Are there any references in Corpus Aristotelicum to suggest whether Aristotle was aware of Buddhist teachings or Eastern philosophy? Aristotle travelled to Asia Minor at one stage of life, left a voluminious treatise, yet it is interesting there is no shred of evidence alluding to Buddha, Confucius, Lao Tsu or other eastern teachings for a man of such stature. (Research yielded an interesting note of cornocupia of 'facts' whose source is not verified to Aristotle, but should it be then it further begs the question of the lack of reference to Buddha.) Although Gier has drawn interesting parallels between Aristotle and Buddha in Experiments in Truth, I am interested to know if there has been any reference to this particular area.
The short version is: there is considerable evidence of the communication of philosophical ideas between the classical Greek and Indian worlds, in both directions; in terms of Buddhism, this can be most easily seen with Epicureanism, and the connections between Pyrrhonism and Madhyamaka Buddhism.
However, there's no direct evidence that applies to Aristotle. He may have known of Buddhist teachings, or he may not have.
