   • 1667, John Milton, Paradise Lost‎:

     […] in at his mouth
     The Devil entered; and his brutal sense,
     In heart or head, possessing, soon inspired
     With act intelligential; but his sleep
     Disturbed not, waiting close the approach of morn.

   • 1814, The Rev. H. F. Cary, M.A., The Vision of Paradise, Part 3.‎:

     Nor demonstration physical alone,
     Or more intelligential and abstruse,
     Persuades me to this faith; but from that truth
     It cometh to me rather, which is shed
     Through Moses, the rapt Prophets, and the Psalms.

   • 1918, Henry A. Beers, A History of English Romanticism in the Nineteenth Century‎:

     In the line of light bringers who pass from hand to hand the torch of intelligential fire, there are men of most unequal stature, and a giant may stoop to take the precious flambeau from a dwarf.
