This paper proposes to discuss the notions of quality and quantity within the cartographic research, with emphasis on the latter. These are articulated in ethical-political direction of an inseparability plan of forms and forces, not restricted to dichotomous perspective between "quality" and "quantity". From two cases of research in their specific strategies, a psychological test and a questionnaire measuring mild mental disorders, seeks to problematize the effects of quantitative operation as one of the possible clues to the method of cartography: the notion of quantitative as a quantum forces and the notion of qualitative as differential between quanta of forces, in a real production.
