Of the Limit of Limits
The hope, as you'll know, is in the existence of a loving and a moving God. The doubt--that is to say: the skepticism, the intellectual rigour--is of the absolute authority (nay, the tyranny) of the material.
As with all attempts to make sense of an infinite universe, this is probably crude, simplistic, naive.
But the question remains: which is the more unreasonable? A humble acceptance of the essential (and indisputable) mystery of things? Or the hubristic presumption that because man is the measure of all things, it follows that he is also somehow in control of them?
