The old art/life distinction.
The "triangulation" theory of David Robbins.
This notion is worked out in various ways throughout his book The Velvet Grind, but the essay "On Talent" spells things out pretty directly:
That something might stand outside art and report on it, comment on it, editorialize about it in an iconic language of its own - this was, and apparently still is, disorienting. The reason, I submit, is that it instantiates a complication of the modernist dialogue between life and art. Talent suggests that the old binary model has been superseded by a triangulated model whose points are life, art, and entertainment - a competing communication system no less madly self-sustaining, self-referential, and self-celebratory than art. "Showbiz" adds another category that's neither Art nor Life. pg.24
Robbins's triangulation is an important step to finding new forms and languages for what he calls "imaginative practice" - creative, funny, thoughtful forms of invention that are not art. We at LesiureArts find Robbins incredibly useful [We hope to write more, but being the slackers that we are, this might be as far as we get]. He also writes about inventing experience which he distinguishes from producing culture. This is a welcome relief from all of the talk about cultural production, as invented experience resonates nicely with John Dewey's aesthetic theory which is in dire need of being read by the legions of curators and artists who are reinventing the wheel of experience based practices.
The LeisureArts modified model.
As we mentioned, the triangulation theory is an important step, but LeisureArts is interested in expanding the terrain of inventive practices and theory to cover a host of other activities that Robbins's triangle can't account for. That leads to the above modification. In leisure, we have a broad field of activities that fall in between the various oppositions, some closer to one vertex or the other, but the field itself exists in a kind of equipoise (ideally). Adding leisure to the model allows for the inventiveness of car customizers, tea cozy makers, coat hanger collectors, home cooks, and others to mingle on equal footing with so called "high" forms of culture be it entertainment or art.
