There is one thing a professor can be absolutely certain of: almost every student entering the university believes, or says he believes, that truth is relative.
We are like ignorant shepherds living on a site where great civilizations once flourished. The shepherds play with the fragments that pop up to the surface, having no notion of the beautiful structures of which they were once a part.
Students now arrive at the university ignorant and cynical about our political heritage, lacking the wherewithal to be either inspired by it or seriously critical of it.
