 The unique well-known work by the Spanish Arabo-Islamic philosopher Ibn Tufayl (d. 1185), the Living Son of the Watchful (Hayy ben Yaqzan), exerted a substantially limited ‘influence’ over Medieval Jewish philosophy. For example, Pines affirms that “there is no evidence to show that Maimonides was in any way influenced by Ibn Tufayl’s philosophic tale”, although this influence cannot be totally excluded (Moses Maimonides 1963, 1:cviii; see also Davidson 2005, 115–116).
