The world of humanity is possessed of two wings: the male and the female. So long as these two wings are not equivalent in strength, the bird will not fly. Until womankind reaches the same degree as man, until she enjoys the same arena of activity, extraordinary attainment for humanity will not be realized; humanity cannot wing its way to heights of real attainment. When the two wings or parts become equivalent in strength, enjoying the same prerogatives, the flight of man will be exceedingly lofty and extraordinary. Therefore, woman must receive the same education as man and all inequality be adjusted. Thus, imbued with the same virtues as man, rising through all the degrees of human attainment, women will become the peers of men, and until this equality is established, true progress and attainment for the human race will not be facilitated.
