"There seems to be a tacit agreement about what it is not polite to mention, what it is not appropriate to portray. For some of us, that polite behavior is set so deeply we truly do not see what seems outside that tacit agreement. We have lost the imagination for what our real lives have been or continue to be, what happens when we go home and close the door on the outside world. Since so many would like us to never mention anything unsettling anyway, the impulse to be quiet, the impulse to deny and pretend, becomes very strong. But the artist knows all about that impulse. The artist knows that it must be resisted. Art is not meant to be polite, secret, coded or timid. Art is the sphere in which that impulse to hide and lie is the most dangerous. In art, transgression is holy, revelation a sacrament, and pursing one's personal truth the only sure validation."
