  This assumption may be questioned. Our knowledge of the Buddha’s teachings comes by way of texts that were not written down until several centuries after his death, are in languages (Pāli, and Chinese translations of Sanskrit) other than the one he is likely to have spoken, and disagree in important respects. The first difficulty may not be as serious as it seems, given that the Buddha’s discourses were probably rehearsed shortly after his death and preserved through oral transmission until the time they were committed to writing. And the second need not be insuperable either. But the third is troubling, in that it suggests textual transmission involved processes of insertion and deletion in aid of one side or another in sectarian disputes. Our ancient sources attest to this: one will encounter a dispute among Buddhist thinkers where one side cites some utterance of the Buddha in support of their position, only to have the other side respond that the text from which the quotation is taken is not universally recognized as authoritatively the word of the Buddha. This suggests that our record of the Buddha’s teaching may be colored by the philosophical elaboration of those teachings propounded by later thinkers in the Buddhist tradition.
