individuality to compress itself so that it is long before the space conditions in the brain permit it to extend again—in case it is not simply choked by all the chaotic mass that has been absorbed. How many young girls have come to the university or to the art academy full of thirst for knowledge and energy for work! But after a few years they feel the disgust of surfeit, unless they have found a teacher who has been to them a leader to the essentials in science or in art. Then their joy in study could really be as rich as they had once dreamed it—yes, as perhaps even their grandmothers had dreamed it when they had to content themselves with their little text-books written for “girls.” Many young girls maintain to-day, through some teacher or some masculine comrade, that spiritual development which only an exceptional relationship between a father and daughter, a brother and sister, could give in earlier times. * * * * * When men and women can study together, then the relationship later between masculine and feminine fellow-workmen will, as a rule, be better than when the sexes work independently in the student days. It is true masculine competitors still have recourse to the weapon of spreading reports of the incapacity of their feminine competitors—at times honestly convinced of it themselves. The same weapon is of course turned also against masculine competitors. Yet there it is a question of the _individual_, while in regard to women, the _sex_ is often the only proof the man thinks he need assign for the inferiority of their work. It can be said, however, upon the whole, that the relationship between men and women professional colleagues exhibits the same good side as the common student life, although naturally to a lesser degree. The joint work does not often leave much time for significant interchange of ideas, and after working hours each usually longs for new faces. The influence of joint labour is often limited to the refining effect that the presence of one sex exercises upon the other. Small services are mutually rendered and each worker learns also to respect the achievements of the other; or one is provoked because the work which should have been dispatched by the other now falls to his share!
