Britannica: "De Morgan introduced the enormously influential notion of a possibly arbitrary and stipulated "universe of discourse" that was used by later Booleans. (Boole's original universe referred simply to "all things.") This view influenced 20th-century logical semantics.

De Morgan was one of the founders of modern mathematical logic, and Formal Logic is his principal contribution to the field, "the work in which DeMorgan took the first steps to codify logic into an algebraic system. He was not entirely successful, and it was George Boole who devised the first really workable system a few years later. In his research, DeMorgan had consulted the Scottish philosopher Sir William Hamilton on the history of logic, and Hamilton later accused him of plagiarizing his idea of a qualified predicate. His reply to this charge was printed in one of his regular Athenaeum magazine columns and in his book A budget of… Read More
