 This concludes our discussion of metaphysical infinitism and fundamentality. This survey has focused on a subset of the growing literature on fundamentality with the aim of clarifying the various terminological issues surrounding the key notions and identifying some common themes. The ideas behind these notions are old as are the intuitions associated with the various arguments that we’ve seen for and against metaphysical foundationalism and infinitism. Recent helpful efforts to systematize some of the central ideas, especially that of well-foundedness, have made it much easier to have constructive discussions about the topic of fundamentality. It can be expected that further attempts to formulate arguments for and against different strengths of metaphysical foundationalism and infinitism will emerge in the near future.
