My wife (of ten years today) used this line a few years ago. At first, I was baffled. I thought it was a misquote of the idiom “seeing is believing”. However, the more I pondered the quote, the more it made sense.
Sight is information. This information interpreted and we need to believe that this interpretation is a representation of something that’s real.
So, we do need to believe in order for us to see.
Happy 10th anniversary, my 🐈.
