If you are interested in this topic, I really cannot recommend reading A Secular Age by the philosopher Charles Taylor enough. It’s a huge book but the basic takeaway is this: the modern secular world is a thing that was created over the course of many centuries and cultural developments. It is not merely the subtraction of so-called primitive beliefs. The “subtraction thesis” is the predominant model of how most people (and until recently, religious scholars) interpreted the secularizarion process. This means that the same basic historical and psychological forces are at play, but they’ve just been morphed and combined in different ways. What is truly new about the modern secular world is its immanence, which basically just means it is not concerned with a “world beyond” this one, and its “cross pressures”, or the state of being aware of other viable alternatives to one’s belief system. https://en.m.wikipedia.org/wiki/A_Secular_Age https://en.m.wikipedia.org/wiki/A_Secular_Age
