This essay critically examines faith, defining it as inherently irrational due to its nature of exceeding evidence. Defenders use arguments of unavoidability and unawareness to normalize faith, but this blurs the distinction between faith and rational belief. Key principles of rationality, such as proportionality and evidence-based justification, highlight faith’s contradictions. Ultimately, recognizing faith’s irrationality is essential for fostering evidence-based reasoning and discourse.
