Oscar Wilde said this quote

“ Art, even the art of fullest scope and widest vision, can never really show us the external world. All that it shows us is our own soul, the one world of which we have any real cognisance. And the soul itself, the soul of each one of us, is to each one of us a mystery. It hides in the dark and broods, and consciousness cannot tell us of its workings. Consciousness, indeed, is quite inadequate to explain the contents of personality. It is Art, and Art only, that reveals us to ourselves. ”
