In certain nations, women, whether married or not, have been placed in a state of perpetual wardship: this has been evidently founded on the notion of a decided inferiority in point of intellects on the part of the female sex, analogous to that which is the result of infancy or insanity on the part of the male. This is not the only instance in which tyranny has taken advantage of its own wrong, alleging as a reason for the domination it exercises, an imbecility, which, as far as it has been real, has been produced by the abuse of that very power which it is brought to justify. Aristotle, fascinated by the prejudice of the times, divides mankind into two distinct species, that of freemen, and that of slaves. Certain men were born to be slaves, and ought to be slaves.Why? Because they are so.
