Who knows

[TranquillityBase]

Who knows

From the earth we came.
Into the earth we go.
Neither Plato nor Socrates
knew more about it than we know.

Nor the quaint aboriginal elder,            my only gripe is "quaint aboriginal elder", in particular "quaint"; how about "squatting"; I always see them squatting at a fire, passing on their wisdom.  "quaint" seems kind of superior sounding.
the Sentinelese with his bow,
nor the PhD from Boston,
the book writing Igbo,
the bullfighting Catalan
who wears it on his shoulder
as the bullring’s air grows colder  my favorite bit is the Catalan

know.

Very nice, especially the subtle rhymes, which I wasn't even aware of until I studied the poem more closely.  That's how rhymes should be, something I've yet to master.
