A logic before the Logic

This essay challenges the widespread assumption that fully developed, secular rationality originates exclusively in ancient Greece. While acknowledging Aristotle’s foundational role in the theoretical systematization of formal logic, it argues that other forms of rational, non-mythical thought existed long before the Greek tradition. Focusing on the Egyptian mathematical papyri of Rhind and Moscow (second millennium BCE), the study shows that these documents embody a structured, rule-governed, and transferable mode of reasoning based on explicit procedures, internal criteria of correctness, and abstract geometric-mathematical operations. Although not articulated as logical theory, this operative rationality functions as a formal system in practice. Recognizing this challenges the myth–reason dichotomy and expands the historical threshold of human rationality beyond its traditional Greek framework.
