In some important ways, the systems have become more independent from one another under modernity, during the last 200 years or so. As Weber’s classical sociology established, the genius of modernity, the spirit of modern society, is its ability to tease out different dimensions of social reality from one another: 1. the rational/scientific objective truth, 2. the subjective/personal aesthetic, and 3. the interpersonal/moral realm. You can’t burn someone at the stake for making a scientific claim anymore.
