Introduction: The Spectrum of Value

This unit looks at the core question of environmental ethics: Where do we draw the line of moral value?

• Intrinsic Value: Something that is valuable in itself, for its own sake (e.g., a person, happiness).
• Instrumental Value: Something that is valuable as a tool or resource to get something else (e.g., money, a hammer).

The traditional (Western) view was that only humans have intrinsic value, and nature only has instrumental value. These theories challenge that.

Anthropocentrism (Human-Centered)

Anthropocentrism (from Greek anthropos, "human") is the traditional view that humans are the center of the moral universe.

• Core Belief: Only human beings have intrinsic value.
• View of Nature: The natural world (animals, plants, rivers, etc.) has only instrumental value. Its value is determined by its usefulness to humans.
• Ethical Consequence: We should protect the environment, but only because it benefits us. For example, we should stop pollution *because* it harms human health, or save rainforests *because* they provide oxygen and potential medicines for humans.
• This is often called "Shallow Ecology" (by its critics).

Biocentrism (Life-Centered)

Biocentrism (from Greek bios, "life") is a theory that extends intrinsic value to all individual living things.

• Core Belief: All living beings (humans, animals, plants, fungi, bacteria) have intrinsic value simply because they are alive and have a "good of their own"—a drive to survive, grow, and flourish.
• Proponent: Paul Taylor ("Respect for Nature"). He argued that humans are not superior to other life forms, but are just one part of the community of life, with equal moral standing.
• Ethical Consequence: We have a duty to respect *all* life, not just human life. This makes actions like clear-cutting a forest or pointless swatting of insects morally problematic.
• This is an individualistic theory: It focuses on the value of *individual* organisms, not the ecosystem as a whole.

Ecocentrism (Ecosystem-Centered)

Ecocentrism (from Greek oikos, "home" or "ecosystem") is a theory that extends intrinsic value to the entire ecosystem as a whole.

• Core Belief: This is a holistic view. The "moral patient" is the entire biosphere. Intrinsic value is not in individual organisms but in the *system* itself—the species, the land, the rivers, the atmosphere, and the relationships between them.
• Proponent: Aldo Leopold ("The Land Ethic"). He proposed a new ethic that "enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land."
• Leopold's Maxim:

  "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise."

• Ethical Consequence: Our primary duty is to the health of the ecosystem. This can lead to different conclusions than biocentrism.
  • Example: An ecocentrist might support hunting an overpopulated deer species (to protect the stability of the forest), while a biocentrist (who values each individual deer) would be against it.
