If your a historian or collector then you want fluxus to be dead as soon as possible.
If you are a fluxus artist you want it to live for ever.
There it is in a nutshell.
The whole idea of it comes from the Catholic church traditions of canonizing saints.
They have to be dead before you can glorify them.
But that does not mean that you should kill the saint in order to rever them.
But if you have built a church to that saint that you hope to profit from and it cannot be opened until after their death, then the saint beware!
