It's a book. I'm not going to say whether its contents are correct or incorrect; just or unjust; terrible or benevolent--it's not my job to tell anyone what to think about this book or whether or not to read it. It is a book that has influenced many people after its publication and still grips the political thinking of many people today. It is an influential book--and thus, an important book. But I cannot say--because saying would be telling and I don't intend to tell anyone what to think or believe--if this book represents the truth and I must remind everyone that this book, like many books, may be inaccurate, biased, and narrow-sighted. This book, like many books, may well also be enlightened, truthful, and prophetic. But it's not my job to tell you which one you should believe in.
I will also tell you though, that books of this kind are rarely written for leisure. They are rarely written with indifference and they are rarely indifferent about what their readers think about them; books like these have purposes and goals and agendas. A book like this exists to convince and argue. It is not here to tell a story for the sake of leisurely story.
This is not to say that you shouldn't read it, but to say that readers must understand that this book is not without its biases; that this book is written from a perspective that is by no means objective--even if it is a valid perspective; that this book, like all books, must be carefully approached and analyzed, its premises investigated, and its truth status determined. We must not let this--or any--book take us by surprise in a moment of docility. The writers of this book wish for us to think, to be active, to question...and I am sure the authors expect its readers to do the same toward this book.
