Here is how Saint Thomas Aquinas states that thought, intellectually, regarding the supreme heights of the intellectual realm.
De rebus nobilissimis quantumcumque imperfecta cognitio maximam perfectionem animae confert. Et ideo, quamvis ea quae supra rationem sunt ratio humana plene capere non possit, tamen multum sibi perfectionis acquiritur si saltem ea qualitercumque teneat fide.
However imperfect the knowledge of the noblest things may be, it bestows very great perfection to the soul. And consequently, although human reason is unable to fully grasp things above reason, it nevertheless acquires much perfection if at least it hold things, in any way whatever, by faith.
