Abstract

In Sect. 1 an argument for Yogācāra Buddhist Idealism, here understood as the view that everything in the universe is of the nature of consciousness / cognition, is laid out. The prior history of the argument is also recounted. In Sect. 2 the role played in this argument by light as an analogy for cognition is analyzed. Four separate aspects of the light analogy are discerned. In Sect. 3, I argue that although light is in some ways a helpful analogy for the Buddhist Idealist, in other ways it is thoroughly inappropriate. At the end of the article I ask whether the lack of fit between light and cognition is unavoidable, or whether the Buddhist Idealists could have chosen a better analogy
