But this clearly is not the case: since there is one moral virtue about contrary passions; namely, fortitude, about fear and daring; temperance, about pleasure and sorrow. Therefore there is no need for different moral virtues about different passions.

“Therefore there is but one moral virtue about all the passions.
Obj. 2: Further, if there were different moral virtues about different passions, it would follow that there are as many moral virtues as passions. But this clearly is not the case: since there is one moral virtue about contrary passions; namely, fortitude, about fear and daring; temperance, about pleasure and sorrow. Therefore there is no need for different moral virtues about different passions. Obj. 3: Further, love, desire, and pleasure are passions of different species, as stated above (Q. 23, A. 4). Now there is but one virtue about all these three, viz. temperance. Therefore there are not different moral virtues about different passions.
