If the existing mental characteristics of women are thus valuable even in aid of speculation, they are still more important, when speculation has done its work, for carrying out the results of speculation into practice. For the reasons already given, women are comparatively unlikely to fall into the common error of men, that of sticking to their rules in a case whose specialities either take it out of the class to which the rules are applicable, or require a special adaptation of them. Let us now consider another of the admitted superiorities of clever women, greater quickness of apprehension. Is not this pre-eminently a quality which fits a person for practice? In action, everything continually depends upon deciding promptly. In speculation, nothing does. A mere thinker can wait, can take time to consider, can collect additional evidence; he is not obliged to complete his philosophy at once, lest the opportunity should go by. The power of drawing the best conclusion possible from insufficient data is not indeed useless in philosophy; the construction of a provisional hypothesis consistent with all known facts is often the needful basis for further inquiry. But this faculty is rather serviceable in philosophy, than the main qualification for it: and, for the auxiliary as well as for the main operation, the philosopher can allow himself any time he pleases. He is in no need of the capacity of doing rapidly what he does; what he rather needs is patience, to work on slowly until imperfect lights have become perfect, and a conjecture has ripened into a theorem. For those, on the contrary, whose business is with the fugitive and perishable--with individual facts, not kinds of facts--rapidity of thought is a qualification next only in importance to the power of thought itself. He who has not his faculties under immediate command, in the contingencies of action, might as well not have them at all. He may be fit to criticize, but he is not fit to act. Now it is in this that women, and the men who are most like women, confessedly excel. The other sort of man, however pre-eminent may be his faculties, arrives slowly at complete command of them: rapidity of judgment and promptitude of judicious action, even in the things he knows best, are the gradual and late result of strenuous effort grown into habit.
