Abstract

Nick Huggett, James Ladyman, and Karim Thébault (HLT) have presented a comprehensive article examining the Born-Oppenheimer Approximation (BOA). Their central objective is to challenge our position on the matter—namely, that the BOA incorporates a classical assumption incompatible with the Heisenberg Uncertainty Principle. In contrast, HLT contend that the BOA involves no such classical assumption and, as a result, supports the view that chemistry can be reduced to physics. The purpose of this paper is to offer a critical analysis of the HLT article and to clarify why we consider their arguments unpersuasive.
