When it comes to morality and ethics, people are used to thinking in terms of black and white. Conversely, "The 48 Laws of Power" deals primarily with the gray areas. At the risk of sounding melodramatic and trite, I say that most of the Laws covered in this book can be used for great evil or for great good. It depends on the reader. There is really nothing wrong with most of the Laws per se.
Each Law comes with true stories from history about those who successfully observed it and those who foolishly or naively trangressed it. Robert Greene has an interpretation for each story. Though each Law is self-explanatory, Greene's explanations are not padding, fluff or stuffing to make the book longer. They actually give greater clarification and depth. Greene's insight even extends to crucial warnings about how the Laws could backfire.
There are two reasons to read this book:
1. For attack: To gain power, as have others who have carefully observed the Laws;
2. For defense: To be aware of ways that people may be trying to manipulate you.
As Johann von Goethe said (as quoted in "The 48 Laws of Power", of course): "The only means to gain one's ends with people are force and cunning. Love also, they say, but that is to wait for sunshine, and life needs every moment."
Those who say they have never used any of these laws are either being hypocritical--or lying.
