 Today, many philosophers of physics who work on QFT rest most of their considerations on AQFT. This predominance of AQFT for foundational studies about QFT becomes problematic, however, when AQFT is seen as a physical theory in competition to Conventional QFT (CQFT). Wallace (2006, 2011) even urges that, seen from today, CQFT succeeded, whereas AQFT failed, so that “to be lured away from the Standard Model by [AQFT] is sheer madness” (Wallace 2011:124). Contra Wallace, Fraser (2011) questions Wallace’s crucial point in defense of CQFT, namely that the application of renormalization group techniques in QFT finally solved the problem of ultraviolet divergences that troubled CQFT in the 1950s. The empirical success of renormalization in CQFT leaves the physical reasons for this success in the dark, argues Fraser, unlike in condensed matter physics, where its success is due to the fact that matter is discrete at atomic length scales.
