"The Foundations of Economics" is a significant academic book based on the teachings of Walter Eucken, an influential economist from the University of Freiburg in Germany. The first German edition was published in 1940 and has since gone through several editions, with the current English translation based on the sixth German edition. Eucken was a critic of the historical school of economics and played a key role in reviving interest in economic theory in the 1920s. His works and teachings not only shaped academic discussions in Germany during the 1930s and World War II but also influenced the foundations of modern economic theory. This book provides an in-depth analysis of economic principles and is an essential work for students and professionals in the fields of economics and law.
