Fellow atheists: How do you know your senses and reasoning are reliable and valid? How do you know that you know anything? Solipsism vs Nihilism

Just looking for other answers to this.

How do you know that you know anything? How do you know you can rely on your senses? (As in: I know the rock exists because I can see the rock. How do you know you can see it?)

If knowledge is reliant upon our senses and reasoning (which it is), and we can't know for sure that our senses are reasoning are valid, then how can we know anything?

So is all knowledge based on faith?

If all knowledge is based on faith, then is science reliable?

If all knowledge is based on faith, then what about ACTUAL faith? Why is it so illogical?

Solipsism vs Nihilism

Solipsism claims that we know our own mind exists, where Nihilism claims we don't know that anything exists.

Your thoughts?

  • is all knowledge based on faith

    It's based on assumption, not faith. If we can trust our senses, and if things will continue to be as they have been, then the things we are learning have value. As long as you can recognize that everything could in theory end or completely change at any moment, it's not blind belief.
