Survival is likely a main theme. The mountain man in the novel probably has to deal with harsh natural elements, find food and shelter, which are all aspects of survival.
Another theme is mutual learning. In these stories, the mountain man and the city boy usually teach each other things. For example, the mountain man might teach the city boy about hunting or fishing, while the city boy might teach the mountain man about new technologies or modern fashion trends. This exchange of knowledge creates a bond between them.
The themes include the search for self - identity. The main character goes through different experiences in the magic mountain (the sanatorium), which makes him question who he really is. Also, the theme of social and cultural differences is present. People from different backgrounds gather in the sanatorium, and their interactions show different values and ways of life.
One of the main themes could be environmental collapse. The 'Dark Mountain' concept often delves into the idea of humanity's relationship with nature going awry, leading to a world in decline. Another theme might be the loss of hope or a sense of futility. It may show how in the face of overwhelming environmental and social problems, characters struggle to find meaning and purpose.
One main theme is love. The relationship between the main characters is a central aspect. Another theme is survival. The characters have to endure hardships during the war. Also, the idea of home and longing for a place of peace is important.
One of the main themes is love. The love between Ennis and Jack is complex and profound, yet they face many obstacles due to the social environment at that time which is not accepting of their relationship. Another theme is isolation. They are isolated not only because of their sexual orientation but also the nature of their work which often keeps them in remote areas. Also, the theme of loss runs through the novel. They lose the opportunity to be truly together and in the end, they lose each other in different ways.
The main theme could be perseverance. Manjhi's unwavering determination to cut through the mountain shows great perseverance.
Another theme is self - reliance. They are on their own most of the time. For example, in many stories, they make their own tools from scratch, whether it's a hunting knife or a fishing rod. They don't depend on others and rely on their own skills and knowledge. In 'The Resourceful Mountain Man', the protagonist uses his wits to fix his broken canoe without any outside help. He carves new parts from a nearby tree and uses vines as ropes. This shows how self - reliant mountain men are in these stories.
Another theme is adventure. They often went on long and dangerous journeys in search of furs, exploring uncharted territories. Their encounters with different Native American tribes also added to the adventure. These stories also often touch on themes of isolation and self - discovery. Living alone in the mountains for long periods made them face their inner selves.
Isolation is a prevalent theme. The mountain man is usually alone in the mountains, and the female character enters his isolated world. This isolation creates a unique space for their relationship to develop. It's a place where they can be away from the distractions and norms of society, allowing for a more intense and personal connection.
Since I don't know the exact mountain man story, it could have the mountain man himself as the main character. He would be the central figure around which the story revolves.
