We relate to our world through symbols and representations. Often, a single symbol can conjure up a whole world of meaning. Thoughts and feelings can lie hidden for years, and can be brought forward by the whiff of a familiar scent or the strains of a familiar melody. The representations are hard-wired into our brains and we couldn't function without them. They are what enable us to make sense of the world around us.
Art is full of symbols and representations in their purest form.
That is why art, including the fine arts and the performing arts, can be such a powerful spark for creativity. For centuries, the rich and powerful have sought art in their lives. Generally, when the rich and powerful want something, it is very much worth having. In the practical world of business and commerce, we sometimes make the mistake of dismissing art as frivolous. It is not.
