The Progress of Fifty Years (1893)
Context: Half a century ago women were at an infinite disadvantage in regard to their occupations. The idea that their sphere was at home, and only at home, was like a band of steel on society. But the spinning-wheel and the loom, which had given employment to women, had been superseded by machinery, and something else had to take their places. The taking care of the house and children, and the family sewing, and teaching the little summer school at a dollar per week, could not supply the needs nor fill the aspirations of women. But every departure from these conceded things was met with the cry, "You want to get out of your sphere," or, "To take women out of their sphere;" and that was to fly in the face of Providence, to unsex yourself in short, to be monstrous women, women who, while they orated in public, wanted men to rock the cradle and wash the dishes. We pleaded that whatever was fit to be done at all might with propriety be done by anybody who did it well; that the tools belonged to those who could use them; that the possession of a power presupposed a right to its use.

Pity the tortoise, the katydid, the wild-bird, and the ox. Poor, undeveloped, untaught creatures! Into their dim and lowly lives strays of sunshine little enough, though the fell hand of man be never against them. They are our fellow-mortals. They came out of the same mysterious womb of the past, are passing through the same dream, and are destined to the same melancholy end, as we ourselves. Let us be kind and merciful to them.
