I am going to make one more comment on this matter, having now apologized for misleading folks and misattributing remarks to Bruce Caldwell that he did not make. There are two broader history of thought issues at stake. One is where did someone get an idea. The other is where did they get their label for the idea. Regarding the first, although I do not have a specific page cite in front of me, I certainly remember reading in Hayek him arguing that Adam Smith had the idea of "spontaneous order," although clearly he did not use that label. I do not know if Hayek made the label himself up independently, whether it came to him from his reading of Mill, who clearly did use the label, or from reading someone else. The only way to know for sure regarding this latter would be if Hayek himself (or someone else in a position to know authoritatively) wrote down specifically that he indeed did take the label from a particular source other than his own ruminations. And has been argued by several folks, it may not really matter all that much anyway. Barkley Rosser
