Answer:
Two themes to be explored could be madness/doom and survival.
Explanation:
Madness: when the line separating reality from imagination is blurred, people begin to act strangely, madly, and loose the ability to cope with feelings of anxiety or desperation in a coherent, healthy way.
- Why will this situation be developed? The situation of the four stranded seamen is condemned to become cahotic if their circumstances remained unchanged. The captain is already showing signs of desperation and paranoia in the form of a "stern impression of a scene in the grays of dawn...".
Survival: when people find themselves in life or death situations, a number of psycological mechanisms begin to activate to ensure survival: among them an increased sense of competitiveness. Also, people tend to become more resourceful to maximize the odds of preserving life, yet they also turn more viscious and territorial.
- Why will this situation be developed? The story is about four men stranded at sea, and though we lack information regarding their specific circumstances (food, supplies, tools), it is clear that their lives are at stake. The laws that rule society apply differently when the only concern is to remain alive and the circumstances are extreme.
