In The Politics Aristotle addresses the questions that lie at the heart of political science. How should society be ordered to ensure the happiness of the individual? Which forms of government are best and how should they be maintained? By analysing a range of city constitutions - oligarchies, democracies and tyrannies - he seeks to establish the strengths and weaknesses of each system, and to decide which are the most effective, in theory and in practice. Like his predecessor Plato, Aristotle believed that the ideal constitution should be good in itself and in accordance with nature, and that it is needed by man - 'a political animal' - to fulfil his potential. A hugely significant work, which has influenced thinkers as diverse as Thomas Aquinas and Machiavelli, The Politics remains an outstanding commentary on fundamental political issues.
