The aristocratic and the modern were inextricably combined in Joseph Schumpeter. The paradoxes of this great economist, who also served as minister of finance in the post-World War I government of Austria, are suggested by the fact that at his first teaching post, he challenged the university librarian to a duel to win freer access to books for the students. Perhaps Schumpeter was attracted to the big issues because he himself witnessed drastic changes in society.

The point is that coordination can be achieved by either of two means: (1) with no one dictating anyone else's precise behavior, but everyone observing a set of rules, or (2) with someone (or perhaps more than one) directing the behavior of others. We refer to the first of the two means as coordination by rules and the second as coordination by command.
