Rhizome

Definition

Jeff Vail:

"Rhizome takes it name from plants such as bamboo, aspen, or ginger that spread via a connected underground root system. As metaphor, Gilles Deleuze and Felix Guattari used rhizome to refer to a non-hierarchal form of organization. I have extended this metaphor, refering to rhizome as an alternative mode of human organization consisting of a network of minimally self-sufficient nodes that leverage non-hierarchal coordination of economic activity. The two keys concepts in my formulation of rhizome are 1) minimal self-sufficiency, which eliminates the dependencies that accrete hierarchy, and 2) loose and dynamic networking that uses the "small worlds" theory of network information processing to allow rhizome to overcome information processing burdens that normally overburden hierarchies."

Description

From the Wikipedia:

"In philosophy, the term rhizome has been used by Carl Jung as a metaphor, and by Gilles Deleuze as a concept, and refers to the botanical rhizome.

Gilles Deleuze and Félix Guattari used the term "rhizome" to describe theory and research that allows for multiple, non-hierarchical entry and exit points in data representation and interpretation. In A Thousand Plateaus, they opposed it to an arborescent conception of knowledge, which worked with dualist categories and binary choices. A rhizome works with horizontal and trans-species connections, while an arborescent model works with vertical and linear connections. Their use of the "orchid and the wasp" was taken from the biological concept of mutualism, in which two different species interact together to form a multiplicity (i.e. a unity that is multiple in itself). Horizontal gene transfer would also be a good illustration.

Rhizome theory is also gaining currency in the educational field, as a means of framing knowledge creation and validation in the online era. In 'Innovate - Journal of Online Education, Vol. 4, Issue 5', Dave Cormier critiques the limitations of the expert-centered pedagogical planning and publishing cycle, and posits instead a rhizomatic model of learning. In this rhizomatic model, knowledge is negotiated, and the learning experience is a social as well as a personal knowledge creation process with mutable goals and constantly negotiated premises. The rhizome metaphor, which represents a critical leap in coping with the loss of a canon against which to compare, judge, and value knowledge, may be particularly apt as a model for disciplines on the bleeding edge where the canon is fluid and knowledge is a moving target."
