What do we mean when we talk about cogito sum? What do these words refer to in their use? How did they appear for the first time? How have they progressed and at the same time the progress of which concepts they are? This paper aims to research cogito sum’s form and concept. Therefore, it asks about the formal and conceptual structure of cogito sum in order to move towards the questionable aspect of the cogito sum question, ie “Being”. Hence this paper is a step towards providing the possibility of dialogue with this philosophical concept, that is, the possibility of answering it on the way of necessity aspect of philosophical questioning. The aim is to find a set of contributions to this philosophical concept, through the texts that significate the questioning aspect of Cogito sum. Based on tradition, the subject is gathered by Martin Heidegger. Thus, it makes this step possible with respect to a part of Heidegger's encounter with this question.
