"Passive acceptance of the teacher's wisdom is easy to most boys and girls. It involves no effort of independent thought, and seems rational because the teacher knows more than his pupils; it is moreover the way to win the favour of the teacher unless he is a very exceptional man. Yet the habit of passive acceptance is a disastrous one in later life. It causes man to seek and to accept a leader, and to accept as a leader whoever is established in that position." - Russell
"A professor is one who can speak on any subject -- for precisely fifty minutes." - Norbert Wiener
"The true teacher defends his pupils against his own personal influence." - Amos Bronson Alcott (1799 - 1888)
"Good teaching is one-fourth preparation and three-fourths pure theatre." -Gail Godwin
