 Ultimately, the most reasonable position may be a liberal one, according to which neither of the three, AQFT, Wightman’s field axiomatics and CQFT, should be regarded as rival research programs, only one of which can and should survive (Kuhlmann 2010b, Swanson 2017). Wightman’s Axiomatic QFT is fruitful in the construction of concrete models, AQFT is advantageous for ontological considerations because it clearly separates fundamental and derived entities, and CQFT is very good for actual calculations of the high energy physicist.
