It treats to argue the designed theme as "the Construction of the History of the Nursing Know " with two objectives: 1. to contribute in the magnifying of the space of the researchers of the nursing justifying its rights related to the objects of study linked to the discipline of professional formation - Nursing and History of the Nursing; and 2, to stand out concepts for a epistemology of the nursing considering aspects of the construction of the knowledge potentials to reduce difficulties in the research of nursing, specially in the interest of the history of the Brazilian nursing. The approach come from the intellectual attitude face to the subject and is placed according to a coherent critical position with conjectures and reflections concerning the epistemological aspects detached in the construction of the professional knowledge, with more relevancies on the thinking about Nursing - its known and its history. The considerations aim at the idea represented by the question of knowledge in construction in the half way between subjectivity and objectivity - epistemological aspects of these knowledge, and as they occur in the epistemic field. The Nursing and the History of the Nursing are focused as a set of elements related to social practice of the profession and others consolidated in the historical determination. The author treats the theme on the basis of epistemological concepts (Canguilhem and Barchelard) relatively to that it must be understood as "history of sciences" and in a perspective of what can be understood as "the present time of the history of sciences".
