Open your mind to what I shall disclose, and hold it fast within you; he who hears, but does not hold what he has heard, learns nothing. Beatrice - Canto V 40-42
The mind which is created quick to love, is responsive to everything that is pleasing, soon as by pleasure it is awakened into activity. Your apprehensive faculty draws an impression from a real object, and unfolds it within you, so that it makes the mind turn thereto. And if, being turned, it inclines towards it, that inclination is love; that is nature, which through pleasure is bound anew within you.
Those ancients who in poetry presented the golden age, who sang its happy state, perhaps, in their Parnassus, dreamt this place. Here, mankind's root was innocent; and here were every fruit and never-ending spring; these streams--the nectar of which poets sing.
