The Concept of Enlightenment

I was a bit uncomfortable with this essay especially when it came to talking about falsifiability.  For example, how can this guy prove to be true the love between a man and his wife unless he makes marriage something completely material? Also, I wonder why I agreed with the fact that he says to know something is to have power over it. It reminded me of when a friend of mine said to me to name something is already to begin to control such as with illness. I'm not really sure how easy it is to make verificationism a method by which we classify anything as true, since people today believe there are multiple truths.
