Normativity represents an epistemological reference of the science of history, defined by the existence of laws, principles, leading to the scientific truth. The present study debates upon the cognoscibility of the history’s truth, starting from the neo-classical theories – the correspondence and the coherence theory of truth. The relation between historical facts and scientifically truth relay on the following: the historical research is based on sources; the cultural paradigm and subjectivity of the researcher may influence, but they certainly do not determine the historical truth. Normativity in history is defined by the theory of the historical cycles, with reference to a metaphysical structure of history or by the theory of historical series.
