单选题Why the inductive and mathematical sciences, after their first rapid development at the culmination of Greek civilization, advanced so slowly for two thousand years—and why in the following two hundred years a knowledge of natural and mathematical science has accumulated, which so vastly exceeds all that was previously known that these sciences may be justly regarded as the products of our own times—are questions which have interested the modern philosopher not less than the objects with which these sciences are more immediately familiar. The explanation which has become commonplace, that the ancients employed deduction chiefly in their scientific inquiries, while the modems employ induction, proves to be too narrow. For all knowledge is founded on observation, and proceeds from this by analysis, by induction and deduction, and if possible by verification, or by steps which are indeed parts of one method. A failure to employ adequately any one of these partial methods, an imperfection in the arts and resources of observation and experiment, carelessness in observation, neglect of relevant facts—these are the faults which cause all failures to ascertain truth; but this statement does not explain why the modem is possessed of a greater virtue, and by what means he attained his superiority. Much less does it explain the sudden growth of science in recent time. The attempt to discover the explanation of this phenomenon in the antithesis (对立面；对照；对仗) of "facts" and "theories"—in the neglect among the ancients of the former, and their too exclusive attention to the latter—proves also to be too narrow, as well as open to the charge of vagueness. Theories, if true, are facts—a particular class of facts indeed, generally complex, and if a logical connection subsists between their constituents, have all the positive attributes of theories. Nevertheless, this distinction, however inadequate it may be to explain the source of true method in science, is well founded, and suggests an important character in true method. A theory, on the other hand, if true has all the characteristics of a fact, except that its verification is possible only by indirect, remote, and difficult means. To convert theories into facts is to add simple verification, and the theory thus acquires the full characteristics of a fact.
