Purpose: The general objective of this study was to explore the nature of moral realism vs. anti-realism and its implications for moral discourse and practice. Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library. Findings: The findings reveal that there exists a contextual and methodological gap relating to the nature of moral realism vs. anti-realism and its implications for moral discourse and practice. Preliminary empirical review revealed that individuals' beliefs about moral realism vs. anti-realism significantly influenced their moral reasoning and behaviors, with proponents of moral realism exhibiting absolutist moral judgments while those endorsing anti-realism demonstrated greater moral flexibility. Cultural and ideological variations in these beliefs were evident, reflecting diverse societal norms and values. Longitudinal studies revealed the developmental origins of these beliefs, emphasizing the importance of early moral education. Overall, the study highlighted the complex interplay between philosophical perspectives on morality and real-world implications, advocating for informed and culturally sensitive approaches to moral discourse and practice. Unique Contribution to Theory, Practice and Policy: The Kohlberg's Stages of Moral Development, Social Identity theory and Cultural Relativism may be used to anchor future studies on the nature of moral realism vs. anti-realism. The study provided valuable recommendations for theory, practice, and policy. It contributed to theoretical advancements in moral philosophy by integrating empirical evidence with philosophical insights, thereby refining existing theories and generating new avenues for exploration. The findings had practical implications for educators, policymakers, and practitioners, emphasizing the importance of ethical education, interdisciplinary collaboration, and ethical leadership practices. Policy recommendations highlighted the need for contextually sensitive approaches to addressing ethical issues, while ethical practice emphasized fostering open dialogue and ethical reflexivity in professional settings. The study also identified future research directions, suggesting the importance of longitudinal and interdisciplinary studies to further advance our understanding of morality and ethics.
