Two Vasubandhus
Erich Frauwallner, a mid-twentieth 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 Abhidharmakośa 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." There is no scholarly consensus on this question at present.
