Sun Tzu was a human philosopher on Earth from China, who lived in the 2nd century BC. Sun Tzu is best known for his influential text The Art of War, which was required reading at Starfleet Academy. (TNG episode: "The Last Outpost")
Immediately prior to the Battle of Xahea, Commander Saru paraphrased Sun Tzu when he said, "Be extremely subtle, even to the point of formlessness. Be extremely mysterious, even to the point of soundlessness." The mirror universe Philippa Georgiou completed the quote, "Thereby you can be the director of your opponent's fate." Saru was surprised that the mirror Georgiou knew of Sun Tzu (DSC episode: "Such Sweet Sorrow, Part II")
One of Sun Tzu's noted sayings – "If you know your enemy and know yourself, you need not fear the result of a hundred battles" – had also been attributed to Kahless the Unforgettable. Klingon Captain Kang was impressed to learn any human could have possessed such insight into the art of war. (TOS - Mere Anarchy eBook: The Blood-Dimmed Tide)
