One person's truth is another person's falsehood.
You can call something "truth" or "science" or "consensus" all day in an effort to make others believe your viewpoint is just that.
But there are in fact multiple versions of the truth. By the very nature that disagreements concerning important issues abound.
When someone tries to tell me their viewpoint is the "truth", I immediately begin to figure out how that all unravels when put up against competing versions of the "truth".
There used to be a saying in Soviet times about the 2 state run organs of information. "There's no Pravda in Tass, and there's no Tass in Pravda". Meaning there's no truth in the news, and no news in the truth.
The only real truth or science is skepticism. Understanding that every interaction is somehow an attempt at manipulation.
It's not always done by design. Our interaction here right now is an example. Once one understands this and has the introspection to question their own beliefs no matter how painful that may be. That's when one finds the "truth".
Otherwise, you're just regurgitating what you've been told to believe as "truth".
This is nonsensical. There is one truth. You’re discussing perspective and belief while awarding truth to everyone with perspective and belief. That is a very odd path.
