You gave us a really great overview of the chapters. I have to say that I enjoyed the most Chapter 5 because of the answers and the stories told by Myshkin.

Of course Chapter 4, that is like a backstory, gives us a lot of info about Nastasia, but in Chapter 5 some views and experiences of Dostoyevsky's himself come into the surface.

Also a memorable quote for me, regarding the story about the man sentenced to death, was the following: "The repugnance to what must ensue almost immediately, and the uncertainty, were dreadful, he said; but worst of all was the idea, ‘What should I do if I were not to die now? What if I were to return to life again? What an eternity of days, and all mine! How I should grudge and count up every minute of it, so as to waste not a single instant!’ He said that this thought weighed so upon him and became such a terrible burden upon his brain that he could not bear it, and wished they would shoot him quickly and have done with it".

Another one is the dialogue of Aglaya and Myshkin, when Aglaya states that "one cannot live and count each moment; say what you like, but one cannot. That is true, said the prince, I have thought so myself. And yet, why shouldn’t one do it?"

Finally, I think that we haven't learned yet the advice Myshkin wants from the General, he tries like four times to ask him but never succeeds!
