someone wrote something about Sartre's "Nausea" and I pasted it below....
Freedom is frightening, and it is easier to run from it into the safety of roles and realities that are defined by society, or even by your own past. To be free is to be thrown into existence with no "human nature" as an essence to define you, and no definition of the reality into which you are thrown, either. To accept this freedom is to live "authentically"; but most of us run from authenticity. In the most ordinary affairs of daily life, we face the challenge of authentic choice, and the temptation of comfortable inauthenticity.
