Kamal al-Din al-Nabhani

Kamal al-Din al-Nabhani (Full transliterated name: Sheikh Muhammad Kamal al-Din ibn Muhammad Taqi al-Din ibn Ibrahim bin Mustafah bin Yusuf bin Ismail bin Yusuf al-Nabhani; Arabic:الشيخ محمد كمال الدين بن محمد تقي الدين بن إبراهيم بن مصطفى بن إسماعيل بن يوسف النبهاني; born on January 3, 1929 in Beirut, Lebanon and died December 31, 2006) was one of the founders of the Islamist political party Hizb ut-Tahrir and was a son of Sheikh Taqi al-Din al-Nabhani, born in Ijzim, Haifa, and died in Beirut, Lebanon in 1977. He died aged 77 in 2006.

Nabhani in his books 'Thought' and 'System of Islam 2' after his father Taqiuddin al-Nabhani placed heavy emphasis on discussing modes and models of the psychology behind human thought, and concepts. He defined the thought process, and how it reaches the status of conviction or concepts. He discussed the internal working of thoughts, convictions, and concepts in shaping the Nafs or emotions and sentiments. Delving into the internal workings of how people reach conclusions & the psychology behind the process derives itself from Taqiuddin al-Nabhani's roots in non-Ascetic legalistic Sufism from his first teacher and maternal grandfather Ismail al-Nabhani.

Al-Nabhani's definitions of thought have been used in the study of Computer Science, Artificial Intelligence, and information processing research discussed in the Addison-Wesley published book "Conceptual Structures: Information Processing in Mind and Machine (Systems Programming Series)" and used in London South Bank University's information systems department.

After many philosophical discussions on the nature of thoughts and emotions, Nabhani concludes that the only way to bring about change is via discussion, refutation, and revival of the relevant thoughts and emotions. It is from this philosophical basis that he argued that force does not work to change peoples' ideas. He also argued that a decline in the Muslims' thought, emotions and concepts led to their decline & the eventual destruction of the Khilafah. He believed the first major step towards decline in the Muslims was confusion about, and dealing with new foreign ideas, mainly Greek, Persian & eastern philosophy.
