguished physicists. This we regard as a most significant and hopeful circumstance, and trust that ere long the prophets of science will be far less discordant and conflicting in their predictions even of the remotest issues than they must be admitted to be at present. While speculation as to final causes in the sense of ultimate ends is, within certain limits, as legitimate as it is natural, its results are undoubtedly far too meagre and uncertain to allow of our reasoning from them to the existence or wisdom of God. We must prove that there is a Divine Intelligence from what we actually perceive in things, and not from what we can conjecture as to the final destinies of things. In fact, until we have ascertained that there is a Divine Intelligence, and in some measure what are the principles on which that Intelligence proceeds, our chance of reaching truth through speculation as to the ultimate ends of things is, in all probability, exceedingly small. It is on no hazardous speculations of this kind that we would rest an argument for the Divine existence, although questions have been raised as to the Divine character and government which will, at a later stage of the discussion, involve us to some extent in the consideration of ultimate ends.
