           | That isn't the witty riposte that it is apparently thought to
           | be. It really does "explain away" consciousness by reducing
           | it to plausible physical processes. This reduction also
           | applies to things like qualia, which is where nonmaterialists
           | get upset as qualia (or equivalents) are also invoked by
           | people like Nagel and Chalmers to argue against the
           | physicality of consciousness.
           | 
           | The core argument from Nagel / Chalmers is that that there is
           | a subjective element to consciousness which has no physical
           | explanation. The reasoning for this is always an appeal to
           | intuition. If you accept that there is "something that it is
           | like" to see red, be a bat, etc, and that the "something that
           | it is like" is above and beyond the physical processes of the
           | brain -- the firing of neurons -- then you by definition
           | cannot accept a purely physical explanation of consciousness.
           | Dennett's book argues that this is mystical nonsense (or,
           | charitably, wishful thinking) and the "something that it is
           | like" is simply what happens when particular types of
           | physical processes occur in the brain.
           | 
           | It's no surprise, therefore, that "explained away" is a
           | criticism if you're a nonmaterialist. But if you're a
           | materialist, then "explained away" is actually a good thing
           | and the purpose of the book.

             | these being separate and distinct processes, yet
             | materialists claim they are the same and identical process.
             | Qualia isn't the same process as the physical processes in
             | the brain; they are very highly correlated, but ultimately
             | distinctly separate processes.

               | I put the concept of "philosophical zombies" as quackery.
               | At best, the p-zombie thought experiment shows that we
               | haven't really come up with a definition of consciousness
               | that explains what we want it to explain. Some people use
               | p-zombies as part of a larger argument against
               | physicalism. Chalmers published a modal logic argument
               | against physicalism using p-zombies. One of the tricky
               | things about modal logic is that it requires a deeper
               | understanding of modal logic in order for you (you,
               | someone reading a modal logic argument) to make good
               | decisions about which propositions you are willing to
               | accept in a modal logic argument. Since most people only
               | have an intuitive understanding of modal logic, it is a
               | good way to win an argument but a bad way to explain your
               | position.
               | 
               | I'd say that this work (p-zombies) is quackery in the
               | sense that it's consistently directed at something which
               | I consider to be unproductive, which is the work of
               | undermining or attacking physicalism / physical monism.
               | At some point, in these discussions, you end up having
               | some argument about the semantics of ontology and how you
               | define "existence". If your semantics for "existence"
               | admits non-physical things to exist (like, if you're a
               | Platonist), and you're having a conversation with someone
               | who believes in physicalism, then I don't think either
               | person in the conversation is going to get much out of
               | it, other than a better way to explain their own
               | position.
               | 
               | Edit: I hope that paints a complete enough picture and
               | covers the important parts of my complaints about
               | p-zombies. I don't have my finger on the pulse of
               | philosophy and I may be missing something important,
               | maybe there's some really important argument p-zombies
               | are used for, and maybe I don't understand Chalmers;
               | that's always a risk. My main complaint here is that it
               | seems to be some tool to make an argument against
               | physicalism, but this tool doesn't help you understand
               | physicalism, or help you understand its alternatives.
               | It's just an argument that you can have between somebody
               | who believes in physicalism and somebody who doesn't,
               | where neither person will agree with the other one after
               | hearing the argument.

               | Oh, here's the thing--it's not actually important to
               | argue about what the word "quackery" means. I've
               | explained what I meant by "philosophical quackery", and
               | if you want to talk about the content of what I wrote,
               | then by all means, respond to the content.
               |

               | 
               | I'm not sure what else there is to say here. If you call

               | 
               | "Quackery" is not some technical term here. It is a

               | 
               | I could also insert some comment about the history of
               | philosophy and modernism / post-modernism, here. If you
               | take the stance that a word means something
               | independently, in some kind of platonic sense, then you
               | agree with the modernists. If you take the stance that a
               | word's meaning comes from how it's interpreted by people
               | who read it, you agree with the post-modernists.
               | 
               | I'm just trying to use a word to convey some sort of
               | meaning. If that word didn't convey the intended meaning

               | 
               | Terms are generally used unclearly, it is unavoidable.
               | When I say that "I don't want to argue about
               | definitions", what I mean is that I want to talk about
               | subject X, and I used the word "quackery" to describe it.
               | I want to talk about subject X, not about the definition
               | of "quackery", which is irrelevant.
               | 
               | A discussion about the word "quackery" is immaterial
               | because I can clarify things by re-explaining subject X
               | using different words. I did that--but apparently you are
               | not interested in clarifications, because your actions
               | indicate a greater interest in fighting over whether I
               | used the word "quackery" correctly.

