That Happiness does not consist in the Knowledge of God by Faith

HAPPINESS is the perfect activity of the human intellect (Chap. XXVI). But in the knowledge that is of faith, though there is high perfection on the part of the object so apprehended, there is great imperfection on the side of intellect, for intellect does not understand that to which it assents in believing.

2. Final happiness does not consist principally in any act of will (Chap. XXVI). But in the knowledge of faith the will has a leading part: for the understanding assents by faith to the things proposed to it, because it wills to do so, without being necessarily drawn by the direct evidence of truth.

3. He who believes, yields assent to things proposed to him by another, which himself he does not see: hence the knowledge of faith is more like hearing than seeing. Since then happiness consists in the highest knowledge of God, it cannot consist in the knowledge of faith.

4. Happiness being the last end, all natural desire is thereby appeased. But the knowledge of faith, far from appeasing desire, rather excites it, since every one desires to see that which he believes.
