The growing dominance of modern technology in human life raises philosophical questions concerning the relationship between knowledge, being, and will. Although Heidegger offers an ontological critique of technology, the questions of metaphysical grounding and finality in his thought warrant further critical examination. This study aims to analyze Martin Heidegger’s epistemological position on technology through the interrelationship between knowing, being, and willing, and to evaluate it from the perspective of Thomas Aquinas’s epistemology and metaphysics. Employing a qualitative approach, this study uses library research and comparative philosophical analysis of Heidegger’s major works on technology and Aquinas’s metaphysical thought. The findings indicate that Heidegger understands technology as a mode of revealing reality that reduces nature to Bestand, or standing-reserve. Through Gelassenheit (releasement) and meditative thinking, Heidegger proposes an alternative attitude toward technological domination. However, his approach leaves unresolved questions concerning ontological grounding and finality. This study concludes that Heidegger’s critique of technology raises the need for a grounding of being that remains insufficiently articulated within his philosophical framework. Aquinas’s concepts of intrinsic and extrinsic finality provide an alternative metaphysical foundation for understanding the relationship between humanity, nature, and technology. The study contributes a critical interpretation of Heidegger’s philosophy of technology through Thomistic finalistic realism, thereby enriching discussions on the epistemology and ontology of technology while offering a reflective framework for evaluating the purposes of modern technological practices.
