The denouement of Part 1 might seem disappointing. Greatness of soul, that larger-than-life ancient virtue, enters the Islamic world only to fade away. Yet there was another concept belonging to the same broad family that led a more flourishing life in the Islamic world. This virtue, designated as ‘greatness of spirit’ (ʿiẓam al-himma), appears in philosophical treatises but also in other genres, including mirrors for princes and works of literature (adab). Unlike the first concept, which thematized the right attitude to the self and its merits, this second concept thematizes right desire or aspiration, and some of its architects parse it as a foundational virtue of aspiration to virtue. Part 2 first documents its development in works of a philosophical character, notably Yaḥyā ibn ʿAdī’s and al-Rāghib al-Iṣfahānī’s, before considering its presentation in mirrors for princes. There are interesting comparisons to be drawn between the way the virtue is articulated across different genres, and also suggestive comparisons with approaches familiar from broader philosophical history. These observations invite a question about the origins of the virtue. While the Greek influence cannot be excluded, a stronger argument can be made for the influence of the Persian cultural tradition and, more compellingly, pre-Islamic Arab culture. ‘Greatness of spirit’ was an epithet applied to the Arab hero of pre-Islamic times. This heroic ideal is reconfigured in the Islamic era in important ways. This genealogy allows us to place on new footing the question about the relationship of the ‘virtues of greatness’ to Islamic religious morality.
