Today we elaborate on what it takes to differentiate between a "true" proposition and a "false" proposition. The answer is philosophical pragmatism. A synthetic proposition (some claim about the external world) is only as "true" as its ability to inform my actions toward predictable outcomes. This is the guiding principle that universally appeals to all human interests.
If you agree (even in part), then GREAT! We can finally have a discussion with the potential to objectively settle disputes.
If you disagree entirely, then GREAT! Nobody cares what you think anymore. I could concede everything you believe and not a single decision in my entire life needs to change as a result. So fine. I believe whatever you say. But until you can give me some tangible reason to commit my actions toward some outcome, then I'm not going to do anything differently.
