It is easy to assert that people have, or ought to have rights, especially when we think ours are being violated. It is much harder to agree on what rights all people (regardless of place, status, or demographic trait) should have and which, therefore, we and our governments should respect and protect.
The following list of rights are drawn in close paraphrase from almost all of the clauses of the Universal Declaration of Human Rights. This declaration was adopted in 1948 by the UN General Assembly with no dissenting votes (albeit with abstentions by the Soviet bloc countries, Saudi Arabia, and South Africa). The rights that the UN membership with near unanimity recognized illustrate two of the important controversies about rights. One is the matter of cultural relativism. The Universal Declaration of Human Rights (UNDHR) in its preamble implicitly rejects the positivist concept that rights are culture-based by recognizing the existence of "inalienable rights of all members of the human family." The second controversy is whether rights involve only prohibitions on governments, and perhaps people, against specific abuses (such as abridging free speech), or whether rights extend to quality of life criteria (such as health and economic condition). You will note that beginning with number 20, the rights enumerated by the Universal Declaration include several quality of life standards.
One thing that you can do with this list, in your class or with your friends, is to constitute yourselves as the World Constitutional Convention, debate the various clauses of the UNDHR, and decide whether to ratify or reject each one of them. You might also decide to open them up for amendment. Finally, take note of clause 27 and ponder whether it provides too much of an escape clause that potentially allows governments to violate rights and to assert that doing so is necessitated by "the just requirements of morality, public order, and the general welfare in a democratic society."
