E. C. Rogers

Edward Coit Rogers (February 2, 1816 - November 11, 1860) was an American physician, abolitionist, and originator of an explanation of spiritualist phenomena that he called "the Philosophy of Mysterious Agents," a theory that holds such phenomena is due to the unconscious effects of unknown but physical, measurable forces (such as Reichenbach's odic force) acting directly upon the brain (which he compares to the influence of narcotics), as opposed to wilful, otherworldly powers and principalities.
