Whether anger is a special passion?

Objections

Objection 1 : It would seem that anger is not a special passion. For the irascible power takes its name from anger [ira]. But there are several passions in this power, not only one. Therefore anger is not one special passion.
Objection 2 : Further, to every special passion there is a contrary passion; as is evident by going through them one by one. But no passion is contrary to anger, as stated above (Question [23], Article [3]). Therefore anger is not a special passion.
Objection 3 : Further, one special passion does not include another. But anger includes several passions: since it accompanies sorrow, pleasure, and hope, as the Philosopher states (Rhet. ii, 2). Therefore anger is not a special passion.
