To ask about the 'source' of rights or morals assumes an erreous conclusion. To ask about the source of morals is to assume that such a source exists. As if it existed outside of human constructed systems. The 'source' is the human ability to learn from experience and to entrench rights in our laws and in our consciousness. Our rights come from our long history of wrongs.
