This concluding chapter explains that for all of their eclecticism, and for all their seeming paradoxes, the polymaths of Islam were united by a common madrasa education, mastery of a canon of texts, and shared regional networks. Their curriculum went far beyond the grammar and logic emphasized in the madrasa. Even mastering substantive Islamic law from medieval Arabic texts was necessary, but not sufficient, to distinguish a high Persianate intellectual from his many, many competitors. Most of the ulama — especially those who rose to the top — studied a plethora of collateral disciplines: poetry, mysticism, astronomy, calligraphy, medicine, trade, and more. Secondary scholarship often pairs these forms of knowledge with discrete communities, differentiating scholars, poets, sufis, and physicians into distinct social groups, with the sufi-ulama dichotomy especially pronounced. However, these were not separate groups with separate corporate identities. Rather, they were discrete social roles performed by a single social group. Their integrated knowledge base allowed them to mix and match social functions with impunity.
