Le problème de l'altérité dans les «Recherches logiques» de Edmund Husserl

There is not a single occurrence of the word 'Intersubjektivitat' in Husserl's Logical Investigations but this concept had come classical in neo-kantian schools at the end of the 19th century. Actually, Husserl developed an equivalent to this neo-kantian theory of intersubjectivity in his own Logical Investigations but he called it a theory of 'supersubjectivity'. Moreover, it has often been noticed that he proposed a theory of linguistic communication int he Logical Investigations and it is generally considered that the seeds of his theory of intersubjectivity are to be found there. The paper tries to show that an important hapax occurred in Husserl's line of thought at the beginning of the 20th century. He gave up the scheme of the Logical Investigations, according to which supersubjectivity grounds intersubjectivity, and favoured the opposite solution instead.
