José de Acosta

“Much of what he says is of necessity erroneous, because it is influenced by the standard of knowledge of his time; but his criticisms are remarkable, while always dignified. He reflects the scientific errors of the period in which he lived, but with hints of a more advanced understanding.”

“Apart from his sophistical defence of Spanish colonial policy, Acosta deserves high praise as an acute and diligent observer whose numerous new and valuable data are set forth in a vivid style.”

“Let no man thinke (speaking of the Indians,) that they are men of nothing; but if they thinke so, let them go and make triall.”
