This was the year I discovered Ludwig Wittgenstein. The primary principle I've been able to absorb so far is that if one can't live their philosophy then it's no good. He was a purist, typical of saints. I think saints in the Christian Church are the only ones who actually manage to live Christianity. Below is a very entertaining lecture on Wittgenstein that I got from YouTube. I'm sure you will enjoy it if you take the time to listen to it.
