"What is strength, -the brute hardness of iron, or the more delicate strength of steel? Which is the stronger, -the physical frame that can strike the harder blow, or that which can endure the greater strain and yet last longer?" "No wise person believes in any "reform against Nature," or that we can get beyond the laws of Nature. If I believed the limitations of sex to be inconsistent with woman suffrage for instance, I should oppose this; but I do not see why a woman cannot form political opinions by her baby's cradle, as well as her husband in his workshop, while her very love for the child commits her to an interest in good government. Our duty is to remove all the artificial restrictions we can." "As a matter of social philosophy, this train of thought logically leads to co-education, impartial suffrage, and free co-operation in all the affairs of life. As a matter of individual duty, it teaches the old moral to "act well your part." No wise person will ever trouble himself or herself much about the limitations of sex in intellectual labor."
