 Wyclif maintained that such an approach to philosophical questions was misleading and deleterious. Many times in his works he expressed the deepest hostility to such a tendency. He thought that only on the basis of a close isomorphism between language and the world could the signifying power of terms and statements, the possibility of definitions, and finally the validity and universality of our knowledge be explained and ensured. So the nucleus of his metaphysics lies in his trust in the scheme object-label as the general interpretative key of every logico-epistemological problem. He firmly believed that language was an ordered collection of signs, each referring to one of the constitutive elements of reality, and that true (linguistic) propositions were like pictures of those elements’ inner structures or/and mutual relationships. From this point of view, universals are conceived of as the real essences common to many individual things, which are necessary conditions for our language to be significant. Wyclif thought that by associating common terms with such universal realities the fact could be accounted for that each common term can stand for many things at once and can label all of them in the same way.
