We must now consider the manner in which prophetic knowledge is conveyed, and under this head there are four points of inquiry:
(1) Whether the prophets see God's very essence?
(2) Whether the prophetic revelation is effected by the infusion of certain species, or by the infusion of Divine light alone?
(3) Whether prophetic revelation is always accompanied by abstraction from the sense?
(4) Whether prophecy is always accompanied by knowledge of the things prophesied?
