It just sort of resonates with me? Woh, that sounds too new-agey! Um... I can identify with it? No, that's not it either. It speaks to my soul? I dunno... Let me put it this way, of all the books that I've read, it's the only one that ever got an emotional reaction out of me, not so much because I was wrapped up in the character(s), but mostly because I was wrapped up in the unfolding of ideas and the expressions of what it means to exist for some. And perhaps I catch a glimpse of myself, the worst part of myself, in the underground man.
