In 1918, the year of his death, Georg Simmel wrote about his "Philosophy of Money": "Certainly, the attempt is heartfelt but imperfect and incomplete, yet as an attempt, it is nonetheless a complete novelty. Unfortunately, this significance of the book has not yet been recognized or made fruitful." This should change fundamentally. The "Philosophy of Money" is now considered one of the great classics of sociology. It marked the starting point in 1989 for the remarkable "Georg Simmel Complete Edition," which is now concluding with Volume 24 after nearly 25 years. The final volume includes essays, texts from his estate, as well as letters and various documents related to Simmel. Additionally, it contains a comprehensive bibliography of his writings, various listings, such as his lectures and talks, as well as a directory of his residences, his ancestors, and images.
