Abstract: Starting from Heidegger’s critique of modern science, it becomes apparent that the foundation of the critique of science is rooted in the critique of metaphysics, and its source lies in a critical reflection on factical life. Taking this as a starting point, we can delve into Heidegger’s redefinition of the relationship between science and technology: technology is not merely the application of science, but constitutes the essence of science itself. The underlying reason for this lies in the fact that technology, as a fundamental characteristic of Western metaphysics, is most directly related to life experience, while at the same time taking a crucial step from life to theory (abandoning life). Therefore, regardless of how science and technology evolve, the essence of technology remains unchanged. The proper human attitude toward technology is neither optimistic nor pessimistic, but a dual attitude that both affirms and negates.
