Heraclitus sporophyte

Just dug out my Portugal photos, saw this one from Mateus Palace. Moss, nature's velvet. I looked for a quote from my favorite philosopher, Heraclitus, to pair with this, but couldn't find the one I wanted. Something about nature being always in a state of becoming. The quote may have passed out of existence, or more happily, transformed into something else, a sporophyte, maybe. Even Heraclitus must change.
 

Terry Pratchett

When I was a teacher at the natural science museum, one of the guys who ran Dinosaur Hall gave me Wyrd Sisters. "You would like this," he said. I thought it was glib. Then I noticed the terrific humor.  And the gift for drawing characters. And the wisdom--I wasn't expecting wisdom from a book with such a goofy, shiny cover. But you can't judge a book by its cover, as they say. Similarly, Terry Pratchett looked like a kindly, likeable, and quite handsome older fellow. But if we could see each other's souls, you would have seen a tidal wave of wisdom.  

In Hat Full of Sky, it's Miss Level I think who tells Tiffany, "There's no way things should be. There's just what happens, and what we do."

There's nothing more to say, beyond those two sentences. About anything.
