Over two millennia after its compilation, the Politics still offers much to consider with regards to political science. Aristotle's succinct and thoughtful analysis is based on his study of over 150 city constitutions and covers the gamut of political issues in order to establish which types of constitution are best, ideally as well as for particular circumstances, and how they may be maintained.

In Aristotle's Rhetoric, the philosopher identifies rhetoric as one of the three key elements of philosophy, along with logic and dialectic. According to Aristotle, logic is concerned with reasoning to reach scientific certainty while dialectic and rhetoric - because they are concerned with probability - are the branches of philosophy best suited to human affairs. Rhetoric is a tool for practical debate, a means for persuading a general audience to resolve practical issues using probable knowledge.  

In 1656, after being excommunicated from Amsterdam's Portuguese-Jewish community for "abominable heresies" and "monstrous deeds", the young Baruch Spinoza abandoned his family's import business to dedicate his life to philosophy. He quickly became notorious across Europe for his views on God, the Bible, and miracles, as well as for his uncompromising defense of free thought. Yet the radicalism of Spinoza's views has long obscured that his primary reason for turning to philosophy was to answer one of humanity's most urgent questions....

Gorgias of Leontini, a famous teacher of rhetoric, has come to Athens to recruit students, promising to teach them how to become leaders in politics and business. A group has gathered at Callicles' house to hear Gorgias demonstrate the power of his art. This dialogue blends comic and serious discussion of the best life, providing a penetrating examination of ethics.

How remarkable that an Italian living in the 15th and 16th centuries should lend his name to a word still in common usage in the English language today. Nicolo Machiavelli (1469-1527) wrote only one major work as a gift for his ruling Prince, Lorenzo de Medici. Machiavelli held office as a senior civil servant for 14 years until the downfall of the Republic in 1512. No longer officially employed to impart advice, instead Machiavelli poured out his ideas and resentment in his writings.

In the first century BC, Marcus Tullius Cicero, orator, statesman and defender of republican values, created these philosophical treatises on such diverse topics as friendship, religion, death, fate and scientific inquiry. A pragmatist at heart, Cicero's philosophies were frequently personal and ethical, drawn not from abstract reasoning but through careful observation of the world. The resulting works remind us of the importance of social ties, the questions of free will and the justification of any creative endeavour.   

The Republic, Plato's masterwork, was first enjoyed 2,400 years ago and remains one of the most widely read books in the world. Presented as a dialogue between Plato's teacher Socrates and various interlocutors, it is an exhortation to philosophy, inviting its listeners to reflect on the choices to be made if we are to live the best life available to us. This complex, dynamic work creates a picture of an ideal society governed not by the desire for money, power or fame, but by philosophy, wisdom and justice.

Thomas More's "Utopia" is a complex, innovative and insightful contribution to the development of political thought. The culmination of this work was a description of a country whose society lives according to the laws of nature, but is close to the ideas of the religion of Christianity - they have everything in common and gold is not valuable to them. Based on the ideas of Plato, St. Augustine and Aristotle, the Utopia novel has borne fruit, namely the dawn of new utopian and anti-utopian literature that includes the writings of such writers as Francis Bacon, Herbert Wells, Aldous Huxley and George Ourell.

The Theory of Moral Sentiments (1759) was the first major text by Adam Smith who, seven years later, was to publish what was to become one of the major economic classics, The Wealth of Nations (1776). However, Smith regarded The Theory of Moral Sentiments as his most important work because in it he identified the profound human instinct to act not necessarily in self-interest but through, as he phrased it, a ‘mutual sympathy of sentiments’. 

The object of this book is to provide a simple introduction to the Indian systems of philosophy. Each one of these systems has had a vast and varied development. Attempt has been made to introduce the listener to the spirit and outlook of Indian philosophy and help him to grasp thoroughly the central ideas rather than acquaint him with minute details. Modern students of philosophy feel many difficulties in understanding the Indian problems and theories. 

David Hume (1711-1776) was the most important philosopher ever to write in English as well as a master stylist. This volume contains his major philosophical works. A Treatise of Human Nature (1739–1740), published while Hume was still in his twenties, consists of three books on the understanding, the passions, and morals.

"The Art of Controversy or The Art of Being Right" is an acidulous, sarcastic treatise written by the German philosopher Arthur Schopenhauer. In it, Schopenhauer examines a total of thirty-eight methods of showing up one's opponent in a debate. He introduces his essay with the idea that philosophers have concentrated in ample measure on the rules of logic, but have not engaged with the darker art of the dialectic, of controversy.

Enquiry Concerning Political Justice and Its Influence on Morals and Happiness by William Godwin (1756-1836) was first published in February 1793, the month following the execution of Louis XVI of France. It proved to be immediately popular and influential. Godwin, the son of a Calvinist preacher, was educated at Hoxton Academy, after which, he became a minister to a dissenter congregation in Ware. 

Marcus Tullius Cicero (106 B.C.-43 B.C.) is one of the seminal figures in the history of Western philosophy, politics, and letters. On Moral Ends (De Finibus) is considered by many to be his most important work in philosophy. In a series of stimulating dialogues, Cicero seeks to answer the question "What is humanity's Ultimate Good?" by examining the ethical systems of three different schools of thought. In so doing, he reveals powerful and startling truths about wisdom, virtue, and our deepest desires. Quintus Curtius is the pen name of attorney and translator George J. Thomas.
