Brève note historique sur le délire de supposition de Sérieux et Capgras

The delusion of supposition joins in a certain sense what as V. Magnan (1894) had described concerning the said phase of “incubation” of the systematic chronic delusion. The link must be also made with the more recent works of H. Grivois (concepts of “rising psychosis”, of “centrement”). This delusion leaves the subject in an uncomfortable, alarming position, because submitted constantly to the delirious threat of the world which surrounds him, without being able to bring to it a soothing, or definitive answer.
