Relying on both conceptions, H. Grivois's phenomenological description of e
merging psychoses and L. Binswanger's theory of Presence's stream, this pap
er tries to question the possibility of a clinical invariant and therefore,
a typology of acute psychoses. The topic is defining "centrality" (psychot
ic experience of being a focus point) as an anthropological disproportion,
as one form of missed Presence which could be specific of emerging psychose
s, and studying it from the viewpoint of lived space and intersubjectivity
for patients with psychoses.
