The acid of the more rational ideas which the youth acquires by social intercourse or private study may in cases relieve the mind of the erroneous ideas implanted in childhood. But what is likely to be the practical outcome of this transformation of the mind in the sphere of conduct? We must not forget that in most cases the emotions associated with the early ideas remain in the deeper folds of the heart. Hence it is that we find in so many men such a flagrant and lamentable antithesis between the thought and the deed, the intelligence and the will; and this often leads to an eclipse of good conduct and a paralysis of progress. This primary sediment which we owe to our mothers is so tenacious and enduring—it passes so intimately into the very marrow of our being—that even energetic characters, which have effected a sincere reform of mind and will, have the mortification of discovering this Jesuitical element, derived from their mothers, when they turn to make an inventory of their ideas. Woman must not be restricted to the home. The sphere of her activity must go out far beyond her home: it must extend to the very confines of society. But in order to ensure a helpful result from her activity we must not restrict the amount of knowledge we communicate to her; she must learn, both in regard to quantity and quality, the same things as man. When science enters the mind of woman it will direct her rich vein of emotion, the characteristic element of her nature, the glad harbinger of peace and happiness among men. It has been said that woman represents continuity, and man represents change: man is the individual, woman is the species. Change, however, would be useless, fugitive, and inconstant, with no solid foundation of reality, if the work of woman did not strengthen and consolidate the achievements of man. The individual, as such, is the flower of a day, a thing of ephemeral significance in life. Woman, who represents the species, has the function of retaining within the species the elements which improve its life, and to discharge this function adequately she needs scientific instruction. Humanity will advance more rapidly and confidently in the path of progress and increase its resources a hundredfold if it combines the ideas acquired by science with the emotional strength of woman. Ribot observes that an idea is merely an idea, an act of intelligence, incapable of producing or doing anything, unless it is accompanied by an emotional state, a motive element. Hence it is conceived as a scientific truth that, to the advantage of progress, an idea does not long remain in a purely contemplative condition when it appears. This is obviated by associating the idea with emotion and love, which do not fail to convert it into vital action.
