  Premise (11) is opposed by moral coherentists (e.g. Brink 1989, Sayre-McCord 1996,  Sinnott-Armstrong 2006, Chapter 10, pp. 220–251). Recent coherentists emphasize that they do not infer a belief from itself in a linear way. Instead, a moral belief is supposed to be justified because it coheres in some way with a body of beliefs that is coherent in some way. Still, moral skeptics deny that coherence is enough to make a moral belief justified. One reason is that the internal coherence of a set of beliefs is not evidence of any relation to anything outside the beliefs. Another reason is that every belief — no matter how ridiculous — can cohere with some body of beliefs that is internally coherent. Because so many incompatible systems seem coherent, moral skeptics deny that coherence alone is sufficient to make beliefs justified.
