In early 12th-century al-Andalus, the Arabian philosopher, Ibn Tufail (Abubacer), wrote discussions on materialism in his philosophical novel, Hayy ibn Yaqdhan (Philosophus Autodidactus), while vaguely foreshadowing the idea of a historical materialism.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): When did Ibn Tufail die?
unanswerable
