Reply to Horta: Spectrum Arguments, the “Unhelpfulness” of Rejecting Transitivity, and Implications for Moral Realism

Abstract

This article responds to Oscar Horta’s article “In Defense of the InternalAspects View: Person-Affecting Reasons, Spectrum Arguments andInconsistent Intuitions”. I begin by noting various points of agreementwith Horta. I agree that the “better than relation” is asymmetric, and pointout that this will be so on an Essentially Comparative View as well as on anInternal Aspects View. I also agree that there are various possible Person-Affecting Principles, other than the one my book focuses on, that peoplemight find plausible, and that in some circumstances, at least, these mighthave deontological, rather than axiological significance. In particular,I grant that Horta’s Actuality-Dependent Person-Affecting Principle, hisTime-Dependent Person-Affecting Principle, and his Identity-DependentPerson-Affecting Principle, might each be relevant to what we ought todo, without necessarily being relevant to which of two outcomes is better.But I reject Horta’s claim that essentially comparative principles don’tapply in Spectrum Arguments. I also argue against Horta’s view that thetwo Standard Views that underlie our intuitions in Spectrum Argumentsare contradictory. I question Horta’s (seeming) position that there isno point in rejecting the transitivity of the “better than” relation on thebasis of Spectrum Arguments, on the grounds that doing so won’t solvethe predicament that Spectrum Arguments pose. Finally, I conclude mypaper by challenging Horta’s interesting contention that my views aboutnontransitivity support an anti-realist metaethics, and are incompatiblewith the sort of realist approach to metaethics that I favor.
