The human mind is an amazing instrument capable of processing data from multiple inputs at speeds that make the fastest microprocessor look like a slow moving cement mixer. Not only that but many of the functions it performs are sorted and prioritized without the owner even seeing or sensing the processes involved. One of the astonishing abilities of the mind is the interpretation and creation of symbols: one thing standing for another thing. Letters form words that the brain then interprets. A picture of shape that is roundish, red, and has a sticklike appendage near the top becomes an apple. I catch sight of a piece of leaf with just the stem and a small part of the base and I see a tadpole swimming on my carpet.
Art, whether written, pictorial, or musical, is the mind's conscious manipulation of symbols to create images, emotion, and meaning in the mind of the observer/listener. I take something that is not there, create symbols (words or images), and deliver it to you so that you have an experience. Creating words from letters, then forming sentences, all of which describe the world, exterior and interior, is really an astounding activity and yet so many of us, from children to the most humble, can do it. Of course a lot of people tend to stick to the literal, the true, the tangible. It takes another flight of fancy to make stuff up - to make beautiful meaningful lies.
But even the entirely made up should be full of truths eternal. They may be very small, but I believe that even in the most lighthearted or humorous or fanciful piece of fiction writing there should be yet another layer of meaning underneath the obvious. I should be able to paint a picture for you of another reality and underlying my fictional reality is yet another substrate of meaning, of symbol. A really satisfying work of art lingers with you a long time after experiencing it. It's the movie that makes you keep thinking days later, or the novel that resonates years in the future so that you have to pick it up again, and lo and behold there is even more there than the first time around. It's the painting that haunts, or the musical refrain that moves you to tears and you don't know exactly why.
If I can ever write just one novel that has the ability to resonant in the reader's mind long after they put it down I'll have succeeded as an artist. If someone reads my words like I can read the remains of a leaf as a tadpole on my carpet then I have done my job.
