Caveat number 3: Goodman, in Ways of Worldmaking, makes the point that reduction is essentially a myth in science, and if that's so, he can claim for his relativism that rather than it being anti-science, it empowers him to take each science at "full force", to endorse the work of biologists and chemists, for instance, without treating them as second-class citizens whose science isn't quite as true as physics. That's appealing.
I'll have to check that out. It seems to me that the track record for reduction is quite weak, and that the empirical support for it is not particularly strong. It's a bit bizarre that it still has the status of "assumed true until convincingly proven otherwise," (especially since what would constitute such proof seems hard to imagine, you can always posit smaller building blocks). I think this is just from inertia and that fact that there are multiple ideas competing to replace it, not just one replacement paradigm.
In particular, I think the arguments in Jaegwon Kim's monographs are air tight (as do a lot of people). If superveniance physicalism works the way it is normally posited, then we have causal closure (and thus epiphenomenalism) but we also absolutely cannot have strong emergence. That brings us to a weird place where:
A. There can be no emergence vis-á-vis first person subjective experience so we seem stuck with panpsychism, denying we exist, occasionalism, etc.; and
B. Natural selection can never select on "what experience is like," because experience never affects behavior (causal closure), which both seems implausible due to how good evolutionary arguments are for "why what feels good feels good" (and the inverse), and causes a host of profound epistemic issues (highlighted by Plantinga and David Hoffman).
Kim points out that this only works for substance metaphysics (i.e. objects properties inhere in their constituents), and IMO this is just another piece of evidence against that sort of thinking (suggesting relational metaphysics à la scholasticism or process metaphysics).
But this is all veering off topic.
In short, you can separate their claim into two: the substantive claim, and an additional claim that all other versions are wrong. * You can take both claims quite seriously, accepting one and denying the other. If they want to fight about it, you're not fighting about the substantive claim, but about their claimed monopoly on the truth, which you have taken just as seriously and denied.
Well here, I think the metaphysics of truth come into play. I can see many great arguments for types of relativism. Plenty of thinkers who have a strong conception of an absolute morality still allow for cultural relativity. You can have "the Good," and still have it filtered through social context such that "being a good priest," differs from "being a good soldier," which differs from "being a good king." And culture can obviously affect how things are best explained.
Plus, you can make a case for pragmatic relativism, which addresses caveat 3. I don't think you have to default on the possibility of a language(s) that carve the world at the joints to say "we clearly don't have that, and so different languages are more appropriate for different contexts." After all, the absolute is not reality with appearances removed, but reality +
all appearances.
So I agree with you. I don't see anything wrong with pragmatic cases for pluralism, and they don't need to entail that "everyone is always right." But I would not support the notion that "being right," simply has to do with game rules. For one, you can't ever get to an explanation for why games have the rules they do if you don't look outside of them.
People might talk about whether there's money in the bank or beer in the fridge, but they don't talk about whether money or banks or beer or refrigerators exist.
Wouldn't discussions of God fall into this category? That seems like a question of existence that is the organizing principle around which a great many people base their entire lives, and one with huge social and political implications.
The existence of "objective" moral standards would be another one that seems to be apparent in everyday life, often taking center stage. The same goes for the "meaning" and "purpose" of human life or humanity's telos.
The status of universals and numbers doesn't play nearly the same role that the aforementioned do, but people definetly seem interested in it. These creep into politics when we talk about education policy vis-á-vis mathematics. There are similar questions that have become quite politically relevant, i.e., "is gender or sex real?" or "is race real?"
And then you have the adoption of, at the very least, the post-modern lexicon by modern political movements. These days everything is about "deconstructing narratives," and there is "living your own truth," etc. The famous Giuliani retort: "truth isn't truth," appeals to "various ways of knowing," etc. suggest to me that pluralism is definitely relevant outside the context of the academy. I don't think this should be surprising, while most people in Scholasticism's heyday knew little of it, it had a major impact on the Church, education, and devotional life. Likewise, given the role "scientism" has as the dominant world view, it can't help but shape everyday experiences.
There may or may not be a truth out there, but how people comport themselves toward it is endlessly fascinating.
The idea of truth sitting "out there," also ends up presupposing some things if the view is that it lies outside us, existing "in-itself," waiting to be uncovered. In a mindless world, it seems to me that the truth/falsity distinction could have no content. Truth cannot be equivalent with being, since we can say truth things about what is not, e.g., "there is no planet between Earth and Mars." This is why Aquinas has truth inheritly bound up with a knower; "everything is known in the mode of the knower." The crucial distinction is that signs are always "how we know," whereas more pernicious forms of pluralism often seems to rely on the claim that "signs are
what we know." But if everything is signs, "appearance," then there can be no real reality/appearance distinction.
This is why I like Robert Sokolowski's concept of "grasping the intelligibility of things," when it comes to epistemology. We cannot grasp a thing's intelligibility in every context, but this doesn't mean we cannot grasp their intelligibility at all.
The modern preference for potency over act comes up here too. Arguments for pluralism often focus on things like: "we could shift the pronunciation of every English word, or change this formal system in infinite ways, etc." Yet, in actuality, we don't have infinite systems, we actually have a fairly limited number of popular ones. But then I think there are reasons that explain actuality.
