I read a lot about people saying that it is impossible to be certain about anything with 100% certainty, but that means that this rule in and of itself must be true 100%.
I mean the rule that "we cannot be certain about anything" must itself be certain, which breaks the rule. So in order for this rule to be applied it needs to be broken at least once which is for itself.
This circular reasoning makes it hard for me to grasp.
Also some people divided the things that we can know for certain and the things we cannot (e.g functional certainty: I am certain I am writing this, not sure how, but certain it's happening), but even that has been doubted and counter arguments where proposed to refute it. So how exactly do we interpret this? Does it mean that this rule simply isn't all around true and that we can know somethings with absolute certainty?
100% doesn't mean a numerical representation that is mathematically practical, it just means "absolute"
