For, as the test of absolute inconceivability is equally annihilative in whichever direction it is applied, the test of relative inconceivability is the only one that remains; and as the formal conditions of a metaphysical teleology are undoubtedly present on the one hand, and the formal conditions of a physical explanation of cosmic harmony are no less undoubtedly present on the other hand, it follows that a theist and an atheist have an equal right to employ this test of relative inconceivability.
