"There is a philosophical question as to what one really sees'¹. Wittgenstein's remark raises all sorts of questions: Does one see tables and chairs, people jumping up and down, their jumps, their sadness? Does one see colours and forms, coloured forms, dynamic and static, that are above or to the left of other coloured forms? If the latter, are these things one sees private entities or public entities as are, presumably, tables and chairs? If both answers are legitimate (sometimes, or whenever we see?) what are the relations between the people we see and the coloured forms that we also see? In other words, is what is presented to me in my visual field private, public or partly private and partly public?
