 Others claim that grounding is well-founded in the sense that any grounded fact is ultimately grounded by ungrounded facts (Dixon 2016; Rabin &amp; Rabern 2016). Note that this conception of the well-foundedness of grounding, in contrast to the one above, allows for infinitely descending grounding chains. How so? Following Bliss (2013) and Rabin and Rabern (2016), consider Euclidean space, which is comprised of points and regions that include those points. Suppose that regions are gunky in that every region has a region as a proper part. And suppose that the existence facts concerning regions are grounded by the existence facts concerning their sub-regions, the existence facts concerning sub-regions are grounded by the existence facts concerning their sub-sub-regions, and so on, ad infinitum. Hence, the fact that region R exists is a member of an infinitely descending grounding chain. But suppose that the existence facts concerning regions are also grounded by the existence facts concerning points. Suppose, moreover, that the existence facts concerning points lack grounds. Hence, while the fact that R exists is a member of an infinitely descending grounding chain, this fact nonetheless is grounded in facts that themselves lack grounds. The same applies to all the other facts that are links in the grounding chain in question.
