Ideal truths are different from absolute truths, in that ideal truths are truths we recognize as not being entirely true...yet. But we want to work towards making them true.
Progress will never come from assuming you are right and/or assuming someone else is wrong.
Progress comes from assuming you might be wrong, and figuring out how you can fix that.
Because the only actions we can truly control are our own. We cannot dictate those of everyone else. We cannot make them do anything, even if we think them doing something would be good. So what we can do, is personally make sure our actions are the best they can be, in pursuit of our ideal truth.
Because we all hold ideal truths. Most of us, more or less, hold the same ideal truths, even! If we actually were to focus on the part which mattered, the pursuit of that ideal truth as individuals, then we might actually make progress. But by trying to shift responsibility onto someone else, by trying to make it "not my problem", by trying to make it "your fault", we lose sight of that.
And everyone is guilty of that, to at least some extent. I know I am, especially the "not my problem" part. Anyone who claims they aren't guilty of it is, by the way, inherently proving they are, because by saying, "I swear there's no possible way I'm guilty!", you are by definition saying, "I swear that it's the fault of someone else!". Shifting responsibility. Shifting blame.
And it's true, that in me writing this. I am in fact guilty of the same exact sin. Because by saying, "everyone, including you, is guilty", I am placing fault on people outside of myself, shifting at least some blame onto them. I'm not going to make an excuse for that, though. I'm going to own up to it. I'm selfish enough to not be selfless enough to try and fix everything I could. The ideal truth of the world is something I would love to see, but I am actively guilty of not pursuing it the vast majority of my day.
But beyond that, I leave conclusions up to you, since I think it only fair to. If my philosophy holds any ground in reality, then just as it is my job to assess me, it is your place (not mine) to assess you. The only person who should be allowed to judge a person is that person themselves, and all that.
Personally, while I kinda like this philosophy, inherent in it I gotta admit is a bit of smugness bordering on hypocrisy, but I like to think it at least has a good goal in mind: try to be the best person you can be, because the best world we all want is one where more people act that way, more or less.
