So now we have not just “knowledge” but also “real knowledge”? I have experiences of the colour green from the “real world” (I am appeared to greenly), and I know my favourite colour is green. Is this “real knowledge” or just plain old “ordinary” knowledge?
As in my previous post, “knowledge” as a term has different implications, depending on its epistemic credentials. Qualia like sense of color (which is different than 2nd order senses like “green is my favorite color”) are different
kinds of statements about the world – private, personal, subjective. That’s perfectly legitimate to invoke, and is only problematic when it gets confused with statements that are amenable to shared, objective analysis and review. These different senses of “know” are
way useful as a kind of shorthand, indexed to the various epistemic backings for each. Equivocation is a constant problem to watch out for here, though, because of that, as it is in so many other parts of the reasoning and communication processes.
Ok, so do you consider the statement “The universe existed 5 minutes ago” to be knowledge (or “real knowledge”) despite it’s unfalsifiability?
No, not in the general sense. The belief that reality is as old as the evidence suggests is the most reasonable, parsimonious conclusion, but we cannot falsify
Omphalos. We can “know”, scientifically speaking, because scientific epistemology is predicated on both parsimony and the virtue of falsifiability. We could perhaps falsify the “ancientness” of the universe by uncovering strong evidence that supports “Last Tuesdayism” as a real process or phenomenon. The age of the universe as a positive claim
is subject to falsification and positive support, qualifying it as ‘knowledge’ in the scientific sense. But the reverse case does not hold; there is no way to falsify a claim that by nature avoids all means of detection.
On the contrary, I would respectfully argue that you are (or at least seem to be, from some things you say)! I consider warrant to be that something which makes mere true belief into knowledge. I certainly do not consider falsification to be warrant.
Ok, that’s good, I would agree that knowledge (i.e. warranted true belief) does not require falsifiability.
OK, some ground gained between us, there, then.
What does this mean? Should we downgrade the belief that other minds exist because said belief is unfalsifiable? Does that mean we should be less keen to accept such a belief when compared to other beliefs that are falsifiable?
If they are competing on equal terms, then yes. The reason we accept other minds is that a) we “galvanize” that belief in our brains at such a young, uncritical age we are hardly at liberty to undo, making it a moot point in any case, and b) even to the extent we manage to doubt it, it becomes transcendentally absurd, for the very same reason thinking that the extramental world isn’t real ( in the efficacious sense) is absurd, and worse – lethally self-defeating.
One must use language to deny the utility of language – a serious transcendental problem, that. On the same line, one can’t reveal one’s doubts about other minds without affirming the legitimacy of the other minds one is revealing them to.
But where you have propositions that address the same question, and one explanation is perfectly unfalsifiable and the others are eminently falsifiable, no matter how the evidence bears out, there is a profound depth of meaning as a statement about reality in propositions that are falsifiable-in-principle that that unfalsifiable propositions do not have. To the extent one embraces an unfalsifiable explanation, one simply avoids the question, and accepts meaninglessness in favor of meaningfulness regarding the concepts of “true” and “know”.
Why should anyone in philosophy or theology care about Parsimony beyond the practice of science? Parsimony works in science because science is utilitarian, it only cares about what “works”. An un-complicated spanner is better at tightening nuts than a complicated one. But who cares about this principle when one is wanting to know the truth about how things really are? Economy is no necessary indication of truth.
No, it’s not. And indeed, many truths end up being fantastically more complicated than some of the simpler hypotheses that sought to explain them. Parsimony isn’t like what you are describing however. A simple wrench and a more complicated wrench that do the same work with same effectiveness both leave the nuts equally tight. The “complicated” part is not
wrong in any sense beyond it being extraneous, superfluous. It’s just not needed for getting the job done.
That’s an important distinction you’ve missed, because there, the “truth” is accounted for on both cases, but one with some amount of unneeded “extras”. If the “complicated” wrench did the job better, it would be preferable to the simple wrench as the nuts would be tighter, or tightened faster, etc. Parsimony is just the principle that isolates what is minimally necessary for truth, for doing the job, and identifying the other parts that “come along for the ride”. A crucial preamble to the principle of parsimony is “all other things being equal…”
Parsimony is the focus on identifying what is
needed to model truth, and what is not.
