 The main part of his argument settled, Vasubandhu entertains another set of counterarguments, which are the charges of solipsism and moral nihilism: How, the internal objector asks, can beings interact with one another? What is the karmic benefit of helping or harming, when we are all merely apparent beings? Vasubandhu’s direct, candid response to these challenges may be viewed as a failure of imagination, or a surprising willingness to bite the bullet of anti-realism. Mental streams, he says, interact in essentially the same way as we imagine physical objects to interact. Minds affect minds directly. When you speak to me, and I hear you, we ordinarily think that your mind causes your mouth to produce sounds that my ears pick up and transform into mental events in my mind. Vasubandhu takes Occam’s razor to this account and says that—given that we have no sensible account of physicality, let alone mental causation of a physical event and physical causation of a mental event—it makes more sense if we eliminate everything but the evident cause and the result: Your mind and mine.
