Man's second nature

Pedagogy is the art of making men ethical. It looks upon man as natural, and points out the way in which he is to be born again. His first nature must be converted into a second spiritual nature, in such a manner that the spiritual becomes in him a habit.

Exegesis

As Dante explained in the Epistula XIII, given a verse such as in exitu Israel de Aegypto, "if we look at the letter it means the exodus of the sons of Israel from Egypt at the time of Moses; if we look to the allegory it means our redemption through Christ; if we look at the moral sense it means the conversion of the soul from the misery of sin to the state of grace; if we look at the mystical sense it means the departure of the sanctified spirit from the servitude of this corruption to the freedom of eternal glory."
(Eco, Semiotics and philosophy of language, p. 149)
