Ideally an artwork needs no explanation; the work resting on its own merits. Nonetheless, an account may reveal what the artist wanted to do, what social forces were at work, whether the artist wanted to change society's perception of the world or if it was simply some hack work made on commission. When the public is confronted with unconventional new work using a Distilled Light mode, the artist should 'stand in the dock'. Knowing the artist's intentions lifts the veil of unfamiliarity so that a critic can assess the relevance of a work for themselves.
Artists are scolded for failing to mimic patterns of nature when our real task is to make nature echo the aberrations in ourselves. There are rhythms in the heart and soul not always present in landscapes of this world.
