This is an interesting blog post partly because it confuses me.
I'm preparing to see if I can have laser eye surgery, and in order to do that I need to go off of the contacts I had been wearing. For a couple days everything was blurry, then when I put on contacts yesterday, everything was super clear.
Then I got to thinking, would we know what blurry is if we didn't know what clear was?
To make this bigger, can we say that there would be no good if there were no evil? How can we believe that there is good, if we believe that there is no evil?
I don't even know, so I'll have to do research.
