Good post.
Someone: Capitalism is wrong.
Someone else:Capitalism is not wrong.
Will that example work?
Now again you have to describe how you use logic to arrive to the content of these statement. No how language works as such, but what the actual meaning has to do with logic. Both statements make sense in the English language and they are not meaningless nor illogical for how words work in general. I.e. syntax and semantics seems okay.
That requires us to define capitalism, define wrong, and then use logic to determine whether A (capitalism) does or does not equal B (wrong). How each person does that will depend on their particular political beliefs and so on. So I would have to evaluate each person's argument(s) to see if they are coherent or not.
So back to what I claimed: Between capitalism is wrong and capitalism is not wrong there is no way to use logic on those 2 as to decide between them. How? Because the actual meaning is not about logic, it is a subjective evaluation of 2 possible value systems.
It's not subjective once terms are defined. Capitalism has an objective, empirical definition. We can look out in the world and observe economies and determine if one is capitalistic or not. And it's not up to your individual opinion or mine. Either the economy meets the terms of the definition or it doesn't.
Same with wrongness. Once we get specific and develop real criteria for what determines the wrongness of something, we can look out in the world and objectively, empirically determine if a thing meets the criteria or not. And again, either my argument for labeling something "wrong" according to the definition I set is logically coherent, or it isn't.
So here it is for the world. Let us start with gravity and note that it is necessary to include gravity to describe the world, but not sufficient. I.e. gravity is not the world, it is a part of the world but not all of the world. So let us include logic as necessary. Now is logic as a process sufficient? Is all you have to do as a human to use logic?
See, that is how I ask the question. Not if logic is necessary, but if logic is sufficient?
And the answer is no! You can't describe the world and act in the world in pure logical terms and thus there can't be a logically coherent view of the world, because you can't do the world in only logical terms.
The fact that we need the empirical data of our senses, in addition to logic, to accurately understand the world, does not demonstrate that worldviews can't be logically coherent. That just doesn't follow. Once we have empirical data, we decide how to interpret it. Logic is the tool we use (or, should use) to do so. If we interpret that data in a way that logically coheres, then we've achieved a coherent worldview, by definition. I have yet to see how that is
impossible, which was what you claimed initially.
Surprisingly, you're now saying that logic is a
necessary (albeit insufficient) process for describing the world. How can you assert that, but not admit that views of the world can logically cohere? The debate seems over.
