Kant's Groundwork of the Metaphysics of Morals › Why Kant Matters Now

Kant's ethics speaks directly to several contemporary concerns. _On human dignity and rights._ Kant provides one of the most powerful philosophical foundations for treating all persons with respect. The idea that humanity must never be treated merely as a means has become foundational for human rights discourse. When we object to slavery, torture, exploitation, and manipulation, we often invoke implicitly Kantian ideas about the inviolable dignity of persons. Whatever one thinks of his broader system, this insight remains morally serious. _In medical ethics._ The principle of informed consent, a cornerstone of modern medical practice, is deeply Kantian. To experiment on someone without their knowledge, or to deceive patients about their treatment, violates their autonomy and treats them merely as means. The emphasis on patient autonomy in contemporary bioethics owes much to Kant. _In business and technology._ The categorical imperative raises uncomfortable questions about common practices. Consider targeted advertising that exploits psychological vulnerabilities. Is this respecting consumers as ends, or treating them as means to profit? Consider gig economy arrangements that deny workers protections while extracting their labor. Is this consistent with recognizing their humanity? Consider AI systems that manipulate users toward engagement. Are we respecting persons or exploiting them? The question "What if everyone did this?" remains a powerful moral heuristic. Many dubious practices (tax evasion, free-riding on collective efforts, exploiting legal loopholes) fail the universalization test. They work only because most people do not do them. If everyone did, the system would collapse. This does not prove they are wrong, but it should give pause. _In personal life._ Kant challenges the way we think about relationships and commitments. A relationship based purely on what you can get from the other person treats them merely as a means. A friendship maintained only for networking is not genuine friendship. The moral life requires actually seeing others as ends, as beings with their own projects, purposes, and dignity, rather than as instruments for our goals. Kant also offers resources for thinking about self-respect and personal integrity. To fail to develop your talents, to deceive yourself, to sell out your principles for advantage: these violate duties to your own humanity. Even to yourself, you are more than a resource to be exploited. The Kantian perspective insists on honoring the dignity of your own rational nature. _In politics and public discourse._ The idea of universal law remains relevant. A policy that you would reject if it applied to you, or that depends on your group receiving special treatment, fails a basic test of moral legitimacy. The demand that moral principles be universalizable is also a demand for consistency: that we not carve out exceptions for ourselves or those we favor.
