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 (lemmy.ml)

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?

How do we know the world isn't a simulation created by an omnipotent trickster? How do we know that all memories aren't implants and we're all exactly 30 seconds old?

It takes no faith to accept your perceptions as reality, because what is the difference? If there is evidence that anything is wrong with our senses, then observations will not be internally consistent. If that is the case, then such inconsistencies will be discovered and revealed. But any trickster or simulation capable of perfectly recreating reality is functionally identical to reality.
