convoluted writing in academic philosophy: an illustration

This is why academic philosophy is so hard to read: writers get lazy / used to writing in unnecessarily convoluted ways. For example:

"whose necessity resides in enabling the performance of..."

Write this instead:

"...mere linguistic devices that we need to perform..."

Seriously!
