Most of metaphysics is word play. — Banno
What is the purpose of saying "The pen is red"? Why is that useful to say? — Harry Hindu
Does a red apple and red pen have the same constitution? Could we mean more than one thing in saying "the apple is red" vs. "the pen is red"? — Harry Hindu
- define... so what, setting out essence-of-pen? "Comprised" of redness? Nothing so sophisticated. Just one red pen amongst others, red and not so red. — Banno
Then if you also think that there is no such thing as internal red, we might well agree. — Banno
In other words, stop trying to be God and be happy with your lot as a tiny human, with limited understanding. — frank
The human viewpoint is that gravity did it. The view beyond human ideas is not available to me. — frank
He is talking about the field of physics, not the laws of physics. — Lionino
No, you need language for physics, don't you? — frank
Language sets out the whole framework of physics. — frank
But the pen looks red to me, too. And given the right filter we might make the red pen look blue... which pen? The red pen. The red pen looks blue. Not Hanover's "The pen that looks red to me looks blue to me". — Banno
Ok. So for Hanover, "the pen is red" is not true. I think it is. — Banno
And yet we agree that the pen is red. — Banno
I'm guessing you're like me. — frank
Language plays a very important role in everything you experience. — frank
Thanks for the effort that you put into your post but I can't connect your reply to the example I brought up in my post, I agree that subjective consistency doesn't suggest objective existence but I feel like my example wasn't really addressed. — Lionino
However, if someone sees and feels a round object where someone else sees and feels a square one, and the square-person told the round-person to grab the object by the edges, wouldn't the round-person be bewildered? Surely, when a square-person says corner the round-person would think of a round object, but the round-person can't think of anywhere special in that object (any given point on the surface of a sphere is the same). — Lionino
This is Hume's phenomenalism, and I agree with it. There's nothing in the visual field that says: tree. Tree is an idea. — frank
But you just did with pain? You accept that pain is a mental percept. Presumably you accept that trees are not a mental percept? — Michael
Do you believe that pain is a mental percept or a mind-independent property of distal objects? — Michael
Some things, like pain, are in the head. Other things, like trees, are not. — Michael
you have a red pen in your hand, you can pass the red pen to me. If you have a pain in your hand, you cannot pass the pain to me.
The analogy between pain and colour fails because there is a public aspect to colour that it not available for pain. — Banno
So to make this simple, here are two sets of claims:
Naive realism
1. Our ordinary conception of colours is that of sui generis, simple, intrinsic, qualitative, non-relational, non-reducible properties.
2. These sui generis properties are mind-independent.
Dispositionalism
3. Our ordinary conception of colours is that of micro-structural properties or reflectances.
4. These micro-structural properties are mind-independent.
I agree with (1) and (4) and disagree with (2) and (3). — Michael
I didn't enter this discussion to question scientific realism and argue for idealism or solipsism or nihilism. I am simply explaining what the science shows. I trust the science. — Michael
Your argument seems to be that if I claim that colours are mind-dependent then to be consistent I must claim that everything is mind-dependent. This is nonsensical reasoning. You might as well argue that if I claim that pain is mind-dependent then to be consistent I must claim that everything is mind-dependent. — Michael
↪Michael I'll have to think about this for a while.

Atoms are mind-independent objects with mind-independent properties; their electrons absorb and re-emit various wavelengths of light, this light stimulates the rods and cones in the eyes, the eyes send signals to the brain, the neurons in the visual cortex are activated, giving rise to visual percepts, including colour percepts. — Michael
How do we perceive a fire’s propensity to cause pain? By putting our hand in the fire and being hurt. In the case of colour, we look at the pen and see red. — Michael
I think it’s a little more than an assumption. Perhaps it’s the most rationally justified explanation. — Michael
Except that the concept of a mind independent chair is incoherent. The only thing I know about chairs are its subjectively imposed properties, and so I have no idea what a true chair is.I think it’s justified to claim that mind-independent chairs exist but that mind-independent pain doesn’t, and most would agree. — Michael
How do we perceive this propensity? Do we just assume our perceptions are externally caused?The existence of its atoms and their propensity to reflect light at certain wavelengths. — Michael
I can be sure that there's red and that there's pain, but given our scientific understanding of physics and biology and psychology, it seems to be that red and pain are properties of minds, not properties of pens and fire.
The issue isn't over whether or not these properties exist, but over where in the world these properties exist. At least when it comes to colour, some appear to be locating them in the wrong place. — Michael
Still for brevity’s sake, I reach the conclusion sans argument that while books are to be read, they are also to be challenged, and once challenged and the challenges disposed of, to be set aside or even discarded in favour of the business of living a life. I leave it to the discussion to settle what books this applies to, whether all, some, or none, or what types. — tim wood
Colours are biological phenomena that arise when we and many other organisms interact with our visible environment. — jkop
I'm sure there's red. Do you know of a good reason to doubt colour realism? — jkop
There's little reason to doubt the existence of a spectrum of electromagnetic radiation that we by convention label 'red' . — jkop
Even in deciding not to run, Joe Biden did something Trump could never do - which was to put the interests of the Party and the nation above his own.
I’m not particularly swayed by the euphoria sorrounding Harris today. Let’s see how it plays out over the weeks and months ahead (although there’s not that many of them.) I think it is true to say that it’s the politics of hope against the politics of hate and fear. — Wayfarer
Yup! More platitudes.
So my conclusion for this topic is -- we don't have an answer. Nothing. Rien.
Morality is a chore. — L'éléphant
Yea, but that's child's play compared to the way the Republican party has gerrymandered North Carolina. So the attack on the Capitol where they appeared to be prepared to freakin execute the Vice President is like infant's play. Like with a rattle or something. — frank
I'm not seeing anything criminal in Dems pursuing legal challenges. — RogueAI
