Chris Wilson -- "The Judge in 'The Trial' (Pink's conscience) condemns Pink for selfishness and hurting people who loved him, and then sentences him to be exposed, which is what the album is: an exposure of Pink's narcissism. So, at the beginning of the album you are listening to the Judge's sentence: exposing Pink before his peers."
Shane -- "Wouldn't you think that it is totally reasonable to believe that the Rag doll representation of Pink during 'the Trial' could very well be due to the wall people associated with the song in general? You stated that the schoolmaster and mother figures are both playing upon the idea of the innocence and individuality of Pink's childhood. Also with the addition of the lyrics 'Toys in the attic' and all the rest of Pink's actual dialogue revolves around a very child-oriented basis. The rag-doll representation could simply be an extension of Pink longing for his lost childhood. The same with viewing the school master as a marionette. Both can be associated with youth. Also the representation of the wife could be reminiscent of his childood. Children would probably associate scorpions with something they would be afraid of, and this is fitting because her testimony is by far the most damaging of the three."
Author's Addendum: Interpreting the doll as a symbol of Pink's stunted childhood also provides a ready explanation for the clips of the large rag doll entangled in barbed wire...Pink's innocence is perpetually tied up with the death of his father on the battlefield.
Matt Schwager -- "After watching Pink Floyd: The Wall for about the billionth time, something struck me: You don't see any male reproductive parts in the movie until the judge makes his grand appearence on his stage. An explanation for this soon followed: Remember, Pink's mother corrupted his thinking. I think she corrupted the way he views women, so he views them as cheap toys or playthings, as seen in 'Young Lust.' Therefore, he sees no sacred value in their reproductive parts, and you can see this through the rampant female nudity throughout the film. Therefore, his view of the male organ is lifted into a more valued, sacred level, and is not seen until someone honorable (or in this case, simply powerful) is brought out, i.e. the judge."
Author's Addedum: Matt raises an interesting point that not only applies to the Wall (both film and movie), but to so much of the world's art, literature and music. One can easily say that Pink's internal representations of women are a result of his upbringing, but is this an intentional satirization of a largely patriarchal society's categorization of women, or an unintentional dissemination of it? Even in today's modern art and public life, women are often pigeonholed into two broad, stereotypical categories: the virgin and the whore - that is, the naively inexperienced or the vulgarly over-experienced. In movies, this can be found everywhere from the hooker with the heart of gold to the innocent waif who is always in need of saving by the strong leading man. Such stereotypes in the arts even carry over to public life, in which a strong yet stubbornly opinionated man is deemed a "leader" while an equally strong, opinionated woamn is deemed "ruthless," "conniving," or simply a "bitch." Correspondingly, all the women in the Wall are either sexual playthings (the groupie, the wife) or sacrificing, virginal martyrs (the mother). As mentioned above, the fact that there are no deeply developed women in either the album or movie can either be attributed to what may be Roger Waters' and the bands' own inherent mysoginism or, rather, an entirely intentional and satrical look at the absurd puritanism that still inhabits purportedly progressive Western thought.
"When Pink's Mother asks to take him home she cuddles him in arms made of bricks. This shows that often people can entrap others within their own walls, and can thus become bricks of each others wall. It's ironic that his mother is trying to trap him in her own protective wall, when this is what he is being tried for. Also this leads me to think that the wall symbol goes much further than self entrappment; say for example, love. We always know love as sharing and being together, but maybe love is just two people shring the same wall. And hate could be when teh walls of two people clash."
