Memorabilia

If any man thinks that these matters are wholly within the grasp of the human mind and nothing in them is beyond our reason, that man, he said, is irrational. But it is no less irrational to seek the guidance of heaven in matters which men are permitted by the gods to decide for themselves by study: to ask, for instance, Is it better to get an experienced coachman to drive my carriage or a man without experience?[*](Cyropaedia I. vi. 6.) Is it better to get an experienced seaman to steer my ship or a man without experience? So too with what we may know by reckoning, measurement or weighing. To put such questions to the gods seemed to his mind profane. In short, what the gods have granted us to do by help of learning, we must learn; what is hidden from mortals we should try to find out from the gods by divination: for to him that is in their grace the gods grant a sign.
