Can there then be purpose without consciousness? There are adaptations in the vegetable world as well as in the animal, and of these we do not predicate conscious design. Nor can we, on the theory of life as the adaptation of a moving equilibrium to its environment, admit that these changes are due to mere happy accidents of origin and survival, for we are required to account for them as necessary results of their existence as moving equilibria. Yet if so the adjustments are so complex, so marvellous in their relations to the insect world and the animal world generally in view of their preservation and the propagation of their species, that purpose or means adapted to ends is the apparent characteristic. Means adapted to ends is denied in the "Happy Accident" theory, and is sought to be explained by the "Moving Equilibrium" theory. Yet when we come to consider the abstract conception of a moving equilibrium derived from our solar system we can discern no endeavour towards self-sustenance and self defence. No adaptations are there made to secure either of these objects. There is no purpose manifested, and no adjustment made in view of ends to be secured. On the other hand, there are many adaptations in the animal and vegetable worlds which are not consciously purposed. Since, however, ours is a critical task and not a reconstructive work we need do no more than point out that purposed actions in particular, and biological adaptations as a whole, are not explainable by regarding organisms as aggregates of the chemical elements acted upon by physical forces and constituting merely physical moving equilibria, of which the laws are similar to those derived from a consideration of moving equilibria like the solar system. Such a theory does not admit of purposed action. Stated in the abstract, the problem is how to explain the origin of purpose in a moving equilibrium--commencing from the solar system and proceeding to a self-feeding engine and pursuing our investigation to the abstract moving equilibrium of forces in which external inimical or favourable forces generate internal forces as a counterbalance, either of opposition or harmony of adjustment. Thus stated, the problem is purely of a dynamic nature, and would give an understanding of purpose as a dynamic relation of aggregates of forces. This is the true Spencerian view to take of the problem and its mode of settlement, but it is one to which Mr. Spencer does not apply himself. In the absence of such a study Mr. Spencer forsakes the true line of explanation required by his philosophy.
