Matching Quote

"I claim ... that there is a feminine as well as a masculine side to truth ...That as the man is more noble in reason, so the woman is more quick in sympathy. That as he is indefatigable in pursuit of abstract truth, so is she in caring for the interests by the way—striving tenderly and lovingly that not one of the least of these "little ones" should perish. That while we not unfrequently see women who reason, we say, with the coolness and precision of a man, and men as considerate of helplessness as a woman, still there is a general consensus of mankind that the one trait is essentially masculine and the other as peculiarly feminine. That both are needed to be worked into the training of children, in order that our boys may supplement their virility by tenderness and sensibility, and our girls may round out their gentleness by strength and self-reliance. That, as both are alike necessary in giving symmetry to the individual, so a nation or a race will degenerate into mere emotionalism on the one hand, or ballism on the other, if dominated by either exclusively; lastly, and most emphatically, that the feminine factor can have its proper effect only through woman's development and education so that she may fitly and intelligently stamp her force on the forces of her day, and add her modicum to the riches of the world's thought."
