This article aims to approach the concept of rehumanization in a personalistic key and, from it, illuminate some new meaning to current philosophy and science. This concept arises not so much from a theory developed a priori and without contact with reality, but rather, it is the fruit of a practice coming from specific people who struggle to overcome a state of dehumanization. What we propose here, in short, is to explore a new personalist methodological path called rehumanizing personalism.
