The aim of this article is to question some concepts (structure, subject, determinism and changes) in the field of social sciences, understanding them as fundamental for studies on community health. The central objective here is to deal with subjectivity and subject. To do so, we refer to the historical contexts and theoretic fields where these questions are discussed, always in counterpoised pairs or, in some modern approaches, we try to integrate them into a complex universe. It is the way, after all, that social reality is presented and, consequently, the reality of health highly responsible for investigations and advances in the world of science and in life.
