Dear List, here is my newly published monograph on the history and philosophy of category theory and some other related matters: http://www.springer.com/philosophy/book/978-3-319-00403-7 http://www.amazon.com/Axiomatic-Method-Category-Synthese-Library/dp/33190040... The main thesis of the book: Categorical logic brings us back to Euclid leaving Hilbert at the margins (I'm talking here about Hilbert's version of axiomatic method, not about his legacy as a whole). Table of Contents (Category theory doesn't appear in the book before Chapter 4): Introduction.- Part I A Brief History of the Axiomatic Method.- Chapter 1. Euclid: Doing and Showing.- Chapter 2. Hilbert: Making It Formal.- Chapter 3. Formal Axiomatic Method and the 20th Century Mathematics.- Chapter. 4 Lawvere: Pursuit of Objectivity.- Conclusion of Part 1.- Part II. Identity and Categorification.- Chapter 5. Identity in Classical and Constructive Mathematics.- Chapter 6. Identity Through Change, Category Theory and Homotopy Theory.- Conclusion of Part 2.- Part III. Subjective Intuitions and Objective Structures.- Chapter 7. How Mathematical Concepts Get Their Bodies. Chapter 8. Categories versus Structures.- Chapter 9. New Axiomatic Method (instead of conclusion).- Bibliography.​ A draft version is on arXiv. I hope some of you may enjoy it and I'll be most grateful for any critique and any comment. best regards, AR [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
