I'm currently behind on reviews, so don't be surprised if the recent reviews are a bit sparse.

it occurred to me that language always has the choice of development two ways. Consider: you’re inventing language and you come on an object for the first time, so you name it “tree.” Then you go on and you find another object. You have the choice of calling it a tree-only-with-special-properties, such as squat, hard, gray, leafless, and branchless, for instance – or you can name it a completely different object, say: “rock.” And then the next object you encounter you may decide is a “big rock,” or a “boulder,” or a “bush,” or “a small, squat tree,” and so on. Now two languages will not only have different words for the same things, but they will end up having divided those same things up into categories and properties along completely different lines. And that division, as much or more than the different words themselves, will naturally mold all the thinking of the people who use that language.
