Traumatic experiences do not merely impact on the individual’s body and psyche, they alter the way we experience others, our interpersonal relationships, and how we make sense of the world. In my dissertation, I integrate work in phenomenology, psychopathology, philosophy of mind, philosophy of psychiatry, and trauma studies, and draw on trauma testimonies ob- tained in an online questionnaire. I engage analytically with the question of what constitutes a trauma, whether psychological trauma is necessarily pathological, and what the causal and (...) im- plicatory relations between traumatising and post-traumatic experiences are. Informed by these preliminary elaborations, I focus on the intersubjective dimension of trauma, drawing on a qualitative study I conducted in 2020. I show that empathic abilities may be altered but are not necessarily diminished through traumatising experiences; I suggest a framework for under- standing feelings of alienation in the aftermath of trauma; and I demonstrate how feelings of belonging may be re-established. My dissertation is exemplary of how phenomenological frameworks can contribute to a better understanding of psychological trauma and that engaging with trauma can, in turn, inform and enrich philosophical thinking.
