But that’s not really how truth works. Truth is essentially an act of trust, an act of faith in some authority that is telling you something that you could not possibly come to realize yourself. What’s a quark? You believe that there are quarks in the universe, probably because you’ve been told by people who probably know what they’re talking about that there are quarks. You believe the physicists. But you’ve never seen a quark. I’ve never seen a quark. We accept this as truth because we’ve accepted the authority of the people who told us it’s true.
