 But it might be suggested that these problems for Mellor’s claim can be handled by introducing a ceteris paribus clause in much the same fashion as, as we have seen in  section 1.5,  some philosophers do with respect to conventional dispositions. The suggestion is that the stimulus condition of triangularity is not simply \(x\)’s corners being correctly counted but \(x\)’s corners being correctly counted under certain standard conditions. Although ‘\(x\) is triangular’ may not entail Mellor’s conditional as it stands, it does entail that if \(x\)’s corners were correctly counted under certain standard conditions, it would give the result of three, where the standard conditions are understood to rule out cases where reverse-finks or maskers operate or quirky laws of nature obtain. Notwithstanding this defence of Mellor’s claim, however, Choi argues that it is still hopeless, to which we will turn below.
