For the reader who is not a philosopher and who has hitherto not made Aristotle's acquaintance may do well to by-pass temporarily the metaphysics. It is easier to understand him talking of the usefulness of organs in animal bodies, or of the differences between a brave man and a reckless one, or of the causes of revolution in states, or of the structure of a good play, than discoursing on the causes and nature of the universe being and existence as such. However, this book makes it easier for somebody coming to metaphysics for the first time. Nevertheless I personally would recommend reading some of Aristotle's work first before going into metaphysics. This book takes the reader through step by step as any good instructor should. I recommend this book to anyone who would consider reading or coming to metaphysics for the first time. I wouldn't be surprised to see this book at any university.
