Upon his unplanned trip to Egypt, Avempace wrote Risālat al-wadāʿ (Letter of Bidding Farewell) and Risālat al-ittiṣāl al-ʿaql bi al-insān (Letter on the Union of the Intellect with Human Beings) that were dedicated to Ibn al-Imām. His famous works included Tadbīr al-mutawaḥḥid (Management of the Solitary), the Kitāb al-nafs (Book on the Soul), and the Risāla fī l-Ghāya al-insāniyya (Treatise on the Objective of Human Beings). The reflections of his famous accomplishments show how these were written near the end of his life. He was inspired based on Aristotelian line. In Avempace's philosophy, it contains two key pillars, solitude and conjunction. Solitude represents the isolation philosopher commonly seeks in order to protect himself from the corruption of society and conjunction refers to the philosopher's quest for the lowest celestial intelligence. It is required for the human soul's development.
