According to Tegmark "there is only mathematics; that is all that exists". Suppose he is right. Then moral truths, if there are any, are (along with all other truths) mathematical truths. Unless you presuppose that moral truths cannot be mathematical truths then you have not ruled out moral truths when you say that so-and-so is not contingent on anything except mathematics and such-and-such. For my part I fail to see why moral truths could not be mathematical truths.
