Despite the affinity of monism and monotheism—and despite monism’s recent philosophical renaissance—few have defended the conjunction of the two claims, of what we might call ‘theistic monism’. I argue, first, that monism and monotheism are consistent, and second, that each one provides good reasons to accept the other one. Monotheists, qua monotheists, have good reason to be monists; and monists, qua monists, have good reason to be monotheists. There should be much greater overlap between the monist camp and the monotheist camp than there is at present.
