I am sitting before my subject and chatting with him; he is trying to describe to me what he 'sees' and what he 'hears'; it is not a question either of taking him at his word, or of reducing his experiences to mine, or coinciding with him, or sticking to my own point of view, but of making explicit my experience, and also his experience as it is conveyed to me in my own, and his hallucinatory belief and my real belief, and to understand one through the other.
