Participants in analytic treatment can be seen from different perspectives, that is as people, as individuals and as subjects, with different meanings and implications. The work tries to show how the treatment, starting from the preliminary interviews, aims at regulate the importance of the person, that is the individual in his socio-cultural dimension normed in attitudes and language, in favour of the individual in his specific peculiarity. This regulatory process, consisting of an impersonalisation that marginalises the person, aims at creating the conditions for the individual and the analytical couple to come into contact with another dimension of the impersonal; that is the unconscious. The two levels of the impersonal, the supra-personal level of socio-cultural norms and the sub-personal level of the unconscious, delimit a space in which the relationship, the transference and the general analytical process give rise to processes of becoming a subject, subjectivation. In this perspective the analytic psychic space is shown to be endowed not only with extension but also with the property of being a ‘place’ that defines, and is defined by, an event of subjectivation. It is shown how the term ‘heterotopic space’ is appropriated for this place and the general analytic device.
