A rhizomatic system is comprised of a multiplicity of lines and connections. "There are no points or positions in a rhizome, such as those found in a structure, tree, or root. There are only lines."
A rhizome is a concept in post-structuralism describing a nonlinear network. It appears in the work of French theorists Deleuze and Guattari, who used the term in their book A Thousand Plateaus to refer to networks that establish "connections between semiotic chains, organizations of power, and circumstances relative to the arts, sciences and social struggles" with no apparent order or coherency
The word [rhizome] is associated with postmodern theorists Gilles Deleuze and Felix Guattari, who use the rhizome to describe a process of existence and growth that does not come from a single central point of origin... arborescence or the model of the tree as the paradigm for knowledge and practice in the modern Western world; in this model, a small idea—a seed or acorn—takes root and grows into a tree with a sturdy trunk supporting numerous branches, all linked to and traceable back to the original seed. They offer instead the rhizome or fungus, which is an organism of interconnected living fibers that has no central point, no origin, and no particular form or unity or structure. A rhizome does not start from anywhere or end anywhere; it grows from everywhere, and is the same at any point.
The rhizome is a-linear, multiple, spread out, all proliferating and without boundaries centres/margins or limits. This is what Deleuze terms a “horizontality” of thought. Rejecting the “Father Principle” or the principle of the origin-as-identity, Deleuze and Guattari argue that there is no distinction between the individual and the collective.
