Leibniz’s argument stakes out one position on the grounding of necessary truths, but there are many rival views that do not invoke the existence of a necessary and eternal divine mind. A Platonist might respond by claiming that it hasn’t been shown that abstract entities do not have mind-independent existence, while Humeans would argue that necessary truths are all analytic, and that therefore only the structure of language or of our conceptual schemes is required to ground their truth.
