But there's a physical connection between our brain activity (which is us thinking about the Sun) and things that aren't the Sun. — Michael
And, again, we can (presumably) think about things to which brain activity doesn't have a physical connection, e.g. future, past, and distant events. — Michael
Why isn't there a physical connection to things in time or space? — Marchesk
The sun isn't inside our brains. It's several million miles away, and 8 minutes old by the time we see it. But we talk about it, study it, predict it, explain it, etc.
But not according to anyone else? The sun is just an experience that has nothing to do with our talk of the sun? That sounds rather Landru-like, and it was one of the least convincing things he ever argued for.
That's the very thing I'm questioning. What kind of connection is there between our brain activity (and our vocalisations and writings) and some other physical thing millions of miles away such that the former is a thought (or a statement) about the latter? It seems to me that if no sensible account of this reference-connection can be made then the very realist claim that we talk and think about things which are ontologically independent of our thoughts and speech is an incoherent one. — Michael
he first two because (unless eternalism is true) past and future things don't exist, and the last because of special relativity (i.e. the light cone). — Michael
Does it make any difference if it's 5 feet away versus 5 million miles (I don't recall the sun's distance from Earth). Light takes time to travel regardless. Talking about a tree, a star, tea in China, it all takes time to get to us. — Marchesk
They did, or will exist, and GR suggests that they do.
t doesn't matter if it's 5 or 5 million feet away. What is the connection between brain activity and some other physical thing such that the former is a thought about the latter? — Michael
To express the general form is not to express the "perfect form". That is a mistake. It is to express what each and every one of the particulars has in common. — Metaphysician Undercover
You will not understand what "triangle" means from that visual representation, or even a number of them, you will have to refer to the definition. — Metaphysician Undercover
From a drawing of any triangle, I can see immediately that it has three straight sides and three angles; and that is precisely the definition of a triangle. — John
No actual drawing of a triangle has three perfectly straight sides and exactly three angles, as required by the definition. — aletheist
A vague representation cannot adequately express the general characteristics of a form, certainly not of a complex form. — John
That drawing is not a representation of any particular maple leaf but of the idealized general form of the maple leaf. — John
The fact that the actual marks on the screen or paper have thickness or that the precise proportions of the general form are not shown is irrelevant. — John
... such visual representations allow us to sharpen up those vague implicit understandings and make then more explicit. — John
Do you agree that representations stand for or refer to something other than themselves? — Terrapin Station
So what's the nature of the special kind of relationship between marks on paper and some other thing such that the former represents the latter? Is it a physical relationship? Is there a special chain of atoms that connects the ink to something else (and only that something else)? — Michael
I'd say that the relationship is a conceptual one (i.e. we have a particular kind of cognitive attitude towards the ink), which is why it can't exist outside of people's heads. — Michael
It depends on what you mean by "adequately." In a sense, no particular representation can adequately express the general characteristics of any form, simple or complex. — aletheist
Only because we understand it to be so, in light of the purpose of the representation. If that drawing was instead intended to show how a specified hue is rendered on a computer monitor, then the color of the line would be the only relevant aspect. — aletheist
My argument with MU was actually over his assertion that there is a general form which is temporally prior to the advent of any particular form. — John
Yes I agree, that is the nature of a representation. — Metaphysician Undercover
Okay, so how, outside of someone thinking about it this way, does a set of marks on paper or a piece of metal or whatever stand for or refer to something other than itself? — Terrapin Station
All that "each and every one has in common" is that they approximate the perfect (that is ideal) form. — John
No, that's plainly wrong. From a drawing of any triangle, I can see immediately that it has three straight sides and three angles; and that is precisely the definition of a triangle. — John
My argument with MU was actually over his assertion that there is a general form which is temporally prior to the advent of any particular form. — John
What about logically prior? I would suggest that a general form is a continuum of potential forms, and a particular form is an actualization of one such possibility. — aletheist
Well clearly, this is where we differ. I don't believe in the perfect, or ideal maple leaf. I don't think there is any such thing. I believe that the general form of the maple leaf is the things which they all have in common, a stem, veins, a specific number of points, and growing on a maple tree. — Metaphysician Undercover
That is the problem, you cannot, as you claim here, infer the general from an instance of the particular. — Metaphysician Undercover
This is inferred from the fact that an object must have a particular form. And when the object comes into existence, as the object which it is, it must be predetermined what it will be, or else it will not come into existence as that object, or as any object at all (because every object is a particular object). — Metaphysician Undercover
Through the relationship which was established by the one who made the marks. — Metaphysician Undercover
In your category of "someone" do you include God? — John
Apart from that consideration; did undiscovered textual artifacts stand for or refer to anything during the period that no one knew about them?
The perfect form is just the idealized form, which is the same as the general form. Not just maple leaves have stems and veins. Another kind of leaf may have the same specific number of points, too; it is the averaged configuration of those points and the average length of the edges that join them that count as the general form. Growing on a maple tree is not a general form it is an attribute or associative definition. — John
I have no idea why you purport that an object cannot come into existence without their being a (presumably) pre-existent general form which predetermines it to be what it is. What evidence could you possibly have for that claim.? What could such a "pre-existence" look like? — John
Let me try once again, to explain this issue. As time passes, there is as you say, "a succession of slightly different forms". At each moment of the present, the maple leaf is this particular maple leaf, it is not that particular maple leaf which it was at the last moment, because it has changed. Therefore at each moment the maple leaf is a new, and different object. So at each moment a new object is created, we can call them MLt1, MLt2, MLt3, etc., each collection of symbols referring to a different object. Let's take MLt3 for example. When that object comes into existence, it necessarily comes into existence as the object which it is, MLt3, or else it is not MLt3. It does not come into existence as MLt2, Mlt4, or any random thing, it comes into existence as MLt3. Therefore we can assume that there is a cause of its existence as MLt3, a reason why it exists at that moment as MLt3, and not something else. This is the determining form of MLt3. Notice that in order for the object, MLt3, to exist at that present moment, as MLt3, it is necessary that the form of MLt3 existed prior to that. This prior form is not MLt2, it is not MLt4, because these are distinctly different. It is nothing other than the form of MLt3, which exists prior to the object MLt3, and ensures that object MLt3 will exist as that object, at that moment in time. — Metaphysician Undercover
