To explain what I mean, in the first chronicles here are several of the big issues raised:
- The fundamental question of ethics - is it ok to do whatever you want, if you think you are dreaming? Or does it start to matter if the dream doesn't fade away? If you start to feel that the other people in the dream are in some sense real as well? (This goes into the whole issue of solipsism in philosophy.)
- Pacifism as a response to violence. This happens both when TC says he'll never kill again, and in another sense in the Oath of Peace. The Oath is an even bigger issue - you try to suppress strong emotions of any kind, for fear of what may result - Desecration - but then you also become weak. This builds and developers over the first three books extremely well.
- Rape. Can you ever atone for such a horrifying crime? Can others ever forgive you. Are you responsible if there are extenuating circumstances (it must be a dream, since leprosy can't be cured, etc.)?
I see one major issue dealt with in the last chronicles - the stubbornness of the masters. This is really a brilliant topic, and it goes all the way to showing us why they act as they do, to showing us how they persist in doing it even to our horror. And it takes 4 books and Kenaustin and killing a raver and Stave and the Ramen explaining stuff and so many other things to make even a dent in the Master's position. This felt like substantial, solid stuff.
Perhaps another issue is the recurring theme of "can good be achieved by evil means"? While a strong topic, not much happened to get into it, I feel.
And what else is there in the last chronicles? I feel like we were shown cool stuff (Demondim, Viles, Insequent, etc.), and there were great battles. But something felt empty. The battle of soaring woolhelven in LFB was also a great battle, but also the scene where Covenant killed and horrified himself by doing so, thus beginning the pacifism storyline. It was both a good battle and part of an issue the story raised and developed. Whereas in the last chronicles, good battles are mostly just good battles.
Am I wrong? Do I need to read it again to fully appreciate it?
