Spirit. "What are they?"

Myself. "Men, or, as you would say, spirits, like us in a few respects, but utterly different in most."

Spirit. "Have you ever seen them?"

Myself. "No."

Spirit. "Or met anyone who has?"

Myself. "No."

Spirit. "Then this account of them tallies with nothing in your experience."

Myself. "No, but they exist all right. There's no doubt of that."

Spirit. "I question it. In any case, I could not accept your word as evidence, seeing that you have neither seen them yourself nor met with anyone who has."

And so on, you know (the Researcher muttered, flicking over the pages of his note-book).
