Frequently we encounter this rejection in the form of criticism, criticism of our efforts, our work, even ourselves.
Rejection and failure are facts of our existence. When an artist's work is rejected or negatively critiqued, he or she is often told "don't take it personally, they are not rejecting you, just your work." This is a reflection of post-enlightenment thinking that considers art an end unto itself. It considers art in a vacuum, unrelated to the context in which it was created or the purpose it serves because to our modern way of thinking, those considerations are irrelevant.
