Grounds, Roots and Abysses

The aim of this study is to address the “Grounding Grounding Problem,” that is, the question as to what, if anything, grounds facts about grounding. I aim to show that, if a seemingly plausible principle of modal recombination between fundamental facts and the principle customarily called “Entailment” are assumed, it is possible to prove not only that grounding facts featuring fundamental, contingent grounds are derivative but also that either they are (at least) partially grounded in the grounds they feature or they are “abysses” (i.e., derivative facts without fundamental grounds and lying at the top of an infinitely descending chain of ground).
