Do you ever question the nature of your reality?

And I don't mean rejecting the viewpoints of your opponents, but I mean questioning everything that you can't personally confirm. Like, did the Peloponnesian War really happen? Could any historical event be an outright fabrication? Or loosely based on reality? Can the consensus behind many health topics be an outright lie to manipulate us or to sell products? Are published government statistics just made up to hide reality from us? Is the Overton window placed firmly in the realm of lies, and are we unable to speak the truth about many subjects, like about human nature?

Can you accept that anything you believe to be true, because you were told it's true, can just outright be wrong or a lie?
