In the timeless classic, "The Art of Happiness," the ancient wisdom of Epicurus is unveiled, offering a profound exploration into the essence of joy and contentment. Epicurus, whose philosophy championed the pursuit of pleasure as the primary goal in life, argued that true happiness is found in simplicity, in the nurturing of friendships, the pursuit of knowledge, and the contemplation of nature. This volume presents a meticulously curated collection of Epicurus's surviving works, including his letters, maxims, and his principal doctrines, juxtaposed with complementary passages from Lucretius, and insightful excerpts from Diogenes Laertius' "Life of Epicurus." Together, they form a mosaic of thought, illustrating the Epicurean stance on life and death, belief and skepticism, and the paths to tranquility. Beyond a mere anthology, this book serves as a portal to a philosophy that has shaped and influenced thinkers across centuries from Thomas Hobbes to Isaac Newton. With an engaging introductory essay that demystifies Epicurean philosophy and a forward by Daniel Klein, "The Art of Happiness" transcends the boundaries of time, inviting readers to explore the harmonious blend of reason and sensation, to question the fabric of their beliefs, and to discover the serenity that lies in understanding the nature of happiness. It is not merely a text but a journey alongside Epicurus, guiding us toward a life marked not by the pursuit of material wealth or superficial success, but by the profound fulfillment of joy and contentment.