               | stuff. The Tractatus built on the work of Frege and was
               | incredibly dense in its logical expressions, and half the

               | Plato's ideal forms find their match in HTML. Much like
               | Plato's theory, where objects in the physical realm are
               | mere shadows of their perfect forms, HTML is but the

               | on the more material CSS and JavaScript to breathe life
               | into its skeletal outlines. HTML, the philosopher of the
               | web, contemplates the essence of web structure in a cave
               | of its own making, illuminated by the flickering screens
               | of web developers trying to decode the shadows of their
               | CSS frameworks.
               | 
               | Aristotle: _Python_
               | 
               | Aristotle, known for his logic and systematic approach to
               | the physical world, would be Python. Just as Aristotle
               | classified flora and fauna, Python organizes data with
               | lists, tuples, and dictionaries, making it ideal for
               | developers who seek clarity and readability. Python's
               | philosophy is simple yet profound, mirroring Aristotle's
               | quest for understanding through empirical observation and
               | not-so-metaphysical methods.
               | 
               | Descartes: _C++_
               | 
               | "I think, therefore I am," proclaimed Descartes, and so
               | would any program written in C++. C++, with its complex
               | syntax and powerful capabilities, reflects Descartes'
               | dualism. It can create almost metaphysical experiences in
               | virtual realities but can also cause existential crises
               | with its pointers and memory leaks, leading programmers
               | to doubt everything, especially their choice of language.
               | 
               | Nietzsche: _Assembly_
               | 
               | Nietzsche, the philosopher of power, will to manifest,
               | and the ubermensch, resonates with Assembly language. Not
               | for the faint-hearted, Assembly is for those who dare to
               | manipulate the very fabric of hardware. Like Nietzsche's
               | writing, Assembly is tough to decipher, powerful in its
               | capacity, and not commonly understood by the masses,
               | often leaving one to ponder in solitude about the eternal
               | recurrence of debugging sessions.
               | 
               | Kant: _Java_
               | 
               | Kant, who was all about rules and categorical
               | imperatives, fits perfectly with Java. Java's platform-
               | independent mantra--write once, run anywhere--is a stern
               | dictate akin to Kant's moral imperatives. Both
               | philosopher and language demand strict adherence to their
               | defined structures and frameworks, leaving little room
               | for moral or syntactic error.
               | 
               | Sartre: _JavaScript_
               | 
               | Existentialist par excellence, Sartre's notion of
               | existence precedes essence is the lived reality of every
               | JavaScript framework. Just when you think you understand
               | the essence of the JavaScript ecosystem, a new library or
               | framework pops into existence, challenging the very core
               | of your understanding. Sartre's philosophy of radical
               | freedom and existential angst mirrors the liberty and
               | chaos of JavaScript's untyped, loosely structured syntax.
               | 
               | Hegel: _Haskell_
               | 
               | Hegel's dialectical method moves through thesis,

               | approaches problems with its pure functional programming

               | Since we're talking about contingency...
               | 
               | I'll just lay out a version of the argument from
               | contingency:
               | 
               | 1. A contingent being (a being such that if it exists, it
               | could have not-existed) exists.
               | 
               | 2. All contingent beings have a sufficient cause of or
               | fully adequate explanation for their existence.
               | 
               | 3. The sufficient cause of or fully adequate explanation
               | for the existence of contingent beings is something other
               | than the contingent being itself.
               | 
               | 4. The sufficient cause of or fully adequate explanation
               | for the existence of contingent beings must either be
               | solely other contingent beings or include a non-
               | contingent (necessary) being.
               | 
               | 5. Contingent beings alone cannot provide a sufficient
               | cause of or fully adequate explanation for the existence
               | of contingent beings.
               | 
               | 6. Therefore, what sufficiently causes or fully
               | adequately explains the existence of contingent beings
               | must include a non-contingent (necessary) being.
               | 
               | 7. Therefore, a necessary being (a being such that if it
               | exists, it cannot not-exist) exists.
               | 
               | 8. The universe, which is composed of only contingent
               | beings, is contingent.
               | 
               | 9. Therefore, the necessary being is something other than
               | the universe.

