Douglass was involved in a continuing debate with an anonymous
advocate of paper money, who we now believe to have been Hugh Vans
(a.k.a. Vance). Shortly after Douglass's Discourse appeared,
Vans wrote a pamphlet attempting to refute it. Douglass then wrote the
Postscript to answer Vans's pamphlet. The Postscript
was originally published in June of 1740, and has since been reprinted
in Andrew MacFarland Davis's Colonial Currency Reprints, Volume
IV, pp. 45-64. Since the Postscript is a continuation of the
Discourse, a reader should begin with the Discourse.
