Intenzionalità concentriche, eccedenti, sprofondanti. Revisioni di un concetto fondamentale della fenomenologia

With reference to the analyses of the Fifth Logical Investigation, the first book of Ideas, the Fifth Cartesian Meditation and Grenzprobleme der Phänomenologie, the paper reconstructs a progressive broadening of the concept of intentionality from a linear model connecting the act of consciousness with the object, to a concentric model linking experience and world together, up to the idea of sinking intentionalities working at the threshold of the unconscious.
