The Fatal Deceit x 2
There are two articles currently circulating on Hayek entitled "The Fatal Deceit": One by Alan Ebenstein at Liberty that questions the authenticity of Hayek's last book (The Fatal Conceit); the other by Lindsay Perigo that questions the authenticity, so-to-speak, of Hayek's work in the battle for a free society.
I add my thoughts to Perigo's thread, starting here (and continuing here, here), here, and here.
