It is because women are never lazy. They don't know what it is to be quiet. They are Semiramides, and Cleopatras, and Joan of Arcs, Queen Elizabeths, and Catharine the Seconds, and they riot in battle, and murder, and clamour, and desperation.
If they can't agitate the universe and play at ball with hemispheres, they'll make mountains of warfare and vexation out of domestic molehills; and social storms in household teacups. Forbid them to hold forth upon the freedom of nations and the wrongs of mankind, and they'll quarrel with Mrs. Jones about the shape of a mantle or the character of a small maid-servant.
To call them the weaker sex is to utter a hideous mockery. They are the stronger sex, the noisier, the more persevering, the most self-assertive sex. They want freedom of opinion, variety of occupation, do they? Let them have it. Let them be lawyers, doctors, preachers, teachers, soldiers, legislators — anything they like — but let them be quiet — if they can.
