Thus, when the primæval Nebula arose in Space (how or why it arose is not told us), its vapoury Law contained all that is, and all that can be:--Plato and Shakespeare, Moses and St. John glimmered in its tremulous twilight. Worlds inanimate and animate scintillated from its fires. What we call Heaven and Earth are its dumb children, its law-determined Evolutions. Thou and I, O reader, have harboured strange fancies;--let them go;--we are but parts of the Whole; and the Whole is a mechanical Unity. Now that we find ourselves disabused and illuminated, our great difficulty may perhaps be to fall down, Strauss-like, and worship this _Universum_. Can such worship, or such an object of worship, bless and satisfy our high aspiring race? Eyes that have watched for Righteousness, hearts that have yearned after it, let the answer come from you! In this answer lives or dies the twofold belief of the Natural Theologian, the twofold hope resulting to Mankind. The belief, that is to say, in a personal Immortality, the belief in a personal God. It may now seem plain that the readiest test of moral or religious Materialism is its doctrine, not of Body but of Soul. There is no charm in such a word as Matter to differentiate the character of a philosophy. Looking at the material world, any thinker may be a Natural Realist or a Pure Idealist; yet being either or neither, he may materialize, or the reverse, so far as Morals and Religion are concerned. The simple question ought rather to be; Is man mechanically governed by the Law which rules the world of Abiology (the lifeless inorganic world), or is he, can he become, a Law unto himself?[150] It would be unfair to omit impressing upon the reader's mind that physical science _per se_ is by no means answerable for ethico-religious Materialism. As a question of fact, it does not seem established that students of Nature, whether physicists or biologists, have, as such, been the chief offenders. On the contrary, for every single instance of the kind, it seems quite probable that at least _two_ metaphysical writers might be found guilty. Obviously, some such large proportion may reasonably be expected, when we consider that Determinism, (the word Mill and others prefer to Necessity), is a theory involving a certain kind of metaphysics. But the really largest crop of materializers arises from a Debateable Land. There is a hybrid class of "thinkers," concerning whom the best physical-science authorities allege that "such nebulous rascals are mere metaphysicians," while metaphysical speculators, pure and simple, feel quite sure that "though under a cloud, the gentlemen must be Physicists."[151]
