“a woman should have every honorable motive to exertion which is enjoyed by man, to the full extent of her capacities and endowments. The case is too plain for argument. Nature has given woman the same powers, and subjected her to the same earth, breathes the same air, subsists on the same food, physical, moral, mental and spiritual. She has, therefore, an equal right with man, in all efforts to obtain and maintain a perfect existence.”
