Category theory is a general mathematical theory of structures and of structures of structures. It occupied a central position in contemporary mathematics as well as computer science. This book describes the history of category theory whereby illuminating its symbiotic relationship to algebraic topology, homological algebra, algebraic geometry and mathematical logic and elaboratively develops the connections with the epistemological significance.
The clear self-diagnosis of his historiographical methods and philosophical implications of this work were interesting. Would not recommend this book unless you are fluent in homological algebra, category theory, homotopy analysis, sheaf theory, and set theory. An extremely technical read.
