Merely having an open mind is nothing;
the object of opening the mind,
as of opening the mouth, is to shut it
again on something solid.
–G. K. Chesterton
I once had a debate about education with a professor of psychology. He said that it was his function to get rid of prejudices in his students. … Did this professor know what those prejudices meant for the students and what effect being deprived of them would have? Did he believe that there are truths that could guide their lives as did their prejudices? Had he considered how to give students the love of the truth necessary to seek unprejudiced beliefs, or would he render them passive, disconsolate, indifferent, and subject to authorities like himself?
