A nice crash course...
...in metaphysics and epistemology.
Before you ask who,how and why I am you have to ask it about the universe. It has to have some effect on us, as we in turn affect it. Without knowing about someething that, in part, governs the self we will never know what the self actually is.
Nice philosophy really, but you seem like a smart guy so i suggest you read some of Hegel's work in phenomenology. That stuff is a real mind-fuck.
