Although Hayek and the Volker Fund had cooperated to bring about the composition of an American Road to Serfdom, Aaron Director—the individual anointed with this primary responsibility—never finished the book by the conclusion of the FMS around 1952. … The first half of the FMS essentially was devoted to debate over several possible trajectories of a reconceptualized liberal doctrine, whereas the last half basically served to consolidate a chosen trajectory. It is evident, however, that from 1946 to 1947 Director and Friedman were more than a little unclear as to how to accomplish this convergence; and that at that point in time Levi still clung to his classical liberal convictions.
