As a personal injury lawyer I am attempting to resolve various conflicts every day. I have found "The Art of War" to be one of the best books on strategy and understanding your opponent. It was written almost 2,500 years ago by Sun Tzu, a Chinese military strategist. While the chapters on how to handle carts, oxen, swords and spears is irrelevant to the modern era, his thoughts on how to resolve conflict short of war are genius. I use his teachings every day in my law practice. Although, as the title says, it is a discussion of war tactics, it provides way more than the title would have you believe. For those just learning about game theory, I strongly recommend this read. It is unfortunate the use of the word "Game" in the term "Game Theory" implies that it is frivolous or unimportant. The reality is game theory is being used to negotiate nuclear arms treaties and resolve trade disputes between nations. Our standard of living and our very survival is dependent on how well our people in government understand the underlying principles of game theory. Thanks @aydogdy for bringing this very important subject to light.
