Feijoo's Mapa intelectual y cotejo de naciones (Teatro critico, discourse XV)

The discourse in which a Benedictine in Oviedo argues that no nation holds a monopoly on intelligence — and devotes its American section to demolishing the idea that the Indians were governed by instinct rather than reason. Its sharpest line answers the story of gold traded for glass beads: whoever judges them coarse for that is coarser than they are. Read here in the Madrid 1765 printing of the second tome, whose censura is dated 1728.
