John Hick on Language and PerceptionAn Interpretation of Religion, (New Haven: Yale University Press, 1989), p. 350.
It is within the phenomenal or experienceable realm that language has developed and it is to this that it literally applies. Indeed the system of concepts embodied in human language contributed reciprocally to the formation of the humanly perceived world. It is as much constructed as given. But our language can have no purchase on a postulated noumenal reality which is not even partly formed by human concepts. This lies outside the scope of our cognitive capacities.
