Intrinsic value is the value nature has in itself, independently of its usefulness to anyone. Extrinsic value is value derived from nature's relationship to something else, especially the benefits it provides to humans or other living beings.
The Core Distinction
In environmental philosophy, asking whether nature has intrinsic value affects its moral standing. If a forest has intrinsic value, there may be a moral reason to protect it even when doing so produces no economic or practical benefit.
Extrinsic value is often treated as instrumental value: something is valuable as a means to a further end. A forest, for example, may supply timber, absorb carbon dioxide, support tourism, or improve human well-being. Its value is then explained through what it provides.
| Type of value | Source of value | Environmental example |
|---|---|---|
| Intrinsic value | The entity is valuable in itself | A species deserves protection even if it has no known human use. |
| Extrinsic value | The entity is valuable because of its relationship to another end | A wetland is valuable because it reduces flooding and filters water. |
The distinction also separates anthropocentric and non-anthropocentric approaches. Anthropocentrism generally evaluates nature by reference to human interests, emphasizing extrinsic value. Non-anthropocentric positions, such as biocentrism or ecocentrism, may attribute intrinsic value to individual organisms, species, ecosystems, or the biosphere.
However, the two forms of value are not mutually exclusive. A river can have intrinsic value while also providing drinking water and supporting agriculture. The philosophical disagreement concerns whether its usefulness fully explains its value.
A common misconception is that extrinsic value means “financial value.” This is too narrow: aesthetic enjoyment, cultural identity, scientific knowledge, and ecosystem stability can also be extrinsic benefits.
IB Exam Technique
For Philosophy and the environment (HL), first define both concepts, then apply them to one clear environmental case. In an evaluative response, examine whether intrinsic value can be justified independently of human judgement, and avoid merely listing environmental benefits without addressing the underlying philosophical claim.
