Context

“On the other hand, the object of the intellectual and moral virtues is something comprehensible to human reason. Wherefore the theological virtues are specifically distinct from the moral and intellectual virtues. Reply Obj. 1: The intellectual and moral virtues perfect man's intellect and appetite according to the capacity of human nature; the theological virtues, supernaturally. Reply Obj. 2: The wisdom which the Philosopher (Ethic. vi, 3, 7) reckons as an intellectual virtue, considers Divine things so far as they are open to the research of human reason.” source
