 Though they share a common denial that anything has intrinsic nature, Madhyamaka philosophers differ in their views about various other philosophical issues; indeed, some within this tradition hold that the goal of practice is to have no views at all. Within the overall framework of Madhyamaka, Tibetan scholars generally classify Śāntideva as belonging to the Middle Way Reductio School (Skt. Prāsaṅgika-madhyamaka, Tib. dbu ma thal ‘gyur pa) of Buddhapālita and Candrakīrti. This form of Madhyamaka is opposed to the Middle Way Autonomous School (Skt. Svātantrika-madhyamaka, Tib. dbu ma rang rgyud pa). Some modern writers have viewed this doxographical identification with skepticism, noting that Śāntideva takes no explicit position on the issues of argumentative and logical methodology that, they believe, were the core questions at issue between Candrakīrti and Bhāvaviveka. Indeed, these Indian masters would not have used the terms Prāsaṅgika and Svātantrika to describe themselves, and some scholars have questioned the extent to which Tibetan doxographical categories can helpfully illuminate Indian philosophical discussions, as opposed to oversimplifying or distorting them.
