"however little an intellect can grasp of divine knowledge, that little will be its ultimate end, rather than perfect knowledge of less intelligible things.
". . . to understand God in some way [(quoquo modo)] is man's ultimate end."
Intellectus . . . quantumcumque modicum possit de divina cognitione percipere, illud erit sibi pro ultimo fine, magis quam perfecta cognitio inferiorum intelligibilium.
. . . Est igitur ultimus finis hominis intelligere quoquo modo Deum.

"clearly the end of any intellectual creature, even the least, is to understand God" (n. 5).
