How can we reconcile Buddhism with expressive individualism (“be yourself”) and with natural science? When I had previously turned to Wilfrid Sellars for help on this question, I had compared Sellars’s view to two Buddhist metaphysical positions on ultimate truth, which are quite different from each other. One of these was Buddhaghosa’s view that ultimate truth is reductionist, and I no longer find that comparison helpful. But I also turned to Śāntideva’s view that the ultimate is normatively inert, with no good or bad involved. Śāntideva’s view rejects Buddhaghosa’s in some very important ways – and I think that philosophically his metaphysics is considerably more powerful.

That’s a big deal for me because, having come to my Buddhism in Thailand, I have generally viewed myself as a Theravādin like Buddhaghosa. I’ve been skeptical of the most famous piece of Śāntideva’s metaphysics, his ethical deconstruction of self and other in chapter VIII of the Bodhicaryāvatāra. I’m not convinced by his or any other argument for a universal impartial altruism – a key Mahāyāna doctrine. Yet I do now find myself moving closer to a Mahāyāna or at least Madhyamaka view, because of a different aspect of Śāntideva’s metaphysics: the metaphysics of emptiness in chapter IX, which I think are considerably deeper.
