What did Ramakantha contribute to the Buddhist-Brahmanical atman debate?

In attempting to refute the Buddhist doctrine of no-Self, Ramakantha absorbed many features of Buddhism. For example, he sided with Buddhism against Nyaya and Vaisesika in denying the existence of property-possessors (dharmins) over and above properties (dharmas), and in denying a Self as something that exists over and above cognition. For him the Self simply is cognition (jnana, prakasa, samvit) and so he has to prove that cognition is constant and unchanging. I will present those arguments of Ramakantha's that strike me as his strongest and most original. I will spend at least the first 10 minutes of the talk introducing, and giving an overview of, the Buddhist-Brahmanical atman debate.
