Some philosophers have argued that there exist certain human or natural rights
that belong to all human beings by virtue of their humanity. But a review of
the laws of different societies shows that the rights accorded a person vary
from society to society and even within a society over time. Since there is no
right that is universally
protected, there are no natural rights.

A defender of the theory that natural rights do exist might respond to this
objection by arguing that

A) some human beings do not have any natural rights
B) some human rights are natural, whereas others derive from a source such as a
constitution
C) people in one society may have natural rights that people in another society
lack
D) all societies have some institution that protects the rights of an
individual in that society
E) natural rights may exist even though they are not protected by some
societies
