The Concept of Acquired Knowledge (‘ilm al-husulī); Its Reformation in the Discourse of Muslim Scholars

This paper examines the concept of acquired knowledge (‘ilm al-husulī) in the discourse of Muslim scholars in relation to the reforms made by many Muslim scholars and thinkers such as al-Shafi‘ī (d.204/820), al-Ghazalī (d. 505/1111) and al-Dihlawī (d.1176/1762). Al-Shafi‘ī contributed much to this field with his classification of knowledge into two categories, ‘ilm al-‘ammah and ‘ilm al-khassah. Al-Ghazalī, who developed ‘ilm al-mu‘kashafah and al-mu amalah, suggested a method of revivification (ihya) in order to integrate the sciences of acquired knowledge. Al-Dihlawī developed and classified knowledge into ‘ilm al-hudurī and al-husulī, and suggested the concept of tatbīq in reforming acquired knowledge. Their discussions on the reformation of acquired knowledge have paved the way for modern scholars to derive concepts for the integration of human knowledge.
