The Red Book, published to wide acclaim in 2009, contains the nucleus of C. G. Jung's later works. It was here that he developed his principal theories of the archetypes, the collective unconscious, and the process of individuation that would transform psychotherapy from treatment of the sick into a means for the higher development of the personality.

When it first appeared in France, Anti-Oedipus was hailed as a masterpiece by some and "a work of heretical madness" by others. In it, Gilles Deleuze and Félix Guattari set forth the following theory: Western society's innate herd instinct has allowed the government, the media, and even the principles of economics to take advantage of each person's unwillingness to be cut off from the group. What's more, those who suffer from mental disorders may not be insane, but could be individuals in the purest sense, because they are by nature isolated from society.

In an attempt to appeal to the Medici family during the Italian Renaissance, Machiavelli outlines the way to acquire and retain political power, and how great men should behave in a princely government. The book is divided into four parts - types of principalities and state, proper conduct of a prince as military leader, personal conduct of a prince, and the disparity of Italy's political situation. Many listeners will be able to see principals that Machiavelli advocates for are still used in many political systems today.

Beyond Good and Evil confirmed Nietzsche's position as the towering European philosopher of his age. The work dramatically rejects the tradition of Western thought with its notions of truth and God, good and evil. Nietzsche demonstrates that the Christian world is steeped in a false piety and infected with a "slave morality". With wit and energy, he turns from this critique to a philosophy that celebrates the present and demands that the individual imposes their own "will to power" upon the world.

The Brothers Karamazov is a murder mystery, a courtroom drama, and an exploration of erotic rivalry in a series of triangular love affairs involving the “wicked and sentimental” Fyodor Pavlovich Karamazov and his three sons—the impulsive and sensual Dmitri; the coldly rational Ivan; and the healthy, red-cheeked young novice Alyosha. Through the gripping events of their story, Dostoevsky portrays the whole of Russian life, is social and spiritual striving, in what was both the golden age and a tragic turning point in Russian culture.
