relative--it is in the form of an unreal dream; but reality somehow gives form to the dream, for there are always the compensating conceptions. The contradictions by which the compensation has been effected are, then, interpretable not more as causes of doubting science than as reasons for confidence in it. Thus, to be tedious again, the special science is relative and formal; it is a peculiar system of ingenious abstractions that in so far are also errors; but its formal character includes also contradiction; its errors are so related as to correct and balance each other; so that, even in the face of our necessary scepticism about it, science has been evident to us, as also was the consciousness of ordinary life, as somehow always building better than it knows or than its methods or ideals and doctrines viewed only from without would lead one to expect. Moving in it we have certainly felt the presence of, something, not yet called by name, which is very like a principle or power of validity, preserving the reality of things even in and through the relativity and contradiction under which the things are seen. While the letter of our knowledge, even of our scientific knowledge, must ever have an indeterminate future; while rest or stability, ultimate reality or consistency is quite impossible to it, still its inner, active spirit seems a source of faith that is inviolable, that cannot be shaken. Different [p.106] quantities, such as four and two, and sixteen and eight, do not make the same sum, much less are they the same digits; but they are in the same ratio, and similarly the truth of science would seem to lie in the ratio, the working together, of the errors of science. Outwardly and materially changing with time and with people, assuming ever new forms and comprising always new doctrines, science nevertheless, as an active force, as a positive resultant, is at least now conceivably always the same and applicable to the same life. Even the Babylonians of an ancient day successfully predicted eclipses, the very errors of their astronomy working together for truth, exactly as the heresies of pagan religion seem to have balanced each other to the preservation and the development of the life which we of the present day and the Christian civilization are pleased to call our own. Accordingly the science we have to doubt is also manifest to us as at least a possible object of faith. The very causes of our doubt before our very eyes have turned, or are in process of turning, into possible bases of belief, and our confession of doubt as it proceeds is proving ever more worth making. We are trying to be such honest doubters. We are indeed such penitent believers. III. SCIENCE WOULD BE AGNOSTIC.
