Poetry is the most precise means we have at our disposal to engage with culture. Philosophy offers comparable precision in dealing with nature.
I'm tempted to say your culture, your nature. That is, a poem will never occasion a confrontation with culture "as such", and there is of course no such thing. There's only ever whatever culture you carry within you. Likewise, philosophy can show you nature as it inheres in you, not as "it is" separate from your experience of it.
The locus of our philosophical encounter with nature is the concept, which is simply the attunement of our perceptual apparatus to particular things, thus rendered immediately knowable in experience as objects. The temper of our poetic encounter with culture, meanwhile, is the emotion, i.e., the direction of our actual dispositions among particular people, thus immediately empowering us as subjects.
It is by putting these encounters into words, clearly in the case of philosophy, intensely in the case of poetry, that we attain the highest available precision in our engagements with nature and culture.
Language strives towards precision. It articulates us.
