This article presents considerations about what it means to do science within the context of qualitative methods and techniques in sociology. It is founded on the conception of methodology as the critical knowledge of the ways of the scientific process, a knowledge that questions and investigates its own limits and possibilities, and also on the recognition that all sociological knowledge has at its basis a commitment to values. Qualitative research is defined by its stress on the analysis of micro-processes through the study of individual and group social actions, carrying out an intensive assessment of data, and characterized by heterodoxy in the analysis. It emphasizes the need for the exercise of intuition and imagination by the sociologist, in a kind of handmade work, seen not only as a condition for an in-depth analysis, but also - and that is very important - for the freedom of the intellectual. The main criticisms made against qualitative research are discussed, especially the allegations of lack of representativeness and possibilities for generalization; of subjectivity due to the closeness between researcher and researched, and the descriptive and narrative character of its results. Within this context, considerations are made on the ethical problems involved in this kind of research, and a brief review is made of the history that culminated in the dominance of the quantitative approach, particularly in the postwar North American sociology. The text concludes by proposing that it is most important today to produce knowledge that, besides being useful, is also explicitly oriented by an ethical project aiming at solidarity, harmony and creativity.
