Teuton wrote:"On this background, Teller has argued in Teller 1995 that the field interpretation of QFT is inappropriate since the alleged fields in QFT are not to be interpreted as physical fields with definite values of some sort which are assigned to space-time points, like in the case of the classical electromagnetic field."

Nice, so Teller is an example of a quantum field non-realist, a point of view not being represented on this thread :grin:

Teuton wrote:Does this mean that operators represent the range of all possible determinate properties of a determinable quantity that can be possessed by a spacetime point? But how could an actual physical field be a collection of merely possible properties? Is it possible at all for there to be indeterminate physical properties in physical reality? For example, is it possible to have a mass without having a determinate mass?

Is your gripe here with non-determinism? Do you find it unacceptable that a physical quantity might not be thought of as a definite value, but instead as a range of possible values, each with a different probability?
