Famous quotes containing the words main and/or parameters:
“Of all wit’s uses, the main one
Is to live well with who has none.”
—Ralph Waldo Emerson (1803–1882)
“Men have defined the parameters of every subject. All feminist arguments, however radical in intent or consequence, are with or against assertions or premises implicit in the male system, which is made credible or authentic by the power of men to name.”
—Andrea Dworkin (b. 1946)
