“Under normal conditions the research scientist is not an innovator but a solver of puzzles, and the puzzles upon which he concentrates are just those which he believes can be both stated and solved within the existing scientific tradition.”
― Thomas S. Kuhn, The Structure of Scientific Revolutions

“Almost always the men who achieve these fundamental inventions of a new paradigm have been either very young or very new to the field whose paradigm they change.15 And perhaps that point need not have been made explicit, for obviously these are the men who, being little committed by prior practice to the traditional rules of normal science, are particularly likely to see that those rules no longer define a playable game and to conceive another set that can replace them.”
― Thomas S. Kuhn, The Structure of Scientific Revolutions

“To reject one paradigm without simultaneously substituting another is to reject science itself.”
― Thomas S. Kuhn, The Structure of Scientific Revolutions

“Truth emerges more readily from error than from confusion.”
