If it could happen without “magic”, that would mean it was something that could be built up from non-conscious processes, and so would not be whatever the supposed difference is between a philosophical zombie and a real person. — Pfhorrest
Phenomenal consciousness is defined in opposition to that kind of process. Nothing that the ordinary mechanical properties of matter can build up to, including the full complex and nuanced behavior of a human being, can constitute phenomenal consciousness by itself, as it is defined by the people who came up with the idea. — Pfhorrest

some arbitrary line somewhere, the line between things that are held to be entirely without anything at all like phenomenal consciousness and things that suddenly have it in full, — Pfhorrest
Conclusion: it's not possible for us to gain or obtain knowledge about anything that goes beyond our senses, memory and testimony. — Humelover
But here it may be proper to remark, that though our conclusions from experience carry us beyond our memory and senses, and assure us of matters of fact which happened in the most distant places and most remote ages, yet [...]
In a word, if we proceed not upon some fact, present to the memory or senses, our reasonings would be merely hypothetical; and however the particular links might be connected with each other, the whole chain of inferences :wink: would have nothing to support it, nor could we ever, by its means, arrive at the knowledge of any real existence. — Hume, Enquiry, section 37
Had not the presence of an object, instantly excited the idea of those objects, commonly conjoined with it, all our knowledge must have been limited to the narrow sphere of our memory and senses; — 44
Hence likewise the benefit of that experience, acquired by long life and a variety of business and company, in order to instruct us in the principles of human nature, and regulate our future conduct, as well as speculation. By means of this guide, we mount up to the knowledge of men’s inclinations and motives, from their actions, expressions, and even gestures; and again descend to the interpretation of their actions from our knowledge of their motives and inclinations. — 65
The bad science part is to assume that it's simple. For instance, there is probably some genetic basis for character traits, but there's no one-to-one relationship between genes and character traits. "The genes of love" or "the genes of selfishness" are gross simplifications of far more complex realities. — Olivier5
The bogey of genetic determinism needs to be laid to rest. The discovery of a so-called ‘gay gene’ is as good an opportunity as we'll get to lay it.
[...]
Genes, in different aspects of their behaviour, are sometimes like blueprints and sometimes like recipes. It is important to keep the two aspects separate. Genes are digital, textual information, and they retain their hard, textual integrity as they change partners down the generations. Chromosomes — long strings of genes — are formally just like long computer tapes. When a portion of genetic tape is read in a cell, the first thing that happens to the information is that it is translated from one code to another: from the DNA code to a related code that dictates the exact shape of a protein molecule. So far, the gene behaves like a blueprint. There really is a one-to-one mapping between bits of gene and bits of protein, and it really is deterministic.
It is in the next step of the process — the development of a whole body and its psychological predispositions — that things start to get more complicated and recipe-like. There is seldom a simple one-to-one mapping between particular genes and ‘bits’ of body. Rather, there is a mapping between genes and rates at which processes happen during embryonic development. The eventual effects on bodies and their behaviour are often multifarious and hard to unravel.
The recipe is a good metaphor but, as an even better one, think of the body as a blanket, suspended from the ceiling by 100,000 rubber bands, all tangled and twisted around one another. The shape of the blanket — the body — is determined by the tensions of all these rubber bands taken together. Some of the rubber bands represent genes, others {105} environmental factors. A change in a particular gene corresponds to a lengthening or shortening of one particular rubber band. But any one rubber band is linked to the blanket only indirectly via countless connections amid the welter of other rubber bands. If you cut one rubber band, or tighten it, there will be a distributed shift in tensions, and the effect on the shape of the blanket will be complex and hard to predict.
[...]
So, if you hate homosexuals or love them, if you want to lock them up or ‘cure’ them, your reasons had better have nothing to do with genes.

