Explanation & Answer:
1)Later, Aylmer pours liquid over a diseased plant before having Georgiana drinks the liquid. The liquid removes the plant's discolorations, just as it removes Georgiana's birthmark.
2)Aminadab symbolizes man's earthly, physical half; Aylmer symbolizes man's lofty, spiritual half. Our second tip-off is his name.
3)Aylmer reasons that the birthmark is Nature's way of showing Georgiana's mortality and necessary humanity. He wants to remove the mark, then, not because he doesn't like the way she looks, but because of what the symbol represents to him (see "Symbols, Imagery, Allegory").
4)Man vs Society is when Alymer says that her "birthmark" is an "Earthly imperfection" and he wants to remove it. He wants her to be perfect. Everyone else Georgiana encounters says it is a charm. Alymer is against society because he says it looks like an imperfection but everyone else says it looks beautiful.
