Famous quotes containing the words exchange and/or factor:

    To coƶperate in the highest as well as the lowest sense, means to get our living together. I heard it proposed lately that two young men should travel together over the world, the one without money, earning his means as he went, before the mast and behind the plow, the other carrying a bill of exchange in his pocket. It was easy to see that they could not long be companions or coƶperate, since one would not operate at all. They would part at the first interesting crisis in their adventures.
    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)
