<i>Physis</i>, <i>logos</i>, history: Husserl and Merleau-Ponty on the historicity of rationality

<p dir="ltr">In this thesis, I argue that late Merleau-Ponty's transformation of post-Husserlian phenomenology, based on his ontological shift, leads to a depiction of the historicity of rationality in which the Presocratic notion of <i>element </i>can be considered as having a key importance. The problem of the historicity of rationality applies to any period in human history. However, the thesis focuses on Western history and philosophy and argues that the "Presocratic moment", is crucial for an elucidation of a Merleau-Pontian approach to historicity. The first part examines the work of Husserl, delineating a tension between his notion of transcendental subjectivity and the field of operative intentionality, a tension that is reflected in Husserl’s account of the historicity of rationality. This critical analysis of Husserlian phenomenology helps to emphasize how Merleau-Ponty's late ontology overcomes these tensions through the implications of a circular interconnectedness between <i>physis</i>, <i>logos </i>and history. Following a teleological reading of Merleau-Ponty's <i>Structure of Behaviour and Phenomenology of Perception</i> from the perspective of his late ontology, the third and most important part of the thesis tries to show that Merleau-Ponty's concept of flesh and his retrieval of the Presocratic notion of element, both taken as two key milestones in the history of rationality, provide us with a better understanding of the key notion of a vertical history of wild Being. The thesis presents a formal model to understand this crucial notion, as an ongoing historical and cultural flow that has the shape of a double-edged spiral circularity combining vertical ontological depth and horizontal symbolic distance.</p>
