If wisdom is, as philosophers, theologians, and now even scientists agree, “morally grounded,” then it must rest on an objective, transcendent foundation. If moral truth is merely a matter of personal or popular opinion, then wisdom itself becomes negotiable, and even the most heinous acts could be called wise under the right circumstances. But this is not what we mean by wisdom.

Everyone, it seems, is on a quest for wisdom. Bookstore shelves overflow with self-help guides, and “wisdom literature” has been a mainstay of religious tradition for centuries. The allure of wisdom is universal, crossing the boundaries between the devout and the secular. We are drawn to any promise of insight, eager to possess this prized quality. Yet, for all our enthusiasm, we often blur the line between wisdom and knowledge. Dictionaries sometimes define wisdom as “accumulated learning” or “scholarly knowledge,” but if that were all wisdom entailed, why not simply call it “knowledge”? Clearly, wisdom hints at something deeper, something richer.

Some have turned to science to clarify the mystery. Igor Grossmann, a psychology professor and director of the Wisdom and Culture Lab at the University of Waterloo, assembled a team of behavioral and social scientists to see if a scientific consensus on wisdom’s nature could be reached. Their findings? “Moral aspiration” emerged as one of the two central pillars of wisdom. In other words, these scientists—echoing the conclusions of countless philosophers—regarded wisdom as inseparable from morality.

Consider this: Is it possible to murder wisely? Or is murder, by its very nature, always unwise because it is immoral? The answer points us to a crucial truth: wisdom is not just about cleverness or intellect; it is bound up with moral goodness. But this realization complicates matters. If wisdom is defined by moral virtue, who decides what counts as “good”? Science excels at describing what is, but it cannot dictate what ought to be. David Hume recognized this centuries ago, observing that no amount of empirical observation can bridge the gap between facts and values.

So, where do we turn for moral direction if science cannot provide it? Can individuals simply decide for themselves what is good or evil? In a culture where truth is increasingly seen as subjective—shaped by personal experience and opinion—it is tempting to imagine that each person is the ultimate authority on moral truth. But this idea quickly unravels.
