This paper aims at a phenomenological analysis of trust. We argue that trust has a transcendental dimension in that it functions as a condition of possibility of the basic ego-world relation. Tacit for the most part in ordinary experience, it comes forth in its problematicity in schizophrenia spectrum disorders. People experiencing psychic disturbances lose trust in the continuity and the mineness of lived experience and conceive the world as uninhabitable. In order to address the transcendental problem of trust, we first (...) carry out a static analysis of trust as perceptual faith and we show that it is founded in the functioning of a transcendental ground. In a second step, we proceed with a genetic analysis drawing on Husserl’s manuscripts on the awakening of the self, on early childhood, and Richir’s recent phenomenological readings of D. W. Winnicott. We situate the archaic experience of trust in an originarily intersubjective and affective dimension, where the parental environment functions as a transcendental matrix for the early development of a yet inchoative self. By doing so, we aim to sketch out the major lines of a transcendental history of trust in the early stages of human experience. (shrink)
