Being more familiar with a modern western diet of Platonic derived thinking, especially having the word "post-" prefix, this book came as a massive revelation and I cannot recommend it whole-heartedly enough as an accessible introduction.
It is a deceptively easy beginners guide to a brilliant mind that can lead you into more sound reading. I recommend Martha Nussbaum's 'The Fragility of Goodness: Luck and Ethics in Greek Tragedy and Philosophy', which devotes a whole section to delineating Aristotle's arguments, particularly his notion of appearances and inestimatable contribution to the subjects of ethics.
If you eventually get to thumb through more dense interpretations of Aristotle, or even Aristotle translated, the succinct points made in the Introducing Aristotle book should pop into mind and make a lot more sense, as well as offering a compass in navigating the size and scope of Aristotle's oeuvre. He labels many concepts to describe his practical wisdom, which this book goes some way to explaining. Though it might be said that a glossary of other terms would prove wonderfully useful - as the more you read the more you discover Aristotle to have an incredibly inventive penchant for subtley defining the human endeavour.
It is sometimes hard to fathom how someone who existed 400BC can still have a hold over modern philosophy, and reading Plato in conjunction with Aristotle would really set the classical paramaters of Western thought in the newly evolving sophos mind - as well as the maturing one!
The wonders of paradigm shifting that a love of wisdom can afford, and which come with perservence and effort, would be all the poorer without an understanding of Aristotle IMHO. Finally Aristotle is often accused of a remarked dryness in his style of delivery (possibly due to the only surviving works being lecture notes). However the book's visual narrative helps to lighten the understanding somewhat...
