This debate reminds me of the technical hair-splitting of medieval schoolmen.
I do think that just as perceptions give rise to some very primitive concepts, like yellow. Higher, more abstract, concepts, like equity, often give rise to perceptions.
And I agree with Tywvel that IF we consider black and white to be opposites, then each implies the other and cannot exist as a meaning without it.

I.


I like to say 2 things...1...Good work Joe.
2...as I mentioned, I believe that the OP was in relation to certainty*, as such, determing that certainty is possible, is very desirable.

*certainty means know enough to be sure, doesn't mean immutable,.... and it can be compromised by reasonable doubt, although I've not heard anything that makes me doubt my certainty of what white is.

Sorry to beat a dead horse and drag it out, but I'm bored...

Such an argument is only as good as the authority. In the case of philosophical disputes, however, the dictionary is no more authoritative than any other source. You need to demonstrate why the dictionary definition is preferable to any other.
What other authority are you interested in comparing it to?
Haven't found any others mentioned here so far, but I'm always open to suggestions.

Please demonstrate why.

A more concrete example: On a computer screen you can display a mid-level gray color (#808080).

This actually is another type of argument ad verecundiam: in this case, the authority is the computer monitor. Presumably, this unimpeachable source can give us an unambiguous "grey," but it somehow is incapable of providing us with an equally unambiguous "white" or "black."
You presume incorrectly. My point involved no authority at all, simply presenting one example that hopefully you could grasp. Use a random source of gray light. Anything gray will do, especially if you drop the "authority" straw-man from it.

But if you place it next to a bright halogen lightbulb, then it looks like the screen is turned off and is completely black.
The same image, on the same monitor, giving off the same color and amount of light, is seen as white and also as black.

And your point is?
To simplify: This object can be considered both "white" and "black".
We're discussing how black and white are the same.
I provided an example of such, and hopefully you will consider it.

As any painter can tell you, it's the contrast that makes white appear white, or black appear black.

This is merely apparent color. Are you suggesting, then, that there are "true" colors?
Nope.

I challenge you to find anything in the world that you believe is "white". Then stare directly into the sun or an electric arc lamp, and see if you still believe your item is "white". No matter what white thing you find, you can find something else that's whiter. It's relative. Nothing is absolutely white.

I look at a tree from a distance of 100 yards. To me, the tree appears to be about three inches tall. If I stand next to that tree, however, it appears to be over twenty feet tall. Now, Smiley, if I understand you correctly, you'd say that the tree is of some indeterminate height: even if we measured it precisely from the ground to the top, you'd still say that it was of "some" height, maybe twenty feet and maybe three inches, but no one could tell because "it's all relative." Right?
Not right. Once we measure the tree to be twenty feet high, the correct metaphor would be "Maybe twenty feet is considered short, or maybe it's considered tall". It could be both at the same time.
In reality, everything in the universe is short. Everything is the universe is also tall.

Any shade of gray can be considered black. Any shade can be considered white.

As long as the light is achromatic, then isn't black/white simply the intensity of such light? And wouldn't the number of lumens needed vary depending on the environment it's in?

Light is achromatic? Then how does a prism refract light into a spectrum?
Yes. All shades of gray (including black and white) are achromatic. They lack hue.

Let's stick with your original definition for now.

Smiley wrote:

Because it is, in the end, far preferable to your definition.

Your example merely served to demonstrate the inconsistency of your position.

You have stated that "black" and "white" are relative terms, in much the same way that "richer" and "poorer" or "taller" and "shorter" are relative terms. On the other hand, you've also stated: "White light is the color we see when all colors are present. Black light is the color we see when all colors are absent." In effect, then, "black" and "white" are absolute terms, in that they have, at least, a theoretical existence.

In other words, according to you, Smiley, "black" and "white" are both relative and absolute terms. This, I contend, they cannot be.

For example, you stated elsewhere that a certain shade of grey might be 50% black, which would make sense if "black" were an absolute measure (in the same way that it would make sense to say that A is 50% taller than B, as long as we could unambiguously ascertain the height of B). But you've said that "black" can never be ascertained, since it is an unattainable absolute, i.e. something that resembles the infinite. Yet 50% of infinity, as I mentioned before, is identical to "infinity." Thus, we can no more have a concept of "grey" than we could of "black." Either both are unascertainable, or both are ascertainable.

To say, then, that "black" and "white" are relative terms, but then to define other things on the basis of their "blackness" or "whiteness," is to make these relative terms self-referential. Let me offer an example: if I were to say "this tree is taller," one would presumably ask: "taller than what?" It would be unsatisfactory, however, to answer: "taller than taller," since "taller" can only be measured against some standard, not against itself. In other words, relative terms must reference something other than themselves.

