The plane of immanence is metaphysically consistent with
Spinoza’s single substance (
God or Nature) in the sense that immanence is not immanent
to substance but rather that immanence
is substance, that is, immanent to itself. Pure immanence therefore will have consequences not only for the validity of a philosophical reliance on transcendence, but simultaneously for
dualism and
idealism. Mind may no longer be conceived as a self-contained field, substantially differentiated from body (dualism), nor as the primary condition of unilateral subjective mediation of external objects or events (idealism). Thus, all
real distinctions (mind and body, God and matter, interiority and exteriority, etc.) are collapsed or flattened into an even consistency or plane, namely immanence itself, that is, immanence without opposition. The plane of immanence thus is often called a plane of consistency accordingly. As a geometric plane, it is in no way bound to a mental design but rather an abstract or virtual design; which for Deleuze, is the metaphysical or ontological itself: a formless, univocal, self-organizing process which always qualitatively differentiates from itself. So in
A Thousand Plateaus (with
Félix Guattari), a plane of immanence will eliminate problems of preeminent forms, transcendental subjects, original genesis and real structures: "Here, there are no longer any forms or developments of forms; nor are there subjects or the formation of subjects. There is no structure, any more than there is genesis." In this sense,
Hegel’s Spirit (Geist) which experiences a self-alienation and eventual reconciliation with itself via its own linear
dialectic through a material history becomes irreconcilable with pure immanence as it depends precisely on a pre-established form or order, namely Spirit itself. Rather, on the plane of immanence there are only complex networks of forces, particles, connections, relations, affects and becomings: "There are only relations of movement and rest, speed and slowness between unformed elements, or at least between elements that are relatively unformed, molecules, and particles of all kinds. There are only
haecceities, affects, subjectless individuations that constitute collective assemblages. ... We call this plane, which knows only longitudes and latitudes, speeds and haecceities, the plane of consistency or composition (as opposed to a plan(e) of organization or development)." == Pure immanence as lived philosophy ==
