The text focuses on the concept of intersubjectivity and its current importance for guiding community actions and the construction of new social practices. Authors are presented who have an epistemological reference in the focus of interrelationships, privileging the field of interaction as the locus in which encounters, mismatches, problems and solutions to human issues occur. The concepts of Jacob Levy Moreno, creator of psychodrama, are indicated to support the emphasis that there is no possibility of one man alone, there will always be man and the other, a role and its counter role. Still, affectivity is one of the nuclei that generates bonds and the development of groups, and the greatest expression of affectivity is the release of spontaneity-creativity.
