Newman writes, “I would rather have to maintain that we ought to begin with believing everything that is offered to our acceptance, than that it is our duty to doubt everything. The former, indeed, seems the true way of learning.”
I think David Hick's statement in Norms and Nobility reflects Newman's sentiment above, and also touches on Karen's statements about truth:
"Take skepticism, for example. As commonly applied in modern classrooms, it kills the flowering of imagination which must accept and feed upon a premise, no matter how fantastic, before rejecting it. Premature skepticism tends to separate thinking from acting, forcing the precept to withstand an adolescent's stubborn incredulity before his is prepared to put it to the test of acting upon it. Indeed, youthful skepticism often amounts to little more than an arrogant prejudice against novel or difficult ideas. It can lead to cynicism--a sophistical (now sophisticated) belief that all ideas are relative and that none is worthy of one's wholehearted allegiance."
(Karen Glass, who I noticed has commented above 🙂, has an excellent chapter in her book Consider This about the important role humility plays in learning, which I highly recommend!)
