Marshall's economic organon: the One in the Many and the Many in the One.

This article focuses on Alfred Marshall's methodological framework in economics, centered on his concept of the "economic organon," which integrates diverse scientific methods to analyze human economic behavior as part of an evolving social organism. Marshall viewed economics as a tool for tracing the "reasoned history of man," employing analogies from biology, mechanics, and tidology to reconcile static equilibrium with organic growth and evolutionary change. His guiding principle, "the One in the Many, the Many in the One," reflects his dialectical approach to balancing general analytical theory with detailed historical and empirical facts. Despite challenges in fully realizing this framework, Marshall consistently advocated a pluralistic methodology combining induction, deduction, and practical judgment, aiming to adapt economic inquiry to the dynamic conditions of his time. The article argues that Marshall's economic organon remains a valuable, though underappreciated, foundation for addressing complexities in economic analysis and methodology.
