存在的個體性 (Haecceity)

Deleuze uses the term to denote entities that exist on the plane of immanence.

Plane of immanence (French: plan d'immanence) is a founding concept in the metaphysics or ontology of French philosopher Gilles Deleuze. Immanence, meaning "existing or remaining within" generally offers a relative opposition to transcendence, that which is beyond or outside. Deleuze rejects the idea that life and creation are opposed to death and non-creation. He instead conceives of a plane of immanence that already includes life and death. "Deleuze refuses to see deviations, redundancies, destructions, cruelties or contingency as accidents that befall or lie outside life; life and death were aspects of desire or the plane of immanence." This plane is a pure immanence, an unqualified immersion or embeddedness, an immanence which denies transcendence as a real distinction, Cartesian or otherwise. Pure immanence is thus often referred to as a pure plane, an infinite field or smooth space without substantial or constitutive division. In his final essay entitled Immanence: A Life, Deleuze writes: "It is only when immanence is no longer immanence to anything other than itself that we can speak of a plane of immanence."
