On Hayek's road to serfdom: 60 years later

Stimulated by recent work of Levy-Peart-Ferrant, Rosser and McPhail, I read The Road to Serfdom by projecting it onto four registers-security and freedom, impersonal forces and the market, rules and the rule of law, and language and education-and identify in each the need for judgement, hopefully balanced but inevitably arbitrary beyond an analytical threshold, a need exacerbated by incomplete and dispersed knowledge. My larger project is to understand the role of the expert, theoretician if one prefers, in a 'free' society.
