Socrates is an enigmatic figure, known chiefly through the accounts of others like Plato and Aristophanes. He was one of the most brilliant intellects ever, and devised what would later be called the Socratic method, which is a way of leading one's interlocutor to see his errors and contradictions through clever questioning before leading him to the truth. In ancient Athens, Socrates was widely known as a "gadfly", that is, an annoying insect buzzing at people's ears, because he kept questioning prejudices and contradictions; he was eventually tried and executed for "corrupting the minds of the youth".

Gautama Buddha is also known as Siddharta Gautama, or simply the Buddha, which means "Awakened" or "Enlightened". Born a prince, he chose a path of ascetism only to realize that it was as profound an illusion as self-indulgence. He achieved Enlightenment after 49 days of meditation; his awakening led him to discover the cause of suffering and the ways to eliminate it. These discoveries founded Buddhism, and his "Four Noble Truths" still form the heart of its teachings.

Albert Einstein is widely considered as one of the greatest minds that ever lived. He developed the theory of relativity, one of the two pillars of modern physics alongside quantum mechanics, and penned the world's most famous equation, E=mc².

Marcus Aurelius was a Roman Emperor, the last of the Five Good Emperors, and one of the most important Stoic philosophers, along with the slave Epictetus. Marcus Aurelius wrote the Meditations while in a military campaign; it was a series of notes written for no one but himself in his quest for self-improvement.

One of the undisputed giants in the history of human thought, and the founder of one of the world's longest-lasting cultural traditions, Confucius (known as Kong Fuzi in his native China) is arguably the most enduring of all the world's great thinkers. The Analects, the slender volume thought to have been compiled by his followers, has the strongest claim to represent Confucius' actual words. The book contains memorable sayings about the moral health of the individual, the family and the body politic.

Epictetus was born a slave, and became one of the most influent Stoic philosophers. Stoicism is the attitude allowing one to free oneself from the unnecessary suffering that arises from anxiety about events that are beyond our control; therefore, it can be of tremendous importance in one's life. According to Epictetus, our own actions and attitudes are the only thing in our control; whatever else happens, we should examine calmly and dispassionately, because no amount of suffering will change the impact of external events.

Nietzsche is a major figure in Western philosophy. His work is radical, sometimes violent, often ironic; it fascinates anyone bold enough to delve into it, exerted a profound influence on modern intellectual history, and covers a wide range of subjects. Nietzsche's writings border on the poetic; his aphorisms are particularly well-known for conveying all the radicality of his thinking in a intense but light, sometimes amusing manner.

Levitt and co-author Stephen J. Dubner show that economics is, at root, the study of incentives: how people get what they want, or need, especially when other people want or need the same thing. In Freakonomics, they explore the hidden side of...well, everything. The inner working of a crack gang...the truth about real-estate agents...the secrets of the Klu Klux Klan. What unites all these stories is a belief that the modern world is even more intriguing than we think. All it takes is a new way of looking, and Freakonomics will redefine the way we view the modern world.

Lao Tsu, also known as Lao Tzu or Laozi, is an ancient Chinese philosopher and sage, and an absolutely central figure in Asiatic culture. He is known as the author of the "Tao Te Ching" or "Daodejing" and the founder of Taoism. In traditional China, Taoism is a way of living in harmony with the Tao, "way", "path", or "principle", something that is both the source of, and the force behind, everything that exists. Throughout history, Laozi's work has been embraced by various anti-authoritarian movements, because his style is designed to elicit critical thinking through ambiguousness.
