Under most circumstances, don't we ordinarily say, "I know Paris is the capital of France?" Of if we actually say, "I believe Paris is the capital of France," this is a polite way of making the statement, of saying the same thing?
I am merely suggesting that there is a major difference between "belief" and "knowing" that something is the case. We can, for example, understand the rules for determining whether a matter of fact is true or false by appealing to them, but cannot in matters of belief.
Nor do we ask for a show of hands about whether Paris is the capital. What would happen, for example, if we asked our question in a village in the Amazon, and the natives by show of hands thought that Paris was some kind of animal?
Not that long ago, a majority of educated people believed the world was flat; was it flat then and later actually round, or was it a sphere all along and people were mistaken
Consider this: is something true because "everyone" agrees that it is so, or does "everyone" agree something is true because it is true.
