Expression is never considered a given, and it is in fact maybe not what's most interesting about making art. Making art, since 1960 or something, is many things: it's a way of doing philosophy, it's a way of opening a dialogue, it's a way of putting a fact or a question out into the world, or a way of drawing people into new relationships, or a way of interrogating history. It's all these other sorts of strategies or techniques or processes that are really interesting and really valuable.
