● jingle · one word, three constructs Nearest construct by meaningphasecompare the meaningsEvery construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to coexistence is phase.
Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

In metaphysics, coexistence is the relation between two or more things that exist at the same time. Leibniz, in his 1715 to 1716 correspondence with Samuel Clarke, defined space itself as the order of things that coexist, so that simultaneous existence becomes the basic relation from which spatial order is built. Kant, in his 1781 Critique of Pure Reason, treated coexistence in the Third Analogy of Experience as requiring that coexisting substances stand in thoroughgoing reciprocal interaction, so that they can be known to exist together. The referent is a temporal and metaphysical relation of existing together in time, not phases sharing a container, populations sharing a habitat, or states sharing an uneasy peace.[1][2]
In thermodynamics, phase coexistence is the state in which two or more distinct phases of a substance, such as liquid water and its vapour, are present together in stable equilibrium. Gibbs, in On the Equilibrium of Heterogeneous Substances (1876 to 1878), gave this its exact treatment: he derived the conditions under which phases coexist and the phase rule relating the number of coexisting phases to the number of components and the free variables of the system. The referent is a physical equilibrium between forms of matter at a shared temperature and pressure, counted by how many phases are present at once, and it has nothing to do with things being simultaneous in time, species living together, or nations at peace.[3]
In ecology, species coexistence is the lasting persistence of two or more species together in the same place, rather than one competitor driving the others to local extinction. Volterra, in his 1926 Fluctuations in the Abundance of a Species Considered Mathematically, modelled when competing populations settle into shared persistence, and Gause's 1934 The Struggle for Existence tested this and held that species with identical requirements cannot persist together. Chesson's 2000 review Mechanisms of Maintenance of Species Diversity set out the modern account of what keeps coexistence stable. The referent is a population outcome tracked across a community over time, and it is separate from phases at equilibrium, things being simultaneous in time, or a political truce.[4][5][6]
