Which of the following does Peter Singer assert about the principle of equality? (Points : 1)

People should have equal rights because they are factually equal.
People with higher abilities, it stands to reason, should have greater rights.
Different groups of humans should have equal rights if scientific investigation proves that there are no genetic differences in their abilities.
It is a prescription that we should treat people equally regardless of their differing abilities.

Singer has stated that many people judge him based on secondhand summaries and short quotations taken out of context, not his books or articles, The choices given here for the "right" answer are secondhand summaries taken out of context.

Given that objection, the second response <<People with higher abilities, it stands to reason, should have greater rights. >> Probably applies more to Singer's rights to Animals, however, Singer would cringe at this description of his work, and I wouldn't blame him.
I too have often been judged and ridiculed for folks misunderstanding second hand gossip and summaries (SHe said that I said...) Pox on your instructor for doing this.

To determine what Peter Singer asserts about the principle of equality, we can start by understanding his overall philosophy. Peter Singer is a prominent philosopher and ethical thinker known for his work on animal ethics and global poverty. He argues for a principle of equality that extends beyond traditional considerations such as race or gender.

In the given options, the correct assertion about the principle of equality according to Peter Singer is:

"It is a prescription that we should treat people equally regardless of their differing abilities."

Peter Singer argues that equality should be based on moral considerations rather than factual or genetic differences. He believes that individuals should be treated equally based on their inherent moral worth and capacity to suffer and experience pleasure, rather than their abilities or attributes.

To arrive at this conclusion, you can research or read Peter Singer's works, such as his book "Practical Ethics," where he explains his views on equality and the treatment of individuals with differing abilities.
