"A great many things which in times of lesser knowledge we imagined to be superstitious or useless, prove today on examination to have been of immense value to mankind"

Human understanding is constantly evolving, and beliefs or practices once dismissed as mere superstition or nonsense often reveal their deeper purpose as our knowledge grows. Lafcadio Hearn’s observation emphasizes that what people once labeled as irrational or obsolete may, under new scrutiny, reveal layers of wisdom missed by earlier, less-informed generations. For centuries, rituals, traditions, and stories have shaped societies. Some were ridiculed by future ages, dismissed as relics of ignorance, yet, as sciences like anthropology, psychology, and medicine progress, a surprising number of these customs are vindicated.

Consider the example of herbal remedies once scorned as quackery but later found to contain potent natural compounds. Ancient dietary taboos, originally interpreted as baseless restrictions, have sometimes been shown to prevent disease or promote social cohesion. Likewise, communal rituals or myths served psychological or societal functions; they forged identity, fostered cooperation, or provided comfort against uncertainties. Early medical procedures, magic charms, or preventive measures, though mysterious in their explanation, sometimes embodied effective practices rooted in careful observation, their rationale simply lay beyond the contemporary understanding.

This reevaluation urges a reconsideration of inherited wisdom. What was once seen as ‘useless’ might have served as a vessel for practical knowledge, encoded in metaphor or symbolism to survive in oral traditions. Even practices driven by fear or legend could contain kernels of truth, as ancient warnings about tainted water or poisonous plants are now recognized as early public health measures. Furthermore, undervaluing such traditions risks severing ties with history, eliminating tools that guided humanity through centuries of uncertainty.

By acknowledging that past societies often operated with insight, however veiled, there emerges a kind of humility: a readiness to learn, to examine the wisdom within apparent folly, and to embrace the possibility that our current understanding, too, may one day be considered incomplete. The progression of knowledge, then, is not only about discarding the old, but re-examining it for the enduring value hidden beneath the surface.
