Abstract
Mark Siderits has been one of the sharpest, clearest philosophers working on Buddhism in the last several decades. His work has also been strikingly wide-ranging. In this chapter, we will focus on two themes in his work that we find particularly interesting. First, Siderits makes a strong case that Abhidharma Buddhists promote mereological nihilism – the view that only simple entities are ultimately real, and aggregates (like a chariot or a heap) are at best useful fictions. Mereological nihilism grounds an argument against the existence of selves, which of course, is central to the tradition. But Siderits draws out a further, bracing conclusion from mereological nihilism – that consciousness isn’t ultimately real. We think this conclusion so antithetical to other commitments of Buddhism that it provides reason to doubt whether Buddhists should sustain the commitment to mereological nihilism. There is another important argument for the no-self view, however, Vasubandhu’s causal-efficacy argument; on this argument, real things must enter in cause-and-effect relations, and when we turn to cause-and-effect, there is no place where the self plays a necessary role. This argument informs our exploration of the second theme from Siderits – his defense of the “personalist” view that person (unlike self) is a useful fiction. We challenge this claim, first by noting that Vasubandhu himself uses the causal-efficacy argument against both selves and persons, and second by arguing that selves and persons are also on a par when it comes to whether they are useful fictions.
