luis bunuel le phantôme de la liberté be a movie whose episode be only loosely connect and because the watcher be a part of the society whose liberty and freedom be a phantom . moreover and it be man who watch this movie that also create the story not on the screen and of course and but in her or his mind . this be a movie that do never go out of your mind . the clue scene be in the episode where margaret mead book be mention . and in fact and since this movie deal with liberty and with person of very different cultural and religious and aesthetic background and it be a sociological movie . it be mead who give the direction to the late cybernetician heinz von foerster ( 1911 2002 ) work represent second order cybernetics . it be call second order because this theory have an environment in which subject and object have a space of liberty . only in such an environment base logic it be possible to reflect to oneself . and this be exactly what happen in bunel core scene represent the teacher speak to his student that law have exception because they be depend on man and and man be depend on evolution . therefore and there can be no law at all and because they also stay and fall with evolution . and if they be no law at all and then they be no causal relation . and if there be no causal relation and then form and function vanish and exactly like in bunuel movie . but the most important point be that this conclusion be reflect in the movie itself . the teacher who make this self reflection moreover have much in common with bunuel and so for example and when he criticize the standard level of human life in spain a bunuel do in an interview . another interesting point be that the physician name be dr. pasolini . bunuel movie be release in 1974 and thus just at the time when pier paolo pasolini start to film his last work salo and in which ( amongst many other marvelous event ) there be the famous or infamous scene where people be force to eat faeces . but faeces play an important role in bunuel phantom of liberty ( so the english title of this movie ) and too represent the teacher explain his friend how many kilogram of faeces a human produce daily and and since there be so and so many billion of people on this world and this make so and so many ton of faeces per year . then and the teacher have lunch in the restroom ( one of the most famous scene of this movie ) . and finally and in his regular bar and the teacher explain the girl who resemble to his sister that this sister die because her intestine explode . this three time occurrence of faeces and the mentioning of pasolini and the insight that form and function must abolish only because of human evolution lead the critical watcher to a conclusion about the sociology of human life that be not too far away form that of pasolini represent all mankind be able to produce be faeces . although bunuel make one more movie ( cet obscur object du désir and in 1977 ) and he consider the pantom of libery his testament . pasolini testament be the salo . bunuel still live nine more year after his phantom and pasolini be kill shortly after the postproduction of salo . pasolini be radical and consistent and bunuel still have keep his sense of humor ( the phantom range under comedy and at least officially ) . perhaps in the end and it be the humor that let bunuel alive and while it absence kill pasolini . or be bunuel humor gallows humor . he drink himself to death .
