The discipline of folklore was founded during an era that was grappling with many of the same issues we are facing today. Obviously the lore itself has roots much older. But, prior to the Romantic Era, scholars and "civilized society" simply weren't paying attention.
The Romantic Era started in Europe as a pushback against Industrialization. The prior Scientific Revolution had shifted Western thought toward a more "rational" worldview; one that rejected the "superstition" found among the countryfolk. There were clear benefits and advancements in the birth of science and medicine, but one downside was the dismissal of age-old tradition and belief.
There is an important side to fairy tales which is often overlooked. Although I work within the European paradigm, what I will explore here is relevant to ALL cultures, as fairy tales exist universally among all people worldwide.
True fairy tales, not stories written solely by one author, but rather stories that were developed collectively over generations among language groups and cultures, have encoded in them important keys to understanding our own psyches.
