The Joy Of Abstraction by Eugenia Cheng

An Exploration of Math, Category Theory, and Life

A friendly introduction to abstraction through category theory, showing how focusing on structures and relationships—objects and arrows, composition, functors, and natural transformations—unifies diverse areas of mathematics and clarifies everyday reasoning. Using clear analogies and accessible examples, it demystifies proof and rigor, highlights universal properties and recurring patterns, and encourages readers to value conceptual understanding and generalization over rote computation.
