Are counterfactuals with true antecedents and consequents trivially true? The principle of Conjunction Conditionalization →) is highly controversial. Many philosophers view it as an attractive feature of Lewis’s semantics for counterfactuals that it can easily be modified to avoid this principle. However, Walters and Williams beg to differ. They argue that Conjunction Conditionalization is an indispensable ingredient of any Lewisian semantics, since CC is entailed by standard Lewisian theorems and a plausible semantic claim about irrelevant semifactuals. If this is true, (...) the entire tradition of revisionist counterfactual semantics is misguided, and so are many philosophical theories in which counterfactuals play a role. We argue, in defense of the revisionist tradition, that Walters and Williams’ ‘plausible semantic claim’ is in fact anything but plausible. It turns out to entail semantic principles far more controversial than Conjunction Conditionalization. (shrink)

The conditional analysis of dispositions is widely rejected, mainly due to counterexamples in which dispositions are either “finkish” or “masked.” David Lewis proposed a reformed conditional analysis. This view avoids the problem of finkish dispositions, but it fails to solve the problem of masking. I will propose a reformulation of Lewis’ analysis, and I will argue that this reformulation can easily be modified so that it avoids the problem of masking. In the final section, I will address the challenge that (...) some dispositions appear to lack any stimulus condition, and I will briefly turn to the issue of reductionism. (shrink)

Many recently released Hollywood films feature superheroes like Superman, Ironman, the Hulk, Optimus Prime, and so on who possess amazing superpower and defeat supervillains with unassailable commitment to moral justice. Interestingly, different superheroes possess and exercise their superpower in very different fashions. What is more, this aspect of their difference is intimately related to an issue that is lately in intense debate among metaphysicians of powers and dispositions, the issue of the possibility of intrinsic interferers with dispositions. This paper will (...) argue that a strong case can be made against this possibility when we give due weight to the commonsensical understanding of superheroes and their superpower. Whilst other arguments have been raised against the possibility of intrinsic interferers with dispositions in the latest literature, this will present further difficulties for those who accept it.
