The concept "Homo economicus" had specific problems being interwoven into the new-found economic process of the 18th century. Foucault manages to trace this anomaly through the subject of right (known as consent of the governed the theory of right of that legal theorists of the 18th century tried to establish during their legal discourse) which did receive a great deal of attention because of what was perceived at the time of problems regarding the sovereign's power. The subject of right had to perform slight modifications because of the implication of him (the subject of right) limiting the sovereign's power. Which certainly differed from classical liberalism's conception of the sovereign power, which from the 16th century was conceived of as impenetrable to any rational discourse. The sovereign was conceived of as absolute, but the discovery of the people, subject of rights, homo oeconomicus, changed all that because of the arrival of market practices (the market system of capitalism) from the 18th century. Even the Physiocrats insisted that the market, the sovereign had to really respect the market.
