 We could write an entire essay on questions raised in our summary in the previous paragraph, but Hamkins has already done this in Hamkins 2012. Our aim here is to summarize the tentative axioms that Hamkins presents for the multiverse conception. This is not really a formal set of axioms, but it does have some of the qualities of an axiomatization of an alternative set theory. We note that the list of axioms presented here unavoidably presupposes more knowledge of advanced set theory than other parts of this article.
