We may make two separate affirmations: as, for example, that ‘the thermometer is 6° F. below zero,’ and that ‘water has become solid;’ or, again, we may state, ‘my fingers rest upon the key-board of an organ,’ and ‘now they move, and a symphony of Beethoven’s is floating in the air.’ These are ‘sequences;’ but is that enough? No. Instantly the mental act that _interprets_ them is supplied. In both cases, our consciousness and reason are compelled to demand the exercise of power, by means of which one event succeeds the other. We are absolutely and irresistibly certain, in the latter case, that it must be so. A direct act of volition changed the fingers from rest into rhythmic motion, causing the organ to pour out music; and, by an intellectual necessity, we see that a diminished temperature, and frozen water, are not sequences merely; they must be related: and this conviction is not changed, though, by means of research, we find their sequential relation to be the result of the continuity of prior effects; we still retain the unaltered judgment, that, if we go back far enough, we must be in the presence of a cause. The mind cannot dispense with the link of power uniting sequences. Then, if by long trains of sequential effects and secondary causes we are led up, not by demonstration, but by irresistible moral conviction, to a Primordial Power, a source of all, what is such creative cause? Is it inevitably God? Is the universe, as we know it, infinite? Who dare say? Though we know that the vast looming firmament, in which the ‘milky way’ stretches its depths and winds its awful amplitudes, is beyond all finite power to follow; yet, it may be but a complex particle in a universe of universes, stretching on, and for ever on, over the bourneless immensity of the unknown. If that be so, we can make no useful inference from our finite universe. We could infer only a finite creator from a finite cosmos. To be finite is to be infinitely less than infinite; and such a being could not be the ineffable majesty of mind and might, which we apprehend, but cannot comprehend, as the Creator. If such a limited power could be conceived, because it is finite, it of necessity began to be; and therefore its very existence was of necessity caused. We seek _its_ cause, as we do that of all other secondary causes; until at last we reach the only position in which there is mental rest, an infinite cause of all causes, the primordial and ultimate reality of all being.
