Prologue.

Money governs our values and judgments, harshly testing our perception and weight of life.
Without a philosophical understanding of money, passion for money falls into pathological obsession and distorts into neurotic greed.
Based on the philosophy of money, if life is constantly filled with fantasy and investment, the journey of life as Homo Ludens, the playing man, begins.
Understanding money, which is both a concrete object and an abstract symbol, widely and deeply, is not easy, but it approaches money through the philosophy, symbols, wars, worlds, and aesthetics of money.
Based on the philosophy of money, we examine the concreteness and abstractness of money, focusing on substance rather than pretext, as the basis of benevolence, righteousness, propriety, and wisdom.
With wisdom and reverence for both the concrete and abstract aspects of money, we affirm the beauty of life.
