The practice of writing is not autogenous. It doesn't arise from within or from a thing itself.
Nor is it autonomous. It doesn't exist apart.
The practice of writing is interstitial. It arises between and in the midst of things.
Concepts are things.
Relations are things.
Desires are things.
Practice is, I'd venture, life itself.
I'd venture, idventure.
You say stomata.
