Professor, would you say logic is the foundation of philosophy?
@onemorebrown
@onemorebrown Күн бұрын
My own view is that arguments are the method of philosophy, and arguments express reasoning. So I would say reasoning is the foundation of philosophy. Logic, as we typically use that word, is a theory of reasoning and so requires reasoning. It is thus just another part f philosophy and not the foundation. But I am sure you could disagree with this!

Goff did respond to the shombies argument though? It'd be nice if he developed the response and put it in print, but he did respond during your episode with him. He said that the zombie argument and shombie argument are symmetrical and both concievable, but only if you accept dual carving, and if you reject dual carving, zombies are conceivable and shombies aren't, and he argued we should reject dual carving. Is there anything that response misses, or do you just accept dual carving?

Yes my point was that he never replied in print and just goes o asserting that the conceivability argument is successful (in print). I don't accept dual carving, but I don't envy it either. I don't think it has the consequences that he thinks it does, but even if it did I don't see the problem with a rejection of a priori knowledge. I also don;t think we need dual carving in order to get the argument working. Goff acknowledges that there are all kinds of things we can't read off our transparent concepts of experience. For example we don't know if naive realism is true, or if they are composed of more fundamental micoexperiences, and so on. I think that is enough to get the idea that we grasp the experiential nature but not the fuller property, which may be physical.

Unrelated to the topic of the video, but I wondered if you would consider a discussion with Graham Priest. I know he's a logician and not a philosopher of mind, but his views on god-particularly as they have manifested themselves through eastern traditions-nothingness as the ground of reality, metaphysics, physicalism, etc. would be interesting to engage with as I'm sure you could push him further than most interviewers who have talked to him for YT videos.

i haven't read your shombies paper yet (apologies). But from the sounds of it, you are making a type-b physicalist move like the one katalin balog makes in "in defense of the phenomenal concept strategy", where she suggests, among other things, that it's conceivable that a (minimal) physical duplicate of our world is a phenomenal duplicate. If so, then the second premise of the conceivability argument linking an epistemic gap to a metaphysical gap is conceivably false and -- given that this principle if true is true *a priori* -- it is false. hence, the conceivability argument fails at premise 2. does that sound right to you? i don't know if that's what frankish had in mind back when he wrote the anti-zombies paper, but with his turn to illusionism, he seems much more in the type-a camp.

I am very sympathetic to Balog's view! My strategy, though, is to grant the 2D framework to the opponent and to argue that one or the other of zombies must be inconceivable, but we can't know which (currently)

Wouldn't the symmetry to the zombie argument (such as to put their conceivability's in conflict) need to be a kind of "conceivability of a lack of a conceptual gap between physical and phenomenal properties", or in other words, a "conceivability of the inconceivability of zombies"? But wouldn't this be incoherent for those who find zombies conceivable in the first place? Wouldn't the mere positive conceivability of x necessarily commit one to denying the notion of its own inconceivability, thereby shombies/ anti-zombies? It certainly seems that the conceivability of zombies is more readily apparent than their being inconceivable such as to, if nothing else, grant more weight to "zombies-over-anti-zombies-conceivability" compared to the alternative. If the only point is that conceivability isn't in-itself anywhere close to a sufficient guide to metaphysical possibility, then that's obviously fair. I'm sorry if I misinterpreted anything (or everything).

I think the shombie argument is effective for showing conceivability is an unreliable guide to metaphysical possibility, I have pointed to it a few times when p-zombies are brought up. A lot of people misunderstand it for some reason, or maybe I am the one who is misunderstood. A common critique is that the shombie argument uses conceivability to go right to metaphysical necessity while p-zombies shows a metaphysical possibility which undermines a metaphysical necessity, but I don't think this is the case. I think you're just showing a symmetrical inverse argument holds up with the same strength, which undermines Chalmers' use of conceivability as a guide to possibility in the first place. At 11:50 - I find this distinction confusing. What do you mean by "real"? Is it possible to expand on what you are thinking of in this aspect of your argument? I was under the impression that Keith thinks the appearance of phenomenal consciousness IS "real" in that the appearance is a real part of the physical structure and function of physical consciousness, but it is the ontological status of this appearance as a special, intrinsic property beyond the physical that is not real, which is what actually constitutes the illusion. I think this would line up with what you say here. Is this not the case? I know there are some forms of illusionism that do fully deny phenomenal consciousness, but I thought Keith's conception was different?
@onemorebrown
@onemorebrown Күн бұрын
Right, that is my point! We don't go straight to metaphysical necessity. We show that there is a possible work that undermines their metaphysical necessity! By 'real' I mean that it is not just an appearance. Phenomenal consciousness I mostly how we think it is (it is not an illusion)

@onemorebrown
@onemorebrown Күн бұрын
Dual Carving is Goff's name for the view that there may be two distinct concepts, each of which transparently reveals the essential nature of their referent, and which happen to pick out the same thing. So, in this case, there would be the concept of the physical state P, and the concept of the experiential state E. P would pick out the physical state by its essential nature and E would pick out the experiential state by its nature, and they would happen to be picking out the same thing. That they pick out the same thing would be something which could not be known a priori. You are right that he responded with this in our discussion, but my point was that there was no response in writing, in the literature. Informal discussions on YOuTube are not the same as a peer-reviewed article.

