Deontology: Some Things Are Simply Wrong

You’re offered a deal: sacrifice one stranger to save a packed stadium. Almost everyone says, “I’d do it.” Yet many of those same people insist torture is always wrong—even to stop an attack. How can we believe both? That tension sits at the heart of today’s episode.

Kant thought our moral life shouldn’t feel like balancing a messy spreadsheet of pleasures and pains. Instead, he argued, some actions are off-limits—full stop—because they fail a deeper test: could you will a world where everyone acted this way, and still respect every person as an end in themselves? Deontologists say morality is more like following the internal “operating system” of rational beings than crunching external outcomes. That’s why Kant’s 1785 Groundwork aims to locate morality in the very structure of reason, not in shifting social opinions. Later, W.D. Ross complicated this picture by claiming we’re bound by several basic duties at once: keeping promises, doing no harm, showing gratitude, and more. These duties can clash, but they’re not just suggestions; they function like moral “default settings” we’re responsible for honoring—even when it’s inconvenient or costly.

Modern law quietly sides with this stricter vision of morality more often than we notice. When Germany’s Constitutional Court rejected shooting down hijacked planes in 2006, it wasn’t maximizing outcomes; it was drawing a hard line around each person’s inviolability. Medical ethics codes and the GDPR do something similar: they don’t just ask, “Will this help overall?” but “Are we honoring this person’s status and choices?” Deontology, in practice, shows up whenever rules protect someone precisely when breaking them looks temptingly useful.
