I don't know much about it formally (and really, who does?) but I do find myself leaning towards the Absurd, I don't see any higher objective meaning to existence other than that which we, with our gloriously limited minds, choose to assign to it and when we do, the Absurd will make sure that meaning gets steamrolled at the earliest opportunity.

When we do it in groups, we call it "society" or "religion" or "culture" and when we do it as individuals we are called "insane" lol.

The Absurd is the one constant truth in the world imo and will always assert itself whenever we try to suppress it.

I haven't done much reading beyond the big names but I do know a good joke about Sartre...

Sartre was sitting in a cafe when a waitress approached him: "Can I get you something to drink?"

Sartre says, "I'd like a cup of coffee with sugar, but no cream".

The waitress goes to get the order and comes back and says "I'm sorry sir, we are all out of cream -- how about with no milk?"

Eh? I like that one.

If I'm honest my favorite existential philosopher is the Joker, he gets it.
