We publish in another column the announcement that Columbia will hereafter admit women to the School of Arts upon the same footing with men. This is a step toward progress, if we may judge from the high success which has been attained in similar actions by other universities. We need not refer to the work at present done by women at the Boston University and the university of Michigan. Sufficient proof that women can compete successfully with men upon a collegiate basis is found in a comparison of the work done by men and by women at those universities. Few will to day dare deny to women an equal right with men to achieve a collegiate education. Those who oppose the plan of co-education and decry its efficacy as a plan of education, are forced to advance arguments drawn from the domestic relations of woman to the home and the fact that the creation of Adam was prior to that of Eve. But when all has been said that can be said upon either side of the question, the fact yet remains that the world to-day is beginning to allow to women equal rights with men in every field which women care to enter. The recent action of the management of Columbia College will undoubtedly provoke a renewal of the old discussion of "Sex in Education," but successful precedent is now upon the side of the co-educators, and the final result cannot be mistaken. This action of Columbia will, without doubt, exercise a profound influence upon those who oppose her policy. But any educator who to-day defiantly closes his eyes and ears to a truth which all he may say or do will yet be heard and recognized, does not merit the name 'educator." If an opportunity to gain an education means an opportunity offered to men only, if the word college shall be allowed to stand as significant to the male gender only, if girls because they are girls, are to be forbidden privileges which are rights of their brothers then the action of Columbia was ill-advised. But if to learn applies with equal significance to all, if colleges are to be considered as common benefits open to either sex, if a bright, intelligent girl is to be allowed the privileges which are forced upon her, too often, stupid brother, then the action of Columbia College is significant as a step toward progress. We wish the reform every success, for it is a reform worthy of the highest success.
