Famous quotes containing the words fill and/or factor:
“It is the characteristic of great poems that they will yield of their sense in due proportion to the hasty and the deliberate reader. To the practical they will be common sense, and to the wise wisdom; as either the traveler may wet his lips, or an army may fill its water-casks at a full stream.”
—Henry David Thoreau (1817–1862)
“Children of the middle years do not do their learning unaffected by attendant feelings of interest, boredom, success, failure, chagrin, joy, humiliation, pleasure, distress and delight. They are whole children responding in a total way, and what they feel is a constant factor that can be constructive or destructive in any learning situation.”
—Dorothy H. Cohen (20th century)
