Google N-gram: Love, Joy, Peace, Hope
In the process of searching the internet for a book, I came across Google's N-gram. Google has scanned millions books (about six million books). The N-gram site lets you search for the frequency of words used. I searched for love, joy, peace and hope. Unfortunately, all of these words are on the downturn. Love has rebounded from a low in the 1970's. Peace had an interesting trend line with peaks near the end of the First and Second World Wars. There is still not a lot of joy out there.
