The Art of Logic in an Illogical World

Eugenia Cheng examines the boundary between mathematical certainty and human emotion by applying formal logic to contemporary social issues. She explains how to construct valid arguments using tools like truth tables, axioms, and category theory while highlighting where logical rigor hits its limit. Cheng addresses why smart people disagree on topics like privilege, sexism, and social justice by identifying divergent starting assumptions rather than faulty deductions. She demonstrates that while logic can expose inconsistencies and simplify complex problems, it requires a foundation of empathy to handle the nuance of real-world interactions.

This book is for readers who find online discourse or political arguments frustratingly circular. It serves those interested in analytical philosophy and mathematics who want to apply those disciplines to daily life. Readers gain a framework for identifying logical fallacies in others and uncovering their own hidden biases. After reading, a person walks away with a toolkit for deconstructing complex disagreements into their basic parts, allowing them to communicate more clearly and understand the root causes of conflicting viewpoints without abandoning rational thought.
