Whether the subject of pride is the irascible faculty?

Objections

Objection 1 : It would seem that the subject of pride is not the irascible faculty. For Gregory says (Moral. xxiii, 17): "A swollen mind is an obstacle to truth, for the swelling shuts out the light." Now the knowledge of truth pertains, not to the irascible but to the rational faculty. Therefore pride is not in the irascible.
Objection 2 : Further, Gregory says (Moral. xxiv, 8) that "the proud observe other people's conduct not so as to set themselves beneath them with humility, but so as to set themselves above them with pride": wherefore it would seem that pride originates in undue observation. Now observation pertains not to the irascible but to the rational faculty.
Objection 3 : Further. pride seeks pre-eminence not only in sensible things, but also in spiritual and intelligible things: while it consists essentially in the contempt of God, according to Ecclus. 10:14, "The beginning of the pride of man is to fall off from God." Now the irascible, since it is a part of the sensitive appetite, cannot extend to God and things intelligible. Therefore pride cannot be in the irascible.
Objection 4 : Further, as stated in Prosper's Liber Sententiarum, sent. 294, "Pride is love of one's own excellence." But love is not in the irascible, but in the concupiscible. Therefore pride is not in the irascible.
