Book Description

If you’ve ever wondered what makes mathematical logic tick but felt overwhelmed by dense textbooks, A Friendly Introduction to Mathematical Logic is your new best friend. Authored by Christopher C. Leary and Lars Kristiansen, this book takes you on a journey from the basics of first-order logic all the way to Gödel’s incompleteness theorems and computability theory. The writing is approachable and the pace is just right for a single semester or a motivated self-learner.

The authors skip the usual propositional logic intro and dive straight into predicate logic, saving you time for deeper topics like model theory and recursion. Each chapter builds logically (pun intended!) on the last, making even complex ideas feel manageable. Whether you’re a math major, a philosophy student with an interest in logic, or just someone who loves puzzles and proofs, you’ll find this book both enlightening and surprisingly enjoyable.

While it doesn’t cover every aspect of mathematical logic (sorry, modal logic fans), it does an excellent job with the essentialssoundness, completeness, compactness, incompleteness, and computability. Plus, there are plenty of exercises to test your understanding along the way.

What You Will Learn

• The fundamentals of first-order mathematical logic
• How languages, structures, and deductions interact
• The Soundness and Completeness Theorems
• The Compactness Theorem
• Gödel’s First and Second Incompleteness Theorems
• Basics of model theory (with fun detours like the Löwenheim-Skolem Theorems)
• Introduction to computability theory
• How to code sequences of numbers using logic
• Practical exercises to reinforce each concept

This book is perfect for undergraduate students taking their first course in mathematical logic. It’s also great for autodidacts who want a structured path through core logical concepts without getting lost in jargon. Even instructors will appreciate its clear explanations and thoughtful progression.
