After reading well over a thousand economic writings of earlier date than 1734 I would put Cantillon's analysis of the circulation of wealth, trite as it may now appear, on the same level of priority as Harvey's study of the circulation of the blood. So eminent an authority on the history of economic thought as Professor Gide claims for J. B. Say that he "first employed the well-chosen term
Entrepreneur to designate that most important economic function of the man who collects in his hands the productive forces of capital—labour and natural agents".
And again, J. B. Say "gave economic science its present form and its definitions... (e.g. the term
'Entrepreneur' which has been borrowed by most other languages)".
Traité appeared in 1803. It is unnecessary to point out that Cantillon anticipated him completely 70 years earlier, or to enlarge here upon the fact that Cantillon's honourable place in the history of economic thought is now definitely and finally assured.
