Philosophy is conceptual notation, the art of writing down how we think; poetry is emotional notation, the art of writing down how we feel. How, not what. The point is to note the concept, not the thought; the emotion, not the feeling.
The concept makes thought possible in the void. It presents us with the conditions of the possibility of knowledge, the experience of things as objects. We think we can know (or ignore) something here.
The emotion makes feeling necessary in the moment. It gives presence to the occasion of the necessity of power, the experience of people as subjects. We feel we must master (or serve) somebody now.
Writing maintains the language, the grammar of knowledge and power, the words for things and people, the joint between objects and subjects. Philosophy makes it clear; poetry keeps it tight.
