 Wycliffe's fundamental principle of the preexistence in thought of all reality involves the most serious obstacle to freedom of the will; the philosopher could assist himself only by the formula that the free will of man was something predetermined of God.He demanded strict dialectical training as the means of distinguishing the true from the false, and asserted that logic (or the syllogism) furthered the knowledge of catholic verities; ignorance of logic was the reason why men misunderstood Scripture, since men overlooked the connection, the distinction between idea and appearance.Wycliffe was not merely conscious of the distinction between theology and philosophy, but his sense of reality led him to pass by scholastic questions.
