 In response it has been suggested that the relevant normative consequences should not be understood in terms of obligations but, rather, in terms of commitments. This is the line taken by Alan Millar (2002 and 2004). Meaning statements, such as “‘Green’ means green”, Millar argues, are true in virtue of there being a rule-governed practice. If \(S\) uses “green” to mean green, therefore, she becomes a participant in this practice and incurs a commitment to use the term accordingly. To be properly committed, Millar suggests, \(S\) has to be disposed to adjust her use if she discovers that it is not in keeping with the meaning of the expression (as when \(S\) uses “arcane” to mean ancient). The commitment is not dependent on one’s desire to communicate, or on the intention to speak the truth, but merely on \(S\) participating in the practice of using “green” with a certain meaning. However, Millar stresses, it does not follow that she ought to use her expressions a certain way, since it does not follow that she ought to participate in the practice—there may be reasons to withdraw from the practice instead. Hence, one may participate in a practice without it following that one ought to “carry out the performances associated with one’s role” (Millar 2004:  173).[23]
