The alchemy of good curating amounts to this: sometimes placing one work of art near another makes one and one equal three. Two artworks arranged alchemically leave each intact, transform both and create a third thing. This third, thing and the two original things then trigger cascades of thought and reaction; you know things you didn’t know you needed to know until you know them; then you can’t imagine ever not knowing them again. Then these things transform all the other things and thoughts you’ve had. This chain-reaction is thrilling and uncanny.
