Abstract

A parallel argument to the doxastic voluntarist argument -- a general voluntarism argument -- can be constructed against both ethical and semantic internalism. In the ethical case, the parallel argument begins with the idea that if ethical internalism is true, that is, if we cannot help but be motivated to do the right thing internally, then it would appear that our being moved to do the right thing is involuntary in the same was as our beliefs are involuntary. If correct, this leaves the ethical internalist with a dilemma. Like the epistemologist faced with the doxastic voluntarism argument, she can either deny the plausible ought implies can principle in order to maintain that the idea that ethical obligations make sense, or she must rest content with the idea that ethical internalism has the status of a descriptive account of moral behavior rather than a prescriptive theory. But, the ethical internalist is engaged in giving an account of the nature of moral action, it is entirely unclear what differentiates moral behaviors from any other kind of internally motivated actions -- the normativity of morality is lost. If we believe that normativity is constitutive of morality, then ethical internalism fails even as a description of its nature. In the semantic case, if we cannot for instance simply decide that 'Glory' means the same as 'There's a nice knockdown argument for you', it is unclear how meaning could be determined internally and yet be normative at the same time. If ought implies can, and we cannot change the meaning of our expressions internally, then the normativity of meaning cannot come from the inside, it must come from without, but how could the normativity of linguistic behavior come from without given that it is an artefact? The semantic internalist therefore faces the same dilemma that both doxastic voluntarism and ethical internalism face.
