One of the enduring fixtures of an arts education is the "critique," a group evaluation of students' work. Traditionally some posturing, passive-aggression and even unkindness can be expected during a critique, even from a teacher, and the experience can be confusing and discouraging.
The 1980s generated the idea of the fine artist as rock star, coming on fast and furious at a young age, entering the international art circuit, cashing in quickly because no one lasts more than a decade. It can happen, it has happened, but it doesn't happen very often.
We can be truthful in our endeavors, search for objectivity, keep a critical eye, but if we forget we always are -- despite our best intentions -- in a subjective space, we are lying to ourselves and to others.
