3. Finally, for operative activity, there must be an efficient cause putting in movement the productive law, over and above its intelligent apprehension just presupposed. This efficient Cause, as seen always in human Production, is a Will.

Now each several step in this series comes before us as an act of Mind. But out of this number one only needs to be examined here;—because

Purpose (1) has been treated of in Chapter II.

Will (3) occupies the close of this Essay.

No. 2, therefore, (divisible into a and b,) makes the proper subject-matter of the present Chapter. It has been written to meet the difficulties felt by a certain number of reasoners respecting the argument from Design. They are very often indisposed to accept that argument, because its analogical nature makes it appear circuitous; and because they hesitate when attempting to appreciate its exact value: compare p. 53 ante. There is also a lurking dread of that spectral shadow called Anthropomorphism, haunting some minds with a pertinacity, which may be estimated from p. 54 seq. By such reasoners let the present Chapter,—which proceeds not by way of analogy, but through a direct analysis of acknowledged facts—be read as a substitute for Chapter II. Or, they may if they please, consider the present and two following Chapters as a Treatise entirely distinct from the rest of the volume; this present Chapter serving as a brief statement of the case for physico-theology; while the two arguments ensuing sketch out Ethico- or Moral Theology; on which complementary modes of thought see p. 107 ante, together with text and notes now about to follow. Finally, by all those who accept the reasoning from Design as already explained, let both it and our other various lines of argument be treated as separate evidences of Natural Theology, each resting on its own grounds, but all consilient at last.

Analysis.—Advance and Retrogression of Discovery and of Civilization. Progress dependent on realizing the relativity between Power and Function. This condition of success is examined at length.

Perception of existing Relations, and creation of new ones by human Reason and Will. Illustrations from histories of Invention, Art, Education, and Self-Education.

Production of Change within ourselves. Self conquest, Self formation, and Re-formation. Inability of animals arises from domination of motives unalterable by themselves and instinctively apprehended. Training relative to motor instincts of various sorts. Self-training requires freedom from the domination of any single unbalanced or unalterable impulse. It implies the power of using motives as counterpoises, and of introducing new elements into the sphere of our ideals.

Influence of human presence upon the education of animals; influence of the Divine Idea upon Man.

Transition from the sphere of Intellect to that of Will in relation to the World. The Spring of Production a movement of Will; the Idea of Production an insight into the Mind of Nature; discovered not logically, but as shewn in operation in Nature. Law and Idea, Intelligence and Matter. Manifold Forces imply a central Unity. Putting aside the analogical inference from apparent Purpose, the question of operative Law (Force, Form, Mind,) is examined in its many activities, their correlations and their underlying Oneness.
