Existentialism

One of the things that I find so interesting about existentialism is that it is both much darker and much more clear than many of the philosophies that had come before it. While books with names like "The Phenomenology of Spirit" may have some kind of academic value, the sheer degree to which it is masked by techniques such as making up words like "phenomenology" degrades much of that value.
Existentialism, on the other hand, strikes me as vaguely sensible - they seem to know what they're talking about, and the absurd, the other, and the idea that you create your own sense of morality are all fairly well-defined. I like existentialism, if in part because it appeals to my sense of the emptiness of conventional, universal morality.
