 In metaphysics, an account of explanation along something like these lines can (as noted by Roski 2019) be found already in the work of Bolzano. Recent attempts to adapt Kitcher’s model to suit metaphysical and not just scientific explanation include Kovacs (2020) and Baron &amp; Norton (2021) (see Bertrand 2019 for an account that, although not couched in terms of unification, has a lot in common with their views).
