The principal aim of society is to protect individuals in the enjoyment of those absolute rights, which were vested in them by the immutable laws of nature, but which could not be preserved in peace without that mutual assistance and intercourse which is gained by the institution of friendly and social communities. Hence it follows, that the first and primary end of human laws is to maintain and regulate these absolute rights of individuals.
William Blackstone, Commentaries on the Laws of England (1765), vol. 1 1:120--41
