¹ Caldwell makes what strikes me as the mystifying claim that Hayek’s use of the term “spontaneous order” in this context is not the same concept that Hayek will later develop. While the analogy Hayek draws upon is from the field of chemistry, to my mind, this surely is one instance of orders formed by elements following rules and not by top-down design, the hallmark of a spontaneous order. But perhaps I am missing something.

² The 1960s saw the development of related topics such as search theory and the economics of information. One can’t help but wonder if any of those who developed that literature attended Hayek’s lectures.
