In my opinion Bohr was more than a pragmatist. He made definite statements about the absence of a reality beneath quantum theory based not on a distaste for philosophy but using arguments drawn from the particular structure of quantum theory itself. All theories are pragmatic; some theories have a reality underneath. However, quantum theory is not a theory of this type, Bohr contends. As long as it keeps the form discovered by Heisenberg, Schrödinger, and Dirac, quantum theory will never be susceptible of reinterpretation in terms of a deeper reality.
