Useful and honourable. Notes towards a philosophy of political economy in the Traict?

Montchr?tien set off in pursuit of a solution to the complex problem of the relationship between economics and politics, inherent to the sovereign?s task of modifying the laws according to the needs, and working on the aspects regarding the health and conservation of the State. If what is "useful" for the city is the true end of reasonable policy (of raison d??tat), then is it to be a matter of reaffirming the Ciceronian viewpoint, the "useful" and the "honourable" being inseparable, as Aristotle taught in the seventh book of Politics? Montchr?tien seems to follow the reflections of Bonaventura, according to whom the useful which does not abandon the honourable, pursued and conserved from raison d??tat, is that which seeks to preserve the city in well-being not only from the inevitable decay of time (the body politic ages, just like the natural and animal body) but to conserve it with a view to the health of the social body, to which all the efforts of the nation should be directed, becoming the sort of collective subject, much like seamen aboard a ship with different tasks serving one common purpose.
