When I write artistically, I write in many voices. Could me yours, somebody else’s or mine.
The goal is to communicate the human animal’s and the non-human animal’s experience.
When I use the word “I”, once again it could be you, somebody else or me speaking. In that sense I assume a conduit role to communicate what I think is meaningful to all humans and/or non-human animals.
It doesn’t really matter where the voice comes from, since we all share the animal experience.
