African Philosophy has a rich history in Madagascar, where it plays a significant role in shaping ethical debates and cultural practices. The study employs qualitative analysis of historical texts, contemporary literature, and interviews with philosophers and cultural practitioners from Madagascar and other regions. Comparative methodologies are used to highlight similarities and differences between African philosophies and global ethical frameworks. A notable theme in the findings is the integration of traditional Malagasy concepts like fady (taboos) into modern discussions on environmental ethics, reflecting a continuity with ancient philosophical thought. This study underscores the importance of cross-cultural dialogue in understanding and addressing contemporary ethical challenges. Future research should focus on empirical studies to validate findings and explore how African philosophies can be more actively engaged in global ethical debates.
