Ghosts are a recurring shadowy theme throughout history. Pliny the Younger (Gaius Plinius Caecilius Secundus) is reported to have written in 100 AD about a ghost hunt that occurred some years prior in Athens. Thomas Edison was experimenting on a way to communicate with the dead. The Bible also warns Christians not to pray to the dead. To believe an individual has a soul or to believe in the trinity of The Father, The Son, and the Holy Ghost is an admission of a belief in at least a Holy Ghost and therefore the possibility of ghosts or ghostly spirits or spirits as all are descriptions for a spirit. Belief in The Great Spirit, in Atman and Brahman is a belief in spirits. To believe in any form of an afterlife is a belief in spirits. Calling a grape red, green, or purple only changes a description; it is still a grape. Can we be taken seriously if we state that we only believe that concord grapes exist?
The Pursuit of why has brought the human race to the point it is at today in every walk of life including but not nearly limited to religion, horticulture, medical breakthroughs, rocket science, to the study of the mind in which we barely have a rudimentary grasp. The historical search for the existence of ghosts is part of the human condition search for answers to the question of why. Technology that we invent allow us to lean more about our existence. I believe that technology will eventually answer questions of proof regarding ghosts. Perhaps we need to invent that technology yet. I wonder if ghosts believe in humans. As for me, I continue to search the shadows pondering the question of why.
