The paper first analyzes the ethical question of qualitative researches from the philosophical viewpoint, and the bioethical question as an interdisciplinary gap that enlarges from the seventies. Afterwards, the question on qualitative research considered as technique and art is raised and understood in a philosophical way of thinking science as a theoretical body, which is epistemically organized in the face of the social reality investigation, and as a movement instituted to defend and discuss the properties of these methodologies. Anthropology is used as an example, and some parts of the codes of professional ethics of anthropology, sociology and psychology are presented. Finally, particularities of the social science fields are discussed, as well as the need to develop a code of ethics for qualitative research. In addition, ethical ways to work in social researches are suggested.13351-60
