Of Natural Rights, Pierre Elliott Trudeau said these are:
"rights to which all men were entitled because they are endowed with a moral and rational nature. The denial of such rights was regarded as an affront to 'natural" law' - those elementary principles of justice which apply to all human beings by virtue of their common possession of the capacity to reason.
"These natural rights were the origins of the western world's more modern concepts of individual freedom and equality.
"Cicero said of natural law that it was 'unchanging and everlasting', that it was 'one eternal and unchangeable law ... valid for all nations and for all times.'"
