"Even the Mercantile System cannot be correctly judged by modern economics since the latter is itself one-sided and as yet burdened with that very system’s premises. Only that view which rises above the opposition of the two systems, which criticises the premises common to both and proceeds from a purely human, universal basis, can assign to both their proper position. It will become evident that the protagonists of free trade are more inveterate monopolists than the old Mercantilists themselves. It will become evident that the sham humanity of the modern economists hides a barbarism of which their predecessors knew nothing; that the older economists’ conceptual confusion is simple and consistent compared with the double-tongued logic of their attackers, and that neither of the two factions can reproach the other with anything which would not recoil upon themselves. This is why modern liberal economics cannot comprehend the restoration of the Mercantile System by List, whilst for us the matter is quite simple. The inconsistency and ambiguity of liberal economics must of necessity dissolve again into its basic components. Just as theology must either regress to blind faith or progress towards free philosophy, free trade must produce the restoration of monopolies on the one hand and the abolition of private property on the other."
