Full Idea
It is possible, I take it, that there might be simple natural properties different from any that instantiated within our world.

A Reaction
Interesting. Fine for Lewis, of course, for whom possibilities seem (to me) to be just logical possibilities. Even a scientific essentialist, though, must allow that different stuff might exist, which might have different intrinsic properties.
