Pain ...
Studied analytical Phil at Undergrad and struggled with what's well captured in this joke:
"To do maths you need pen, paper and a wastebasket. For philosophy, the pen and paper are enough."
There's just so much noise, even in it's supposedly distilled analytical form. The stuff worth a damn e.g ontology, possible world semantics, epistemological logic, etc quickly finds its way out into another field.
It's there, the value is there, it's just all that damned noise is too.
