ABSTRACT
I observe two generalized media of exchange: “Money” and “Time”, the first one connected with the liberal tradition and “quantification”, the second one with the tradition of fundamental critique of capitalism and a “quantification taboo”. Two representatives of the two opposing intellectual threads are Karl Popper and Erich Fromm. Using the assumption of non-convex improvement sets A(x) I can integrate the two threads into a common model of adaptive preferences. However, the present book clearly is part of the liberal tradition of Popper and Hayek.
