A quote
Think, too, of the famous Roman general; his soldiers had been dispatched to seize a position, and when they were about to make their way through a huge army of the enemy, he addressed them with the words: “You must go now, fellow-soldiers, to yonder place, whence there is no ’must’ about your returning!” You see, then, how straightforward and peremptory virtue is; but what man on earth can your deceptive logic make more courageous or more upright? Rather does it break the spirit, which should never be less straitened or forced to deal with petty and thorny problems than when some great work is being planned.
