This thread grows out of a question that kept surfacing in the On Certainty reading thread but pulling the sequential discussion off track. The question is big enough to need its own space, so I’m giving it one.
The Phenomenon
Start here. You’re sitting in a chair right now. You didn’t test it first. You didn’t check whether it would hold you, examine its joints, calculate its load tolerance, or reason from past experience to the conclusion that this particular chair on this particular occasion would bear your weight. You sat down. Before that, you walked into the room. You didn’t establish that the ground would continue to hold you with each step. You reached for your coffee. You didn’t first work out whether the cup would still be there when your hand arrived, or whether your hand would do what you intended. You started reading this post. You didn’t pause to verify that the words would continue to mean what they meant a moment ago, or that the person who wrote them exists.
None of this is carelessness. It’s what being a functioning creature looks like. We act, and our acting is saturated with certainty, but not the kind philosophy usually means by that word. This isn’t knowledge. It isn’t assumption (you didn’t adopt any of this). It isn’t epistemic certainty, the kind established by investigation and grounded in evidence. It’s the certainty that lives in the acting itself, in the sitting, the reaching, the trusting. Wittgenstein spent the last eighteen months of his life circling this phenomenon, and it turns out to be remarkably hard to talk about, not because it’s obscure but because the word “certainty” does at least four different things in this neighborhood and using it without qualification invites confusion at every turn.
The Language Problem
Here’s the first difficulty, and it’s not a failure to find the right words. It’s a substantive philosophical point.
Most of our philosophical vocabulary (“knowledge,” “assumption,” “justification,” “proposition”) was built for work inside a framework. These are terms for things we do once we’re already up and running: forming beliefs, testing claims, weighing evidence, drawing conclusions. But the certainty that shows itself in your sitting without testing isn’t inside the framework. It’s what the framework rests on. And our language doesn’t have clean terms for this, because the terms were designed for the epistemic work that happens after the certainty is already in place. We’re trying to describe, from inside, what “inside” rests on. The terminological difficulty is a symptom of the problem, not a failure to solve it.
Wittgenstein felt this himself. At OC 76 he says his aim is “to give statements one would like to make here but cannot make significantly.” Not won’t make. Cannot. The available forms of expression resist what he’s trying to say.
A second language warning. The secondary literature on OC introduced the term “hinge proposition.” Witt never used it. The image comes from OC 341–343, where he compares certain things to the hinges on which a door turns, viz., the door moves, the hinges stay put. That image is useful. But “hinge proposition” smuggles in exactly what Witt is working against. It takes the certainty your sitting-without-testing expresses, certainty shown in acting, and repackages it as a proposition, a sentence with a truth value, the kind of thing you can believe or doubt or justify. And then the whole discussion slides back into the epistemological machinery Witt was trying to get beneath.
This thread will use “hinge” on its own. No “proposition” appended. When the discussion requires a term for the formulated, linguistic versions, I’ll say so explicitly.
Three Levels
Look again at what’s going on when you sit without testing. There are layers here, and they aren’t all the same kind of thing.
At the deepest level, objects persist, other beings exist, experience continues. You don’t hold these as positions. You couldn’t function without them. A creature that genuinely doubted whether objects continued to exist when unobserved wouldn’t be a creature with an interesting philosophical view. It would be a creature that couldn’t act at all. These aren’t commitments you’ve undertaken. They’re conditions of being a creature that acts in a world.
At a second level, the ground holds, your body responds to your intentions, space and time have the structure they seem to have. These are still prelinguistic (a dog operates with all of them) but more specific than bare object-persistence. They can, in principle, fail. The ground could give way. Your body could stop responding. But they don’t function as hypotheses you’re betting on. They function as the background against which hypotheses become possible.
At a third level, formulations. “The earth has existed for a very long time.” “Physical objects continue to exist when unperceived.” “My name is Sam.” “I have never been to the moon.” These are the ones that look like propositions, and this is where the confusion starts. They can be stated, debated, doubted. But Witt argues they play a peculiar logical role (OC 136). They don’t function the way ordinary empirical claims function. They’re more like the scaffolding that holds the structure in place while work goes on inside it, and some of this scaffolding can shift over time. What counts as unshakeable in one era can become revisable in another, and vice versa (OC 96–97, the riverbed metaphor, where what was bed becomes channel and what was channel becomes bed).
