It will be said _some_ energy is needed to pull a hair-trigger, to open the throttle-valve of an engine, to press the button which shall shatter a rock. Granted: but the work-concomitants of that energy are all familiar, and equally present whether it be arranged so as to produce any predetermined effect or not. The opening of the throttle-valve for instance demands just the same exertion, and results in just the same imperceptible transformation of fully-accounted-for energy, whether it be used to start a train in accordance with a time-table and the guard's whistle, or whether it be pushed over, as if by the wind, at random. The shouting of an order to a troop demands vocal energy and produces its due equivalent of sound; but the intelligibility of the order is something superadded, and its result may be to make not sound or heat alone, but History. Energy must be _available_ for the performance of any physical operation, but the energy is independent of the determination or arrangement. Guidance and control are not forms of energy, nor need they be themselves phantom modes of force: their superposition upon the scheme of Physics need perturb physical and mechanical _laws_ no whit, and yet it may profoundly affect the consequences resulting from those same laws. The whole effort of civilisation would be futile if we could not guide the powers of nature. The powers are there, else we should be helpless; but life and mind are outside those powers, and, by pre-arranging their field of action, can direct them along an organised course. * * * * * And this same life or mind, as we know it, is accessible to petition, to affection, to pity, to a multitude of non-physical influences; and hence, indirectly, the little plot of physical universe which is now our temporary home has become amenable to truly spiritual control. I lay stress upon a study of the nature and mode of human action of the interfering or guiding kind, because by that study we must be led if we are to form any intelligent conception of divine action. True, it might be feasible to admit divine agency and yet to deny the possibility of any human power of the same kind,—though that would be a nebulous and at least inconclusive procedure; but if once we are constrained to admit the existence and reality of human guidance and control, superposed upon the physical scheme, we cannot deny the possibility of such power and action to any higher being, nor even to any totality of Mind of which ours is a part.
