“If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is temperamental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected .”

Chinese military general, strategist, philosopher and writer, Eastern Zhou period

Sun Tzu was a Chinese military general, strategist, philosopher, and writer from the Eastern Zhou period. He is traditionally credited with writing The Art of War, the classic Chinese treatise on military strategy. The work is associated with the Warring States period, although the earliest parts likely appeared at least a century after Sun Tzu. His name endures above all through this text, which has shaped how military strategy is discussed and studied.
