Oh, I'd certainly say so. I've always thought a society is successful if the people who make it up consider it so, consider their lives satisfactory and sit high on any given hierarchy of needs. The Hierophany's citizens consider it successful, in large part, and are happy with the way of things. There are richer societies, more healthy, less violent or more egalitarian societies, but it passes my judgments even excepting my adherence to the Faith.

A society is often considered successful until it fails, in which case the model is considered a failure. Because of this, it would take an infinite amount of time to qualify as successful, hence, no societies truly being successful. Of course, I will not impose that definition on your sense of a successful society.
