chunk: Ibn Tufail drew the name of the tale and most of its characters from an earlier work by Ibn Sina (Avicenna), but the plot was very different, and the book was a new and innovative work in its own right. Avicenna's story was essentially a thought experiment about the active intellect, personified by an elderly sage, instructing the narrator, who represents the human rational soul, about the nature of the universe.
  The plot of Ibn Tufail's more famous Arabic novel was inspired by Avicennism, Kalam and Sufism, and was also intended as a thought experiment. Ibn Tufail's novel tells the story of an autodidactic feral child, raised by a gazelle and living alone on a desert island in the Indian Ocean. After his gazelle mother passes away when he is still a child, he dissects her body and performs an autopsy in order to find out what happened to her. The discovery that her death was due to a loss of innate heat sets him "on a road of scientific inquiry" and self-discovery.
