Resumen:
Industry 4.0, which is at the core of the Fourth Industrial Revolution, posits the challenge of humanizing it. Drawing upon Catholic Social Teaching (CST), this article offers a set of ethical and spiritual criteria for such humanization. The starting point is a positive attitude of CST toward technology, admiring it not only for its usefulness, but also as an expression of human creativity, ingenuity, and beauty. This entails a transcendent sense leading to praise the Creator. At the same time, CST warns that technology involves the risk of fostering a techno-centered worldview and calls for a humanistic-centered worldview. Other ethical criteria regard conducting technological developments with ethical guidelines, minimizing inside effects of technological implementations, managing technology for the com-mon good, and introducing technology into the production process in respect of human dignity and favoring human flourishing.
