One of the main criticisms of classical political economy (including Quesnay...) and indeed of modern neoclassical economics is that they pretend not to have any normative content despite, for instance in the case of modern economists, a theory of value whose historical evolution was a direct response to the normative power of labour theories. It is a specific set of ideas in response to a social formation, and it's one reason so many economists are allergic to talking about medieval or ancient economies.
