 Tsongkhapa does not accept svātantra (“autonomous”) reasoning (the fourth point). He asserts that it is enough, when proving that any given subject is empty of intrinsic existence, to lead the interlocutor, through reasoning, to the unwelcome consequences (prasaṅga) in their own untenable position; it is not necessary to demonstrate the thesis based on reasoning that presupposes any sort of intrinsic (=autonomous) existence. This gives Tsongkhapa's philosophy its name *Prāsaṅgika-madhyamaka, i.e., a philosophy of a middle way (between nihilism and eternalism) arrived at through demonstrating the unwelcome consequences (in any given position that presupposes intrinsic existence).
