Frederick Copleston on the limits of human language and metaphysics

“Language is primarily designed to refer to the objects of our sense-experience, and is very often found inadequate for the precise expression of metaphysical truths. Thus we speak, and cannot well help speaking, of “God foreseeing,” a phrase that, as it stands, implies that God is in time, whereas we know that God is not in time but is eternal. We cannot, however, speak adequately of the eternity of God, since we have no experience of eternity ourselves, and our language is not designed to express such matters. We are human beings and have to use human language — we can use no other: and this fact should make us cautious in attaching too much weight to the mere language or phrases used by Plato in dealing with abstruse, metaphysical points.”
