Well, Edgar, if this demon has the same wisdom and foresight our benevolent spirits possess, and he believes your story will be relevant to men in a time of billionaires, you should not have scoffed at me when I said I believe your poetry will echo throughout the ages, long after you and I are gone.

Clearly, I am not the only one who believes as such.
