Firstly, there has been a lot of impressions that the novel offered a simple idea of whether there is a god or not (see the two previous posts and comments. A more interesting angle was how did believe or the degree of believe affect the different members.
However, I really like the quote that was brought up in class "whatever the truth is, blessed be the truth". While this would probably be seen, and may have been written, as a religious statement, I see it as more of a statement of acceptence of the world and of its beauty, separate or with something religious. While goodness and truth were brought up in the conversation, they were discussed as founding blocks and intrinsically connected with theistic models of world view. While religion is the main theme, whether something is good or not can have absolutely nothing to do with religion, even in a theisticly questioning novel.
One thing I really did enjoy about these two novels was how differently they approached he fact of dealing with and finding of a new world. Although she went very little into the actual what would have happened on Earth as an effect of the discovery in terms of technology, business and exploration, I still found it refreshing. Immersed in Star Trek for my humans making contact literature, the amount of change on Rakath that occurred because of human landing at first felt very wrong, especially once Sophie started to directly influence the settlement she was with. What this really reveled to me is that the question is actually why not participate? In Star Trek, working on a non-warp drive world is considered interfering, while here it was presented much more as if Sophie was participating and doing her part.