Here’s the crucial point - when I describe a hinge propositionally (“objects persist,” “the ground holds”) I haven’t shown that the hinge is a proposition. The description comes after the fact. It’s a map of something that isn’t itself a map. The dog sits on the chair without testing it too, and the dog has no propositions.
All three levels are forms of hinge certainty, the certainty that stands fast, shown in what we do. But they differ in important ways. The deepest hinges are prelinguistic, operative before language enters the picture at all. The second level continues to operate nonlinguistically even in creatures who have language. The third level is linguistic, held fast by what lies around it in the system, and it can shift over time in ways the deeper levels cannot.
Moore and the King
The passage that crystallizes the framework problem is OC 92:
“However, we can ask: May someone have telling grounds for believing that the earth has only existed for a short time, say since his own birth? — Suppose he had always been told that, — would he have any good reason to doubt it? Men have believed that they could make rain; why should not a king be brought up in the belief that the world began with him? And if Moore and this king were to meet and discuss, could Moore really prove his belief to be the right one? I do not say that Moore could not convert the king to his view, but it would be a conversion of a special kind; the king would be brought to look at the world in a different way.”
What Wittgenstein is describing here is a limit. Not a limit of Moore’s cleverness, or of the evidence available to him, but a structural limit on what argument can accomplish when two people don’t share a framework. Moore can present his evidence. But his evidence counts as evidence because of standards that are themselves part of his framework. The king has different standards, not because the king is irrational, but because standards don’t float free of the framework they belong to.
Moore cannot prove his view to the king. He might convert him. But conversion is not proof. Proof operates within a shared framework. Conversion is a shift from one framework to another. And Wittgenstein is remarkably honest about what this means, i.e., at the level where frameworks differ, argument runs out.
A Convergence
Here’s what makes this more than a problem for Wittgenstein scholars.
Kuhn, working independently on the history of science, arrived at something structurally parallel. Scientific paradigms are not simply collections of theories. They include the standards by which theories are evaluated, the exemplars that define what a good explanation looks like, even the ontology that determines what exists to be explained. When paradigms conflict, the disagreement can’t be resolved by appeal to the evidence, because what counts as evidence is partly determined by the paradigm. This is the incommensurability problem. It’s OC 92 in a lab coat.
Gödel, working in formal logic, showed that any sufficiently powerful formal system contains truths it cannot prove from within. The system cannot ground itself entirely using its own resources. No amount of internal rigor closes the gap.
Three thinkers, three domains, one structural insight: no rule-governed system can fully ground itself from within. The framework’s resources are insufficient to justify the framework.
The Question
So, the framework has limits. This much seems hard to deny once you see it.
But what follows from this? That’s where the real work begins, and it’s what this thread is for.
Witt describes the structure. But he also, I think, points toward the answer, even if he doesn’t follow it all the way. This is where I’ll be developing a reading that goes beyond what Wittg straightforwardly says.
OC 204: “Giving grounds … comes to an end; — but the end is not certain propositions’ striking us immediately as true, i.e. it is not a kind of seeing on our part; it is our acting, which lies at the bottom of the language-game.”
Acting. Not reasoning, not judging, not arriving at conclusions. Acting. The deepest ground of the framework is experiential, not propositional. The creature acts, and its acting is the certainty. The believing and the doing are one thing at this level, and both are prior to the framework that describes them.
If the deepest hinges are experiential rather than propositional, and if the framework’s limits are structural, then the question becomes: is the limit absolute? Is there nothing beyond the framework but more framework? Or can experience cross boundaries that argument cannot?
This thread will explore that question. We’ll look at different kinds of frameworks (scientific, religious, philosophical, political) and ask what holds them up, where they run into their own limits, and whether there’s anything honest to say about what lies beyond them.
The OC reading thread will continue its sequential work. Framework questions that arise there can be brought here. And the argument I’ll be developing, that experience is more fundamental than any framework and that it can, under the right conditions, extend the framework from within, will get tested in open discussion.
