final structure took form in the second draft prepared by French jurist René Cassin, who worked on the initial draft prepared by Canadian legal scholar John Peters Humphrey. The Declaration consists of the following: The preamble sets out the historical and social causes that led to the necessity of drafting the Declaration. Articles 1–2 establish the basic concepts of dignity, liberty, and equality. Articles 3–5 establish other individual rights, such as the right to life and the prohibition of slavery and torture. Articles 6–11 refer to the fundamental legality of human rights with specific remedies cited for their defence when violated. Articles 12–17 set forth the rights of the individual towards the community, including freedom of movement and residence within each state, the right of property and the right to a nationality. Articles 18–21 sanction the so-called "constitutional liberties" and spiritual, public, and political freedoms, such as freedom of thought, opinion, expression, religion and conscience, word, peaceful association of the individual, and receiving and imparting information and ideas through any media. Articles 22–27 sanction an individual's economic, social and cultural rights, including healthcare. It upholds an expansive right to an adequate standard of living, and makes special mention of care given to those in motherhood or childhood. Articles 28–30 establish the general means of exercising these rights, the areas in which the rights of the individual cannot be applied, the duty of the individual to society, and the prohibition of the use of rights in contravention of the purposes of the United Nations Organization. Cassin compared the Declaration to the portico of a Greek temple, with a foundation, steps, four columns, and a pediment. Articles 1 and 2—with their principles of dignity, liberty, equality and brotherhood—served as the foundation blocks. The seven paragraphs of the preamble, setting out the reasons for the Declaration, represent the steps leading up to the temple. The main body of the Declaration forms the four columns. The first column (articles 3–11) constitutes rights of the individual, such as the right to life and the prohibition of slavery. The second column (articles 12–17) constitutes the rights of the individual in civil and political society. The third column (articles 18–21) is concerned with spiritual, public, and political freedoms, such as freedom of religion and freedom of association. The fourth column (articles 22–27) sets out social, economic, and cultural rights. Finally, the last three articles provide the pediment
