The text discusses the issue of the relation between choice (electio) and justice (iustitia) in Joachim of Fiore (1135-1202). We defend the thesis that, although the abbot has present the Augustinian solution in which divine grace is the reason of choice and justice that of rejection, he does not assume integrally Augustine’s legacy. In another way, understands that choice springs form a negative attitude: the humility of the chosen. And rejection, otherwise, has a baser reason: pride. Its general scheme isn’t supported by an understanding of distributive justice by worthiness, but on the benefit of the weaker, smaller, the abject.
