In regard to Western scholastic philosophy of the Middle Ages, every one repeats the laconic judgment, that it is “philosophy in the service, under the sway and direction, of Catholic theology.” It could be nothing else; and it seems that one has said everything after announcing this clear-cut formula. This current definition, susceptible of the most different meanings, is found on the first page of a recent book, published during the War, on the philosophy of the Middle Ages; and though the author gives a very mild interpretation of it, it is offered to the reader as an abridged thesis, in which one finds condensed all that is important to know on the subject. “Scholasticism is Philosophy placed at the service of already established ecclesiastical doctrine, or at least philosophy placed in such a dependence on this doctrine that it becomes an absolute Rule when both meet on common ground.”
Now this current definition of scholastic philosophy in the Middle Ages defines it very badly, because it is a mixture of the true and the false, of accuracy and of inaccuracy. It must be distrusted, like those equivocal maxims which John Stuart Mill calls “sophisms of simple inspection,” which by force of repetition enjoy a kind of transeat or vogue in science without being questioned.
