In this chapter, I introduce the concept of the art-system, defined by the producer and the stories they tell, the seers, and the object that the producer makes, and the seers see. I introduce four types of definition: ostensive, lexical, operational and functional, and I also extend the categorization of different types of art used by John Robb and call them Art (a generic term), Art 1 (mostly what some specialists think of as “Fine Art”), Art 2 (Archeological Art) and Art 3 (the earliest stuff that gets called art, out of which other archeological art emerged). In addition, I discuss criteria from Gombrich (art is lifelike, involves unquestioned beliefs, is beautiful, uses skill and acute observation, and creates pleasure) and a dictionary definition (creativity, skill, imagination, beauty, and emotional power). All these criteria are related to the concept of aesthetics. I show how that has been resolved into a choice between “I like it” and “it is beautiful” and opt for the personal “I like it” because it requires all people involved in “art,” whether they are producers or seers to be agents in their own emotional reactions.
