Does light have color

I think the opponent completely misses the mark here. I will briefly rebut, then give two reasons that should show I have won this debate. The RebuttalThe opponent argues that color is a qualia -- a philosophical term which basically refers to something that is a subjective, personal experience. While the opponent may claim that he does not need a definition of color, his entire "qualia argument" necessariy assumes that color is defined as being a qualia. The opposition fails, however, to demonstrate why his definition is preferable to my own.I'll briefly mention that the opponent states roughly that, "the definition of color is not relevant, we're not debating color, we're debating whether color is a property of light". This statement is logically self defeating, as we cannot talk about whether "color is a property of light" without knowing what "light", "property" and "color" mean. We are clearly using common sense terms for "light" and "property", leaving us with the burden of defining color. I have done this, as has the opponent (even if in implication only.)----------------------The two following points will demonstrate why I have won today's round. 1. The opponent cannot fulfill his burden of proof. In this debate, the opponent accepted the burden of proof in the first round. In this particular round, he claimed that he would "prove that light itself has no color". If he is unable to do this, he cannot win the round. Refer to his previous argument in which he states that, "There are numerous definitions [for light] and no two are the same. Everyone just picks the one that most agrees with their understanding of how light works..." In this statement, the opponent agrees that color can have many different, conflicting definitions. In ceding this fact, the opponent is effectively admitting that he cannot prove his qualia definition of light is anymore correct than my physics-based definition of light. And while I cannot prove my definition is any more correct than his on an objective level (see argument two), that is not my job, as I did not accept the burden of proof upon my own shoulders like the opponent did. Since the opponent cannot (and has not) demonstrated his definition to be objectively true, he has failed to uphold his burden of proof. Because he has failed in this, he cannot win this debate. And since he cannot win, I am the natural alternative. 2. Even if we were debating a slightly different topic, I would still win.Let us suppose that we are not debating whether color is an objective quality of light, but instead we were debating which of our two definitions was a better definition. In this case, I would still win this debate. Allow me to explain. As qualia is a definitionally subjective experience, defining color as a qualia necessarily makes color a subjective idea. In fact, without a mind to comprehend it, color wouldn't exist at all. (A claim the opponent has made.)From a scientific standard, this definition is a mistake. Philosophically speaking, categories are extremely important, as they allow us to differentiate different objects. Categories are often best determined by looking at two objects that differ in a single way. For instance, if you had two 1 cm in diameter wooden balls next to each other, you would find it difficult to determine any category. But if one wooden ball was 1cm wide while the other was 2cm wide, you'd easily be able to define the category of "size".In another instance, on might be a wooden ball while the other might be a wooden cube. In this case, the obvious category would be "shape". In determining whether a category should be made, you imagine the "nearly identical" object test and see if the proposed category creates any useful distinction between the two objects. The opponent would have you believe that if a human mind wasn't present, there would be virtually no different between two otherwise identical objects that have only a different color. In fact, he would laught at the notion that objects have real color at all. (When I say color, I am referring the color of the reflected light off that object.)However we know this is not the case. Even without a mind to see it, two otherwise identical objects possessing two different colors can have noticeable impacts on the world around it. Consider shirts, identical in every way except there color. One is black, one is white. If you were to wear the black shirt, you'd find yourself getting much hotter than if you had worn the white shirt. This shows that the color of the two objects creates an objective difference between the two such that a category can safely be determined. Of course, the explanation behind the differences in shirt temperatures comes from physics, which is non-coincidentally where my definition of color comes from. Both philosophically and scientifically speaking, basing color upon physics helps to create an objective category that cannot otherwise exist if color was thought of only as a qualia. We live in a world such that the better we can explain it in objective terms, the better off we are. In defining color as merely a qualia, we are left unable to accurately or adequately describe the color of something. For this reason, my definition of color is preferable to my opponent's. ConclusionI have demonstrated that the opponent has failed in upholding the burden of proof he set for himself in the first round. On this alone, he has lost the debate. Beyond that, I endeavored to show that my definition of color was preferable to his, as it creates an objective standard for color, something more useful and preferable in terms of both science and philosophy. I look forward to the final round and I thank the voters for reading this far.
