 In this way, Wyclif eliminates from the description of the relatives of reason any reference to our mind, and utilizes objective criteria only, based on the framework of reality itself. In fact he maintains that there are three kinds of relations of reason, each one characterized by the occurrence of at least one of these negative conditions: (1) one of the two extremes of the relation is not a substance with its foundation; (2) both the extremes of the relation are not substances; (3) there is no foundation for the relation, or it is not an absolute accident – that is, a quantity, or a quality (ibidem). The strategy which supports this choice is evident: Wyclif attempts to substitute references to mental activity by references to external reality. In other words, he seeks to reduce epistemology to ontology, in accordance with his realist program.
