 Debate concerning the nature of mataphysical explanation and the concept of grounding is quite prolific and ongoing. (For a detailed discussion see the SEP entry on Grounding.) What one must keep in mind when it comes to Bradleyean problems and grounding is that the former debate is itself quite varied and without a consensus on either the nature of the problem or the desiderata for the satisfactory solution. Thus, caution should be advised when importing conclusions from one contentious problem into the area of another even more abstract and contentious one.
