Qisṭās al-afkār

A systematic handbook of logic built on the division into conceptions and assents, which cites al-Fārābī, Ibn Sīnā, al-Ghazālī, Fakhr al-Dīn al-Rāzī, Abū al-Barakāt and al-Abharī and does not hesitate to criticise them. Its distinctive feature is a closing section on the etiquette of debate (ādāb al-baḥth) and on fallacies, meant to replace the Topics and Sophistical Refutations; it largely succeeded, and the new discipline of ādāb al-baḥth was often copied with logic manuals. Al-Samarqandī wrote his own commentary on it (Sharḥ al-Qisṭās). It marks the point where debate theory entered the logic curriculum.
