There were, of course, many reasons for the hostility borne to female slaves by their free sisters, not just the envy of their needs, health, and vitality. They envied them, interestingly, for their greater freedom, in its way, their emotional liberties, their honesty, their masters, their domination, their profound fulfillments, their radiance, their happiness. Too, it did not help that men, however inexplicably, seemed to care more for, and seek more avidly, and prize more highly, these lowly slaves, purchasable in markets, than themselves, in all their inestimable regalias of freedom and power.