Now, Smiley, with "black" and "white" as both relative and absolute terms, we are faced with the same problem. If I were to say "this object is black," then, insofar as "black" is a relative term, one would presumably inquire: "black in relation to what?" But since "black" is also absolute, I could respond: "black as black." And according to you, Smiley, that would be a satisfactory response, since "black" is both relative and absolute. In effect, then, black is the measure of blackness, which is a meaningless tautology.

Furthermore, this conundrum is not solved by simply saying that "black" and "white," although absolute, are only theoretically possible -- in other words, although we can talk as if there are such things as "black" and "white," they are, by definition, unattainable in their purest forms. For then we are still left with shades of grey that are intermediate stages between "black" and "white." If we cannot pin down the end points of the line between "black" and "white," we cannot do the same with any of the intermediate points either. Thus, not only are "black" and "white" indeterminate, but "grey" is as well.

Now, Smiley, I realize that you may be perfectly happy with this solution. After all, you've stated: "Any shade of gray can be considered black. Any shade can be considered white." In much the same sense, you also noted:

Smiley wrote:

In reality, everything in the universe is short. Everything is the universe is also tall.

There is some truth to this. After all, a grasshopper is a giant compared to a midge. And we can certainly say that a shade of grey may be "blacker" than another shade. But it is a far different thing to say that "any shade of grey can be considered black," for if "black" and "white" are relative terms, then they relate to each other inversely. In other words, if some shade of grey is "blacker" than another, then we must assume that the latter shade is "whiter" than the former.

In contrast, Smiley, you seem to suggest that "black" and "white" are not only relative terms, but they don't even relate to each other. For if they did, they could not be identical, just as the grasshopper and the midge, although both "short," are not as short as each other. In short, "black" and "white," even as purely relative terms, must relate to something: it seems that you want them to relate to "blackness" and "whiteness," which is an empty tautology.

And that, in sum, is why your definition is unsatisfactory.

Yes, and many other concepts. The opening post did not specify color.

Twyvel, two points. You are right to show the situational nature of color, and to give credit to the "internal" neurological contribution to the experience/sensation of color. But would you go so far as to argue that there is no contribution from the nature of the surface of snow and optical wave processes? In other words, will you recognize here the role of INTERACTIONISM--that it is the conjunction of "external" and "internal" forces that produce the experience of color? To me this is not dualistic objectivism, because "I" (the internal) and the snow (the external), together with physical optical phenomena, ARE ONE.
I think this "both-and" (rather than "either-or") perspective may come as close--intellectually--as one can get to the Buddha's Middle Way.

You can't contradict me with knowledge of what other colours are without conceding that knowledge of colours is possible, hence knowledge of black or white.

David Henry,

In answer to your question about " physical reality" and "human consciousness" I am saying they are co-existent. Neither has structure without the other. And "knowledge" is that aspect of consciousness which involves confidence in predicting outcomes of interactions with "the world". Since "time" is a psychological construct, then the extensions of "time": i.e. "prediction" ,"enduring structures" and "knowledge" are subjective and relative to the observer .

Twyvel, yes I was referring to the interaction between a neurological system and optical properties of the physical system's enviornment. So, I am talking about a body, not a self. But be aware that by interactionism I am not referring to some mundane casual bumping together or distinct objects (optical properties and a body); I am talking about an ABSOLUTE INTERACTIONISM, one that indicates the UNITY of the external and internal properties. In this way, I feel I can talk about what is ultimately a unity in dualistic terms. The unity of the cosmos is expressed in multiplicity, at least from the human perspective. You and I are ultimately ONE, but we are talking to one another across a great distance that actually connects us and IS us.

Black light is the color we see when all colors are absent.



Can you see something that is absent?

I accept you can see the absence of something. i.e "My car is not where I left it, someone call the police"

So you might argue, I see the absence of all colours and I will represent that state by naming it black, but it's surely contratictory to then describe it as a colour?

As far as we are concerned in the here and now, sure.....but do you believe the earth existed before your consciousness was developed?

Time is a concept, but it is based on the predictable behaviour of matter.

Yes, JLNobody, I think I see your point. Isn't this a hypothetical though?

e.g. That you and I are interacting is a hypothetical. External and internal properties is a hypothetical etc. Physiological functioning's and their causal relations are dualists explanations of how knowledge is acquired etc. etc.

Nondually it is all a spontaneous non-physical uncaused happening. And more correctly, neither physical nor nonphysical, or caused or uncaused etc.

There is no conceding as there was no denial that knowledge of colors was possible.

"The Earth", "matter" or any other concept have no objective reality in themselves. To ask if "the Earth" existed before "consciousness" is to beg the question of time as a product of consciousness unless we evoke a ubiquitous deity with "eternal consciousness". The world appears to be like it is because we appear to be like we are. Change either and you change both. This is the interactionist principle discussed on many previous threads (traceable through "fresco").
