Aristotle's Nicomachean Ethics, said to be dedicated to Aristotle's son, Nicomachus, is widely regarded as one of the most important works in the history of Western philosophy. Addressing the question of how men should best live, Aristotle's treatise is not a mere philosophical meditation on the subject, but a practical examination that aims to provide a guide for living out its recommendations.

One of the most significant books ever written by a head of state, the Meditations are a collection of philosophical thoughts by the Emperor Marcus Aurelius (121-180 ce). Covering issues such as duty, forgiveness, brotherhood, strength in adversity and the best way to approach life and death, the Meditations have inspired thinkers, poets and politicians since their first publication more than 500 years ago. Today, the book stands as one of the great guides and companions—a cornerstone of Western thought.

Phaedrus lures Socrates outside the walls of Athens, where he seldom goes, by promising to share a new work by his friend and mentor, Lysias, a famous writer of speeches. This dialogue provides a powerful example of the dialectical writing that Plato uses to manifest ideas that are essential to human existence and to living a good life. Phaedrus shows how oral and written forms of language relate to each other and to philosophy.

The dramatic nature of Plato's dialogues is delightfully evident in Symposium. The marriage between character and thought bursts forth as the guests gather at Agathon's house to celebrate the success of his first tragedy. With wit and insight, they all present their ideas about love - from Erixymachus' scientific naturalism to Aristophanes' comic fantasy. The unexpected arrival of Alcibiades breaks the spell cast by Diotima's ethereal climb up the staircase of love to beauty itself.

After more than 2,300 years, the Greek philosopher Aristotle still remains one of the most influential thinkers who has ever lived. There was hardly any field of human knowledge in existence during his day in which he did not make a major contribution. Additionally, he probed areas which were never before examined. Indeed, one could make the claim that no individual person has ever known as much about this world as Aristotle. His analyses of zoology and logic paved the way for modern forensic techniques, and for which every scientist down to this day owes him a debt of gratitude.

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.

Roman statesman and philosopher Marcus Tullius Cicero wrote on a wide range of subjects, from Greek philosophy to moral duty to friendship. Though he considered philosophy secondary to politics and often used his writings for explicit political ends, his work has nevertheless been widely read for over two thousand years and has influenced everything from the culture of the Renaissance to the ideals of the founding fathers of the United States.

A classic work of military strategy, On War sets forth the theories and tactics of Carl von Clausewitz, a distinguished Prussian general who was notable for his roles in the French Revolutionary and Napoleonic Wars. The book covers a broad range of topics, including weapons, terrain, troops, and leadership, as well as the importance of defense over offence, the balance of power, and the subordination of war to politics. Praised for its timeless insights, Clausewitz’s treatise is often compared to the work of Machiavelli and Sun Tzu, and remains relevant to military leaders.

In The Republic, Socrates is asked the question: "What is justice?" And in order to answer it, he draws a long and detailed analogy between the individual and the city. Plato’s work forms the foundation of Western philosophy and covers a wide range of topics including political theory and ethics, with extended digressions into artistic and literary criticism, the theory and practice of education as well as epistemology and metaphysics.