               | experiments in dreams. That is one of the things that

               | You can never prove that. You might be living in the
               | Matrix, and the Matrix could be controlled by an evil
               | demon. That possibility can never be completely

               | explain observations, and so they can be discounted for

               | things like science as a whole. Science is more
               | traditionally IMO considered to be a recursive process
               | with rational (i.e. theory) and empirical (i.e. sense
               | data) steps. In science, sense data provides a constraint
               | on theory and theory (together with psychology) provide a
               | constraint on the raw sense data (in the same way, for
               | example, an AI provides structure to the raw input
               | vectors).
               | 
               | If that's something along the lines of what you believe,

               | actually in disagreement.
               | 
               | But I wouldn't describe that belief system as saying
               | empricism is self-justifying. Empiricism in practice goes
               | off the rails pretty quickly with things like subjective
               | idealism and the belief that there are no external
               | entities, only sense data etc.
               | 
               | The thing we have now, where theory and experience
               | mutually constrain each other seems obviously correct to
               | me both in the academic sense (e.g. I think that Kant was

               | data). I also think it's true in the broader sense (e.g.
               | that the applied sciences tend to move more slowly on
               | their own and advance much more rapidly when combined
               | with theory).

               | them_ as necessary conditions that are prior to nature.
               | It would be harder (but not impossible!) to entertain if
               | there was daylight between what we believed our faculties
               | to be and what we believed the natural world to be, if

               | world really is.
               | 
               | Second, for a different way of stating a similar point,
               | if time and space are non-newtonian in some important
               | way, we may have to understand that _that_ is what we
               | experience in the first instance, and we would have to
               | wrestle with the fact that our intuitions may attest to a
               | variety of possible underlying necessary conditions.
               | (Wittgenstein has been mentioned in this thread, so for a
               | paraphrase of something he supposedly said, in reply to a

               | earth:  "What would it look like if the earth went around
               | the sun?" So it may be with the nature of our faculties.)
               | 
               | Third, as we gain deeper understanding of brain functions
               | of ourselves and other creatures, we may have inroads to
               | how certain of our conscious experiences depend on
               | conceptual abstractions or models. And if so, it

               | consciousness _does_ exist, but it is not like what many
               | people think it is like. It does not have all of the
               | properties that many people think it has. He _does_ say
               | that things with _those_ properties don 't exist--because

               | _not_ say that consciousness does not exist--just that it
               | doesn 't have those properties.

               |  _> the apparent total denial of experience_
               | 
               | He doesn't say this either, although many of his
               | opponents misdescribe him as saying that--because they
               | cannot understand what he is actually saying. The only
               | concept of consciousness they can grasp is the magical
               | concept they have in their heads--I call it "magical"
               | because it cannot exist if consciousness is a physical
               | process working according to physical laws. And the
               | latter kind of consciousness, the physicalist kind, is
               | the kind Dennett describes and the kind he believed
               | existed. So for opponents of his who can't even grasp
               | that there _is_ such a concept of consciousness, the only
               | way they could interpret what Dennett was saying was that
               | he was denying that consciousness existed.
               | 
               | But that is a gross misrepresentation of his views: he
               | was _not_ saying that people don 't have experiences or
               | thoughts. He was just saying that those real things, when
               | you actually do the hard work of figuring out _how_ they
               | work in accordance with physical laws, turn out not to
               | have some of the properties that people thought they had
               | before that hard work was done. This is no different from
               | any other concept once we try to build an actual
               | scientific understanding of it.
