I am trying to read Lancaster and Blundell's Quantum Field Theory for the Gifted Amateur (OUP, 2014). I would be willing to accept quantum fields as the ultimate reality* if only there weren't the issues raised by general relativity. (see, for example, Monton's Against 3N-Dimensional Space in The Wave Function, Ney and Albert, OUP, 2013)
*"Therefore even matter itself is an excitation of a quantum field and quantum fields become the fundamental objects which describe reality." Lancaster and Blundell, page 2.
