There have been long debates over the definition of human freedom. This issue touches on both man's freedom from social and political restrictions as well as his inherent potential for free will and activity in nature. In order to analyze the nature of freedom in relation to country-building, this paper identifies a lack of freedom as a key impediment to nation formation. Additionally, it assesses human freedom and nation-building issues from an existentialist angle. The fundamental ideas of existentialism are that truth must begin with subjectivity, that existence comes before essence, that reality is in action, that life is meaningless, and that man can only give his existence meaning by acting. This paper makes an effort to demonstrate how philosophy is important for the advancement of society and the nation. According to the argument made in this paper, the desire for freedom serves as the foundation for all progress. Every person has the fundamental right to freedom, which includes the capacity to choose how to live one's life and how the country will evolve in the future. In this perspective, development is the capacity to free humans from the potentially harmful influence and power of the ecological, geophysical, and global environment. It is impossible to borrow and must not be denied that this capacity exists. Natural development must be supported, encouraged, and enhanced. It concludes that to establish uniqueness and genuine nationalism, Citizens must work to achieve freedom and self-determination.
