Main thesis: The welfare of animals is entirely dependent on human interests.
(p. 134) Criteria or assumptions:
1. People should be free to do as they wish short of
interfering with the interests of other humans.
2. Conservation is necessary since resources can never
satisfy the needs of all humans.
3. Every human is deserving of respect and fairness in
the application of the community's rules.
4. Every human is entitled to a decent minimum of wealth
to avoid permanent privation.
Note: On p. 134, Baxter states a project of ethical theory.
If you disagree with his particular judgments on clean air, water, etc.,
he observes, you may have a more fundamental disagreement. You are likely,
for example, to disagree with Baxter's criteria when you disagree with
his particular judgments. If you disagree with his particular judgments,
Baxter points out, "the task will then be yours to identify the basic set
of criteria upon which your particular judgments rest." Baxter here describes
an important feature of ethical theory: an invitation to each person to
identify and examine the assumptions of his or her judgments.
