Whether security belongs to magnanimity?

Objections

Objection 1 : It seems that security does not belong to magnanimity. For security, as stated above (Question [128], ad 6), denotes freedom from the disturbance of fear. But fortitude does this most effectively. Wherefore security is seemingly the same as fortitude. But fortitude does not belong to magnanimity; rather the reverse is the case. Neither therefore does security belong to magnanimity.
Objection 2 : Further, Isidore says (Etym. x) that a man "is said to be secure because he is without care." But this seems to be contrary to virtue, which has a care for honorable things, according to 2 Tim. 2:15, "Carefully study to present thyself approved unto God." Therefore security does not belong to magnanimity, which does great things in all the virtues.
Objection 3 : Further, virtue is not its own reward. But security is accounted the reward of virtue, according to Job 11:14,18, "If thou wilt put away from thee the iniquity that is in thy hand . . . being buried thou shalt sleep secure." Therefore security does not belong to magnanimity or to any other virtue, as a part thereof.
