bq. “What Kinds of Things Are Natural”:http://brian.weatherson.org/wkotan.pdf

This is a short note arguing that the Lewisian picture works much more smoothly if you take the things that are more or less natural to be _functions_ from objects to magnitudes rather than _properties_. It’s indebted heavily to soon to be published work of John Hawthorne’s. Daniel Nolan tells me that Jack Smart has a similar view somewhere, but I haven’t been able to chase down the reference for that yet. So this probably isn’t an original view, but then again I’m much happier defending views of Smart’s than original views of my own!
