People I regularly talk to don’t even believe truth exists as a fundamental concept anymore.

That’s quite tragic. All the more so since, even though they may not want to admit it, in practice nobody can go through everyday life without believing in some form of objective truth.

When you go to cross the street, either there is a car coming or there isn’t. You’re not questioning the concept of truth when you see incoming traffic and (hopefully) choose not to walk into it.

So all that this talk of not believing in the concept of truth or objective reality is, is a way to rationalize their cognitive dissonance and their hypocrisy to make themselves feel better.

They know they’re believing lies but the lies make them feel good so they come up with this cope.
