In the year of 1972 the Society for Psychical Research invented a imaginary spirit called philip and provided him with a history. It wasn't too long before they started to hear from Philip. The proponents of "Super Esp" believed this particular case supported the existence of "Super Esp". A good counter argument to this it could of been a low- level spirit.
Allan Kardec book in 1872 called "The Book of Mediums". Here is a comment he had to say about it possibly being a low-level spirit.
“Invoke a stone and it will answer you. There is always a crowd of spirits ready to speak for anything….If you invoke a myth, or an allegorical personage, it will answer; that is, it will be answered for, and the spirit who would present himself would take its character and appearance. One day, a person took a fancy to invoke Tartufe, and Tartufe came immediately; still more, he talked of Orgon, Of Elmire, of Damis, and of Valire, of whom he gave news; as to himself, he counterfeited the hypocrite with as much art as if Tartufe had been a real personage. Afterward, he said he was the spirit of an actor who had played the character. Trifling spirits always profit by the inexperience of interrogators, but they take good care never to address those who they know are enlightened enough to discover their impostures, and who would give no credit to their stories.”
Also the super psi proponents obviously forget that like physical beings, our spiritual beings can have an imagination to say they are somebody their not.
By the way, i got this from Michael E Tymn but paraphrase it in my own words here.
