Being a dyed-in-tweed conservative, I generally feel ill-disposed towards conceptual art but I really loved the Antony Gormley exhibition at the RA, whenever that was.
I was going to slag conceptual art off but now I've remembered the Gormley exhibition it's disarmed me.
Perhaps I could argue that Gormley's sculptures are fascinating in of themselves, fascinating enough to sustain his concepts, though I'm not sure that's true.
I also enjoyed the fact that you could make up meanings for these objects (prompted, of course, by the explanatory notes), they would provoke thought, not dictate it.
