To write is perhaps to ... select the whispering voices, to gather the tribes and secret idioms from which I extract something I call my Self ... A schizophrenic said: 'I heard voices say: he is conscious of life'. In this sense, there is indeed a schizophrenic cogito, but it is a cogito that makes self-consciousness ... a result of indirect discourse. My direct discourse is still the free indirect discourse running through me, coming from other worlds or other planets. that is why so many artists and writers have been tempted by the seance table.
