Final answer:
The stranger's physical and mental state in Frankenstein reveals a theme of isolation and alienation.
Step-by-step explanation:
In Mary Shelley's novel Frankenstein, the stranger's physical and mental state reveals a potential theme of isolation and alienation. The monster, being created by Victor Frankenstein, is rejected by society and suffers from loneliness and a lack of acceptance. This theme is evident in the stranger's appearance, as he is described as hideous and monstrous, which further contributes to his isolation from others.
