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.
