Ethicist: Many environmentalists hold that the natural environment is morally valuable for its own sake,regardless of any benefits it provides us.However,even if nature has no moral value,nature can be regarded as worth preserving simply on the grounds that people find it beautiful.Moreover,because it is philosophically disputable whether nature is morally valuable but undeniable that it is beautiful,an argument for preserving nature that emphasizes nature’s beauty will be less vulnerable to logical objections than one that emphasizes its moral value.
The ethicist’s reasoning most closely conforms to which one of the following principles?
Interesting passage. Roughly speaking, it says we can debate whether nature has X. But we can't deny it has Y. If therefore someone says, we should preserve nature because of Y, it's comparitively harder to logically object to.
(E) An argument for preserving nature will be less open to logical objections if it appeals to a characteristic that can be regarded as a basis
for preserving nature and that philosophically indisputably belongs to nature.
This is the answer. Because everyone agrees that nature has beauty, it's harder to object based on that value compared to when someone brings up a value which is debatable (its moral value).
