The comments here are disappointingly one-sided. Nowhere did Brooks suggest that he wanted to return to the good ol' days with all its warts. Incremental evolution of systems is a known good strategy. There's no reason whatever to believe that that doesn't apply to institutions, too. If you find yourself unable to see how tradition can transmit useful information through a society made up of people of varying critical thinking abilities, you may be letting your politics unreasonably bias your analysis.
Considering what value traditions and institutions may serve can be an intellectual exercise. It doesn't mean you suddenly want to rescind female voting and return to slavery. It seems impossible to have interesting discussions with about 99.5% of the population, because they show not even the remotest ability to avoid emotional reactions to words.
