*there’s no such thing as “a woman”, or “a man”
Well, no. Those are not things.
"a woman" is a signifier for the thing we call a woman, which is the signified. The two together make the sign. They are connected arbitrarily by agreed meaning. It only means something if we share the agreed meaning.

This is about the best thing I've read this week, if not this month! Brilliant and witty.
