Does one ever see any ghost that is not oneself?

The more enlightened our houses are, the more their walls ooze ghosts.

Behind every man now alive stand thirty ghosts, for that is the ratio by which the dead outnumber the living.

You want to know whether I believe in ghosts? Of course I do not believe in them. If you had known as many of them as I have, you would not believe in them either.

I'm inclined to think we are all ghosts-every one of us. It's not just what we inherit from our mothers and fathers that haunts us. Its all kinds of old defunct theories, all sorts of old defunct beliefs, and things like that.

Ghost, n. The outward and visible sign of an inward fear.
