The topic of this video touches upon my insufficiency of language thesis. Tim Maudlin defends language realism but only to the extent that ‘we can use it to describe the world and that some of those descriptions are true’.
The challenge, then, is determining which descriptions are true. I’ve discussed a couple of my positions on this.
The Truth About Truth
Firstly, we can only perceive what is true as we have no access to absolute truth. The best we can achieve is an asymptotic function approaching truth, a notion that resonates with Hilary Putnam’s concept of internal realism (pdf). Putnam argues that truth is not a matter of correspondence with a mind-independent reality but is instead tied to our conceptual schemes. This means that what we consider “true” is always shaped by the language and concepts we use, making our understanding inherently partial and context-dependent. Even then, we have no way to determine how close to truth our perception is. It just has to feel true—an idea that aligns with Putnam’s pragmatic conception of truth, where truth is something that emerges from our practices and inquiries, rather than being a fixed point we can definitively reach. In terms of physics, this underlying reality may be relatively more stable than abstract concepts, which are ephemeral and shifting sands.
The Rhetoric of Truth
Secondly, given that we have no access to objective truth, we can only expect subjective or relative truths. This brings us to Putnam’s critique of the metaphysical correspondence theory of truth. According to Putnam, the idea that language can perfectly correspond to an external reality is flawed. Instead, truth is what can be justified within a particular conceptual framework, making all truth somewhat relative. This leaves us open to rhetoric—the more convincing argument wins, regardless of whether it reflects an objective reality. In fact, as Putnam’s ideas suggest, the most persuasive argument might favour an incorrect position simply because it resonates more with our internal conceptual schemes, not because it corresponds to an external truth. This has happened many times historically—or has it?
Conclusion: Language, Truth, and the Influence of Rhetoric
Putnam’s work reminds us that language is deeply connected to our understanding of the world, but it is also limited by the conceptual frameworks within which it operates. While language helps us navigate and describe the world, it cannot provide us with direct access to objective truth. Instead, it gives us tools to construct truths that are internally coherent and pragmatically useful, though always subject to change and reinterpretation. As we engage with rhetoric and persuasion, we must remain aware that the truths we accept are often those that best fit our current conceptual schemes, not necessarily those that best correspond to an elusive objective reality.
