Cyberlaw applies and challenges traditional legal concepts and principles in the context of the cyberspace.There are two basic view points. The first, exceptionalism, believes that traditional rules and principles of law in physical space do not work in cyberspace. The second, unexceptionalism, believes that traditional rules and principles can and should be applied to cyberspace.
A correlary issue is whether a behavioral model recognizing several modalities (Lessig's model illustrated top center column) affects the behavior in cyberspace or whether a market based/economic model should prevail (Judge Easterbrook's model, illustrated bottom center column).
