Although this is a simplification, and I will not here explain the structure or neurology of the visual sense, we might apply a model [of mind] where, essentially, there is a peripheral system and a central or foveal system. The peripheral system excels at certain tasks, such as seeing in dim light, or detecting subtle visual anomalies. It is extremely useful at night and in dealing with predators; the latter because it probably requires significantly less processing — it is directly linked to fast-processing structures in the interhemispheric fissure — between the two hemispheres. It can be practiced, as both martial artists and jugglers are at least peripherally aware. It is here, however, that we begin to encounter something more interesting about these aspects of our visual system: one prefers anonymity. In fact, when I say peripherally aware, what I largely mean is this: subconsciously.
