Famous quotes containing the words absolute and/or signal:
“As liberty of thought is absolute, so is liberty of speech, which is “inseparable” from the liberty of thought. Liberty of speech, moreover, is essential not only for its own sake but for the sake of truth, which requires absolute liberty for the utterance of unpopular and even demonstrably false opinions.”
—Gertrude Himmelfarb (b. 1922)
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control.

When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.”
—Selma H. Fraiberg (20th century)
