Our inventions are wont to be pretty toys, which distract ourattention from serious things. Theyare but improved means to an unimproved end.Henry David Thoreau
Fashionable women regard themselves, and are regarded by men, as pretty toys or as mere instruments of pleasure; and the vacuity of mind, the heartlessness, the frivolity which is the necessary result of this false and debasing estimate of women, can only be fully understood by those who have mingled in the folly and wickedness of fashionable life.sarah grimké
