Maria Sibylla Merian, a German painter and naturalist, produced an innovative work on tropical insects based on lore she gathered from the Carib, Arawak, and African women of Suriname.

This book is the story of how three brilliant scholars and one ambitious freshman crossed paths in the early sixties at a Harvard-sponsored psychedelic-drug research project, transforming their lives and American culture and launching the mind/body/spirit movement that inspired the explosion of yoga classes, organic produce, and alternative medicine. The four men came together in a time of upheaval and experimentation, and their exploration of an expanded consciousness set the stage for the social, spiritual, sexual, and psychological revolution of the 1960s. Timothy Leary would be the rebellious trickster, the premier proponent of the therapeutic and spiritual benefits of LSD, advising a generation to "turn on, tune in, and drop out." Richard Alpert would be the seeker, traveling to India and returning to America as Ram Dass, reborn as a spiritual leader with his "Be Here Now" mantra, inspiring a restless army of spiritual pilgrims. Huston Smith would be the teacher, practicing every world religion, introducing the Dalai Lama to the West, and educating generations of Americans to adopt a more tolerant, inclusive attitude toward other cultures' beliefs. And young Andrew Weil would be the healer, becoming the undisputed leader of alternative medicine, devoting his life to the holistic reformation of the American health care system. It was meant to be a time of joy, of peace, and of love, but behind the scenes lurked backstabbing, jealousy, and outright betrayal. In spite of their personal conflicts, the members of the Harvard Psychedelic Club would forever change the way Americans view religion and practice medicine, and the very way we look at body and soul.

"The ancient Greeks argued that the best life was filled with beauty, truth, justice, play and love. The mathematician Francis Su knows just where to find them."--Kevin Hartnett, Quanta Magazine" This is perhaps the most important mathematics book of our time. Francis Su shows mathematics is an experience of the mind and, most important, of the heart."--James Tanton, Global Math Project For mathematician Francis Su, a society without mathematical affection is like a city without concerts, parks, or museums. To miss out on mathematics is to live without experiencing some of humanity's most beautiful ideas. In this profound book, written for a wide audience but especially for those disenchanted by their past experiences, an award-winning mathematician and educator weaves parables, puzzles, and personal reflections to show how mathematics meets basic human desires--such as for play, beauty, freedom, justice, and love--and cultivates virtues essential for human flourishing. These desires and virtues, and the stories told here, reveal how mathematics is intimately tied to being human. Some lessons emerge from those who have struggled, including philosopher Simone Weil, whose own mathematical contributions were overshadowed by her brother's, and Christopher Jackson, who discovered mathematics as an inmate in a federal prison. Christopher's letters to the author appear throughout the book and show how this intellectual pursuit can--and must--be open to all.

From Nobel Prize winner Amartya Sen, a long-awaited memoir about home, belonging, inequality, and identity, recounting a singular life devoted to betterment of humanity. The Nobel laureate Amartya Sen is one of a handful of people who may truly be called “a global intellectual” (Financial Times). A towering figure in the field of economics, Sen is perhaps best known for his work on poverty and famine, as inspired by events in his boyhood home of West Bengal, India. But Sen has, in fact, called many places “home,” including Dhaka, in modern Bangladesh; Kolkata, where he first studied economics; and Trinity College, Cambridge, where he engaged with the greatest minds of his generation. In Home in the World, these “homes” collectively form an unparalleled and profoundly truthful vision of twentieth- and twenty-first-century life. Here Sen, “one of the most distinguished minds of our time” (New York Review of Books), interweaves scenes from his remarkable life with candid philosophical reflections on economics, welfare, and social justice, demonstrating how his experiences—in Asia, Europe, and later America—vitally informed his work. In exquisite prose, Sen evokes his childhood travels on the rivers of Bengal, as well as the “quiet beauty” of Dhaka. The Mandalay of Orwell and Kipling is recast as a flourishing cultural center with pagodas, palaces, and bazaars, “always humming with intriguing activities.” With characteristic moral clarity and compassion, Sen reflects on the cataclysmic events that soon tore his world asunder, from the Bengal famine of 1943 to the struggle for Indian independence against colonial tyranny—and the outbreak of political violence that accompanied the end of British rule. Witnessing these lacerating tragedies only amplified Sen’s sense of social purpose. He went on to study famine and inequality, wholly reconstructing theories of social choice and development. In 1998, he was awarded the Nobel Prize for his contributions to welfare economics, which included a fuller understanding of poverty as the deprivation of human capability. Still Sen, a tireless champion of the dispossessed, remains an activist, working now as ever to empower vulnerable minorities and break down walls among warring ethnic groups. As much a book of penetrating ideas as of people and places, Home in the World is the ultimate “portrait of a citizen of the world” (Spectator), telling an extraordinary story of human empathy across distance and time, and above all, of being at home in the world.

The story of two generations of scientific explorers in South America—Richard Evans Schultes and his protégé Wade Davis—an epic tale of adventure and a compelling work of natural history. In 1941, Professor Richard Evan Schultes took a leave from Harvard and disappeared into the Amazon, where he spent the next twelve years mapping uncharted rivers and living among dozens of Indian tribes. In the 1970s, he sent two prize students, Tim Plowman and Wade Davis, to follow in his footsteps and unveil the botanical secrets of coca, the notorious source of cocaine, a sacred plant known to the Inca as the Divine Leaf of Immortality. A stunning account of adventure and discovery, betrayal and destruction, One River is a story of two generations of explorers drawn together by the transcendent knowledge of Indian peoples, the visionary realms of the shaman, and the extraordinary plants that sustain all life in a forest that once stood immense and inviolable.

A scientific investigation and personal adventure story about zombis and the voudoun culture of Haiti by a Harvard scientist. In April 1982, ethnobotanist Wade Davis arrived in Haiti to investigate two documented cases of zombis—people who had reappeared in Haitian society years after they had been officially declared dead and had been buried. Drawn into a netherworld of rituals and celebrations, Davis penetrated the vodoun mystique deeply enough to place zombification in its proper context within vodoun culture. In the course of his investigation, Davis came to realize that the story of vodoun is the history of Haiti—from the African origins of its people to the successful Haitian independence movement, down to the present day, where vodoun culture is, in effect, the government of Haiti’s countryside. The Serpent and the Rainbow combines anthropological investigation with a remarkable personal adventure to illuminate and finally explain a phenomenon that has long fascinated Americans.
