This post by way of pointing out how our own conceptions on what constitutes philosophy are different, so we are talking past one another.
Okay, sure. Water cannot be divisible and indivisible. This is a true contradiction. Yet this is the first time I've seen you presenting Aristotle as a proponent of indivisibility. Earlier you were talking about teleology. — Leontiskos
The purpose of using names isn't to demonstrate what I've read and understood, but to refer to a shared body of knowledge between speakers. So when I say "Aristotle", I presume you understand Aristotle well enough and modern science well enough to be able to put together the dots that teleology and modern science, especially of the enlightenment era, are in conflict.
I switched to divisibility because the example is as good as the teleological one -- namely, I don't know if Lavosier, on a personal level, might have believed there was some kind of teleology behind water, but the whole enlightenment project basically rejects teleology in favor of efficient causation for its mode of explanation -- this is one of the primary reasons people reject Enlightenment era materialism and go in various ways.
There is no strict division between philosophy and science. Aristotle is generally referred to as a scientist, perhaps the first, and yet this does not disqualify him as a philosopher. — Leontiskos
I agree. My inclination to using examples is to overcome this -- we don't have to define things in terms of their necessary and sufficient conditions, but can instead use paradigmatic examples to show what we mean: definition by ostension.
So there are three names that we've been using, and with those names I'll draw some differences:
Aristotle is an ancient scientist and philosopher
Lavoisier is a modern scientist
Kripke is a modern philosopher.
Because I'd draw a distinction between ancient and modern science -- they don't operate the same. And Kripke counting as modern because of the scope of the question which utilizes Aristotle.
Right... I guess I would need you to set out the thesis that you believe to be at stake. I wrote that post with your emphasis on falsehood in mind. You have this idea that Lavoisier must have falsified something in Aristotle. The whole notion that we can grow in knowledge presupposes that we have something which is true and yet incomplete, and which can be built upon. — Leontiskos
I think all it takes to grow in knowledge is to plant seeds and see what happens. And what had been can die, and what is will stop being.
But noting here: even our notions of "falsification" are at odds. So perhaps we cannot appeal to falsification in our back-and-forth, because even this is being equivocated in our dialogue.
I assure you that by my understanding of falsification that Lavasioer does not falsify Aristotle, and that this is pretty much just another rabbit whole to jump down before getting to the topic "What is real?"
To say what's at stake: I don't think science delineates what is real. I also think that the project towards finding essences using the sciences is doomed to fail -- the big difference between Aristotle's and our day is the sheer amount of knowledge that there is. In Aristotle's day it probably seemed like a reasonable project to begin with the sciences and slowly climb up to a great metaphysical picture of the whole.
But any one scientist today simply can't have that perspective. Looking at
https://pubmed.ncbi.nlm.nih.gov/ their tagline on the front page states "PubMed® comprises more than 38 million citations for biomedical literature from MEDLINE, life science journals, and online books."
Aristotle could review all the literature that was in his day and respond to all his critics and lay out a potential whole. But he didn't have so many millions of papers or forebears to deal with. And I'd be more apt to look to the Gutenberg Press to explain this difference.
But this is only if we treat metaphysics as exactly the same as science, too. That was Aristotle's goal, but it need not be metaphysics goal. I'm more inclined to think that these metaphysical ways of thinking are ways of dealing with the sheer amount, the multiplicity, that one must consider to make a universal generalization. The generalizations, rather than capturing a higher truth, is a way of organizing the chaos for ourselves.
So what's at stake -- the usual stuff. The relationship between science, philosophy, and whether science can or ought to have or how much they ought to have a say in "What is real?"
It is odd to say that it is false. If it is "good enough" to begin understanding, then it simply cannot be wholly false. If it is wholly false then it is not good enough to begin understanding. — Leontiskos
Another terminological difference. I tend to think attributions of "not wholly false" or "not wholly true" can be reduced to a set of sentences in which the name is sometimes the predicate and sometimes not the predicate, and so we need only refer to the conditions for each. "False" doesn't admit of degrees in a strict sense, I don't think, though it's a common way of parsing the world in our everyday reasonings.
If I know something about water, and then I study and learn more about water, then what I first knew was true and yet incomplete. It need not have been false (although it could have been). Note, though, that if everything I originally believed about water was false, then my new knowledge of water is not building on anything at all, and a strong equivocation occurs between what I originally conceived as 'water' and what I now understand to be 'water'.
For Aristotle learning must build on previous knowledge. To learn something is to use what we already know (and also possibly new inputs alongside).
I agree that Aristotle would accept and expect this -- but I don't think he'd predict what's different.
— Moliere
Right. He knows that there is more to be learned about water even though he does not know that part of that is H2O.
So what I see is that skepticism, rather than security, is the basis of knowledge. Jumping out into the unknown and making guesses and trying to make sense of what we do not know is how new knowledge gets generated -- if we happen to find some connections to what we thought we knew down the line that's a happy accident.
The emphasis on security, I think, leads one to complacency. Rather than testing where we are wrong we defend when we are right.
Right, good. Let's just employ set theory with a set of predications about water:
Aristotle: Water: {wet, heavy unlike fire}
[Call this AW]
Lavoisier: Water: {wet, heavy unlike fire, H2O}
[Call this LW]
On this construal Lavoisier's understanding of water agrees with Aristotle in saying that water is wet and heavy unlike fire, but it adds a third predication that Aristotle does not include, namely that water is composed of H2O.
What is the relation between AW and LW? In a material sense there is overlap but inequality. Do Aristotle and Lavoisier mean the same thing by "water"? Yes and no. They are pointing to the same substance, but their understanding of that substance is not identical. At the same time, neither one takes their understanding to be exhaustive (and therefore AW and LW do not, and are not intended to, contradict one another).
Now the univocity of the analytic will tend to say that either water is AW or else water is LW (or else it is neither), and therefore Aristotle and Lavoisier must be contradicting one another. One of them understands water and one does not. There is no middle ground. There is no way in which Aristotle could understand water and yet Lavoisier could understand it better.
If one wants to escape the problematic univocity of analytical philosophy they must posit the human ability to talk about the same thing without having a perfectly identical understanding of that thing. That is part of what the Aristotelian notion of essence provides. It provides leeway such that two people can hit the same target even without firing the exact same shot, and then compare notes with one another to reach a fuller understanding. — Leontiskos
I think your construal of AW and LW is such that they look like they agree more than they do not agree. Maybe, but note this is why the historical method is more interesting than stipulated definitions.
I'd go back to the distinction in this post I made between Aristotle, Lavoisier, and Kripke.
Aristotle's concern is philosophical and scientific, and he lives in an era where his project is feasibly both philosophical and scientific. He has a much wider theory of water that conflicts with the enlightenment, mechanistic picture of H2O which Lavoisier is credited with determining. I think of
hisLavoisier's work primarily as a scientist because his work as a scientist was in improving analytic methods, and it was due to his care towards precision that he was able to demonstrate to the wider scientific community the ratio of Hydrogen to Oxygen you get with electrolysis. So maybe there's some philosophical work of his I do not know, but I'd say this work fits squarely within the scientific column, even if we don't have strict definitions to delineate when is what.
And, likewise, Kripke is making a point about whether essences can be made viable in the 20th century after they had been largely abandoned by contemporary philosophy (even if there are other traditions which keep them). So he's a philosopher, but if science turns out to be wrong about the whole H2O thing his points will still stand(EDIT:or fall) regardless. So he's not a scientist, in this particular instance.
