Vagueness demands many boundaries. Each is permissible, in that a thinker may without error use it to distinguish objects, though none is mandatory. This is revealed by a thought experiment—scrambled sorites—in which objects from a sorites series are presented in a random order, and subjects are required to make their judgments without access to any previous objects or their judgments concerning them.

This paper emerged from a class given jointly with Hans Kamp at NASSLLI 2012. Many thanks to Hans for help and comments at every stage. We plan a joint paper on the various ways in which context relates to vagueness. I would also like to thank the following for valuable comments: audiences at NASSLLI 2012, at the LOGOS conference Departing from Sainsbury, Barcleona 2012, and the Editor of this volume.
