“Therefore, just as water retains no constant shape, so in warfare there are no constant conditions.”

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.
