What is it about?

The ancient Arab logicians knew and developed a form of deduction of which neither Aristotle nor the Stoics had an idea about i.e. the theory of syllogisms with conditional and disjunctive connectives that they subsumed under five categories and had its completion in Muḥammad Ibn Yusūf al-Senūsī's work i.e. in his explanation of Kitāb al-Muḫtaşar fī al-Manṭiq of al-Imām Muḥammad Ibn Arfa (1316 - 1401)
