Competent to judge...

Classical inquiry possesses three essential attributes. The first of these is general curiosity...Second, one responds to these questions by forming imaginative hypotheses...Third, one completes the inquiry by devising methods for testing the hypothesis...This bent of mind allows the educated man to go on educating himself or extending the realms of knowledge for his fellows...This is the person competent to judge what the experts say without being an expert himself.
~David Hicks, Norms and Nobility: A Treatise on Education, p.18
