X = F. A. Hayek, Denationalization of Money (pp. 83-4):

His task ought to be, as I will not cease repeating, to make politically possible what today may be politically impossible. To decide what can be done at the moment is the task of the politician, not of the economist, who must continue to point out that to persist in this direction will lead to disaster.
