" We have for too long been taught that the sight of a man speaking to himself is a sign of eccentricity or madness; we are no longer at all habituated to our own voices, except in conversation or from within the safety of a shouting crowd. But a book suggests conversation: one person is speaking to another, and audible sound is, or should be, natural to that exchange. So I read aloud with myself as my audience, and gave voice to another’s words. "
