Book excerpt: Collecting the most incisive and influential writings of one of Rome's finest orators, Cicero's Selected Works is translated with an introduction by Michael Grant in Penguin Classics. Lawyer, philosopher, statesman and defender of Rome's Republic, Cicero was a master of eloquence, and his pure literary and oratorical style and strict sense of morality have been a powerful influence on European literature and thought for over two thousand years in matters of politics, philosophy, and faith. This selection demonstrates the diversity of his writings, and includes letters to friends and statesmen on Roman life and politics; the vitriolic Second Philippic Against Antony; and his two most famous philosophical treatises, On Duties and On Old Age - a celebration of his own declining years. Written at a time of brutal political and social change, Cicero's lucid ethical writings formed the foundation of the Western liberal tradition in political and moral thought that continues to this day.
