"The Philosophy of Disenchantment" by Edgar Saltus is a philosophical treatise written in the late 19th century. The book explores the themes of pessimism and disenchantment with life, conceptualizing a division among humanity between those who accept life as inherently pleasant and those who question its value. It examines historical perspectives on happiness, drawing from various thinkers throughout history and reflecting on the existential struggles faced by individuals. At the start of the work, Saltus discusses the dichotomy of human experience regarding contentment and dissatisfaction, indicating a contemporary emergence of pessimism. He recounts ideas from ancient Greek philosophers, poets, and other literary figures who expressed discontent or despair about existence. Saltus highlights the modern philosophical climate characterized by the belief that happiness is ultimately elusive, advocating for an understanding of life rooted in the acknowledgment of its inherent suffering and the illusions of happiness that often accompany it. The opening sets the stage for a deep exploration of these themes, inviting readers to reflect on the philosophical implications of disenchantment in their own lives.
