- If you don't think thats enough, could you perhaps explain one, two or all
- of the three things:
-
- 1) what will be enough ?
- 2) why people who have whatever you imagine to "enough" will
- agree with you ?
- 3) if you don't think that "enough" can be described,
- whether or not you agree that general optimism
- about the future is all that supports the morality
- of a lifestyle predicated on expansion ?
-
- Here are my answers to Barton-Davis's good questions.
-
- 1. There is no definition of enough. There will be limitations at
- some point in the future imposed by nature, and maybe the return on
- further effort will make leisure the most desirable good. We are
- very far from the limitations imposed by nature at present.
-
- 2. covered by the answer to (1).
-
- 3. A lot of scientific and technological information supports the
- view that expansion can be continued for several hundred years
- without jeopardizing anything essential for the welfare of humanity.
-
- 4. As humanity gets richer, it is motivated and able to devote
- increasing resources to the preservation of other forms of life.
- Very likely the present situation, in which the preservation of
- genetic resources, requires the maintenance of habitats is
- temporary.
-
- 5. Morality is a human invention, and human morality at present
- doesn't go very far in granting rights to viruses, bacteria,
- beetles and whales. The fact that some humans don't want whales
- killed has some force, just for that reason. By expressing their
- preference as a matter of rights, they have succeeded in avoiding
- the question of what they should pay to get others to honor their
- preference.
-
- The Nature Conservancy has my respect, because they express their
- preference for conserving nature by *buying* the land containing the
- nature they want to preserve.
