Where to Gather Intelligence by Sun Zi
English: This foreknowledge cannot be obtained from the spirits nor from the gods. It cannot be obtained by comparing with similar present or past events and situations. Neither can it be obtained from the study of astrology. This foreknowledge must be obtained from men who have knowledge of the situation of the enemy.
Modern: 要事先了解敌情，并非祈求鬼神取得，并非用相似的事做推测，也并非观察日月星辰运行来验证，而是取于了解敌情的人。
Original: 先知者不可取于鬼神，不可象于事，不可验于度，必取于人，知敌之情者也。
