In 1957, four years before his death, Carl Gustav Jung, psychiatrist and psychologist, began writing his life story. But what started as an exercise in autobiography soon morphed into an altogether more profound undertaking. The result is an absorbing piece of self-analysis: a frank statement of faith, philosophy, and principles from one of the great explorers of the human mind.

Whenever we worry about what to eat, how to love, or simply how to be happy, we are worrying about how to lead a good life. No goal is more elusive. In How to Be a Stoic, philosopher Massimo Pigliucci offers Stoicism, the ancient philosophy that inspired the great emperor Marcus Aurelius, as the best way to attain it. Stoicism is a pragmatic philosophy that teaches us to act depending on what is within our control and separate things worth getting upset about from those that are not.

Robert Sapolsky’s Behave, his now classic account of why humans do good and why they do bad, pointed toward an unsettling conclusion: We may not grasp the precise marriage of nature and nurture that creates the physics and chemistry at the base of human behavior, but that doesn’t mean it doesn’t exist. Now, in Determined, Sapolsky takes his argument all the way, mounting a brilliant (and in his inimitable way, delightful) full-frontal assault on the pleasant fantasy that there is some separate self telling our biology what to do.

Published first in 1912, Psychology of the Unconscious was one of the most important stepping stones in the development of Jung’s thought and practice. It has a long subtitle: A Study of the Transformations and Symbolisms of the Libido. A Contribution to the History of the Evolution of Thought. This expressed the underlying impetus - a break from the view of the libido and its functions as taught by Sigmund Freud, which Jung had earlier adopted. It was from this point that the two approaches, which came to be known as the Swiss and Viennese schools, emerged.

Epictetus, a Greek stoic and freed slave, ran a thriving philosophy school in Nicropolis in the early second century AD. His animated discussions were celebrated for their rhetorical wizardry and were written down by Arrian, his most famous pupil. Together with the Enchiridion, a manual of his main ideas, and the fragments collected here, The Discourses argue that happiness lies in learning to perceive exactly what is in our power to change and what is not, and in embracing our fate to live in harmony with god and nature.
