Richard Cantillon's Essay on the Nature of Trade in General

 The Essay on the Nature of Trade in General was written in the early 1730s by Richard Cantillon, a speculator and banker who had made a vast fortune during the Mississippi and South Sea Bubbles of 1719-20. The work remained unpublished for about two decades, but when it appeared posthumously in Paris in 1755 the book was immediately recognised as a brilliant genre-defining contribution to the then emerging intellectual discipline of political economy.
