The Grunion and Z Philosophize

On a recent trip about town...

GRUNION:  Yo, Z!  Let's hit the playground and then eat some cheese dip and ice cream.
Z:  Word.  Hmmm.  This fence looks locked or something.  Are we allowed in here?

GRUNION:  Totally.  Watch me lock pick this piece.

 
Z:  Doesn't this violate the social contract?
GRUNION:  Free will, dude!

 
Z:  Free will is a myth cause our minds are made up of atoms and molecules that behave in probabilistic ways.
GRUNION:  Dude, don't tell me you're a determinist!

 
Z:  Don't label me, bro.  I just know that I know nothing.
GRUNION: Don't throw Socrates at me!  Besides, RUSH settled this in 1980.
Z:  RUSH is overrated.

GRUNION:  So you're saying that everything we do is predetermined?
Z:  Pretty much.

GRUNION:  Even though we just decided like five minutes ago to get cheese dip?
Z:  Yup.

GRUNION:  But what about when we do crazy stuff?
Z:  What?  Like put a chip on my head like this?

GRUNION:  Yeah!  How is that predetermined?
Z:  Cause I was destined to put that chip on my head precisely at this time and place.

GRUNION:  I dunno dude.  I think that fact that not deciding still indicates a choice pretty much proves free will.
Z:  What about the recent studies in neuroscience that indicate that our brains make decisions even before we're conscious of them?
GRUNION:  Too weird.  Makes my brain freeze.  Or maybe it's the cream.

Z:  Face it.  You gotta just go with the flow, man.  Everything is planned out.
GRUNION:  So why can't we just  go with the flow by eating cheese dip and ice cream every day?
Z:  The social contract, dude.  And also parents.

GRUNION:  Rousseau said it best, my man.  Man is born free, and is everywhere in chains.

Z:  You said somethin' there, brother.
