Of course, the paucity of my recollection should come as no surprise, as the mind's eye is limited in terms of the visual impressions it can conjure from childhood. However, mental images of relatively poor quality are typical not just of early childhood memories, but usually memories in general. As evidence of the relatively weak powers of visual memory, one need only compare its faded stores, faintly traced in the mind's eye by withering neural pathways, to the limpidness of perception in the here and now.
While the clarity of perception stands in contrast to the haziness of visual memory, under certain circumstances, there is something of a subjective fusion between the realms of remembering and perceiving, and the two psychological domains, normally so distinct to us, are bridged by a point of contact provided by sensory impressions. A common example of this can be found when looking at your reflection in the water; the image, usually soft and blurred, is not a faded memory trace, but an immediate sensory impression gathered by your eyes. And yet, the reflection seems to resemble not a perception, but a memory, with many of the hazy impressions that characterize the mind's attempt to travel backwards in the 4th dimension.
I imagine, however, that for many of the American and British soldiers, scouting the banks of the river on a hot day in September of 1777, seeing their reflection in the water produced a deeper experience. They were, no doubt, acutely aware of their own mortality, and I wonder how many of them, when they stopped along the banks of the Brandywine for a drink, paused when they saw their dull image in the glassy surface of the water. They must have wondered if they would soon cross a threshold from the realm of the living to that of the remembered, where all of us will reside one day as faded sketches, until these too are washed away by the inexorable river of time.
