Maharbal mg on the intellectual victory of the Keynesians:
[It is] more like Hannibal at Cannae: a brilliant victory that caused a few people to switch sides, but still not changing the ultimate outcome of the war itself. Obama and Bernanke are the modern analogue of the Carthaginian oligarchy: sitting on their hands, rather than following up a crushing win with enough resources and support to finish the job.
Livy, History of Rome, 22.51
When all others, surrounding the victorious Hannibal, congratulated him, and advised that, having completed so great a battle, he should himself take the remainder of the day and the ensuing night for rest, and grant it to his exhausted troops; Maharbal, prefect of the cavalry, who was of opinion that no time should be lost, said to him, "Nay, rather, that you may know what has been achieved by this battle, five days hence you shall feast in triumph in the Capitol. Follow me: I will go first with the cavalry, that they may know that I am arrived before they know of me as approaching."
To Hannibal this project appeared too full of joy, and too great for his mind to embrace it and determine upon it at the instant. Accordingly, he replied to Maharbal, that "he applauded his zeal, but that time was necessary to ponder the proposal."
Upon this Maharbal observed, "Of a truth the gods have not bestowed all things upon the same person. You know how to conquer, Hannibal; but you do not know how to make use of your victory."
That day's delay is firmly believed to have been the preservation of the city and the empire…
