This is part of the preamble. Whereas recognition of the inherent dignity and of the equal and inalienable rights of all members of the human family is the foundation of freedom, justice, and peace in the world. Whereas disregard and contempt for human rights have resulted in barbarous acts which have outraged the conscience of mankind, remember, World War II just happened, and the advent of a world in which human beings shall enjoy freedom of speech and belief and freedom from fear and want as has been proclaimed as the highest aspiration of the common people. Now, therefore, the General Assembly proclaims this Universal Declaration of Human Rights as a common standard of achievement for all peoples and all nations. You might be thinking, why do they even have to write this? Well, think about it. Things like the constitutions of various countries, especially the United States, these only applied to those countries.
