Men . . . submit every where to oppression, when they have only to lift up their heads to throw off the yoke; yet, instead of asserting their birthright, they quietly lick the dust and say, let us eat and drink, for to-morrow we die. Women, I argue from analogy, are degraded by the same propensity to enjoy the present moment; and, at last, despise the freedom which they have not sufficient virtue to struggle to attain.
Mary Wollstonecraft, A Vindicaton of the Rights of Woman (1792), chapter 4.
