Editing Law of noncontradiction (section)

=== Avicenna ===
[[Avicenna]]'s [[The Book of Healing#Philosophy|commentary]] on the ''[[Metaphysics (Aristotle)|Metaphysics]]'' illustrates the common view that the law of non-contradiction "and their like are among the things that do not require our elaboration." Avicenna's words for "the obdurate" are quite facetious: "he must be subjected to the conflagration of fire, since 'fire' and 'not fire' are one. Pain must be inflicted on him through beating, since 'pain' and 'no pain' are one. And he must be denied food and drink, since eating and drinking and the abstention from both are one [and the same]."<ref>Avicenna, ''[[Metaphysics]]'', I.8 53.13–15 (sect. 12 [p. 43] in ed. Michael Marmura); commenting on Aristotle, ''Topics'' I.11.105a4–5. The editorial addition (brackets) is present in Marmura's translation.</ref>
