Joseph Conrad on Art and Seeing

"And art itself may be defined as a single-minded attempt to render the highest kind of justice to the visible universe, by bringing to light the truth, manifold and one, underlying its every aspect. It is an attempt to find in its forms, in its colours, in its light, in its shadows, in the aspects of matter and in the facts of life, what of each is fundamental, what is enduring and essential -- their one illuminating and convincing quality -- the very truth of their existence.
...
My task which I am trying to achieve is, by the power of the written word to make you hear, to make you feel--it is, before all, to make you see. That--and no more, and it is everything. If I succeed, you shall find there according to your deserts: encouragement, consolation, fear, charm--all you demand--and, perhaps, also that glimpse of truth for which you have forgotten to ask."
-Joseph Conrad in Preface to The Nigger of the Narcissus

This short preface is perhaps my favorite piece on the nature, aim and purpose of art.
