Hence, two unthinkables are presented to our choice; one of which is an eternity of matter and of force,[32] and the other an Infinite Mind, so that in this respect again the two theories are tolerably parallel; and therefore, all that can be concluded with rigorous certainty upon the subject is, that neither theory has anything to gain us against the other from an appeal to the test of inconceivability. Yet we have seen that this is a test than which none can be more ultimate. What then shall we say is the final outcome of this discussion concerning the rational standing of the teleological argument? The answer, I think, to this question is, that in strict reasoning the teleological argument, in its every shape, is inadequate to form a basis of Theism; or, in other words, that the logical cogency of this argument is insufficient to justify a wholly impartial mind in accepting the theory of Theism on so insecure a foundation. Nevertheless, if the further question were directly put to me, 'After having heard the pleading both for and against the most refined expression of the argument from teleology, with what degree of strictly rational probability do you accredit it?'--I should reply as follows:--'The question which you put I take to be a question which it is wholly impossible to answer, and this for the simple reason that the degree of even rational probability may here legitimately vary with the character of the mind which contemplates it.' This statement, no doubt, sounds paradoxical; but I think it is justified by the following considerations. When we say that one proposition is more conceivable than another, we may mean either of two very different things, and this quite apart from the distinction previously drawn between symbolic conceptions and realisable conceptions. For we may mean that one of the two propositions presents terms which cannot possibly be rendered into thought at all in the relation which the proposition alleges to subsist between them; or we may mean that one of the two propositions presents terms in a relation which is more congruous with the habitual tenor of our thoughts than does the other proposition. Thus, as an example of the former usage, we may say, It is more conceivable that two and two should make four than that two and two should make five; and, as an example of the latter usage, we may say, It is more conceivable that a man should be able to walk than that he should be able to fly. Now, for the sake of distinction, I shall call the first of these usages the test of _absolute_ inconceivability, and the second the test of _relative_ inconceivability. Doubtless, when the word "inconceivability" is used in the sense of relative inconceivability, it is incorrectly used, unless it is qualified in some way; because, if used without qualification, there is danger of its being confused with inconceivability in its absolute sense. Nevertheless, if used with some
