I have read Sartre -- please, do not pretend that he is well written. It's an insult... It was at that point that you lost your credibility.
Unfortunately, my interest in philosophy is a passing hobbie. I could not afford college so I joined the Army.
But anyhow -- I am delineating them in terms that I think make sense, being that I think of Nietzsche as an overly cited crutch for teenage left wingers trying to defame my religion. I speak not of conservative and liberal in a political sense, but in a social sense.
And Dr. Frank is a very valid source. There are few things as profound as punk rock music in the world.

I think philosophy is hurting because everything worthwhile of being said has already been said. As it was written in 500 BC by Solomon, "nothing is new under the sun."
