It stands poised between the author and the reader, so clearly something is required from both in order for the circuit to be completed. I simply do not understand why one should have to be the master, as though one were to ask whether the ability to speak or the ability to understand were more important in conversation

Should we allow more changes in the statistics as given above (with regards to the titular 'Book or the Reader' issue?
