Estrutura e ontologia no 'Prefácio' da 'Fenomenologia da Percepção'

Working on the Preface of Phenomenology of Perception, this text seeks to explain the presence of two fundamental operators since the beginning of Merleau-Ponty's reflection. On the one hand, the notion of structure, and, on the other hand, related to it, the presence of an ontological problematization, already present in the way in which the author incorporates the phenomenological project.
