Plato demonstrated in The Theaetetus, that "knowledge" as we know it cannot be described as JTB. This is because the possibility of falsity cannot be excluded, therefore we cannot hold truth as a criterion. In other words, the requirement of truth cannot be justified, therefore the idea that knowledge is JTB cannot itself be knowledge. — Metaphysician Undercover
However, we typically regard knowledge as stable and reliable, a foundation we can trust. Gettier problems like this challenge the traditional JTB definition by revealing cases of accidental knowledge, suggesting that justification, truth, and belief alone are insufficient for genuine knowledge. — DasGegenmittel
Knowledge is treated today as if it were static and timeless, as Plato might have suggested, [...] — DasGegenmittel
You mention that knowledge in everyday life isn’t really “stable and reliable” the way we often wish it were—or the way the JTB definition implies. The Gettier case is really just an elegant illustration of this. You suggest instead focusing on practical justification before taking action.
This aligns very well with my introduction of Dynamic Knowledge: we might try to treat knowledge as a solid foundation, but in reality, there are always gaps and uncertainties. That’s exactly why I propose that in dynamic contexts, we shouldn’t rely on the illusion of “eternal validity,” but rather see knowledge as an ongoing process that must handle uncertainty and revision (JTC). — DasGegenmittel
Plato and Aristotle both knew—as I believe you do as well—that JTB alone is insufficient in dynamic contexts (though it may suffice in static ones), contrary to the dominant interpretation today. — DasGegenmittel
Every perception—even when enhanced by technological means—is only an approximation of reality — DasGegenmittel
Your proposal works well as a practical heuristic. But without a clearer framework, many of the beliefs we treat as “knowledge” wouldn’t actually qualify — not because they’re false, but because their justification dissolves over time. — DasGegenmittel
In my work on Dynamic Knowledge (DK) and Justified True Crisis (JTC), the goal isn’t to complicate things unnecessarily, but rather to methodically account for that uncertainty — without falling into dogmatic pseudo-certainty...
...JTC doesn’t just focus on the immediate utility of a belief for action. It also emphasizes the awareness of epistemic crisis — the recognition that our justification may be context-sensitive, fragile, or even coincidental. — DasGegenmittel
Imagine you see a bottle sitting on a table at 12:00. You say, “The bottle is intact.” At 12:02, you hear a crash — it has fallen and shattered.
Did you know the bottle was intact?
Under JTB: ✔ justified (you saw it), ✔ true (at the time), ✔ believed — so: knowledge.
But epistemically, your statement is unstable. What you actually knew was: “The bottle was intact at 12:00.” Without temporal indexing, your statement becomes retroactively misleading — even though it was “true” in a narrow JTB sense. The JTB model implicitly assumes that once a belief qualifies as knowledge, it remains so — even if the real-world referent (like an intact bottle) changes moments later, unless we explicitly update or retract the claim. — DasGegenmittel
You pointed out the tension between Parmenides’ being and Heraclitus’ becoming, referencing Aristotle, who saw these opposites as irreconcilable. Your proposed solution is a dualism that separates both aspects. This is precisely where my distinction between Static Knowledge and Dynamic Knowledge comes in:
• SK refers to timeless, secure knowledge (e.g., mathematics).
• DK is tied to changing conditions (e.g., the fastest route to work today). — DasGegenmittel
Immutable and timeless elements (see deduction) are often conflated with mutable and temporal ones (see induction), as is the case in many Gettier examples. The expectation that knowledge should work the same way in inductive contexts as it does in deductive reasoning is, as you imply, unfounded. The epistemic monism currently dominant in the field is therefore deeply problematic. That’s why I wrote my paper Justified True Crisis—because this issue often goes unrecognized. It’s reassuring to know there are people out there who think along similar lines. — DasGegenmittel
In relation to Plato’s Theaetetus, you argue that knowledge cannot be understood as “Justified True Belief” (JTB) because we can never completely rule out the possibility of falsehood. Therefore, “truth” cannot serve as a sufficient criterion, and JTB itself cannot be equated with knowledge. This interpretation reflects a typical post-Gettier skepticism, namely that the concept of truth itself remains “inaccessible.”
In my model, this doesn’t mean we discard truth altogether. Rather, the discussion around Gettier cases (e.g., the stopped clock) highlights the need to distinguish between static and dynamic knowledge. We still need “truth” as a goal and standard for knowledge, but we must accept that in DK-domains, our beliefs are constantly subject to revision, and we can never claim absolute certainty in changing environments. — DasGegenmittel
Personally, I find no issue between JTB and change. That's what proper indexing/timestamps are for. — creativesoul
Timestamps, while not sufficient, are nevertheless necessary for any attempt to articulate change. The shift from being to becoming cannot be described adequately through a chain of static states. As Aristotle argued, change is not captured by a succession of positions; rather, it exists between them. It’s a different kind of phenomenon—continuous, processual, and epistemically elusive. Yet without temporal markers, we would lack the coordinates needed to locate, compare, or even recognize shifts in state. Timestamps provide the necessary structure within which the insufficiency of static snapshots becomes visible. They do not capture becoming, but they allow us to trace its outline. — DasGegenmittel
In this context, DK is not a lack of certainty, but an ideal in its own right. Knowledge is modeled as a limit process: not something one has, but something one approaches. The limit in the DKa and DKh formulas represents the asymptotic approach to ideal knowledge in dynamic contexts. It shows that knowledge evolves step by step, reducing uncertainty over time, but never fully reaches absolute certainty: see as well bayesian epistemology as complementary approach. It models the continuous refinement of justified beliefs under changing conditions. I distinguish two complementary dimensions: — DasGegenmittel
JTC mirrors the structure of JTB—justification, truth, and belief remain essential—but reinterprets them dynamically. Truth is no longer static but contextualized within time. Justification adapts, and belief becomes a crisis-aware assertion. Together, these preserve the functional core of JTB while enabling knowledge to operate under uncertainty. JTC is not a rejection but a temporal simulation of JTB—an epistemic snapshot in motion, like Zeno’s arrow suspended mid-flight. — DasGegenmittel
there's no oracle who can tell us if that belief satisfies the T or not. — flannel jesus
