Readers of this excellent book should also read The Disciplined Mind, the latest book by Howard Gardner, because Gardner describes his book in the introduction as a "sustained dialectic -- read disagreement -- with E. D. Hirsch ...," describing 'core knowledge' as "an idle pursuit ... superficial and ... anti-intellectual" and later as "a course of study that blitzes, in thirty-five breathless weeks, from Plato to NATO or from Cleopatra to Clinton." Thus co-starring Hirsch as his most formidable adversary, the book is a sample both of how Gardner has habitually misrepresented Hirsch's program in order to attack him, but more notably shows the extent to which Gardner has come to agree with Hirsch. Amazon.com's features showing what other books in the same field customers buy reveals how all too often we read only the books on our side of an issue. In this case readers of Schools and any other of Hirsch's works should read his most illustrious adversary as well. It is revealing and perhaps encouraging.
