ABSTRACT
It seems obvious that there are vague ways of
speaking and vague ways of thinking – saying that
the weather is hot, for example. Common sense also
has it that there is vagueness in the external world
(although this is not the usual view in philosophy).
Intuitively, clouds, for example, do not have sharp
spatiotemporal boundaries. But the thesis that
vagueness is real has spawned a number of deeply
perplexing paradoxes and problems. There is no
general agreement among philosophers about how
to understand vagueness.
