Critical thinking Section

a. How does the author make satire on the modern idea of the ‘self’ based on individuality, independence and uniqueness?

In this essay, the author satirizes the modern concept of'self,' which is based on individuality, independence, and uniqueness. This essay is about the self and what nature can teach us about ourselves. In the beginning, the author draws attention to the human trend of enhancing the sense of self through individuality, independence, and uniqueness.

 

The author describes the close relationship between a nudibranch and a medusa in the Bay of Naples. A full-grown jellyfish eats a tiny snail that just hatched, but the snail eats it bit by bit until the jellyfish is just a round "successfully edited parasite" stuck to the snail's skin near its mouth. Finally, the tentacles, until the jellyfish is eaten and its substance is reduced, while the snail grows in size. This essay demonstrates that both creatures cannot live without the other; they rely on each other for survival.

 

The author tells the story of the nudibranch and the medusa to show how important it is to get along, help each other, work together, and be together. We are all important, and one's life is determined by another, just as the relationship between anemones and crabs and medusa and snail is. It also emphasizes the importance of friendship and our reliance on one another for survival and existence. The author justifies this by stating that modern people's pride in the concept of individuality, independence, and uniqueness is not applicable in real and practical life.

Writing Section

A. Write an essay on "Independence vs. Interdependence" in about 250 words.

Independence vs. Interdependence

For a long time, the concept of independence versus interdependence has been a source of contention. Some people believe that independence is necessary for personal growth and success, while others believe that interdependence is required for societal growth and progress. Both independence and interdependence have advantages and disadvantages, and finding a balance between the two is critical.

 

The ability to think and act freely without being influenced by others is referred to as independence. It entails being self-sufficient and not relying on others for one's success or happiness. Independence is frequently regarded as a positive characteristic because it fosters self-confidence, resilience, and the ability to take risks. It can, however, lead to isolation, arrogance, and an inability to collaborate effectively with others. Interdependence, on the other hand, refers to the ability to collaborate and work well with others. It entails accepting that one's success is inextricably linked to the success of others and that no one can achieve success on their own.

 

Interdependence is often seen as a good trait because it encourages teamwork, cooperation, and a sense of belonging. It can, however, lead to reliance on others, a lack of personal responsibility, and a fear of taking risks. In reality, both independence and interdependence are important in different situations. Independence is essential for personal development, but interdependence is required for social and cultural development. In today's interconnected world, it is clear that both independence and interdependence are required for success and progress. Individual needs must be balanced with the needs of the larger community.

 

Finally, independence and interdependence are two critical concepts that must be grasped and balanced. Neither is inherently good or bad, but they both have benefits and drawbacks. People must learn to be self-sufficient while also appreciating the value of collaboration and community. We can only achieve true success and progress by balancing these two concepts.

 

B. Write a newspaper article highlighting the increasing individualism in modern Nepali society.

Individualism on the Rise: A Concern for Nepali Society

Individualism is the idea that people should be free and responsible for themselves. It is becoming more and more common in Nepali society. The traditional values of collectivism, community and family are being replaced by a new focus on individual achievement, personal freedom, and independence. While individualism has its advantages, this trend raises concerns about its long-term effects on society.

 

One of the primary drivers of individualism in Nepal is globalization. The influence of Western culture has led to the adoption of individualistic values, such as prioritizing individual needs over those of the community or family. As a result, the social fabric of Nepali society is changing, and the traditional support networks that have sustained communities for generations are weakening.

 

This shift towards individualism is reflected in various aspects of Nepali life. Young people, in particular, are pursuing higher education and career opportunities, often at the expense of family and community ties. Social media platforms are increasingly used to promote individualism, with people showcasing their achievements and lifestyles for personal validation.

 

While there are benefits to individualism, such as personal freedom and self-expression, it can also lead to social isolation and the breakdown of communal support systems. Nepali society is in danger of losing its unique cultural identity and becoming more individualistic, disconnected, and self-centered.

 

Because of this, it is important for Nepali society to find a good balance between individualism and collectivism. It is important to keep traditional values and social structures in place while also being open to change and new ideas. By doing this, we can make a society where people are both independent and dependent on each other, where each person can do well and also help the community as a whole.
