PhronesisWe apply the displacement framework to grief and bereavement. The central thesis is that grief is displacement without a pre-existing return path. The lost person, place, or state was a structural component of the organism's ground state S^0; death or loss permanently removes that attractor, leaving the system displaced with no direct path home. The five stages of grief identified by K\"ubler-Ross are reinterpreted not as a fixed emotional sequence but as distinct displacement dynamics, each representing a different strategy for engaging with the gap D(_grief) = \|s_current - S^0_with\| > 0.
Prolonged grief disorder (PGD) is formalized as entrapment in a wrong attractor: the system oscillates around the loss without ever constructing the new ground state S^0_new that would allow stabilization. Healthy grief is the mandatory, effortful work of building S^0_new when the old one has been permanently removed. We treat collective grief, memorialization, and mourning rituals as return-path infrastructure — socially constructed scaffolding for a path that cannot exist at the individual level alone.
Post-traumatic growth is interpreted as S^0_new formed at higher dimensionality than S^0_with.