Why are you pestering this thread — Srap Tasmaner
You called reference a fantasy; — Srap Tasmaner
but of course it turns out this is a picturesque way of describing anything abstract — Srap Tasmaner
What's the intended force of this though? — Srap Tasmaner
Are you distinguishing reference from something we do with language that is not a fantasy? — Srap Tasmaner
If you aren't, why should we care? — Srap Tasmaner

It's not a convention that what one says by way of a statement is an assertion; if it were, the turnstile would add something to the utterance. — Banno

A visual map can be encoded in binary on a computer, and a human could read off those ones and zeros, even if they didn’t understand what they were reading. All the information in the picture would be retained in the sound of the human voice.
— Pfhorrest
So this seems to me an excellent example of the obvious differences to be found between an object (whatever it was, a still life?) and its representation or description (the vocalised bit map). The map is certainly not the territory.
If that picture were to be perfectly detailed down to the subatomic level, it would have to be animated
— Pfhorrest
If you mean represent temporally successive states, gradients etc. then, sure. If you mean represent them by a temporal succession of symbols, then surely not? Why? (I know the bit map is vocalised as a succession, but thus far that aspect was irrelevant to what it described, and could continue to be so, I would have assumed.)
or at least include temporal information in it like momentum, and all of the structural details that give a complete picture of its function,
— Pfhorrest
Sure, why not. We're on a flight of fancy as regards the level of precision achieved by the description, but that's ok. Bolt on another hard drive (or immortal chanter) to store the whole bit-map.
and contain within it all the exact information that the physical thing the “picture” it is of does.
— Pfhorrest
(Interesting syntax... reminds me of "no head injury is too trivial to be ignored" ;) )
Do you mean, "the physical thing that the picture is (a picture) of: the thing it depicts; the bowl of fruit?
Ok, the picture/bit-map/description must be as complex as the physics of a bowl of fruit; but was this paragraph meant to show how the bit-map must become a replica of the bowl of fruit? That's what I'm not getting. — bongo fury
Talking about a literal map of a city is probably a clearer illustration. — Pfhorrest
Yes? When was the last time you saw a yurg? — tim wood
No yurgs are green, or, all yurgs are blue, on the other hand, cannot be presumed to imply there are any yurgs. — tim wood
you would have them as proof of the existence of yurgs. — tim wood
if the false proposition were that no yurgs were not dinosaurs, then you're in the position of affirming the existence of yurgs. — tim wood
But the configuration of prefixes '~∀x~' figures so prominently in subsequent developments that it is convenient to adopt a condensed notation for it; the customary one is '∃x', which we may read 'there is something that'.

the argument itself does not grant people. — tim wood
It's intended to reinforce the argument that the question drops out of any relevance. — Banno
Or, to switch examples, even if you and I don't mean the very same colour when we say "red" - if your red is my blue - — Banno
So this is the question:
If Alice is thinking something, must we conclude there is something that Alice is thinking? — Srap Tasmaner
But true sentences can correspond only to made-upabstractionschimaeras. — bongo fury
Truth is not correspondence to reality. Why? — Dfpolis
Or, to switch examples, even if you and I don't mean the very same colour when we say "red" - if your red is my blue - we will both stop at the red light. — Banno
Is it just me, or oughtn't everyone here (and on similar threads) to clarify which of these two related but separable questions they are addressing?
• is my external red the same as your external red?
• is my internal red the same as your internal red? — bongo fury
A place where we see a more trivial side of ontological relativity is in the case of a finite universe of named objects. Here there is no occasion for quantification, except as an inessential abbreviation; for we can expand quantifications into finite conjunctions and alternations. Variables thus disappear, and with them the question of a universe of values of variables. And the very distinction between names and other signs lapses in turn, since the mark of a name is its admissibility in positions of variables. Ontology thus is emphatically meaningless for a finite theory of named objects, considered in and of itself. Yet we are now talking meaningfully of such finite ontologies. We are able to do so precisely because we are talking, however vaguely and implicitly, within a broader containing theory. What the objects of the finite theory are, makes sense only as a statement of the background theory in its own referential idiom. The answer to the question depends on the background theory, the finite foreground theory, and, of course, the particular manner in which we choose to translate or imbed the one in the other. — Quine: Ontological Relativity
The only tenable attitude toward quantifiers and other notations of modern logic is to construe them always, in all contexts, as timeless. — Quine: Mr Strawson
As you like, it's just that math never uses quantifiers that range over even all mathematical objects, — Srap Tasmaner
The existential proposition can be expressed with bounded quantification as
∃x∈D P(x)
or equivalently
∃x (x∈D & P(x)) — Wikipedia
A [..] natural way to restrict the domain of discourse uses guarded quantification. For example, the guarded quantification
