Reason then is literally a revelation, a necessary and universal revelation, which is wanting to no man and which enlightens every man on his coming into the world: _illuminat omnem hominem venientem in hunc mundum_. Reason is the necessary mediator between God and man, the [Greek: logos] of Pythagoras and Plato, the Word made flesh which serves as the interpreter of God and the teacher of man, divine and human at the same time. It is not, indeed, the absolute God in his majestic individuality, but his manifestation in spirit and in truth; it is not the Being of beings, but it is the revealed God of the human race.
