Values can’t be part of the objective world. Where does the word objective come from? Object. Our senses and our reason seem to be respresentations of objects and their physical properties. Values don’t represent/reflect anything in the world, instead, they’re merely responses to the world.
Let’s list some major properties of an apple. An apple is round, red, sweet, juicy, small and hard. Now of course, all these properties are in a sense relative. Round, in comparison to what? If things in general were a lot rounder, an apple wouldn’t seem so round. Hard, in comparison to what? In comparison to steel, an apple doesn’t seems so hard, in comparison to a sponge, it does. An apple wouldn’t seem so sweet if food in gernal was a lot sweeter. Is an apple good or bad? Humans tend to find apples good, Lions, not so much. Although, if somebody threw an apple at your head, that wouldn’t be very good, would it? All these properties we assign to apples like goodness, are dependant on the context it’s placed in. Taken out of it’s context, an apple is nothing, or at most, a potential something. So all of it’s properties are only coneivable within a certain context, including it’s supposed goodness.
Let’s deal with subjectivism. Back to the apples properties. Which one of these representations (I say representation, because we cannot percieve the apple without the medium of our senses and our reason. Reason organizes sense data to show relations between thing, which is essentially what an idea is) can actually be a part of the apple? Can roundness be part of the apple? I think so. An apple’s roudness seems to affect the way it interacts with other objects. You can’t roll a square object on the ground the way you can a round one. Can redness be part of an apple? Until recently, some scientists and philosophers didn’t think so, but according to modern optics, red is the way light reflects off of an object. Different colors mean different wave patterns, I think. Is sweetness a representation of a physical property inherent in an apple? Sure it is. Sweetness is a representation of the chemical sugar. Hardness is clearly a physical property, the harder something is, the more durable and resistant it is. See, all these properties appear to be representing something in the objective physical world. All of these properties affect the way the apple interacts with our bodies and other objects in a mechanistic, automatic way.
However, there is one property that is a little different than the others. Sweetness. The other properties seem more value free, don’t they? The other properties could work to your advantage depending on the circumstance, but sweetness seems inherently valuable for it’s own sake, doesn’t it? As I said before, sweetness represents sugar, sugar is a mechanistic, physical property of the world, capable of affecting other physical bodies. But what about the pleasant aspect of sugar? Can an objects pleasantness affect anything other than subjects? Do apples mechanistically gravitate towards other pleasant apples? A things pleasantness doesn’t seem to change the way it relates to objects. Only subjects are capable of finding things pleasant and desiring them. Sugar isn’t pleasant in and of itself. Pleasantness is something that subjects feel about objects. All these facts seem to indicate that a things pleasantness isn’t a part of the physical, objective world, but the mental, subjective world.
Yes, an objects properties are in some sense relative, in another sense absolute. A fat woman may be hard to lift for a weak man and easy to lift for a strong man, but harder to lift for them both, that’s absolute. If a woman is beautiful for one man, is she more beautful for all men? No. So beauty must be more relative and subjective than other properties.
Take two men and one woman for example. One man finds the woman beautiful, the other finds her ugly. If beauty and ugliness are objective properties of the physical world, how could she be both two things at once. It’s illogical to say that the woman is both beautiful and ugly at the same place and time, just as it would be illogical to say the woman is both heavier and lighter at the same place and time. Therefore, it must be the men who are reacting to the same properties in different ways. It has nothing to do with her body. Beauty is not a part of her body the way other things are like the way her weight and height. Beauty and Ugliness are in the minds of the beholder. Her body is the cause of two different effects. Their minds are designed to respond to her body differently. And because we’re all different, are brains are hardwired to value the same things differently.
There you have it. Aesthetics are relative and subjective. So are all values.
That being said, we’re all human, we’re all more or less the same. I’m sure the vast majority of us will be able to find some common values. If a lion were capable of articulating his values, I’m sure they’d be very different than our own.
