The text critically examines the modern conception of the relationship between knowledge and power, as primarily articulated by Francis Bacon and Thomas Hobbes. The author argues that reducing knowledge to a mere instrument for power or the execution of plans is a profound philosophical error. This critique is structured around three key points: first, knowledge possesses intrinsic value, and humans seek it for its own sake; second, much knowledge pertains to unchangeable realities that must be acknowledged regardless of our utility; and third, the most crucial dimension is ethical knowledge—understanding what we ought or ought not to do. The text warns against an instrumentalized view of science that neglects the moral purposes and limits of human action. It poses the fundamental question of whether we are permitted to do everything that our technical knowledge makes possible. Ultimately, the reflection calls for a return to a broader understanding of knowledge that encompasses responsibility and wisdom beyond mere efficiency.
