At the beginning of the first chapter of The Sickness Unto Death we find the paragraph
Man is spirit. But what is spirit? Spirit is the self. But what is the self? The self is a relation which relates itself to its own self, or it is that in the relation [which accounts for it] that the relation relates itself to its own self; the self is not the relation but [consists in the fact] that the relation relates itself to its own self. Man is a synthesis of the infinite and the finite, of the temporal and the eternal, of freedom and necessity, in short it is a synthesis. A synthesis is a relation between two factors. So regarded, man is not yet a self.
(The bracketed bits were bracketed in the text.)
So far I think I've figured out what he means by some of the last stuff. When he's talking about how man is a synthesis, he means between spirit and body. Therefore man is a relation. But "a relation which relates itself to its own self" is a little harder to grasp. And I'm not sure why man is not yet a self when regarded in this way. It's dialectical, almost definitely, but it doesn't sound like the parts of Hegel I've read on consciousness and the will---the intro to Philosophy of Right.
Anyway, I stopped reading there and decided to ask for help. What does this mean?
