If aesthetic judgments are purely subjective, calling any art objectively better than another becomes philosophically difficult to defend. Yet most people act as though some works are genuinely superior, not just differently liked.

If value is tied only to usefulness, this raises uncomfortable implications for how we treat people who can no longer contribute to society. Resolving this question remains foundational to debates on dignity and human rights.

Some argue nature has value independent of human interest, while others see environmental protection as justified only by its benefit to humans, directly or indirectly. This unresolved debate underlies much of environmental ethics.

Governments regularly allocate more resources and protection to their own citizens, but the philosophical justification for this unequal treatment of moral worth remains contested. This unresolved question underlies debates on immigration and international aid policy.

Some argue art should be evaluated purely on artistic merit, while others believe morally repugnant content diminishes a work's value regardless of technical skill. This unresolved debate continues to shape discussions of controversial art and literature.

Policy decisions often implicitly require comparing the value of different lives, such as in healthcare rationing, yet no philosophical framework has fully justified how such comparisons should be made. This unresolved question has real consequences in medical ethics.

Some philosophical traditions argue coming into existence carries a built-in risk of harm that non-existence avoids entirely, while most people intuitively value life as a good in itself. This unresolved debate underlies serious questions in population ethics.

Some philosophers argue all observation and reasoning is inevitably shaped by underlying values, while others maintain a meaningful distinction between fact and value can still be preserved. This unresolved question underlies much of epistemology and philosophy of science.

If someone's memories, personality, and values change completely, it's unclear whether they remain the same person in any meaningful moral or metaphysical sense. This unresolved question has real implications for how we treat people with advanced dementia.

Some ethical traditions treat honesty as an unconditional duty, while others argue truth should only be shared when it serves some positive purpose. This unresolved question complicates situations where truth offers little value beyond discomfort.

Judging historical figures by modern values can feel necessary for moral clarity, but it also risks ignoring the very different context they lived in. This unresolved tension continues to shape debates over monuments, legacies, and historical memory.

Some argue outcomes matter most regardless of how they were achieved, while others believe the means used fundamentally taint the value of the result. This unresolved tension appears throughout debates in both personal ethics and public policy.

Decisions made today, like saving money or maintaining health, assume some obligation to a future self who may have very different preferences and values. This unresolved question touches on both personal identity and long-term ethical responsibility.

Many reforestation projects plant fast-growing single species rather than rebuilding complex, biodiverse forest ecosystems, which limits their true ecological value. Making these projects genuinely restorative rather than just visually green remains an unresolved challenge.

As AI systems increasingly influence what billions of people see, believe, and decide, someone is effectively choosing the values baked into those systems. There's no agreed process for who that someone should be, or how they should be held accountable.

Free expression is valued almost everywhere, but so is protection from harassment, incitement, and harmful misinformation, and these values often conflict directly. No universal line exists for where one right ends and the other begins.

Because clean air and water aren't priced like other resources, they're often used or polluted without any real cost attached until the damage is severe. A better way to account for their true value could change how we protect them.

AI systems built in one country are used worldwide, but there's no shared international rulebook governing how they should behave. Without cooperation, regulation ends up fragmented and easy to bypass.

Current approaches to biotechnologies enabling the production of high-value materials from captured carbon dioxide either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

Achieving circular design rules and tracking systems for high-value consumer electronics at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.
