See A. H. Strong, Christ in Creation, 163-166—“This conception of evolution is that of Lotze. That great philosopher, whose influence is more potent than any other in present thought, does not regard the universe as a _plenum_ to which nothing can be added in the way of force. He looks upon the universe rather as a plastic organism to which new impulses can be imparted from him of whose thought and will it is an expression. These impulses, once imparted, abide in the organism and are thereafter subject to its law. Though these impulses come from within, they come not from the finite mechanism but from the immanent God. Robert Browning’s phrase, ‘All’s love, but all’s law,’ must be interpreted as meaning that the very movements of the planets and all the operations of nature are revelations of a personal and present God, but it must not be interpreted as meaning that God runs in a rut, that he is confined to mechanism, that he is incapable of unique and startling manifestations of power. “The idea that gives to evolution its hold upon thinking minds is the idea of continuity. But absolute continuity is inconsistent with progress. If the future is not simply a reproduction of the past, there must be some new cause of change. In order to progress there must be either a new force, or a new combination of forces, and the new combination of forces can be explained only by some new force that causes the combination. This new force, moreover, must be intelligent force, if the evolution is to be toward the better instead of toward the worse. The continuity must be continuity not of forces but of plan. The forces may increase, nay, they must increase, unless the new is to be a mere repetition of the old. There must be additional energy imparted, the new combination brought about, and all this implies purpose and will. But through all there runs one continuous plan, and upon this plan the rationality of evolution depends. “A man builds a house. In laying the foundation he uses stone and mortar, but he makes the walls of wood and the roof of tin. In the superstructure he brings into play different laws from those which apply to the foundation. There is continuity, not of material, but of plan. Progress from cellar to garret requires breaks here and there, and the bringing in of new forces; in fact, without the bringing in of these new forces the evolution of the house would be impossible. Now substitute for the foundation and superstructure living things like the chrysalis and the butterfly; imagine the power to work from within and not from without; and you see that true continuity does not exclude but involves new beginnings.
