    The fact that the Axiom of Choice implies Excluded Middle seems at first sight to be at variance with the fact that the former is often taken as a valid principle in systems of constructive mathematics governed by intuitionistic logic, e.g. Bishop’s Constructive Analysis[16] and Martin-Löf’s Constructive Type Theory[17], in which Excluded Middle is not affirmed. In Bishop’s words, “A choice function exists in constructive mathematics because a choice is implied by the very meaning of existe
