Is there any fundamental difference between an individual's beliefs (say, religious belief) and empirical knowledge (say, scientific knowledge)? The former is clearly based on faith: the individual believes that e.g. God exists because he believes what his religious texts, his parents, his teachers, his peers, the media he chooses to consume say. But is that not the same in the latter case? The individual believes that Earth is round as opposed to flat, not because he has actually seen Earth from above or performed any other relevant experiments, but simply because he believes the textbooks, his parents, his teachers, his peers, and the media. The average individual's "knowledge" that the Earth is round is based entirely on hearsay. The same holds true for many other "facts" (even non-empirical, a priori ones). In this light, isn't our level of assuredness in these facts rather irrational and quasi-religious?
