Nietzsche and Dostoevsky

So, we're reading Dostoevsky's Notes from Underground in my course on the literature of existentialism right now.  Nietzsche was fascinated with Dostoevsky, particularly his psychological insights (which are... well... so realistic it's terrifying).  I keep thinking about the intersections of this book and Dawn, which begins with this passage:

In this book you will discover a 'subterranean man' at work, one who tunnels and mines and undermines. You will see him  presupposing you have eyes capable of seeing this work in the depths  going forward slowly, cautiously, gently inexorable, without betraying very much of the distress which any protracted deprivation of light and air must entail; you might even call him contented, working there in the dark. Does it not seem as though some faith were leading him on, some consolation offering him compensation? As though he perhaps desires this prolonged obscurity, desires to be incomprehensible, concealed, enigmatic, because he knows what he will thereby also acquire: his own morning, his own redemption, his own daybreak? . . . He will return, that is certain: do not ask him what he is looking for down there, he will tell you himself of his own accord, this seeming Trophonius1 and subterranean, as soon as he has 'become a man' again. Being silent is something one completely unlearns if, like him, one has been for so long a solitary mole.

In Notes from Underground, the main character is so completely disheartened with society that he takes himself out of the game, as it were.  Not suicide, just social suicide (which he describes in excruciating detail... ugh it's so painful... it makes Nietzsche's relationship with Wagner seem almost healthy).  This reminds me very much of our conversation in class yesterday... is it inevitable, when a person sees the world the way Dostoevsky or Nietzsche does, with a kind of magnified clarity of the games we play to make meaning, that that person is going to end up completely alienated, isolated, incapable of intimacy?  

I came across this article, which may or may not be interesting:

The whole notion of transhumanism, and how this might relate or not relate to the ubermensch is fascinating to me.  I tend to think that both Nietzsche and Dostoevsky would be really put off by this.  Not connecting my thoughts particularly well... just throwing these ideas out there!
