Question

why is egoism unique among ethical theories?
it is the only theory to acknowledge conflicting interests as harmful to a system of ethics.
it is the only theory to maintain that there are no universal truths regarding what is good.
it is the only theory to explain the way things ought to be in regards to what is right and wrong.
it is the only theory to equate what is good to what is performed in the name of self - interest.

Explanation:

1. Analyze each option:

• First option: Many ethical theories acknowledge conflicting interests, so this is incorrect.
• Second option: Relativist theories also claim no universal goods, so egoism isn't unique here.
• Third option: Most ethical theories explain right/wrong, so this is not unique to egoism.
• Fourth option (partially visible but inferable): Egoism uniquely equates what is good with actions done in self - interest. It focuses on self - interest as the basis for what is morally good, which is a defining feature of egoism among ethical theories.

Answer:

The option (the fourth one, partially visible but with the idea of equating what is good to what is performed in the name of self - interest) is the correct one. If we assume the fourth option is something like "It is the only theory to equate what is good to what is performed in the name of self - interest", then that is the correct option.
