There is a moral in the ‘Nominalist and Realist’ that will prove all sums. It runs something like this: No matter how sincere and confidential men are in trying to know or assuming that they do know each other’s mood and habits of thought, the net result leaves a feeling that all is left unsaid; for the reason of their incapacity to know each other, though they use the same words. They go on from one explanation to another but things seem to stand about as they did in the beginning ‘because of that vicious assumption.’ But we would rather believe that music is beyond any analogy to word language and that the time is coming, but not in our lifetime, when it will develop possibilities unconceivable now, — a language, so transcendent, that its heights and depths will be common to all mankind.
Charles Ives, in Essays Before a Sonata (1920).
