Whether pertinacity is opposed to perseverance?

❌ Objection 1 : It seems that pertinacity is not opposed to perseverance. For Gregory says (Moral. xxxi) that pertinacity arises from vainglory. But vainglory is not opposed to perseverance but to magnanimity, as stated above (Question [132], Article [2]). Therefore pertinacity is not opposed to perseverance.

❌ Objection 2 : Further, if it is opposed to perseverance, this is so either by excess or by deficiency. Now it is not opposed by excess: because the pertinacious also yield to certain pleasure and sorrow, since according to the Philosopher (Ethic. vii, 9) "they rejoice when they prevail, and grieve when their opinions are rejected." And if it be opposed by deficiency, it will be the same as effeminacy, which is clearly false. Therefore pertinacity is nowise opposed to perseverance.

❌ Objection 3 : Further, just as the persevering man persists in good against sorrow, so too do the continent and the temperate against pleasures, the brave against fear, and the meek against anger. But pertinacity is over-persistence in something. Therefore pertinacity is not opposed to perseverance more than to other virtues.
