In Chapter Three of the novel 'Lord of the Flies' by William Golding, we find out that one of Simon's personality traits is that is helpful. Another is his his loyalty. There is a lot of discussion about meetings, decisions, projects and implementation. The three boys discuss the fact that ony the first bit gets done - the meeting - where everything is only talk. Afterwards, after some 'batty' suggestions as to what their neaxt project should be, the younger boys hang around for five minutes and then run off to play. Jack complains that 'no-one helps.' Ralph sticks up for Simon by telling Jackthat Simon has been helping him all day. The fact that he stayed by his side shows loyalty as well. Jack is guilty too as his 'play' involves killing.
I think what we find out about Simon in this chapter is that he is different from anyone else on the island. He is able to sort of see things that other people can't see. We can tell this from what happens at the end of the chapter. He goes off and he finds that little secret place of his. Once he enters, he sees the whole world in a different sort of way, almost like he's having a vision.
This has nothing to do with the parliamentary system. I think the commentary on that comes earlier in the chapter when Ralph talks about how pointless their meetings are. This implies that Golding feels the same about Parliament.
