The first principles behind the developmental idea are linear time, interiority and staged structure. ‘Development’ is one particular historical way of conceptualizing the primary principle of change; in it, human time is an attempt at successful ‘recapitulation’ (a term that would reappear with modern developmental psychology’s founder, G. Stanley Hall) of Adam’s initial failure. In monotheism, time constructs interiority as permanence, ‘the mind’, in contrast with the temporary visitations of pagan or shamanic religion. Medieval psychology saw a proliferation of its ‘faculties’ (memory, imagination, judgement) and ‘operations’ (abstraction, attention, consciousness, logical reasoning, information-processing), which penetrated both the monastic and the humanist idea of the individual. Augustine’s ‘six ages’ of man gave the lifespan a fixed structure. Following the Reformation, change in the elect minority was seen either as instantaneous or as a stadial sequence: Jansenists and Calvinists on the one hand, Jesuits and Arminians on the other, disputed the function of human agency in relation to divine determinism.

Chapter 3 considers the development of scholastic exegesis outside the universities, focusing on the Yorkshire hermit-mystic Richard Rolle (d. 1349). With only a limited university education, Rolle turned to scholastic commentary, especially on the Psalms, to create material for devotional reading, and he wove authoritative opinions quarried from major scholastic sources together with glosses that read different psalms as describing his distinctive mystical experiences. Rolle wrote two Psalter commentaries reflecting these priorities, first in Latin and then in English, with the later work representing a substantial revision of the earlier one. After assessing the development of his interpretive program across these texts, the influence of Rolle’s vernacular commentary is then charted, focusing on its revision in the last quarter of the century and the various works that imitate its form. Finally, by considering the citations of Rolle’s works by Oxford theologian Richard Ullerston, this chapter reveals the success of Rolle’s hermeneutic project, arguing that the hermit returned to the university with an authority that was at once scholastic and devotional.