Robert Sapolsky’s claims of hard determinism are grounded in the idea that biology and neurological processes dictate human behavior, leaving no room for free will. However, the framework of Holistic Free Will (HFW) provides a compelling counterargument by integrating scientific evidence that demonstrates the capacity for reflection, adaptation, and growth within deterministic systems. For instance, neuroplasticity-the brain's ability to rewire itself-contradicts the deterministic notion that behavior is fixed. HFW highlights how practices like mindfulness meditation can reshape the prefrontal cortex, improving self-regulation and intentionality. Studies show that mindfulness enables individuals to interrupt automatic reactions, such as anger or impulsive behavior, and replace them with deliberate, value-driven choices. This capacity for neural restructuring aligns with HFW’s principle that individuals can navigate and transcend deterministic influences through reflective engagement with their biological and social conditions. Behavioral studies like Walter Mischel’s Marshmallow Test further illustrate HFW’s core principles. While initial self-control abilities in children were largely influenced by environmental and biological factors, the introduction of strategies such as distraction and reframing allowed them to significantly improve their capacity for delayed gratification. HFW emphasizes that these learned behaviors reflect the human ability to interact with deterministic conditions in ways that foster ethical growth and intentional change. Moreover, HFW integrates findings from rehabilitation science, where individuals recover from brain injuries or trauma by engaging in therapies that encourage neuroplasticity. Stroke patients, for example, often regain lost motor functions through intensive therapy that helps their brains form new neural connections. HFW reframes these recoveries as evidence of how structured realities-such as biological constraints-can be actively worked with and overcome through intentional effort, illustrating the dynamic interplay between determinism and autonomy. Through these examples, HFW bridges neuroscience and ethical philosophy, showing that while biology and environment significantly influence behavior, humans also possess tools for reflection, adaptation, and growth. Unlike Sapolsky’s hard determinism, HFW offers a nuanced understanding that respects deterministic realities while demonstrating how individuals can engage with and transcend them. This framework not only aligns with scientific evidence but also provides practical mechanisms for fostering autonomy and moral development within deterministic systems.

What a cross examination! Very interesting. I feel myself wanting you to have questioned his use of naive realism in his argument. If naive realism is true then consciousness really isn't a problem, and Matthias is using that to make it seem as though his view is uncontroversial (i agree with him that overflow is not an issue on naive realism, as any quality, like redness, sits comfortably - in a metaphysical sense - on surfaces or what have you, even if there existed no organisms at all in the entire world, and so qualities aren't even related to consciousness or conscious beings in that case). Problem is, of course, that naive realism is false - at any rate, Matthias isn't a naive realist. And his argument doesn't translate to any other physicalist view. On non naive realist physicalism, experienced qualities do not exist distally to the mind, thats the whole cunundrum. So if he says they exist in the brain then he is taking the exact same route as a first order theorist, and is open to the exact same criticism. Whether he thinks qualities are always conscious or not is irrelevant, because unconscious or not, they'd have to be identical to/grounded in brain states, just like a first order theorist claims. So his idea about consciousness being implicit belief/disposition to belief does no work. One might like that idea for independent reason, but the meat of his position is accepting intrinsic qualities (a view he apparently doesn't like).

Kind of disappointed that Goff didn't go for a more pantheistic/mystic recognition of awareness as divinity. Of nondual realisation as the recognition of God within. Certainly fits perfectly well within an idealist framework. (And, frankly, isn't tremendously far from a kind of atheism in a lot of ways.) But I guess he's traditionally avoided the idealist label-I guess because it really doesn't match how he feels.

That is a common assumption but it is not true. 'Either' serves, grammatically, to indicate that an 'or' is coming. It is useful in cases like 'either P and Q, or R' which lets you distinguish it from 'P and either Q or R'. I think you are right that a lot of English speakers use 'either' when they intend to communicate an exclusive or, but in logic we (almost) always take 'or' to mean inclusive or, whether there is an 'either' around or not. (I have a separate video on this that may interest you called 'propositional logic and Ordinary English' where I go into some of the details about the difference between pragmatics (what people mean when they say something) and semantics (what the sentences people say mean).
