Famous quotes containing the words forced and/or induction:

—Anonymous Mother. From the Boston Women’s Health Book Collection. Quoted in The Joys of Having a Child, by Bill and Gloria Adler (1993)
“They relieve and recommend each other, and the sanity of society is a balance of a thousand insanities. She punishes abstractionists, and will only forgive an induction which is rare and casual.”
—Ralph Waldo Emerson (1803–1882)
