Taking this line of thought a little farther, the relativist might envision contents that are “sense-of-humor neutral” or “standard-of-taste neutral” or “epistemic-state neutral”, and circumstances of evaluation that include parameters for a sense of humor, a standard of taste or an epistemic state. This move would open up room for the truth value of a proposition to vary with these “subjective” factors in much the same way that it varies with the world of evaluation. (MacFarlane 2007: 6–7)
