Context

“A theory is a form of apperception, and in applying it to the facts, although our first concern is naturally the adequacy of our instrument of comprehension, we are also influenced, more than we think, by the ease and pleasure with which we think in its terms, that is, by its beauty. The case of two alternative theories of nature, both exhaustive and adequate, may seem somewhat imaginary. The human mind is, indeed, not rich and indeterminate enough to drive, as the saying is, many horses abreast; it wishes to have one general scheme of conception only, under which it strives to bring everything. Yet the philosophers, who are the scouts of common sense, have come in sight of this possibility of a variety of methods of dealing with the same facts.” source
