The singularity as a category of journalism: Convergences and divergences of theories of journalism, history and political sociology

Based in the categories of event and narrative, the work compares the theoretical  route of the knowledge produced to understand journalism and the one performed by socio-historical thinking  in order to establish  epistemological similarities and differences of both.  Mainly for journalism, which is still seeking to build its theories. The emphasis is given to the possible approximation of history, sociology and journalism studies, from the category of singularity. Authors that propose to explain theoretically history, like Weber, Rickert, De Certau and Ricouer use the category, the same way that Genro Filho, Brazilian researcher, makes in his propose of theory of Journalism. The theoretical exercise shown here is result of research that observed how the works in History of Journalism in Brazil to usually neglect relevant concepts to Journalism in its researches and seek conceptual foundations of sociology and language studies to support their concepts.
