Can we form true propositions about God? Some say no – but one would have to know a great deal about God in order to be certain that one could not know anything else about Him. At every stage of his writing, St. Thomas has taught that what we can say about God is limited. In this life we do not see His very essence, and the mere backwash of His glory would overwhelm us. However, whether our little speeches are inadequate is not the question: rather we should ask whether their inadequacy makes them false. Can we say anything positive about God? Throughout this book St. Thomas has been making affirmative statements about Him. But even if we can, then what kinds can we make, and in what sense should we take them? We might even ask what it is about the reality of God that makes talking about His reality so difficult – and yet so important.
