Whether there can be intellectual without moral virtue?

❌ Objection 1 : It would seem that there can be intellectual without moral virtue. Because perfection of what precedes does not depend on the perfection of what follows. Now reason precedes and moves the sensitive appetite. Therefore intellectual virtue, which is a perfection of the reason, does not depend on moral virtue, which is a perfection of the appetitive faculty; and can be without it.

❌ Objection 2 : Further, morals are the matter of prudence, even as things makeable are the matter of art. Now art can be without its proper matter, as a smith without iron. Therefore prudence can be without the moral virtue, although of all the intellectual virtues, it seems most akin to the moral virtues.

❌ Objection 3 : Further, prudence is "a virtue whereby we are of good counsel" (Ethic. vi, 9). Now many are of good counsel without having the moral virtues. Therefore prudence can be without a moral virtue.
