In the olden time, the church, by violating the order of nature, proved the existence of her God. At that time miracles were performed with the most astonishing ease. They became so common that the church ordered her priests to desist. And now this same church--the people having found some little sense--admits, not only, that she cannot perform a miracle, but insists that the absence of miracle--the steady, unbroken march of cause and effect, proves the existence of a power superior to nature. The fact is, however, that the indissoluble chain of cause and effect proves exactly the contrary. Sir William Hamilton, one of the pillars of modern theology, in discussing this very subject, uses the following language: "The phenomena of matter taken by themselves, so far from warranting any inference to the existence of a god, would on the contrary ground even an argument to his negation. The phenomena of the material world are subjected to immutable laws; are produced and reproduced in the same invariable succession, and manifest only the blind force of a mechanical necessity." Nature is but an endless series of efficient causes. She cannot create, but she eternally transforms. There was no beginning, and there can be no end. The best minds, even in the religious world, admit that in material nature there is no evidence of what they are pleased to call a god. They find their evidence in the phenomena of intelligence, and very innocently assert that intelligence is above, and in fact, opposed to nature. They insist that man, at least, is a special creation; that he has somewhere in his brain a divine spark, a little portion of the "Great First Cause." They say that matter cannot produce thought; but that thought can produce matter. They tell us that man has intelligence, and therefore there must be an intelligence greater than his. Why not say, God has intelligence, therefore there must be an intelligence greater than his? So far as we know, there is no intelligence apart from matter. We cannot conceive of thought, except as produced within a brain. The science, by means of which they demonstrate the existence of an impossible intelligence, and an incomprehensible power is called, metaphysics or theology. The theologians admit that the phenomena of matter tend, at least, to disprove the existence of any power superior to nature, because in such phenomena we see nothing but an endless chain of efficient causes--nothing but the force of a mechanical necessity. They therefore appeal to what they denominate the phenomena of mind to establish this superior power.
