Everything is interaction and reciprocal

“Everything is interaction and reciprocal” names a vision of nature as a living web rather than a collection of separate things. Attributed to Alexander von Humboldt, the phrase connects the mutual activity of species to the narrator’s later experience of feeling part of the natural world he had once observed from a distance.

Humboldt’s relational vision

Humboldt’s formulation belongs to a way of seeing nature that treats its inhabitants as subjects acting upon one another, not as discrete objects arranged for human observation. The book associates this vision with Romantic science and with cultivating the plant’s-eye, animal’s-eye, microbe’s-eye, and fungus’s-eye perspectives. Such imaginative shifts make visible a densely entangled world of reciprocal relations and coevolution.

The contrast is with the increasingly specialized science that moved observation indoors and relied on instruments to reveal scales beyond ordinary human sight. Those methods brought practical power, but the narrator argues that they also helped turn nature into an object of study. The Humboldtian phrase holds open another perspective: one attentive to what living beings do to and for one another, and to the material and spiritual costs of treating the rest of nature as merely other.

Reciprocity beneath the forest

The phrase is linked to Paul Stamets’s effort to discern systems operating beneath the forest floor. His metaphors for the underground fungal network—the earth’s Internet, nature’s neurological network, and the forest’s immune system—express an ecological imagination in which connection is not an ornament but a way to understand how living systems work.

A concrete example is Stamets’s account of Honey bees visiting woodpiles. The narrator describes them as nibbling on a saprophytic mycelium that produces an antimicrobial compound useful to the hive. In this proposed exchange, the fungus supplies something the bees need, while what it receives in return remains an open question. The example makes reciprocity tangible without pretending that every part of the exchange is understood: relations can be consequential even when their terms are not yet fully known.

From proposition to experience

The phrase takes on a personal force during the narrator’s psilocybin experience with Judith. On a garden path at dusk, the narrator sees numerous dragonflies crossing the flowers; Judith later confirms that they were there. The garden’s familiar evening activity no longer appears as scenery viewed by an outside observer. Instead, the narrator feels deeply implicated in it, one being among many and in relation to the whole. The passage culminates in the remembered words, “Everything is interaction and reciprocal,” followed by the narrator’s sense that “I myself am identical with nature.”

The book does not settle on a single explanation for this shift. The narrator is unsure what to make of the experience, but describes feeling the personhood of other beings and a temporary loosening of whatever usually prevents a sense of full implication in nature. An opening of the heart toward parents and Judith extended, unexpectedly, to plants, trees, birds, and insects; some of that openness persisted afterward. The Humboldtian phrase thus moves from an account of ecological interdependence to a lived perception of belonging, while leaving the experience’s spiritual meaning unresolved.
