If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.” ~ Sun Tzu (c.500-320 B.C.) name used by the unknown Chinese authors of the sophisticated treatise on philosophy, logistics, espionage, strategy and tactics known as 'The Art of War'
