Note, the work's publication history is detailed in the <a href="http://www.oxforddnb.com/view/article/4476?docPos=10">ODNB</a>: Campbell wrote the work after reading Mandeville's <u>Fable of the Bees</u>, and in 1726 he entrusted the manuscript to Alexander Innes, who published the work under his own name. In 1730 Campbell asserted his authorship of the <u>Enquiry</u> in the "Advertisement" to his <u>Discourse Proving that the Apostles were no Enthusiasts</u>. In the 1733 republication of the <u>Enquiry</u>, Innes's duplicity was made public.
