1 The mind is not capable of understanding anything 2 higher than God, that is (I. Def. vi.), than a Being absolutely 3 infinite, and without which (I. xv.) nothing can either be or be 4 conceived; therefore (IV. xxvi. and xxvii.), the mind's highest 5 utility or (IV. Def. i.) good is the knowledge of God. Again, 6 the mind is active, only in so far as it understands, and only to 7 the same extent can it be said absolutely to act virtuously. The 8 mind's absolute virtue is therefore to understand. Now, as we 9 have already shown, the highest that the mind can understand is 10 God; therefore the highest virtue of the mind is to understand 11 or to know God. Q.E.D. 12 13
