Why Study Humanities? What I Tell Engineering Freshmen  Wisdom
from science writer John Horgan.     Along similar lines, I like
to tell students that in some subjects and some courses, the
assumption is that a good class moves everyone in the room from
disagreement to agreement, as the professor carefully presents
the evidence necessary to disprove various incorrect approaches.
But my job is to send students away from a discussion with more
questions they had than when they arrived.
