This idea of the constitution of matter was perhaps the worst of all. These imponderable fluids were mere names, and these forces were suppositions, representing no

As masses with similar charges (i.e. both positive or both negative) will repel each other, an "electric fluid" was conceived to explain the effect: "the fluid diffused on the one ball repels
