 Critics argue that information is not the kind of thing that can be owned or possessed and is not something that can be property, as that notion is typically defined. Information objects, such as numbers and propositions are abstract objects, which cannot causally interact with material objects, and hence cannot be owned or possessed. The idea, for example, that one could, in the relevant sense, possess and hence own the novel expressed by the book A Tale of Two Cities makes as little sense as the idea that one could possess and hence own the entity denoted by the symbol “2.” Whatever concepts might properly be applied to abstract objects, on this view, the concept of property, according to these theorists, does not. As a conceptual matter, the term “intellectual property,” at best, applies to nothing and, at worst, is incoherent.
