You can imagine the culture shock someone would have if they disappeared from Earth for a few decades only to return and see what we’ve done to the place.
This week, at a premiere of the movie The Space Between Us (all about a boy raised on Mars who comes back to Earth for a girl), Neil deGrasse Tyson was asked by Vulture what he would say to someone like that.
His answer was all about the different types of truths we have floating around right now.
The first, he said, is “an objective truth that can be established outside of your own mental state,” such as by the methods and tools of science. This is the kind of truth that is true “whether or not you believe in [it],” he said, “so I would recommend that if you base policy on any kind of truth, it should be that truth.”
The third category was reserved for someone like Donald Trump.
The third kind of truth, he said, is what he calls “political truth.” “That’s what’s true simply because you repeat it so often that everyone thinks that it’s true, even if it’s not the truth,” Tyson said.
Sadly, we’re living in a country where this kind of alternative truth — a.k.a. A lie — is spreading faster than we can contain it. We have to be vigilant and vocal if we want our society governed by objective truths.
