A straightforward introduction to the subject that is easy to read and understand without oversimplification. Worthwhile.

It's witty and interesting, but ultimately too broad. You can't cover everything from Aristotle to the applications of logic in quantum computing in 200 pages. The section on neural networks was outstanding though, as was the section that broke down the Chomsky–Schützenberger hierarchy of formal languages.

because it was a graphic guide I assumed it would be easier to follow than other logic books but it is actually harder because the author explains the logic less well relying on the graphs for understanding.
