A great read. Read for personal research. Overall, a good book for the researcher and enthusiast. I found this book's contents helpful and inspiring - number rating relates to the book's contribution to my needs. “The king of Qin, with his arched nose and long eyes, puffed-out chest like a hawk and voice of a jackal, is a man of scant mercy who has the heart of a tiger or a wolf. When he is in difficulty he readily humbles himself before others, but when he has gotten his way, then he thinks nothing of eating others alive. I am a mere commoner, yet when he receives me he always acts as though he were my inferior. But if the king of Qin should ever get his way with the world, then the whole world will end up his prisoner. It doesn't do to stay around a man like that for long!”
