The possibilities of research of subjectivity, corporeality, and intersubjectivity are widened by taking into account feminist optics to include significant phenomena and experiences that both enrich and deepen the framework of phenomenological inquiry of the self, agency, and being in the world. We can find the starting points of feminist phenomenology in the works of E. Stein, M. Merleau-Ponty, S. de Beauvoir, E. Levinas, and others, as well as in contemporary interpretations and new treatments such as those of S. Heinämaa, L. Fisher, and A. Al-Saji. The thesis therefore presupposes knowledge of phenomenological philosophy and phenomenological method, as well as familiarity with contemporary debates within critical and feminist phenomenology.
