This is a very important question. I think the best definition of human rights that I have ever read comes from the Declaration of Independence. It states that all men are created equal and endowed by their created with certain inalienable right. It also goes to say that all people have the right to life, liberty and happiness. Finally, it says that these rights are self-evident.
If you think about the words, it roots human rights in creation. Moreover, these words say that these rights are self-evident. In other words, you do not need proof. Just by virtue of being human, you have these rights. It does not matter who you are, what you do, or where you live. These words are powerful and a cornerstone to American society.
It will wise to remember these words and more importantly live them and share them with others.
