Famous quotes containing the words hard and/or problem:
“More than illness or death, the American journalist fears standing alone against the whim of his owners or the prejudices of his audience. Deprive William Safire of the insignia of the New York Times, and he would have a hard time selling his truths to a weekly broadsheet in suburban Duluth.”
—Lewis H. Lapham (b. 1935)
“It is part of the educator’s responsibility to see equally to two things: First, that the problem grows out of the conditions of the experience being had in the present, and that it is within the range of the capacity of students; and, secondly, that it is such that it arouses in the learner an active quest for information and for production of new ideas. The new facts and new ideas thus obtained become the ground for further experiences in which new problems are presented.”
—John Dewey (1859–1952)
