What is truth anyway?
We all know it when we see it. At least we think we do. But what we often call truth is merely consensus. We should always be wary of confusing the two.
For instance, you can’t have an argument with someone who fundamentally believes that the sky is red. The reason they believe this is because the color that everyone else calls blue, they call red. No matter how much you argue with them, or show them examples, or find other people to back the fact that the sky is blue and not red, as long as they believe blue is red you can’t have a rational conversation about the color of the sky.
But here, you are not arguing about the truth (though you both likely believe you are). You are arguing about consensus. What is at stake? Who does it harm, really, if that lone outsider calls the sky red, or orange, or purple?
The truth is really that thing that you can’t deny. That thing for which, all names aside, there can be no disagreement. Let’s all work better at coming to agreement and consensus (or agree to disagree) around that which is, in fact, perception so that we can have more truthful discussion.
