Abstract
A large amount of research in mental health care relates to the notion of trust, as a possible common factor in psychopathology, and as a common dimension of psychotherapeutic alliance, underlying the various therapeutic methods. Such hypotheses call for a more detailed analysis of this notion of trust. The paper seeks to shed light on this issue by confronting the clinical and phenomenological approaches. We propose to focus on three issues at stake: 1/ the issue of the existence of a tacit or pre-reflective trust, which can be defined by a phenomenological method. 2/ the issue of a foundation of trust in empathy, which questions the debates about empathy in phenomenological works. 3/ the issue of a structural self-opacity, brought to light through the paradoxical structure of trust, and that we propose to tackle with the notions of attestation and narrative identity.
