Okay kiddo, let me explain subvaluationism to you.
Have you ever played with toy cars and organized them by color? Maybe you put all the red ones in one pile, and all the blue ones in another. That's a kind of grouping or categorization, right?
Well, in subvaluationism, people try to do something similar with words or concepts. They group them according to how important or valuable they are. Some things might be really valuable or important, like diamonds or gold. Other things might be less valuable or important, like pencils or rocks.
But the thing is, sometimes it's hard to tell how valuable or important something really is. For example, some people might think that a certain kind of rock is very rare and valuable, while others might see it as just a bunch of ordinary pebbles.
And when it comes to words or concepts, there can be a lot of disagreement about how valuable or important they are. Some people might think that certain beliefs or ideas are really valuable and should be held onto tightly, while others might see them as just silly or unimportant.
So, subvaluationism is a way of trying to sort all these different values and judgments into different categories or groups. It can be really complicated, and people might disagree about how to do it or what belongs where. But ultimately, it's all about trying to make sense of the different ways that people value things and ideas.
