[Pathologic cognitive dysharmonies (nosographical pleasure or cognitive analysis)]

In this article we question the validity of the notion of pathological cognitive dysharmonies as developed by B. Gibello on the basis of Piaget's conception of development. We wish to emphasize the following points: 1) that it constitutes in fact a deviation from Piagetian theory; 2) that recent research has lead to a new perspective on development which relativizes the so-called abnormality of cognitive discordances. The very idea of classifying intellectual disturbances is criticized. We also thoroughly analyze the notion of container and emphasize its potential danger when applied in a syncretic manner.
