Whether there can be moral without intellectual virtue?

❌ Objection 1 : It would seem that moral can be without intellectual virtue. Because moral virtue, as Cicero says (De Invent. Rhet. ii) is "a habit like a second nature in accord with reason." Now though nature may be in accord with some sovereign reason that moves it, there is no need for that reason to be united to nature in the same subject, as is evident of natural things devoid of knowledge. Therefore in a man there may be a moral virtue like a second nature, inclining him to consent to his reason, without his reason being perfected by an intellectual virtue.

❌ Objection 2 : Further, by means of intellectual virtue man obtains perfect use of reason. But it happens at times that men are virtuous and acceptable to God, without being vigorous in the use of reason. Therefore it seems that moral virtue can be without intellectual.

❌ Objection 3 : Further moral virtue makes us inclined to do good works. But some, without depending on the judgment of reason, have a natural inclination to do good works. Therefore moral virtues can be without intellectual virtues.
