The acedia, is received by the Patristic, with special development in the Egyptian desert with Evagrio Pontic. The development of this logismoi and sin will revolve around its relationship with sadness and laziness, as well as a discursive development in the monastic and secular space, projected throughout the Middle Ages. The objective is to show the transmutation of the term and the conceptualization of acedia throughout the medieval period in the Latin west, with special attention to the writings of Evagrio Ponticus and Saint Thomas Aquinas.
