possibility, they become utterly worthless; seeing that we can never have any means whereby to test the actual value of whatever transcendental probabilities they may appear to establish. Therefore it is that even the most ultimate of relative truths with which, as we have seen, the question of Theism is so vitally associated, is almost without meaning when contemplated in an absolute sense. What, then, is the effect of these metaphysical considerations on the position of Theism as we have seen it to be left by the highest generalisations of physical science? Let us contemplate this question with the care which it deserves. In the first place, it is evident that the effect of these purely formal considerations is to render all reasonings on the subject of Theism equally illegitimate, unless it is constantly borne in mind that such reasonings can only be of relative signification. Thus, as a matter of pure logic, these considerations are destructive of all assignable validity of any such reasoning whatsoever. Still, even a strictly relative probability is, in some undefinable degree, of more value than no probability at all, as we have seen these same formal considerations to show (see Sec. 40); and, moreover, even were this not so, the human mind will never rest until it attains to the furthest probability which to its powers is accessible. Therefore, if we do not forget the merely relative nature of the considerations which are about to be adduced, by adducing them we may at the same time satisfy our own minds and abstain from violating the conditions of sound logic.
