Jul 31, 2012 at 6:03 comment added Trevor Wilson @Philip: a measure on a $\sigma$-algebra is usually required to be countably additive, not just finitely additive.
Jul 31, 2012 at 5:55 comment added Philip Brooker Maybe I'm missing something, but couldn't you just take a free ultrafilter on $X$ and let the measure of $S\subseteq X$ equal $1$ is $S$ belongs to the ultrafilter, and $0$ otherwise?
