30 Philosophers, Chapter 22, Descartes, Touchstone 55: Pragmatism.

Pragmatism values practical application over intellectual accuracy. For my work and for a new look at it, there are only three types: Empirical, Rational, and Irrational. Empirical Pragmatism aligns closely with some traditional definitions of Logical Pragmatism. Both are in conflict with traditional pragmatism’s goal of resolving belief in the irrational. An Empirical Pragmatist embraces what I call the “Grand Rational Framework,” applying pragmatic techniques to evaluate the worth and effectiveness of ideas. A Rational Pragmatist embraces the Grand Rational Framework, but accommodates specific, faith-based beliefs, often in support of their religion. Beyond that, they might hold other faith-based beliefs but are generally cautious about adopting new ones. An Irrational Pragmatist fundamentally does not believe in a core set of common truths, the Grand Rational Framework. They reject the notion that empirical and rational truths form the basis for understanding. Unlike most people, who still value empirical evidence, the Irrational Pragmatist adopts a relativistic perspective. Phrases like “truth isn’t truth” or “everyone has their own truth” often punctuate their dialogue.
