In very other period of art history, the idea itself –the what – had been primary. Today the idea matters less than the way it is arrived at; it is the how that makes the work. This word brings us again face to face with the theme and its infinite variations. It is no longer a matter of knowing, of possessing the truth, but of approaching it... knowing that the road is long, knowing that the road does not end, knowing that the road is the end in itself.
