Arthur Schopenhauer (1788 — 1860) was a renowned 19th-century German philosopher. His work, "The Wisdom of Life," presents a dissertation on points that the philosopher considers relevant for simply living life in the "happiest" way possible. The book is filled with quotations to illustrate the reasoning presented. These include frequent references to Schopenhauer's own magnum opus, "The World as Will and Representation," as well as quotes from Aristotle, Seneca, Shakespeare, Voltaire, Goethe, and many others, along with various popular Spanish and French sayings. "The Wisdom of Life" is a unique philosophical work, as it presents profound content that can be easily understood by the reader.
