Two Vasubandhus theory

Erich Frauwallner, a mid-20th-century Buddhologist, sought to distinguish two Vasubandhus, one the Yogācārin and the other a Sautrāntika, but this view has largely fallen from favour in part on the basis of the anonymous Abhidharma-dīpa, a critique of the Abhidharmakośakārikā which clearly identifies Vasubandhu as the sole author of both groups of writings. According to Dan Lusthaus, "Since the progression and development of his thought... is so strikingly evident in these works, and the similarity of vocabulary and style of argument so apparent across the texts, the theory of Two Vasubandhus has little merit." Scholarly consensus on this question has generally moved away from Frauwallner's "two-authors" position.
