Abstract: This conference explores the main concepts and the gnoseological perspective assumed in the work of history of the ideas and the political thought, of Professor Rodriguez Iturbe. Its main goal is to make, in the first place, a brief presentation of the main subjects and topics developed in this work, along with the different forms of analyses used by the author. The lecture deals then with the different types of writing history, the distinction between narration of events and the participation of the historian in this narration, the influence of ideologies in some authors, the fallacy of the immanentization of eschatology in which some of them incur, and the Gnostic perspective that this type of serves as sustenance. In the final part of the writing, the lecture establishes that the work of Prof. Rodriguez Iturbe has a deep therapeutic sense in comparison to histories written by authors like the previous ones, because its vocation to Truth has allowed him to carry out a study without any reductionism, and with a clear sense of unification. It ends with a reference to the virtues of the historian, and the meaning in History, immanent and transcendent, which supports the concepts and developments of the work written by Rodriguez Iturbe.
