Regarding the Merchant:

I perceive a linear formation DAE, where the midpoint (A) is luminously pronounced due to its proximity. However, the brightness diminishes swiftly on either side, as AC and AB recede into the fog. Consequently, the ends, D and E, gradually fade into deep obscurity.

Turning to the Physician:

For the Physician, although I also discern a line (D'A'E') with a brightly illuminated center (A'), the rate of descent into dimness is less abrupt. The sides A'C' and A'B' recede more slowly into the fog, resulting in D' and E' not being as dim as those of the Merchant.

The discerning Reader will glean from these examples how, through extensive training and continuous experience, the cultivated among us can differentiate with relative precision between middle and lower classes based on visual cues. If my esteemed Spaceland audience has grasped this overarching idea, recognizing the feasibility of such discernment, I shall consider my goals achieved. Additional details might only sow confusion. Nonetheless, for the youthful and inexperienced who might deduce from the two simple examples—how I identify my Father and my Sons—that the act of sight recognition is effortless, a clarification is warranted. In truth, the real-life challenges of visual identification are often far more intricate and multifaceted.
