To Archidamus (59)

For my part, I consider that the strongest and surest ally we can have is just dealing, for it is probable that the favor of the gods will be with those who deal justly—that is, if we may judge the future by the past; and in addition to this ally are good government and sober habits of life, and a willingness to battle to the death against the enemy, and the conviction that nothing is so much to be dreaded as the reproaches of our fellow-citizens—qualities which we possess in larger measure than any other people in existence.
