This all raises serious questions about Fragile Nassim’s foreword to Ammous’s book. Given he wrote the foreword — or if he had even so much as claimed to have read the book — how could he possibly not know who George Selgin is? How? This utterly pointless Twitter embarrassment revealed much more than Fragile Nassim intended. In the proper context his behaviour here is utterly damning. You can’t put the toothpaste back in the tube.
