If by truth and falsity you mean something not definable in terms of doubt and belief in any way, then you are talking of entities of whose existence you can know nothing, and which Ockham’s razor would clean shave off. Your problems would be greatly simplified, if, instead of saying that you want to know the “Truth”, you were simply to say that you want to attain a state of belief unassailable by doubt.

For Peirce, a true belief is one that is indefeasible and unassailable—and indefeasible and unassailable for all the right reasons: namely, because it will stand up to all further inquiry and investigation. In other words,

if we were to reach a stage where we could no longer improve upon a belief, there is no point in withholding the title “true” from it.

From the standpoint of scientific inquiry, truth indicates not just accepted beliefs, but beliefs accepted in virtue of a certain method.…To science, truth denotes verified beliefs, propositions that have emerged from a certain procedure of inquiry and testing. By that I mean that if a scientific man were asked to point to samples of what he meant by truth, he would pick…beliefs which were the outcome of the best technique of inquiry available in some particular field; and he would do this no matter what his conception of the Nature of Truth.

Dewey has an expansive understanding of “science”. For Dewey, science emerges from and is continuous with everyday processes of trial and error—cooking and small-engine repair count as “scientific” on his account—which means he should not be taken too strictly when he equates truth with scientific verification.

Rather, Dewey’s point is that true propositions, when acted on, lead to the sort of predictable and dependable outcomes that are hallmarks of scientific verification, broadly construed. From a pragmatic standpoint, scientific verification boils down to the process of matching up expectations with outcomes, a process that gives us all the “correspondence” we could ask for.

Dewey eventually came to believe that conventional philosophical terms such as “truth” and “knowledge” were burdened with so much baggage, and had become so fossilized, that it was difficult to grasp the practical role these terms had originally served.

On these accounts truth plays a unique and necessary role in assertoric discoursen: without the concept of truth there would be no difference between making assertions and, to use Frank Ramsey’s nice phrase, “comparing notes” . Instead, truth provides the “convenient friction” that “makes our individual opinions engage with one another” and “is internally related to inquiry, reasons, and evidence”.

...new pragmatic accounts aim to show that there is more to truth than its disquotational and generalizing function. Specifically, this “more” is that the concept of truth also functions as a norm that places clear expectations on speakers and their assertions. In asserting something to be true, speakers take on an obligation to specify the consequences of their assertion, to consider how their assertions can be verified, and to offer reasons in support of their claims:

More specifically, without the norm of truth assertoric discourse would be degraded almost beyond recognition. Without the norm of truth, speakers could be held accountable only for either insincerely asserting things they don’t themselves believe (thus violating the norm of “subjective assertibility”) or for asserting things they don’t have enough evidence for (thus violating the norm of “personal warranted assertibility”) (Price 2003: 173–174). The norm of truth is a condition for genuine disagreement between people who speak sincerely and with, from their own perspective, good enough reasons. It provides the “friction” we need to treat disagreements as genuinely needing resolution: otherwise, “differences of opinion would simply slide past one another” (Price 2003: 180–181). In sum, the concept of truth plays an essential role in making assertoric discourse possible, ensuring that assertions come with obligations and that conflicting assertions get attention. Without truth, it is no longer clear to what degree assertions would still be assertions, as opposed to impromptu speculations or musings. (Correspondence theories should find little reason to object: they too can recognize that truth functions as a norm. Of course, correspondence theorists will want to add that truth also requires correspondence to reality, a step “new” pragmatists will resisting taking.)
