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?

    Does it matter? Endlessly pontificating about the true nature of reality serves no purpose. If I’m driving and I’m about to hit a tree, reality doesn’t give a single fuck if I consider “well maybe the tree isn’t really there. How can I truly know?”

    Like, I was talking with a guy and he was saying shit about how can we truly know that what I say is the color green is the same as what you see? It just feels mastubatory. It’s what words are for. If that guy asks me to go to the store and buy forest green paint from a certain brand and I come back with forest green paint from that brand he’s not going to worry about whether or not we see the exact same shade.

    I have no absolute knowledge, but I have lots of probabalistic knowledge. I update my priors in response to new evidence, therefore I probably am.

    Observation isn’t reliable, that’s why science depends on falsifiability: I have observed things and drawn conclusions from those observations Here is an experiment that, given a specific outcome, will prove me wrong, please do your best to show that my conclusions do NOT adhere to your observations.

    Not all knowledge is based on faith. The flaw in this chain comes early on.

    Look, I’m a Stoic, I know that my senses and the inputs they give me are flawed and those flaws are out of my control. I know that my mind is flawed and those flaws are out of my control. I also know that they’re the only tools I have to perceive the world and I have to do my best with them.

    BUT.

    Confidence intervals are a thing. It’s not a binary between the poles of “I know for certain” and “I don’t know at all”. We can say, “I am confident, based on multiple observations by myself and the reported observations of others, that the sun will rise tomorrow, water boils at the same temperature adjusting for altitude, and the traits of the parents and grandparents can predict the traits of the offspring via Punnett squares.”

    The virtue of the scientific method is that the experiments must be repeatable. We don’t have to take it on faith. We can repeat variations of the experiment to raise or lower our confidence to acceptable levels.

    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.
