Quote by Thomas Kuhn

"The transition between competing paradigms cannot be made a step at a time."

"Discovery commences with the awareness of anomaly."

"Normal science does not aim at novelties of fact or theory and, when successful, finds none."

"No natural history can be interpreted as anything but myth."

"The best part of living is knowing you survived."

"The world needs heroes."

"Life is too short to live poorly."

"I'd rather be an optimist and be wrong than a pessimist and be right"
