In this paper, I criticize the pairing of irreducible thickness with the traditional view of evaluation which says evaluation is a matter of encoding good or bad in some way. To do this, I first explicate the determination view, which holds that irreducibly thick concepts are to thin concepts as determinates are to determinables. I then show that, even if the determination view did establish irreducible thickness, it would not have proven that the evaluative is well understood as being an (...) instance of the determination relation; in order to do that, the determination view needs to show how the evaluative fit a general analysis of the determination relation. However, when the determination view attempts to fill in the analysis, we get implausible results—so implausible, I claim, that we should see the results as a reductio to the view. To generalize the criticism to any view like the determination view, I show that the same results ensue when we model the evaluative on mereology. Finally, I diagnose the general failure by claiming that the evaluative domain, as conceived by the defender of irreducible thickness, just does not have the structure to secure the tight connection between thick and thin concepts while also carving up our conceptual economy in a plausible way.

I address a family of objections I label the _So What?_ objection to robust non-naturalist realism (or, just non-naturalism). This objection concludes that non-naturalism fails to identify the _moral properties_ in virtue of failing to explain why non-natural properties would have all the features we expect _moral properties_ to have and can be extended to provide the conclusion that the non-naturalist is therefore immoral. I argue that _So What?_ is question-begging because it disallows non-naturalists their central theoretical claim: there are (...) ethical properties iff they are fundamental properties (and, in virtue of that, non-natural). I then diagnose the error anti-non-naturalists make explicitly: those who object to non-naturalism along the lines of _So What?_ either fail to understand precisely what the theory claims or fail to understand non-naturalist motivations for going in for that theory.

In this review, I provide a brief overview of the book and then make a brief statement about where I think the debate stands with respect to error theoretic moral semantics.

I review T. Ryan Byerly's treatment of the possible virtue of others-centeredness.
