 Further Reading on QFT and Philosophy of QFT. Mandl and Shaw (2010), Peskin and Schroeder (1995), Weinberg (1995) and Weinberg (1996) are standard textbooks on QFT. Teller (1995) and Auyang (1995) are the first systematic monographs on the philosophy of QFT. The anthologies Brown and Harré (1988), Cao (1999) and Kuhlmann et al. (2002) are anthologies with contributions by physicists and philosophers (of physics), the last of which focuses on ontological issues. The literature on the philosophy of QFT has increased significantly in the last decade. Besides several papers there are a few new monographs, Cao (2010), Kuhlmann (2010), Ruetsche (2011) and Duncan (2012) and a special issue (May 2011) of Studies in History and Philosophy of Modern Physics. Bain (2011), Huggett (2000), Ruetsche (2002) and Swanson (2017) provide article length discussions on a number of issues in the philosophy of QFT.
