In a few short texts, assigned to a mature period following a famous ‘conversion’ to Mahayana Buddhism, Vasubandhu argues that reality consists of ‘impressions-only’ (Siderits 2007), or ‘only appearance’ (Gold 2015). This prima faciemetaphysical idealism came to be known, famously and more simply, as the ‘Cittamatra’ view, which means ‘mind-only’.
Taking ‘external world’ to mean a world in space and time that is putatively independent of the mind, Vasubandhu argues that this conception is a delusion, one that imposes a crude conceptual grid on the field of experience. As a critic of ‘naïve realism’, Vasubandhu sees unchecked mental projections as imposing a spatiotemporal structure on experience which, once purged of this, can also be liberated from other forms of ignorance. In his Twenty-Verse Treatise, Vasubandhu considers various objections to this irrealist account of belief in an external world, responding by invoking e.g. analogies of dream-experience (and other intriguing anticipations of modern philosophy).
