This book was written by an ancient chinese general., Sun Tzu and has over time been translated by many differnet people in many different languages. I read the Samuel Griffin translation which I think was good and offers a massive introduction to full understand the historical context of the writing and the life of the writer, and also offers different translations of verses. The book is no doubt an attempt to make a science of war, and lays out a manual for a succesful military operation.
My biggest complaint about the book is how military focused it is, but along the way you will still find some great morsels that can be applied to various other aspects of life like taking the path of least resistance or to be like water, just as water has no constant form their are no constant conditions in life or in war
