This chapter embarks on a journey through the essential principles of existentialism and how they can be effectively integrated into the English language and literature classroom, especially in India. It defines and elaborates upon core existentialist concepts, such as freedom, choice, absurdity, and authenticity against the backdrop of postcolonial thought. By comprehending their philosophical underpinnings, teachers can better appreciate how these concepts can be applied to texts and discussions within the classroom. Thus, this chapter serves as a foundational exploration of critical concepts within existential humanities, offering practical insights, examples, and pedagogical strategies for educators.
