"Culture, because it flows immediately from the spiritual and social character of man, has constant need of a just liberty in order to develop; it needs also the legitimate possibility of exercising its autonomy according to its own principles. It therefore rightly demands respect and enjoys a certain inviolability within the limits of the common good, as long, of course, as it preserves the rights of the individual and the community, whether particular or universal."
