Famous quotes containing the words fill and/or factor:
“Let no one think that I do not love the old ministers. They were, probably, the best men in their generation, and they deserve that their biographies should fill the pages of the town histories. If I could but hear the “glad tidings” of which they tell, and which, perchance, they heard, I might write in a worthier strain than this.”
—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)
