Discussion of economic reasoning usually uses a two dimensional map to explain theoretical relationships. In a higher level of universality, Paul Samuelson's paper "Economic Analysis Fundamentals" (1947) uses a mathematical method to maximize the balanced behavior of agents, representing a theory transcending graphs doing. This book focuses on the type of statement in economics called the computational theorem that may be rejected by empirical data.
