A good read on Classical Logic aka Formal Logic. Beneficial for those already verbosed in Manțīq as it conveys you all the equivalent terms in Latin/Greek that which you already know in Arabic, and for those who are about to aboard the discipline as it teaches you all that you need.
One good features about it is that, Luce always draw us back to Aristotle so as to elucidate us about what he has in mind when he speaks about things. The book does not just prescribe you the rules but argues why the rules are true. Having said that, some criticism upon Aristotle are also shed. Aristotle is after everything else, is just a man who errs and with shortcomings.
The book did poorly to introduce us to Symbolic Logic which is in my opinion is what ought to be studied now, but nevertheless such a discipline was not in Luce attention to expound on.
As usual, I skip all the Moods and Forms part for it is too pedantic to me. I might have to look it up again in order to eventually complete my understanding on Logic.
The book is pretty much readable. Luce intended that this book be a self-help (hence the title). There are questions to test your understanding at the end of every chapter.
