Usually without why, I don't think that something is worth knowing. "The unexamined life is not worth living" [Socrates] is also one of my mottoes. But not about some things, life, love, why things fall apart, etc. simply aren't reducible to knowledge and experience. Surprisingly, I couldn't get this song out of my head all this week. This song "I Can't Tell You Why" was originally by the Eagles. "Every time I try to walk away, something makes me turn around and stay. I can't tell you why" https://www.youtube.com/watch?v=uzNJT1jKeL0
