Abstract

Some Christian philosophers, notably Tertullian, have gloried in this absurdity, finding in its very irrationality a sign of the dogma's truth. But most Christian philosophers, following Augustine, have tried to find some reconciliation between reason and revelation. The history of medieval philosophy is the history of the attempt to make the revealed truths rationally intelligible. The attempt was a failure. As we proceed chronologically from Anselm of Canterbury to Abelard, Thomas Aquinas, Duns Scotus, and William of Occam, we find the domain of intelligibility relentlessly contracting as standards of logical rigor were raised. Anselm could prove all the dogmas of the Church. Abelard could prove the Trinity but not the Incarnation. Aquinas could prove that God is our beatitude but not that he is a Trinity. Scotus could prove that God exists, but not that he is our beatitude. William of Occam could not prove even that God exists, for without revelation we know only the immediately obvious and what can be inferred from it, the empirical world. As the rational defense of Christian doctrine collapsed, the domain of rational philosophy grew smaller and smaller, leaving dogmatic theology the sole defender of metaphysical truth. The alternatives seem to be to refute William of Occam's positivistic analysis, to accept revelation blindly, or to get along without metaphysics. None of these is easy.
