What is logic and what is it good for? Starting from this question, this volume provides a fundamental introduction to elementary propositional and predicate logic. In addition to the logical rules, their interpretation and application, proof strategies and fallacies are also discussed and illustrated with examples. A comprehensive exercise section serves for targeted practice in using logical tools. Tailored to the mostly mandatory introductory logic courses in BA programs in philosophy. Additionally, the author explains the basic logical rules of elementary propositional logic (negation, disjunction, truth tables, etc.) and elementary predicate logic (universal quantifier, existential quantifier, proofs, etc.). The volume contains 14 exercise sheets for the individual chapters (without solutions) and 3 exam proposals (with solutions). Selling points: A fundamental and illustrative introduction to logic.
