... the teacher is a sculptor of the intangible future.  There is no more 
dangerous occupation on the planet, for what we conceive as our masterpiece 
may appear out of time to mock us -- a horrible caricature of ourselves. 

The teacher must ever walk warily between the necessity of inducing those 
conformities which in every generation reaffirm our rebellious humanity, and 
of allowing for the free play of the creative spirit. 
 Loren Eiseley "The Night Country"
