From modal collapse to moral collapse

Abstract

Abstract I aim in this article to contribute two points to the ongoing discussion regarding strong DDS and modal collapse. First, I will examine a recent version of the modal collapse objection formulated by R. T. Mullins, demonstrating that one can modify the argument to survive its most forceful rejoinder. Having established the cogency of Mullins's modal collapse argument, I next aim to heighten the severity of the conclusion. In particular, I demonstrate that the success of the modal collapse argument entails a moral collapse wherein well-established principles of ethical reasoning fail. Finally, I examine a recent attempt by Katherine Rogers to undercut some of the unwelcomed results of a modal collapse via an appeal to the theistic multiverse. I conclude that this manoeuvre proves ineffective against the moral collapse objection.
