This is a well-written elementary introduction to logic, particularly suitable for students in the humanities, but also accessible for interested high school students. Always there are lots of examples and exercises.
The book starts with a broad propaedeutics focussing on aspects of the extraction of the logical content of common language sentences. The main part presents propositional as well as first-order logic, including identity logic and definite descriptions, but also an interesting discussion of syllogisms. At the end there is a concise explanation of logics of modalities: alethic, deontic, and also epistemic ones.
For each logic a tableau method is explained and a Hilbert-type calculus sketched. For classical logic, additionally, a natural deduction system is given. All the necessary details are provided, but general results are only mentioned and not proved.
