Influence

In mediumistic terminology influence is equivalent to "spirit." The American medium Lenora Piper applied it to objects that, by virtue of association of ideas or magnetism of the late owner, helped her to establish communication with the deceased. The presence of such objects, she declared, helped her to clear the ideas of the communicators. The term influence was used earlier by practitioners of animal magnetism to denote the mesmeric force between operator and subject.
