In this discussion of Preston's article, “The Edge of Awareness,” I share my reactions and pose some questions. I will not try to answer them. The central theme of the article relates to a sense of process that is often referred to by clinicians, but seldom clearly defined. When we speak about a sense of process, are we talking about pushing the edge of awareness? Can we define this sense more clearly, or is it itself often on the edge of awareness? In essence, is this sense of process an implicit walking of the boundary between knowing and not knowing? The discussion closes with a brief illustration of a “sustained empathic focus.” Even in the abstracted form presented here, I think that it is a good example of one of the many ways that analysts intuitively encourage the exploration of Preston's concept of the “edge of awareness.”
