👉 A boundary fluid refers to the transitional space or area that separates distinct concepts, categories, or domains within a larger framework. It delineates the limits of understanding or categorization, often marking where one perspective or field ends and another begins. These boundaries are not always rigid; they can be porous, allowing for overlap or interaction between adjacent concepts. Boundary fluids are crucial in fields like philosophy, linguistics, and cognitive science, as they help define the limits of thought, language, and knowledge, facilitating deeper insights into how we structure and navigate our understanding of the world.
