If you’re like me and sometimes have trouble distinguishing synthetic propositions from analytic ones then maybe this submission from a philosophy student’s paper will help. I quote:
“All husbands have heads” is synthetic and “all wives are are married” is analytic. We never see a husband without a head. However it is possible for us to imagine a husband with no head. He may be being kept alive by a system of tubes and motors and was able to marry. This man would still be a man like any other, but headless.
See, now that clears everything up well doesn’t it?
