Yet, notwithstanding all these facts, notwithstanding all traditions and prejudices and social bias, the unexpected has happened, even in conservative, old-fashioned Germany. The German professor may be tenacious of preconceived views; he may be a stickler for ancient customs and usages; nevertheless, when he is called upon to give a question a categorical answer which can be arrived at by observation or experiment, he may generally, in spite of his likes or dislikes, be counted on to give a decision in accord with the principles of legitimate induction. He may have his prejudices--and who has not?--but, when one appeals to him in the name of science and justice, he will rarely be found wanting. Regardless of all personal consideration, he will feel that loyalty to science, of which he is the avowed devotee, requires him to consider a question proposed to him as he would a scientific problem--something to be decided solely by such evidence as may be available. To the exceeding gratification of the believers in the intellectual equality of the sexes, this proved to be the case in Herr Kirchhoff's investigation. The answers of the German professors, contrary to what most people would have anticipated, were, by a surprising majority, in favor of women. But their answers were in keeping with the changed educational conditions in Germany, as well as in other parts of the civilized world. Had Herr Kirchhoff undertaken his investigation a few decades earlier, the result would undoubtedly have been different, for women were then excluded from the universities and the professors had not had an opportunity of accurately testing their intellectual capacities. But having, during the latter part of the nineteenth century, had them as students in their lecture halls and laboratories, where they were able to study their mental powers and determine the value of their work by strict scientific methods, they were in a better position to express an opinion on the question at issue than would, a few years previously, have been possible. Accordingly, even the declared enemies of the woman's movement among the German professorate were forced to admit the intellectual equality of the two sexes. For they, too, as well as men of science in other parts of Europe, had been measuring skulls and weighing brains; they, too, had been studying woman's mental caliber in the light of the new psychology; they, too, had been watching her work in the various departments of the university; and, notwithstanding all their observations and experiments, they were unable to detect any difference between men and women in brain organization or in intellectual capacity. And, as might have been foreseen, results harmonized perfectly with those arrived at by investigators in other parts of the world--namely, that in things of the mind there is perfect sexual equality.
