Patterns Of Discovery by Norwood Russell Hanson

An Inquiry into the Conceptual Foundations of Science

A philosophical investigation of how scientific discoveries are actually made, arguing that observation and theory are inseparable: what scientists see is shaped by prior concepts, classifications, and perceptual patterns, so discovery depends on trained judgment, analogies, models, and the reorganization of experience rather than on purely neutral data or formal logic; the book examines historical case studies and conceptual analysis to show how patterns, suggestions, and interpretive frameworks guide hypothesis formation, experiment design, and theory change, and it defends a view of scientific knowledge as perspectival, context-dependent, and rooted in cognitive and epistemic practices.
