Famous quotes containing the words substantial and/or factor:
“Some people are so extremely whiffling and inconsiderable that they are as far from any real faults as from substantial virtues.”
—François, Duc De La Rochefoucauld (1613–1680)
“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)
