bodiesin

bodiesin is a neologism used in discussions of embodiment, systems theory, and multi-body dynamics to refer to the relationship in which discrete physical bodies are contained within or incorporated into a larger system. The term is not tied to a single discipline and has appeared in philosophy of cognitive science, human–computer interaction, and engineering literature as a descriptive shorthand for containment, incorporation, or functional nesting of bodies within structures.

In philosophy of mind and phenomenology, bodiesin is used to discuss how the sense of bodily boundaries changes with tool use and environmental embedding, highlighting the permeability of the boundary between self and world. In robotics and biomechanics, it denotes modeling approaches where components such as limbs, tools, or prostheses are treated as sub-bodies inside a main chassis, enabling modular analysis of kinematics and constraints.

In practice, bodiesin emphasizes relational rather than intrinsic properties of bodies and supports system-level reasoning about constraints, control, and adaptation. Critics argue the term can be vague and redundant with existing notions such as embedding, embodiment, and containment.
