physical cause, then of course we may dispute about the various external influences which, when it changes its position, sway it to and fro, like a scarecrow in a garden; but to assert that the motive cause _is_ physical, this is an assumption in a case, when our question is about a matter of fact, not about the logical consequences of an assumed premiss. And, in like manner, if a people prays, and the wind changes, the rain ceases, the sun shines, and the harvest is safely housed, when no one expected it, our Professor may, if he will, consult the barometer, discourse about the atmosphere, and throw what has happened into an equation, ingenious, even though it be not true; but, should he proceed to rest the phenomenon, in matter of fact, simply upon a physical cause, to the exclusion of a divine, and to say that the given case actually belongs to his science because other like cases do, I must tell him, _Ne sutor ultra crepidam_: he is making his particular craft usurp and occupy the universe. This then is the drift of my illustration. If the creature is ever setting in motion an endless series of physical causes and effects, much more is the Creator; and as our excluding volition from our range of ideas is a denial of the soul, so our ignoring Divine Agency is a virtual denial of God. Moreover, supposing man can will and act of himself in spite of physics, to shut up this great truth, though one, is to put our whole encyclopædia of knowledge out of joint; and supposing God can will and act of Himself in this world which He has made, and we deny or slur it over, then we are throwing the circle of universal science into a like, or a far worse confusion.
