This is column number nine in the series. We take as our theme the recent movie ‘The Matrix’. The Matrix is a cinematic exercise in virtual reality and virtual logic. It is not necessary to have seen the film to read this essay. The Matrix is all around you. It is in the air you breathe, in the ground you walk on, in the sights you see and in the feelings that you feel. You yourself are composed of it just as much as it is composed of you. You imagine yourself to be an observer independent of the Matrix, but the very possibility of your observation, your sense of Self and World is produced by the Matrix .
