Before you are the oldest treatises known to mankind on the art of war and its philosophy. Centuries and centuries have passed - however, to this day no one has yet been able to formulate the principles of the art of warfare as simply and aphoristically as did the classical “military philosophers” of Ancient China - people known to us only under the pseudonyms Sun Tzu and Wu Tzu .Before you are works that had a significant influence on the entire military art of the East - and to this day, are included in the training programs of military academies not only in China, but also in Japan. The treatises “Sun Tzu” and “Wu Tzu” are named after those ancient strategists to whom tradition ascribes the authorship, if not of these works themselves, then, in any case, of the positions expressed there. Both treatises are published in the classic translation of the remarkable orientalist N.I. Conrad and provided with extensive comments by the translator.
