 Choi (2005b) imagines a tricky triangle \(T_t\) which has the same intrinsic properties as an ordinary triangle except that it has an intrinsic property that would cause it to become rectangular if someone starts to count its corners. What if \(T_t\)’s corners were correctly counted under standard conditions? Given that standard conditions are generally thought to involve \(T_t\)’s extrinsic properties only, \(T_t\) would become rectangular in virtue of one of its own intrinsic properties; as a result, it would not elicit the result of three but the result of four. It is therefore not true that if \(T_t\rsquo\text{s}\) corners were correctly counted under standard conditions the result would be three. But it is intuitively evident that \(T_t\) is triangular. From this Choi concludes that ‘\(x\) is triangular’ does not even entail the ceteris paribus version of Mellor’s conditional.
