You could do worse than this as a starting point:
I haven't read the Fischer book yet (though I am very excited to), but I think Garry Kasparov is an absolutely brilliant writer, and his review of the new book is a loving but honest tribute to his deeply complicated boyhood hero.

This posts concludes bordering on intellectual arrogance (dismissing out of hand several recognized economists with appeal to the unnamed authority of the masses in claiming "no one" pays attention to their theories anymore, then using their irrelevance, falsely, as supporting the original point). Nevertheless, I think the underlying point is valid (many, in many unrelated domains, engage in cargo cult thinking by mistaking correlates of a certain desired state as that which should be pursued, whether or not those correlates cause the underlying objective). I really admire Eric Falkenstein's thinking and writing - cogent, well reasoned.
