The fundamentality of fields

There is debate as to whether quantum field theory is, at bottom, a of fields or particles. One can take approach the theory, using wave functionals over configurations, particle approach, functions configurations. This article argues for presenting three advantages approach: (1) are not available photons, (2) classical model electron gives superior account both spin and self-interaction compared model, (3) space appears be larger than functions. The also describes two important tasks facing proponents legitimize excise use Grassmann numbers fermionic values in functional amplitudes, describe how give rise particle-like behavior.
