As visual thinkers, we often resort to the impromptu diagram to help bring us through a conceptual morass. Through the years, we have taken this conceit one step further in our belief that our nascent theories and philosophies should lend themselves to a visual form. While not a universal dictum, it is more a litmus test, not of the idea per se, but of its application.
The act of diagramming often helps clarify holes in our thinking which is not always a bad thing. For every hole we have discovered and patched up there has been another into which we have jumped; often blindfolded and woefully unprepared, these gaps are gateways to our most cherished projects.
