Context

“2: Since fear is born of love, any virtue that moderates the love of certain goods must in consequence moderate the fear of contrary evils: thus liberality, which moderates the love of money, as a consequence, moderates the fear of losing it, and the same is the case with temperance and other virtues. But to love one's own life is natural: and hence the necessity of a special virtue modifying the fear of death. Reply Obj. 3: In virtues the extreme consists in exceeding right reason: wherefore to undergo the greatest dangers in accordance with reason is not contrary to virtue. _______________________
