Reply to Objection 3: A man does not expose his person to dangers of death except in order to safeguard justice: wherefore the praise awarded to fortitude depends somewhat on justice. Hence Ambrose says (De Offic. i) that "fortitude without justice is an occasion of injustice; since the stronger a man is the more ready is he to oppress the weaker."
The Fourth argument is granted.
Reply to Objection 5: Liberality is useful in conferring certain particular favors: whereas a certain general utility attaches to fortitude, since it safeguards the whole order of justice. Hence the Philosopher says (Rhet. i, 9) that "just and brave men are most beloved, because they are most useful in war and peace."
