Abstract
In contemporary philosophy of science many theories of explanation are rooted in positivist or post-positivists accounts of explanation. This paper attempts to ground a phenomenological account of scientific explanation by using the works of Werner Heisenberg and Patrick Heelan. To explain something for Heisenberg is to describe what can be intersubjectively observed and conceptualized in an adequate language. However, this needs to be qualified, as not any adequate account will do. While Heisenberg thinks that Kant is right to think that a priori concepts are the conditions which make science, and thus explanation, possible, he also believes pure a priori concepts have a limited range of applicability. Neils Bohr shared this belief with Heisenberg, but thinks human thought can go no further. However, Heisenberg never gave up on the idea that we could create new concepts that act as a priori grounds for quantum entities. To go beyond Heisenberg, I believe that we should look to Husserl’s account of Evidenz and the material a priori to help us think about a phenomenological account of explanation.
