The perception of other people and the intersubjective world is problematic only for adults. The child lives in a world which he unhesitatingly believes accessible to all around him. He has no awares of himself or of others as private subjectives, nor does he suspect that all of us, himself included, are limited to one certain point of view of the world. That is why he subjects neither his thoughts, in which he believes as they present themselves, to any sort of criticism. He has no knowledge of points of view. For him men are empty heads turned towards one single, self-evident world where everything takes place, even dreams, which are, he thinks, in his room, and even thinking, since it is not distinct from words.
