Paul Taylor, "The Ethics of Respect for Nature" (1981)
Environmental decisions involving plants (and people and animals) (book, p. 256)



_______________________


Respect for nature

An individual plant/animal has "a good of its own." Read p. 199 A&B

This doesn't require sentience or interests.  Read p. 199-200 C

He's talking about wild plants/animals, and not taking a stand on others.  Read p. 200 D
A thing with a good of its own has inherent worth, and therefore we owe it respect.  Read p. 201 E

Points later in reading: we and plants and animals are fellow members of one biotic community




Respecting a giant sequoia

Obligations to WILD plants and animals

We have prima facie obligations to wild plants and animals. Read p. 198 F
What does he mean by a "prima facie moral obligation"? At first glance. Not absolute. Could be overridden by other obligations. 

  1. Prima facie obligation to tree
  2. Prima facie obligation to a human being 
Bad ways to resolve conflicts

  1. Humans are superior, so we win (Taylor: humans not superior)
  2. Only humans have rights, so we win (Taylor: yes only humans have rights, which give us inviolability; but no that doesn't mean we always win)

Priority principles for resolving conflicts (Taylor, "Competing Claims" p. 263). 

A. The principle of self-defense
B. The principle of proportionality
C. The principle of minimum wrong
D. The principle of distributive justice
E. The principle of restitutive justice

 



Priority principle A: self-defense

Persons: pursuing life or other crucial goods
Plants/animals: pursuing life or other crucial goods by threatening humans
Principle: You can defend yourself in the least harmful way available

Applications
Which of these are allowed under the Self-defense Principle?
  1. Shooting an attacking bear
  2. Killing a bear that's on your property
  3. Cutting down a wild tree that threatens to fall on someone
  4. Using weed killer on wild poison ivy
  5. Killing wild fish if I'm starving in the woods



Priority principle D: distributive justice

Persons: pursuing life or other crucial goods
Plants/animals: pursuing life or other crucial goods but not threatening humans
Principle: I should distribute seriously good things and bad things fairly.

Applications
  1. Must kill fish to stay alive--may I?  Taylor says: It's not unfair to choose my own life.
  2. Suppose I could kill a plant instead of a fish, would that be better?


Priority principle B: proportionality

Persons: pursuing something trivial
Plants/animals: pursuing life or other crucial goods and not threatening humans
Principle: I should give up trivial goods that are seriously costly for plants and animals.


Applications (all bad, says Taylor)
  1. Cutting down wild redwoods to create beautiful furniture
  2. Picking wildflowers for a bouquet
  3. Killing wild animals for fun or trophies


Priority principle C: minimum wrong

Persons: pursuing something important, but not absolutely essential
Plants/animals: pursuing life or other crucial goods and not threatening humans
Principle: I can pursue such goals if I minimize the wrongs done to plants and animals as much as possible

Applications
  1. Cutting down a forest to build an art museum? Ok if we build tall, to save trees
  2. Cutting down trees to build apartments, an airport, etc.




Priority principle E: restitution

Persons: have harmed plants/animals despite following the other principles
Plants/animals: some are dead or have been harmed
Principle: I should make up for the harm by doing something good for plants/animals

Applications

  1. After killing animal for food, perform acts of kindness.
  2. After destroying forest for art museum, plant more trees.
