Listening to my regular favourites - Mozart Beethoven Brahms and so on - I always feel quite misguidedly that nothing can be too bad if such beauty and brilliance exists in the world.
It is a sobering thought that when Mozart was my age he had been dead for two years.
Everything deep is also simple and can be reproduced simply as long as its reference to the whole truth is maintained. But what matters is not what is witty but what is true.
