Wrestling with Knowing: A Weekly Dive into Philosophy’s Toughest Questions

From the ancient Greek skeptics all the way to modern neuroscientists, the simple question of what it means to truly 'know' something has been this relentless, unwinnable intellectual battle. Right. And last week we were talking about wrestling with these big philosophical dilemmas, and this… this feels like the one that sits underneath ALL of them. Exactly. The whole project of trying to figure things out depends on the idea that we can figure things out. But can we? Like, can we ever truly, one-hundred-percent know anything for certain?

Oh, that’s the deep end right away. I mean, my first instinct is to say, "Of course." I know the sky is blue. I know I'm talking to you right now. That's empiricism, right? I know what my senses tell me. See, I want to agree. But then I think about optical illusions, or how a stick looks bent in water. My senses can be fooled. They ARE fooled, all the time. So if the foundation is shaky, how can I trust the building? Mm-hm. Okay, so the senses are fallible. The rationalists would say that's why you can't rely on them.

Real knowledge comes from reason, from logic. Like, I know that two plus two equals four, not because I saw it somewhere, but because I can deduce it logically. It HAS to be true. I get that for math. But what about… love? Or justice? Or knowing who you are? You can't just use a formula for that. And even with logic, you're starting from axioms, from assumptions you have to accept without proof. You’re just a full-blown skeptic today, aren't you? You're channeling Pyrrho of Elis, just walking around saying, "I suspend judgment on that." Maybe I am!

But it's a genuine problem. Take science. We talk about scientific knowledge. But what is that, really? It’s just the best model we have right now, based on the evidence available. And we know it's going to be revised, or maybe even thrown out completely in a hundred years. But that's the strength of it! The fact that it's revisable is what makes it work. It's a process of getting less wrong over time. It's not about absolute certainty, it's about having a belief that is justified by evidence.

A justified belief… but is that the same as knowing? I can have a justified belief that my car is where I parked it. The evidence is: I parked it there, no one has a key, it's a safe neighborhood. But it could have been stolen. Or towed. I don't actually KNOW it's there until I see it. So for you, knowledge requires the elimination of ALL doubt? Even the most absurd, "what if a meteorite hit JUST my car" kind of doubt? Well, that’s the question, isn't it? Where do you draw the line? Because once you admit a little bit of doubt is acceptable, how do you stop the whole thing from unraveling?

What if this is all a dream? Or a simulation? The brain in a vat. Yeah. And the hard thing is, there's no argument that can prove you're NOT a brain in a vat. Any piece of evidence you point to, any sensation… could just be part of the simulation. It's a perfect, inescapable trap. And it makes me wonder if we're even asking the right question. Maybe the goal isn't to arrive at this final, static thing called "knowledge." Maybe the value is in the questioning itself. In holding our beliefs lightly.

In being open to being wrong. It's… um, it's a more humble way of being in the world, I guess. Yeah. It replaces the arrogance of certainty with the curiosity of doubt. You stop trying to have all the answers, and you get better at asking questions. And maybe that's a kind of knowledge, too. Knowing the limits of what you can know. So we can't ever truly know anything… except, perhaps, for the fact that we can't ever truly know anything. Now you're just trying to give me a headache. But yeah.

Something like that.
