Famous quotes containing the words unknown and/or signal:
“So that this beautiful realm of hers was held in her mind extended, or lengthened: it had been finite, bounded, known utterly and in every detail, self-enclosed ... but now it lapped and rippled out and upwards beyond there into hinterlands that were like unknown possibilities in her own mind.”
—Doris Lessing (b. 1919)
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. 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)
