Political economy and the 'modern view' as reflected in the history of economic thought

This paper focuses on the transition from classical political economy to modern' economics, a central aspect of which is the ascent of the conception of theory' as a mere instrument of research. We analyse how this transitional phase was perceived and interpreted in representative, more or less contemporaneous histories of economic thought: those by Luigi Cossa in 1880, by John Kells Ingram in 1915 (originally published in 1888), and by Charles Gide and Charles Rist in 1915. Despite their differences, all authors share the same conception of the structure of scientific laws, as well as the view that economics must be separated from liberalism.
