"In the first place, it is clear that by self-existence we especially mean, an existence independent of any other — not produced by any other: the assertion of self-existence is simply an indirect denial of creation.... Self-existence, therefore, necessarily means existence without a beginning; and to form a conception of self-existence is to form a conception of existence without a beginning. Now by no mental effort can we do this.... To this let us add, that even were self-existence conceivable, it would not in any sense be an explanation of the Universe.... Thus the Atheistic theory is not only absolutely unthinkable, but, even if it were thinkable, would not be a solution. The assertion that the Universe is self-existent does not really carry us a step beyond the cognition of its present existence; and so leaves us with a mere restatement of the mystery."
