Division & Boundary is a film-based inquiry into the semantics of soil, probing how language and scale structure our understanding of the ground beneath us. What differentiates dirt from soil, or ground from land? Do size, context, or granularity govern these categories? Drawing on object-oriented ontology, folk taxonomy, and linguistic notation, this short film explores how classification systems shape perception, without requiring universal agreement to carry weight. Not everyone agrees on the boundary of a category, not everyone uses the same terms to mark the division, but we negotiate meaning all the same. The asterisks marking certain terms in the typology is borrowed from linguistic convention, denoting semantic discomfort when referent and label misalign. A clump of earth on a field may be “land” in situ, but once removed, it becomes “dirt.” When smeared on paper, that same substance becomes the causation of the paper becoming “dirty” (and never “landy”). These shifts in linguistic framing reflect deeper cultural and cognitive negotiations in how we understand place. The implications stretch far beyond grammar. Landscape ontology underpins land use policy, heritage claims, geographic naming, mineral rights, legal disputes, and national borders. It touches tourism, memory, identity, and the entire infrastructure of mapping. This film registers those tensions and categorical ambiguities as signals and evidence of how language and land remain in a state of ongoing negotiation.
