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.
