<P> According to Norberto Bobbio, one of the major exponents of this distinction, the Left believes in attempting to eradicate social inequality - believing it to be unethical or unnatural while the Right regards most social inequality as the result of ineradicable natural inequalities, and sees attempts to enforce social equality as utopian or authoritarian . Some ideologies, notably Christian Democracy, claim to combine left and right wing politics; according to Geoffrey K. Roberts and Patricia Hogwood, "In terms of ideology, Christian Democracy has incorporated many of the views held by liberals, conservatives and socialists within a wider framework of moral and Christian principles ." Movements which claim or formerly claimed to be above the left - right divide include Fascist Terza Posizione economic politics in Italy, Peronism in Argentina, and National Action Party in Mexico . </P> <P> Authoritarianism and libertarianism refer to the amount of individual freedom each person possesses in that society relative to the state . One author describes authoritarian political systems as those where "individual rights and goals are subjugated to group goals, expectations and conformities", while libertarians generally oppose the state and hold the individual as sovereign . In their purest form, libertarians are anarchists, who argue for the total abolition of the state, of political parties and of other political entities, while the purest authoritarians are, by definition, totalitarians who support state control over all aspects of society . </P> <P> For instance, classical liberalism (also known as laissez - faire liberalism,) is a doctrine stressing individual freedom and limited government . This includes the importance of human rationality, individual property rights, free markets, natural rights, the protection of civil liberties, constitutional limitation of government, and individual freedom from restraint as exemplified in the writings of John Locke, Adam Smith, David Hume, David Ricardo, Voltaire, Montesquieu and others . According to the libertarian Institute for Humane Studies, "the libertarian, or' classical liberal,' perspective is that individual well - being, prosperity, and social harmony are fostered by' as much liberty as possible' and' as little government as necessary ."' For anarchist political philosopher L. Susan Brown "Liberalism and anarchism are two political philosophies that are fundamentally concerned with individual freedom yet differ from one another in very distinct ways . Anarchism shares with liberalism a radical commitment to individual freedom while rejecting liberalism's competitive property relations ." </P>
