Juan Luis Vives original: "Lud. Vives"; referring to the influential Spanish Renaissance humanist (1493–1540).

Nature is not to be examined by the Lamp of the Gentiles Gentiles: Here referring to the non-Christian, classical Greek and Roman philosophers, specifically Aristotle., which yields a light that is both dim and unreliable; instead, it must be examined by the Torch of the Sun, which Christ has brought into the darkness of the World. And for that very reason, we have had cause to write, so that we should not be forced to follow the traditions of the Gentiles; between whom and us there is such a vast difference in Religion. And to tell the truth, just as Aristotle's writings have much learning and cleverness, they also have very much obscurity. This has given some people the opportunity to search for—and imagine they see—those things which do not actually exist, etc.
