It's a comprehensive introduction to Aristotelian logic styled as a self-learning book complete with mini quizzes at the end of each chapter. There is an element of paradox in studying logic. The rules and mechanisms of logic are incredibly complex, or at least convoluted. A specialised vocabulary has to be established alongside the syllogistic framework which attempts to distill the form of discourse down its most basic parts. Yet through either our innate capacity for rationality and a well-rounded education, we can work through the processes without a framework or vocabulary and still arrive .
I slogged through the first half of the book which introduces the relevant concepts and terms; the word 'terms' itself, the word 'word' itself, the proposition, predicate, minor proposition, major proposition, antecedent, consequent, middle term, the conversion, obversion, contraversion, universal, particular, privative, moods, syllogisms etc. I think I put down the book for an entire month and almost gave up on it, wondering if formal logic was an exercise in pedantry.
When I picked it back up it was far less trying of course and I began to feel I was gaining something of value as I was able to read the text fluidly without having to constantly reference terms and work through the mechanics. The second half of the book I read in a day and I'd even say it was enjoyable. I now believe I have a far less transient understanding of inductive and deductive reasoning and hopefully access to a more precise means of refuting and synthesising knowledge.
