Intrinsic vs. Extrinsic Values
Values shape our decisions, beliefs, and how we judge what matters. One of the most fundamental questions in value theory is: does something have value on its own, or only because of what it leads to?
Intrinsic values have worth in and of themselves, independent of any external factors or consequences. Happiness is a classic example. You don't need to justify why happiness is good; it just is. Other examples include love, beauty, and knowledge.
Extrinsic values derive their worth from something else. Money is the go-to example here. A dollar bill isn't valuable because of the paper it's printed on. It's valuable because of what you can exchange it for. Other extrinsic values include:
- Status — valued for the social advantages it provides
- Power — valued for the ability to influence outcomes
- Fame — valued for the recognition and opportunities it brings
The key test: ask "Is this valuable because of what it leads to, or valuable for its own sake?" If it's only valuable as a means to something else, it's extrinsic.
Value Monism and Pluralism
Once you accept that some things are intrinsically valuable, the next question is: how many intrinsic values are there?
Value Monism
Value monism says there's exactly one ultimate intrinsic value, and all other values trace back to it. This simplifies ethical decision-making because you have a single standard to measure everything against.
The clearest example is utilitarianism, which treats well-being (or happiness) as the sole intrinsic value. On this view, money, freedom, and knowledge are all valuable only insofar as they promote well-being.

Value Pluralism
Value pluralism says there are multiple intrinsic values that can't be reduced to a single one. Individual autonomy, justice, beauty, and well-being might all be genuinely valuable in their own right.
This view better captures the complexity of real moral situations, but it creates a challenge: what do you do when intrinsic values conflict? For instance, a policy decision might pit individual rights against the common good, and there's no single master value to settle the dispute. Pluralism requires weighing and balancing values based on context rather than applying a formula.
Moral particularism is a form of value pluralism that takes this further, arguing that the moral significance of any factor (like honesty or harm) can change depending on the situation.
Incommensurability
Incommensurability is the idea that some values simply can't be ranked on a common scale. They're too fundamentally different to compare directly.
Consider: should a city preserve a historic building or tear it down to build a hospital that serves thousands of patients? The cultural value of the building and the health value of the hospital aren't measured in the same units. There's no formula that converts heritage into lives saved.
This matters because incommensurability means some moral dilemmas don't have a clean, calculable answer. Navigating them requires judgment and practical wisdom rather than a simple ranking.
Another example: weighing individual privacy against public safety in data collection policies. Both values are real, but they resist direct comparison.

Moral Pluralism vs. Moral Relativism
These two positions sound similar but are fundamentally different. Confusing them is a common mistake.
Moral pluralism holds that multiple objective moral values exist and are universally applicable. The values are real and binding on everyone, even though they sometimes conflict and require careful judgment to balance. For example, a judge might need to balance justice (fairness) and mercy (compassion) when sentencing. Both are real moral demands.
Moral relativism holds that moral values are relative to individuals or cultures. There are no universally binding moral norms. What's "right" depends entirely on who you ask or where you are.
Three key distinctions:
- Objectivity — Pluralism affirms that moral values are objective. Relativism denies it.
- Universality — Pluralism says some values apply to everyone. Relativism ties values to specific individuals or cultures.
- Disagreement — Pluralism treats moral disagreements as genuine disputes where someone can be wrong. Relativism treats them as mere differences in perspective.
A serious concern with relativism: it can struggle to condemn practices that violate widely shared moral intuitions. Cultural relativism, for instance, might justify oppressive practices simply because they're traditional within a given culture.
Metaethics and Moral Realism
The sections above deal with which values exist and how they relate. Metaethics steps back further and asks: what are moral claims, and can they be true or false at all?
Moral realism answers yes. Moral facts and properties exist independently of what anyone believes. The statement "torture is wrong" is objectively true or false, not just an expression of preference. Moral anti-realism denies this, holding that there are no objective moral facts.
A few related concepts worth knowing:
- Axiology is the broader philosophical study of value, covering both ethics (moral value) and aesthetics (artistic/beauty value). Value theory sits within axiology.
- Moral absolutism holds that certain moral principles apply in all situations without exception. Lying is always wrong, full stop.
- Moral universalism is slightly different: it says some moral principles are universally valid but may allow for contextual application. The principle holds everywhere, but how it applies can vary.
- Ethical egoism is the view that moral agents ought to act in their own self-interest. This is a normative claim (about what you should do), not just the observation that people tend to be self-interested.
