“...but the bible says that out of the overflow of the heart, the mouth speaks.”
You missed the point; Poe did not necessarily do or speak what has been attributed to him. All that was published by a man who hated him and did not have honesty as his goal.
Oh, I wasn’t aware that people ghost wrote for Poe. If they did, then I wonder how he got chosen to be the ostensible mouthpiece.
