In a dialectical cycle of theory and experience, the methodological model of Dialectical Empirical Realism (DER) evolves between mental practice and empirical knowledge. The circular articulation between data/theory enables the researcher to disentangle the data into essences, refining the theory manifoldly with the aim of creating a substantial, conceptual network that will free him from secondary, theoretical findings and linguistic neologisms as often happens in post-modern theories of the social world. In this way, the development of new concepts is avoided, which in most cases, especially in post-modern theory, is the result of conceptual transformations that are fed with mainly ready-made data from the public sphere and the economy, which are however determined by analogous pre-existing or co-existing conceptualizations of current theory and established everyday life.
