It's the meaning. Your thinking has a ceiling on it, delimited by empiricism - exactly what a smart ape might think, pardon my impudence. — Wayfarer
I'm quite happy to be a smart ape. You don't seem to be. You want more. Luckily what apes as smart as us can do, think; how we are; is very very rich indeed.
When I said before that we only accept what can be weighed, measured, felt, sensed (including by instruments) this is what I mean. Empiricism amounts to the elevation of the senses to the sole criteria for valid knowledge (along with predictive power and replicability). — Wayfarer
Now you're making me into a bogeyman. Since you said you've read a lot of my posts, I thought you'd maybe noticed that I really like Heidegger and Spinoza; an arch-critic of instrumental rationality and naive empiricism and a full blown rationalist, both of them do metaphysics. I like philosophy!
The majority of the challenges I have brought against you in this thread have been conceptual. Mysticism vs reason as thinking styles, arguing against the claim that science is reductive, we even quoted from the same author at different points; we even made similar points about instrumental rationality (but we very very disagreed about where it comes from and what to do with it).
So I don't find it likely that I'm so blinkered I can't hope to understand how you see things.
But then he goes on to argue that natural selection can't account for mathematical skill or musical talent and many other capacities of mankind: — Wayfarer
Why would it ever need to? Natural selection can't account for why I trim my beard like I do. Therefore evolution is false? It's just (most likely) irrelevant to the theory.
A persuasive story goes that natural selection amplifies the presence of adaptive capabilities in populations of organisms over time (when they remain adaptive, when the ecology and communities within pose the same problems); development of the frontal cortex comes along with greater degrees of abstraction ability and language skills - tool use comes at some point, and we play like lower primates (who also make noises in play, and mock each other...). You put tools and play and high-order language together; whether it comes through a the evolution of a discontinuous presence/absence of a feature that allows recursive grammars or through a more gradual amplification primate abstractive ability doesn't matter; the ingredients are there. The rest? That's history. Literally history.
The point about classical philosophy was that it also in some sense took you to the border of what can be empirically known and points to what is beyond it. — Wayfarer
Science is never just about what can be empirically known, it's about what can be conceptually derived from or speculated about given what is known or suspected... Reason always points beyond the boundaries of experience; like memory and imagination do. Reason? A highly abstracted and linguistically mediated cognitive practice implicated with our episodic memory (prefrontal cortex declarative knowledge stuff) and anticipatory mechanisms (mirror neurons/internal state modelling). That it
allows us to discover the true nature of existence is a buy one get one free offer from the trait shop.
Our culture no longer has a lexicon to describe that beyond, — Wayfarer
I find it difficult to believe this; our culture has charted different orders of infinity, has understood the universe from the first moments to its eventual death, when people get bored at work they invent entire fictional universes in day dreams. Humans are both inscribed in reality and a fold within it.
The next stage is still more marvellous, still more completely beyond all possibility of explanation by matter, its laws and forces.
What kind of idiot would expect mechanical laws of particle motion to explain the evolution of sensory mechanisms?
Well, probably some physicists imagining that the universe's dynamics are as simple as those they can test by manipulating state variables... See previous stuff I wrote about reductionism. That you think this is a limit of reason itself rather than something people who have reasoned poorly (here) believe is baffling to me.
Reductionism, at its best, acts as a very long leash to loosely tie models of more complex systems to those beneath them which work well and on which we have good reason to think they supervene — Isaac
I agree with you broadly; mind depends on brain (in some ways), brain depends on mind (in some ways); but I don't like supervenience very much at all.
What supervenes on what is always the question. So, you can jury rig a concept like "neural correlate" to do anything you like, so much so that it provides no explanatory power or conceptual insights
over and above the brute stating of "when things in this register change there is a change in things of that register". That paper I referenced earlier, say, argued that psychological symptoms of PTSD (mind states) can remain unchanged even when neural architecture/hormone chemistry related to them changes. At that point you can say something like "well, the overall brain state still must have changed" or "the symptom is a type of brain state and not a token, and we only want token-token dependence between mind states and brain states" (which afaik is what happens)... It's just a rabbit hole devoid of any
how questions (or generalisations from procedural descriptions), it's sitting there like it's waiting for something. Anyway. Rant.
