might really frame a curious inquiry as respects this flowing tide of process and production, production and process, with its commingling currents and waves which seem to interrupt each other like circles of diffracted light. We might ask which of all these parts of the moving diorama is most distinctly human. I believe most people would say, those scenes in which mind, not mere workmanship, is most evidently discernible. Professor Powell seems to have thought so too. The difficulty we have been discussing he states as an objection requiring solution.[20] "In those cases most nearly approaching the nature of human works, such as the varied and endless changes in matter going on in the _laboratory of nature_, the results, even when most analogous to those obtained in human laboratories, yet present no marks of the process or of the means employed, by which to recognise the analogous workman; and in all the grander productions, the incessant evolutions of vegetable and animal life, which no human laboratory can produce,--in the structure of earth and ocean, or the infinite expanse of the heavens and their transcendent mechanism, still further must we be from finding any analogy to the works of man, or, by consequence, any analogy to a personal individual artificer." The next paragraph contains his own judgment. "But the more just view of the case is that which arises from the consideration that the real evidence is that of _mind_ and _intelligence_; for here we have a proper and strict analogy. _Mind_ directing the operations of the laboratory or the workshop, is no part of the _visible apparatus_, nor are its operations seen in _themselves_--they are visible only in their _effects_;--and from effects, however dissimilar in magnitude or in kind, yet agreeing in the one grand condition of _order_, _adjustment_, profound and recondite connexion and dependence, there is the same evidence and outward manifestation of INVISIBLE INTELLIGENCE, as vast and illimitable as the universe throughout which those manifestations are seen." This second extract may be analysed into distinct propositions somewhat as follows:-- In a manufactory,-- Mind is no part of the visible apparatus--nor are its operations visible,-- But the effects make the operations manifest.-- In the universe,-- Effects may be seen differing from Human productions in many ways,--but agreeing in one common characteristic,--order--adjustment--hidden interdependence. Such effects make manifest the operation of an Invisible Intelligence as vast as the Universe itself.
