Abstract

Dialogue is treated in this paper as a fundamental aspect of human nature that enables individuals to express themselves, seek truth, and build universal civilisation. This study explores the role of dialogue as a manifestation of human rationality and its implications for social harmony. Utilising a multidisciplinary approach, this research integrates philosophy, psychology, and social theory perspectives to analyse how dialogue shapes individual identity and collective understanding. The findings reveal that dialogue fosters cooperation, reduces prejudice, and enhances trust between groups but is often hindered by polarisation, fanaticism, and misinformation in the digital era. This paper argues that effective dialogue requires individual communication skills and social structures that promote inclusivity and rationality. This study contributes to the discourse on building a more inclusive and just civilisation through meaningful communication by addressing these challenges.
