What makes a good concept?

A good concept is thought provoking matter created by the mind of a wicked genius. From the outside a good concept is mysterious and visually stimulating and from the inside it will reveal hidden truths. When enough time is spent with the good concept the spectator will gain a deeper insight of the world, based on the perception of the artist who created the work. Although, a good concept is not biased. A good concept appreciates that art is highly subjective and each spectator will leave with his or her own understanding of the work. This is not something that the artist can steal, just as a person cannot tell another person exactly how or what to think.
