In the history of philosophy, there are many testimonies about disagreement between inspiring figures and their followers that were compared to parricides. The most famous of them all was that of Plato and his “Father Parmenides.” In the twentieth century, there is an echo that recalls that primal parricide in the Heideggerian defection from the Husserlian views. In this work, we will review the autobiographical hints in the attempts of self-presentation of the transcendental phenomenology developed by Husserl through the topic of “philosophical solitude.” Then, we will analyse the episode that led to Heidegger’s departure and its impact in the last period of Husserl. Finally, we will evaluate their contrasting perspectives as different models to understand the development of phenomenology.
