The art we commonly call abstract is a message from the non-human. But it’s not so clear exactly what qualifies. A stone on the ground is of the inhuman universe, but conventional criticism claims that the fact that the stone has been bought and sold in a load of gravel means that there is no outside to the human world. An artist should say otherwise, that no matter to what uses the stone is put it remains untouched. It is not sentimental to assert that the human world has limits, and that human beings overvalue themselves and overestimate their power.
