In "The Nature of Personal Reality" it is written
Dialogues of the Soul and Mortal Self in Time, The Speakers, and some Sumari poetry are being combined into a book that will be published soon by Prentice-Hall. I consider it a companion book to this one.
I know "Dialogues of the Soul and Mortal Self in Time" exists as a book, but does it contain the mentioned Speakers Manuscripts? I am curious, where they are found. The passage in NoPR makes it sound like The Speakers manuscript had been delivered and written.
Does anyone know?
