Art has no definition, yet it can be defined. Art is subjective and expressive, beautiful and debase, literal and figurative, and still yet elusive. Conception can be the plan or intention and yet be the act, and communication and expression are not all that different. Art is a word that is expansive, in that it incompasses many forms, and it evolves over time. You cannot define it, truly, because it also changes with time and fashion--what is hot today, may not be hot tomorrow-- and yet again, there is junk-art and fine-art. Come on, enjoy, and be done with it.
