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. 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.

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.

Voltaire was a French writer famous for his wit and irony. They were his tools for launching vitriolic attacks on the established Catholic church, the adversaries of freedom of religion and expression, and on separation of church and state. His prolific writing took almost every possible literary form: plays, novels, essays, but also poems, historical and scientific works.

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".

The philosophy of Confucius was so powerful that it dominated intellectual life in ancient China for centuries. It even came to be considered a religion, and there are still temples where Confucius is worshipped as the God of Culture.

"The Prince" is the most famous of Machiavelli's works; it gives very clear, precise and realistic instructions on how to gain and maintain power, fortune, and glory, sometimes at the expense of others. Written in 1513, it is one of the most feared and hated political treatises, taken to be the first work in which the effect the leader desires to achieve is taken as more important than any abstract ideal or ethical value that might prevent him from taking immoral action.

If you want to change the world, start off by making your bed. On May 17, 2014, Admiral William H. McRaven addressed the graduating class of the University of Texas at Austin on their Commencement day. Taking inspiration from the university's slogan, "What starts here changes the world," he shared the ten principles he learned during Navy Seal training that helped him overcome challenges not only in his training and long Naval career, but also throughout his life; and he explained how anyone can use these basic lessons to change themselves - and the world - for the better.

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.

Napoleon Bonaparte was one of the greatest military figures ever. He rose to prominence during the French Revolution, after which he kept on soaring higher and higher until he was crowned Emperor of the French. He then moved on to gain control of the whole of continental Europe, before the ultimate defeat of 1815. Today, his campaigns are studied in every military school, his liberal politics have had a strong legacy worldwide, and he remains one of the most celebrated and controversial political figures in Western history.

These 100 quotes have been carefully selected to introduce you to his character and his way of thinking, and to inspire you into making your own discoveries about the unconscious.

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.

The ancient Toltecs believed that life, as we perceive it, is a dream. We each live in our own personal dream, and these come together to form the dream of the planet, or the world in which we live. Problems arise when our perception of the dream becomes clouded with negativity, drama, and judgment (of ourselves and others), because it's in these moments of suffering that we have forgotten that we are the architects of our own reality and we have the power to change our dream if we choose.
