I am looking for an introductory book on QFT which is relatively self-contained.
Aims:
Useful for philosophers interested in Philosophy of Science (but Mostly math-oriented)
If such a book simply does not exist, I would equally appreciate multiple books that answers the question.
Shankar's QM book does what I intend but for QM. Perhaps a book like Shankar's would be perfect.
Jakob Schwichtenberg has written a book called No-Nonsense Quantum Field Theory. While I haven't read this one, I've read other books by the same author in the same series and they're great.
If you're looking for a philosophy of science approach, Weinberg's The Quantum Theory of Fields is a classic textbook that examines why QTF is the way it is. It builds up the theory from fundamental ideas. It also has a chapter on the history of the field. It is pretty mathematically advanced though, so it might not be the best introduction.
