How will the researcher behave when he decides to invest a field? What will be its starting point? How should he observe his object? The exercise is not easy and every researcher, every student, knows at this stage that he cannot ignore this questioning. If the writing work will give substance and consistency to the action in a second step, the confirmed or apprentice researcher must first ask himself about the posture to adopt because he has the heavy responsibility of establishing the theoretical base upstream on which he will build the rest of his research.
