Sir:
If economics has no definition, we may still practice it, in an
unselfconscious way. If one wants to reflect on Economics, and the
History of Economics does, then some idea of the subject of reflection
is necessary, however fuzzy it may be. Selfconsciousness is of the
essence of the History of Economics. How can one ramble through
Sociology, Political Science, etc., without some way of distinguishing
those disciplines from Economics?
