Edges 

Certain ideas are axiomatic to navigating and defining existence. As necessary markers they are generally considered to be unproblematic in their everyday use and understanding. This is rightly so, because any unbridled and ceaseless challenge to their obvious necessity would result in a constantly stalled experience of existence. One other such experiential necessity, and perhaps even the most important one at the level of the everyday, is that of the Edge. All concepts of difference, from the ethereal to the material, from the ideal to the empirical, from words to things, from desires to actions, from past to present to future, demand some form of border in order to differentiate each from each, this from that.
