All that needs to be borne in mind is that both vision and thought are information processing — TheMadFool
they don't have substantive existence — Janus
How different is mental info processing from that which takes place in the eyes when it sees something? No difference, in my humble opinion. — TheMadFool
So, if thoughts are not internally linguistically intoned they are like faint traces of cloud, or dimly sensed movements or visualizations; they seem to be anything but substantive. — Janus
That'd be why we have both senses and reason, no?What use is the brain without senses and what use are senses without a brain? What use is reasoning without anything to reason with or about? — Harry Hindu
You take the number under my name and you subtract the number under Baden's from it, and from that you arrive at the Baden sadness score. — Hanover
To be substantial is, to my way of thinking, to be an object of the five senses and their augmentations. — Janus
one decent enough answer to the thread title — Mww
don't see how reasoning could be separate from sensation. — Harry Hindu
By definition.science lights the way — DrOlsnesLea
, in this kind of sense there is the world of fashion, the world of football, the world of advertising, and so on; there are countless worlds in this sense, and they all have a different kind of existence. The important point though, relating back to the thread from which this thread was created, that these worlds do not have a substantive existence as the physical field of sense does — Janus
The ideal scientist has no such barriers. — DrOlsnesLea
From a lecture Karl Popper gave on the subject: — Olivier5
So, does the concept exist apart from the instances of it being thought? — Janus
If you keep telling me that your name is Olivier and I keep calling you Oliver or Amy then it won't surprise me if you get annoyed by it. — Michael
It could have been any city, or indeed any word. The point is, that although the representations all differ, they all mean the same. — Wayfarer
Do you think the name 'New York' exists apart from it's visual and auditory embodiments? — Janus
Misgendering is cruel — K Turner
This discussion was created with comments split from Substance Dualism Versus Property Dualism Debate Discussion Thread — Hanover
It's normal to be drawn to that which is like you — Lil
It also requires the ability to abstract, to understand symbolic meaning, as you keep pointing out. — Wayfarer
What would that be? The idea that scientific theories exist?Why not simply scientific realism? — DrOlsnesLea
I now come to the discussion of my central problem. Are world 3 objects, such as Newton’s or Einstein’s theories of gravitation, real objects? Or are they mere fictions, as both the materialist monist and the dualist assert? Are these theories themselves unreal, and only their embodiments real, as the materialist monist would say; including, of course, their embodiments in our brains, and in our verbal behaviour? Or are, as the dualist would say, not only these embodiments real, but also our thought experiences; our thoughts, directed towards these fictitious world 3 objects, but not these world 3 objects themselves?
My answer to this problem -- and, indeed, the central thesis of my talk -- is that world 3 objects are real; real in a sense very much like the sense in which the physicalist would call physical forces, and fields of forces, real, or really existing. However, this realist answer of mine has to be defended, by rational arguments.
There is perhaps a danger here that my central problem, the reality or existence of world 3 objects, may degenerate into a verbal issue. After all, we can call whatever we like ‘real’ or ‘existent.’ I think that we can get rid of this danger, by starting from the most primitive idea of reality, and by adopting the physicalist’s own method of generalizing this idea, and, ultimately, of replacing it altogether.
I suggest that all of us are most certain of the existence or reality of physical bodies of medium size: of a size such that we can easily handle them, turn them round, and drop them. Such things are ‘real’ in the most primitive sense of the word. I conjecture that a baby learns to distinguish such things; and I suppose that those things are most convincingly real to the baby that he or she can handle and drop, and can put into his or her mouth. Resistance to touch also seems to be important; and some degree of temporal persistence.
Starting from a primitive idea of real things like this, the
physicalist extends the idea by generalizing it. I suggest that the materialist’s or physicalist’s idea of real physical existence is obtained by including very big things and very small things, and things that do not persist through any length of time; and also by including whatever can causally act upon things, such as magnetic and electrical attraction and repulsion, and fields of forces; and radiation, for example X-rays, because they can causally act upon bodies, say, upon photographic plates.
We are thus led to the following idea: what is real or what exists is whatever may, directly or indirectly, have a causal effect upon physical things, and especially upon those primitive physical things that can be easily handled.
Thus we may replace our central problem of whether abstract world 3 objects such as Newton’s or Einstein’s theories of gravitation have a real existence, by the following problem: can scientific conjectures or theories exert, in a direct or indirect way, a causal effect upon the physical things of world 1? My reply to this question will be: yes, they can indeed.
My fundamental argument in support of world 3 [ideas] realism is very simple. We all know that we live in a physical world 1 which has been greatly changed by making use of science; that is to say, by using world 3 conjectures or theories as instruments of change. Therefore, scientific conjectures or theories can exert a causal or an instrumental effect upon physical things; far more so than, say, screwdrivers or scissors.
I see those seven differently type-faced examples of 'New York' as sharing a common recognizable pattern, and hence being identifiable as signifying the same thing, not as representing some changeless disembodied name. — Janus
Horse noun

plural horses also horse
Definition:
1a: Anything that looks sufficiently like a horse. — Olivier5
The traditional distinction in philosophy is between reason and sensation - both central to knowledge, but separate faculties. — Wayfarer
It's not a seeming contradiction. There definitely are multiple, slightly different 'A's. Hopefully no one is mad enough to dispute that. Here's one A, and here's another A, looking the same, but in a different location and microscopically different on your screen. There's also, categorically, multiple, slightly different concepts of A, some people might have different criteria to others and even for themselves in different contexts at different times in their life.
None of the above applies to universals, which are a posited philosophical entity which may or may not exist. — Isaac
If there can be one city that is never the same from moment to moment why can a number not be the same, in the sense of not being changeless, while being perfectly capable of being referred to by a name? — Janus
Any examples of what these additional senses are, over and above the five we're taught at school? — Wayfarer
