The confidently theoretical method of English classical economics is t
raced to the Enlightenment's struggle to resolve the disputes between
rationalism and anti-rationalism which had dominated the 17th century.
it is argued that, in an attempt to resolve these disputes, several E
nlightenment authors, including David Hume and Dugald Stewart, sought
to unite empiricism with the notion of law-like universe by arguing th
at economic laws are no more than general facts apparent from everyday
life. This position, by denying that theory had any connection with t
he hypothetical, the instrumental or the abstract, blurred the distinc
tion between theory and fact, and taught Classical economists to see t
heir theorising as fact. This position thereby gave the Classical econ
omists licence to pursue their theoretical speculations, free from any
doubts or uncertainties about their theorising.
