Jack maintains that the concept of ‘affectivity’, the emotional disposition of the human will towards either virtuous or sinful acts, stands at the crossroads of the thought and practices of two religious orders in the Middle Ages, the Cistercians and the Augustinian canons of the Abbey of Saint-Victor. Taking the underexplored genre of twelfth-century pre-Aristotelian, De anima (‘On the Soul’) treatises written by Cistercians and Victorine theologians as its source base, his project examines the significance of these texts in elaborating a psychology that stressed the harmonious interplay between sense perception and the emotional (affectus/affectio) and intellective faculties of the soul.
He is supervised by Professor Sophie Page (UCL) and Professor Charles Burnett (Warburg Institute), and his doctoral studies are supported by the Wolfson Foundation.
Jack received his BA honours in History from UCL in 2018. He then undertook an MA in Medieval and Renaissance Studies (2018) at UCL sponsored by a Baxendale scholarship.
His research interests include: affectivity and sensation; the history of emotions; the history of the senses; intellectual history; cultural history; medieval understandings of cosmology, morality, philosophy, science and theology.
