" In the name of truth and common sense, why should not one woman acknowledge that she can take more exercise than another? or, in other words, that she has a sound constitution; and why to damp innocent vivacity, is she darkly to be told, that men will draw conclusions which she little thinks of? Let the libertine draw what inference he pleases; but, I hope, that no sensible mother will restrain the natural frankness of youth, by instilling such indecent cautions. "

― Mary Wollstonecraft , A Vindication of the Rights of Woman
