The purpose of this study is to investigate how authentic living affects personal development, ethical decision-making, and societal participation, aligning theoretical insights with practical applications. The study was motivated by the need to understand how neglect of existential responsibility leads to inauthentic behaviors such as conformity, avoidance, and moral compromise in education and society. Data collection involved analysis of philosophical texts, secondary literature, and synthesis of theoretical tables summarizing personal, psychological, ethical, and societal implications.
The findings show that authenticity improves self-awareness, deliberate decision-making, ethical responsibility, and social engagement. Furthermore, inauthenticity correlates with conformity, avoidance, and superficial engagement. The study concludes that embracing Heideggerian authenticity enhances personal, ethical, and societal outcomes. Authentic engagement equips individuals with reflective thinking, responsible choice, and moral awareness, while inauthenticity undermines these capacities. Based on the findings, it was recommended that individuals should actively engage in self-reflection and deliberate decision-making to cultivate authentic living. Also, educational institutions should incorporate programs and curricula that encourage students to explore their values, confront existential realities, and develop critical thinking skills.
