 In response it has been suggested that “ought” in (ME1) is replaced by a “may”. This allows the normativist to retain the biconditional and yet avoid the troubles caused by the principle that ought implies can: That an action is correct implies only that one may do it, not that one is obligated to do it, and there is no principle that ought implies can. If “green” is true of green objects only then \(S\) may apply “green” to an object if and only if it is green, and this is not in conflict with the fact that the subject is not able to apply “green” to every green object there is (Whiting 2009: 544 and 2010: 216; Peregrin 2012: 88).
