Bhavaviveka's arguments for emptiness

In defending the teaching of emptiness, Bhavaviveka offers some very strange arguments, which initially may appear so weak that we may be hard pressed to understand how anyone could endorse them. To make sense of these passages, it is helpful to compare them to an argument found in the writings of the Naiyayika Uddyotakara. These arguments have a certain formal feature which makes them count as valid from the point of view of the rules and norms of some forms of Indian logic. Once we understand the logical structure of the arguments offered by Uddyotakara and Bhavaviveka, we will not only have a better grasp on their philosophical views, but we will also be in a better position to understand how and why those views were rejected by later figures in the Indian tradition, such as Dharmakrti and Santarakita.
