Written over two thousand years ago, The Art of War contains penetrating insights into the nature of power, inter-state rivalry, realpolitik and military success, relevant to any age. It was first translated into English in the early 20th century. Sun Tzu's short lines of argument and pithy aphorisms are highly accessible to modern readers, and his text has almost achieved cult status. He is quoted everywhere 'from divorce courts to Facebook', and has something to offer anyone interested in honing leadership skills and achieving in any competitive environment 'from the boardroom to the bedroom'. Sun Tzu's advice is shrewd and pragmatic - he does not glory in slaughter and prefers to win battles off the battlefield if possible; he is a strong supporter of the use of deception, of varying your shots and above all, of doing your research: knowing your enemy is key; but of little use if you do not also 'know yourself'.
