Good. So what we want to know is, does the coupling of the methodologies for determining what is true and what is genuinely justified result in a vicious circle?
That it is a circle seems clear, but that may not be a problem. We might start by asking, is it possible to determine what is true without using the methods that "lock justification onto truth-tracking"? -- that is, without engaging in justification?
I'm guessing not, but then how do we respond to the objection that we have "collapsed into each other" the criteria for truth and justification? Note that this objection doesn't depend on claiming that justification has been reduced to "social agreement," opening the door for some invidious form of relativism. The criteria for both truth and justification can be as "objective" as you please, but we still have the problem of whether they are indeed two separate legs of the tripod. — J
Great, this is exactly the pressure point to push on, and here’s my view.
There is a circle here, but it is a benign, hinge-supported feedback loop, not a vicious circle and not a collapse. Truth and justification remain conceptually distinct, two different “grammars” in Wittgenstein’s sense, even though, in practice, our only route to truth runs through justificatory methods.
Truth: how the world is (a world constraint on speech acts).
Justified: whether one’s reasons meet the public standards of the operative language-game (science, law, everyday perception, math).
We don’t reduce truth to justification, and we don’t pretend justification is free of truth. We couple them so that justification tracks truth (anti-false-grounds + practice-safety), and Wittgensteinian hinges stop the regress (and circularity) that would make any coupling impossible.
Why this isn’t a collapse (three quick tests)
I can be genuinely justified yet false. Example: at T1, I check the official schedule, the app, and the platform announcement, public criteria are satisfied. At T2, a last-minute disruption cancels the stop. Justification stands (by the practice’s rules at T1), truth doesn’t. They come apart.
Luck test (Gettier without false grounds; environmental luck).
I can be true yet unjustified: I guess, and I’m right. Or I form the belief by a method that would easily be wrong in nearby cases (Fake-Barn County). That’s truth without knowledge because it flunks practice-safety. Again, they come apart.
Methods that systematically miss reality (bad calibration, poor replication, unchecked bias) are revised or rejected. That asymmetry, the world’s recalcitrance, shows that justification is answerable to truth, not identical with it.
Conclusion: Different roles, different failure modes, no collapse.
Why the “circle” is benign, not vicious
You asked: “Can we determine what is true without the very methods that ‘lock justification onto truth-tracking’?” In practice, no, we have no non-method magic eye for truth. But that does not mean identity or vicious circularity.
It’s like a clear window and a landscape. You only see the landscape through the window, but the window isn’t the landscape. You can replace or polish the window; the hills don’t move with your squeegee.
The loop is externally constrained: prediction, intervention, replication, calibration, cross-examination, and defeater management are world-sensitive tests. When they fail, the world corrects us.
Hinges, bedrock certainties like “there is an external world,” “other minds exist,” “meanings are generally stable,” are not evidence; they are the conditions for evidence to count. They prevent regress without pretending to “prove” themselves from within. My Gödel analogy captures this logic: unprovable statements that enable the system are a feature, not a bug.
Why this isn’t “objective-in-name-only”
You’re right that objectivity matters, and I’m not smuggling in “mere social agreement.” Public criteria in this framework are geared to track reality:
Anti-false-grounds: your case for P may not essentially run through a false premise.
Practice-safety: given the domain’s recognized error profile, the same method wouldn’t easily have delivered a false belief in nearby cases.
Error-controls: replication, calibration, pre-registration, blinding, proper scoring (e.g., Brier), independent testimony, valid inference, and correct concept use.
These are norms with teeth. They preserve the independence of truth while bending methods toward it.
The tripod stays a tripod
Truth = world-constraint (not defined by our procedures).
Belief = our doxastic stance.
Justification = public rule-governed standing (anti-false-grounds; practice-safe).
Yes, the only epistemic way to reach truth is via methods, but method-dependence of access does not entail identity of property. The two legs, truth and justification, remain distinct, even as they are methodologically coupled and mutually calibrated by the way the world pushes back.
That’s my Wittgensteinian JTB: no collapse, no vicious circle, just a disciplined coupling inside hinge-enabled practices that keeps knowledge world-answerable.
