Perhaps the first comprehensive ethics program in American dental schools was created in 1990 at the University of Kentucky by then dean David Nash. Nash recounts the emergence of his personal and professional interest in ethics using the structure of Daniel Levinson's book The Seasons of a Man's Life. Each season brings tasks of evolving and deepening ethical engagement. Being ethical is important; helping others to be so is special. Nash still teaches the course.
